Billet gears for 6spd T-case

[2fnloud]

Yes that is what I said.

I have spoke with Ray and he is not close to releasing anything, I called him because I have a supplier that is willing to make these gears.

Ray told me to go ahead an "run" with this, but I am afraid that this will be a short race.
The first option that Ray suggested was to get just the main gear cut because that would be easy to replace without needing to rebuild the entire T-case.

However the shop could not guarantee that the new gears would mesh with the old gear, so unfortunately this is not an option.

So here is the details:
Shep Transmission (http://sheptrans.com/) is the shop
15-20 committed buyers needed
Gears alone would be 1,700-1,800
Rebuild would be 300-400
lead time 4-5 months

Like I said this probably will not happen but hey I found the supplier and the price, who can commit? Not want to, kind of but....I am doing this no matter what commit

I am just a messenger, all funds would be sent to Shep Transmission directly.

[MR2]

I'm interested, but can you get more info as to what material he's using/why it's better etc etc

[2fnloud]

He would be using the same material that is used in their DSM T-cases: (http://sheptrans.com/products/dsm-awd-transfer-case/sheptrans-upgraded-dsm-transfer-cas/)

Stronger grade material harder to break the teeth. Plus his gear profile is different in the gears themselves, so we could have a stronger gear just by thicker gear teeth (this of course is speculation)

bottom line stronger metal more torque the gears can withstand.

[MR2]

has anyone ever broken one of those gears?

will there be a test set, who's testing etc? (where is Andre') :)

[2fnloud]

Ray has broken a few

[ChargerX3]

Might put this on multiple forums to reach a broader base.

[2fnloud]

I have it in the facebook groups, and a link to it on US3S.org. I do not want to have to communicate through multiple forums, If anyone is a member of other forum groups that will allow linking to 3sgto.org...pleassde feel free to do so.

[ChargerX3]

3si???

[MR2]

yeah throw it on 3si and 3st big time, someone! :p

[2fnloud]

3SI will not let me link to a 3sgto anything.

[2fnloud]

I will post a link on 3sTech

[CoopKill]

3si will want money to advertise a group buy as well. I believe more than here...

[2fnloud]

IF this turns into a group buy I will talk with Alan and do it properly, I am not making money on this , but if I need to I will pay the 50.00 group buy fee.

[ChargerX3]

Who needs links. Just copy and paste the info on 3si. Its more of a gauging interest thing right now anyways.

this is cool that you looked into it, but i could definitely not afford it any time soon.

i have a feeling these would do me more good than billet end housings / midcases

Gnate, start saving for it, I can't do it right now, I know that we are going to have about 6+ months just getting the commited people, then another 4-5 to have them made.

[motomaniac06]

I may possibly interested Im deffinatly going to keep an eye on this thread

[mb7050]

I put a link on 3si but it disappeared real fast

[2fnloud]

I could of told that is what would of happen

[MR2]

Cool, well the info on them looks interesting, is there a thread somewhere where Shep talk about how and why he went about making the DSM gears that ours would be based on?

[Alan92RTTT]

A thread could be put on 3si if it has no links here. I think this is a case where thats not a bad idea.

[2fnloud]

OK Alan I will do a coopy of what I have on my first post

[MR2]

:) like how you think.


and put me down as officially being willing to throw $2k on known tested stronger TC gears.

[2fnloud]

Not that I know of, if you want to sift through threads at DSM forums....be my guest.

[MR2]

lol just bang him out an email asking for more info/the story bro :)

[2fnloud]

spend some time on google and I am not going to bug him about how he started his business, he is renown for race caliber transmissions and T-cases. Would you ask for a back history before Ray tuned your car?

[2fnloud]

:) like how you think.


and put me down as officially being willing to throw $2k on known tested stronger TC gears.

The only test would be the running track record he has under his belt from building T-cases for the DSM market.

[MR2]

lol ok, I'll email him and attempt to get some nice wording to help the group buy

[2fnloud]

Cool beans

[Jesters Deadd]

So did you or your tranny shop do any material testing on the stock gears? just wondering.

[2fnloud]

No, Dave Broomfield noted that the gearing insider the 6spf T-case is different than the 5-speed, there is less surface contact between the two gears in a 6 spd T-case.

with John Shepherd can cut the same profile that he uses in the DSM T-case in a gear set that would fit inside the 6spd T-case.

[Jesters Deadd]

Oh so the strength is added by more contact area. But he also thinks the new material is stronger without testing it?

[mannavr4]

Is this for the one gear or both gears in the tc.

Sorry. Just reread first post and saw It's for both.

manny, you act like you just broke your transfer case or something recently ;)

was it your housing or the gears in yours?

[2fnloud]

He as of now does not even do anything for the 3s platform, so he has not tested anything. I just asked him if he could make the gears, and he replied "yes" and then broke it down to the number of buyers and approximate pricing.

[mannavr4]

Housing is fine. Gears were a different story.

Manny, can you please post up the HP TQ of your car?

What did the main gear look like? Ray told me it is usually the main gear pieces that cause the secondary gear to loose the teeth like that.

[mannavr4]

That is the main gear that Ray is talking about. I didn't take pics of the gear in the tc but it wasn't as bad.

[MeTarzan]

Many of the DSM's still strip the teeth off of shep's upgraded gear sets...One car I know of broke 2 sets in just as many weeks.

We collabirate with a tranny builder and he thinks he has narrowed the problem for the DSM's down to the cover on the housing is flexing letting the gears spread apart thus stripping the teeth off. As well as the housing flexing causing the broken output shafts as we all know. So we came up with a combo Brace and Cover replacement.

We have only done limited testing on our solution but it has done amazing so far. I'm sure if any real interest would be for something like this for our platform we could make it fit as well.https://sphotos-a.xx.fbcdn.net/hphotos-ash4/331244_365001253572691_404617528_o.jpg

I'll piss myself if it is just the TC gear being pushed out of the housing

yeah but thats a lot more expensive....plus is broomfield even making them anymore??

he never made them for the 6 speed


that looks like more than $600 that the 5 speed cases were? no?

im glad manny posted up. its time we start finding solutions because these cars are very quickly becoming powerful enough (with the turbo upgrades out nowadays) for a lot of people to have the same issues

I wasnt aware the ones he made were for jsut the 5spd. And the last pricing I saw was $800 for the main and $1400 with the mid housing but I could be wrong....We havent gotten a set price yet but the will probably be close to $600.



The question I would want to know is what material is the DSM T-case housing made out of? Aluminum or steel?

The main housing and cover is Steel, the mid and tail housing is aluminum

[Permanent grin]

Hi guys, sorry I'm ate to the party.

It sound like Shep is on the right lines, although Elite are looking at gong further than the proposals here. Unfortunately, that also will carry a higher price tag. I already ordered one from Elite but had to put it on hold when I smashed my dog box.

Anyway, I don't want to hijack anything but will be watching with interest.

André

[2fnloud]

I was under the impression that the 6spd T-case was all steel, is this correct?

Only issue i see is when making the amount of power you break the 6spd gears...the 5 speed is a better trans :/

Im 50/50 on putting my name on the list at the moment.

Jason

[2fnloud]

do it
do it
do it

aint peer pressure great!!

[MR2]

my way of looking at it, we won't be actually throwing money ANYWHERE until it's tested and proven to actually be stronger, so your money is safe, and at only $2.5 that's looking very cheap compared to replacing ANOTHER TC and repairing whatever damage your GB takes when the TC shears off.

if your running say 600hp+ with a hard clutch and like to beat on your car your name should be on this list (assuming your not selling your car in the next year) do it for the rest of us :p

[JasonY]

Well, unless steve can get us a price on a single unit, i dont think anything will be proven since i dont think we'll get 15 buyers for an unproven part that costs this much cash.

Absolutely, before I hand over my Cash I want a Guarantee that one will be sent out to our glorious breaker of all things metal (Andre) and he will get the bash it for atleast 3 drag meets, then take it apart and check for wear/damage etc.

my name is on that list only if the above happens, we have had too many products that ended up worse than stock.

Weeee bit off on your pricing, 950 from Pampena and i think 850 is the current GB price through Pampena.

Jason

[niterydr]

I have a feeling these gears will do nothing in a stock housing. Has anyone measured deflection of the aluminum on the 6 speed housing?

In the 5 speeds the weak link was two bolt hole passages in one of the corners that were very close together, 99% of the cracks/broken housings started there. I wonder if there is enough flex in the 6 speed housing to allow flex, and then the gears unalign...BOOM, especially with the narrower surface contact area of the 6spd vs. 5spd.

[JasonY]

Are you thinking the mid housing is flexing? I doubt the smaller gear set in the considerably bigger/heavier/strong iron housing is flexing much if at all.

Jason

[niterydr]

Maybe the mid, but I would wager that the breaking of the gears is from temporary misalignment versus raw power, but I could be wrong.

I highly doubt that John is going to go through a test phase. To me stronger metal = stronger gears.

I am confused as to why we can not use a 5spd T-case on a 6spd trans...are the two gears inside the T-case not spinning at the same speed?

[JasonY]

different reduction ratio.

no.

[MR2]

Ehhmm, ok Shep is telling me (via email) that there is no way to complete a testing phase due to the cost of it, so I'm now asking for an explanation as to how/why this new material will be stronger.

I know a guy that has I could ask him. He measured the deflection of the stock 6-speed endcase, transfercase cover, and then billet 7075 aluminum. His fix was brazing some aluminum blocks/stock/whatever onto the endcase, transfercase cover, and he also did something for the mid case. It increased the flex 6 times over stock and he's guaranteeing his bell housing, endcase, and transfercase won't come apart. We'll see. He only had DR-500 turbos, went through two RPS C-C clutches, 3 6-speed trannies, and a few stripped gears/broken 6-speed cases because he drives his car ridiculously hard as in high rpm clutch dumps not because he's stupid but because he wants to build it to handle the power. He's a veteran machinist and knows what he's doing with a huge 85,000 sq ft shop at his disposal off hours.

He's planning on selling some endcases, transfercases, degreed stock cam gears, a custom intake manifold, and a few other parts he comes up with.

[MR2]

My Last few emails from Shep


Hello,
No I do not have any threads or data that is publicly released as we are still in the testing phase with our latest gears.

The dsm has a weak output shaft so in the past the fix was to machine the existing output gear and electron beam weld a larger output shaft. This was very expensive and in the end we would still strip gears from time to time.

John


I totally understand where you are coming from but it is not possible to make one for testing as it would not be feasible to set up and just run one set.

To be clear I was approached about making sets, this is not a market I plan to get into. If it were then yes I would be the one testing them and assume liability.

Thanks
John


Being that these are two totally different gearsets any testing done with the dsm may not reflect or help with the 3si gears. The material is set in place and there is only so much that can be don’t with the tooth count and tooth profile being that we must stay with the oem transfer ratio.

The dsm set has already been run and in my hands, I have attached a picture.


These parts are made from certified high grade EN36 steel, quality heat treat, special tooth profile resulting in smooth radius in root of teeth, shot peening. The oem gears are 8620 at best,

It would take destructive testing to give you an actual percentage because it is impossible to know the exact heat treat and quality of metal used in the oem set.

[Jesters Deadd]

I highly doubt that John is going to go through a test phase. To me stronger metal = stronger gears.

I am confused as to why we can not use a 5spd T-case on a 6spd trans...are the two gears inside the T-case not spinning at the same speed?

I thought you said he didn't test the stock gear strength?
edit:saw above post. Information noted.

[futurevr4man]

well saying that stronger metal = stronger gears isnt exactly true...

every metal has its own yield strength (the amount of strength before it shears or 'breaks'), it also has a modulus of elasticity (stiffness). on top of those, there is weight, and a lot of other factors that play into it all. my point being, even if the metal is stronger, its not always better. there is a reason why there arent gears made out of diamond... yeah its very strong, but its so hard that its too brittle.

with that being said, im sure shep knows what he is doing with metal selection, i just wanted everyone to take a second thought about saying 'a stronger metal means stronger gears'

[MR2]

Thankfully we can always wait a bit and see how the DSM gears go :)

[Ninja Performance]

I have also broken gears in a 6 spd transfer case.

Shep has been making DSM gears for years, google his business name, see for yourself.

[MeTarzan]

Shep has been making DSM gears for years, google his business name, see for yourself.

Actually his upgraded shafts have only been a welded stock gear onto his shaft...Only recently has he started actually making the gears, AND they break the same as welded ones.

If you look at a lot of the failures the edges of the teeth are broken off due to the gears being pushed away from each other. We fixed that problem with blown up DSM rear diffs by upgrading the covers to add in load bolts to keep them from flexing. Which a better cover is probably a better bet of keeping the TC from failing as well.

I was not aware that the new upgraded gears had actually been put to the test yet...

My friend that I work for is very well known in the DSM community and I guess we could have a bit more information from the people that are running/testing the parts for Shep and hasn't made public since they are the ones that are putting our parts to the test as well.


IF I read that right you are talking about rear diffs, how can this be applied to the T-case?

the external brace with an integrated cover as I posted in my prior post (#48) it will stiffen the house and should not allow the flex and separation of the gears.

I never really got any definite interest in them but if people really want them we can make them.

Overkill or not...INTERESTED.

[2fnloud]

I even have a good T-case sitting that could be shipped to you if need be to develop the prototype

[MeTarzan]

theres no issue if its overkill if someone will buy them....i mean the dsm one was made on recommendation of a trans builder with a mid 9 sec full weight 2 G eclipse and this season we will have them on a few other Fast dsm's.

i have the tcase already so development isnt a problem...just demand.... i guess i can start another thread to get actual interest on them and we could have the first one ready pretty quick (~2weeks)

[MR2]

before we hop onto the brace idea, do we have any proof that the stock case is flexing? anyone looked at the broken stock housings to see if there is any sign of this?

[2fnloud]

How about just based on the conversation I had with Ray, when I first started this thread? He suspects that there is just enough flex to pull the T-case gears far enough apart to cause the failure.

HE backed that up by explaining that in all the grenaded 6spd T-cases that he seen it is the main gears that have been stripped just about clear off. Manny even posted pics of his T-case main gear, and it's damage was exactly as Ray explained it.

Has anyone in the DSM family put one of these on with just stock T-case gears and beat on it? Would be curious to know if adding just the brace added to the longevity to the stock gears.

[MeTarzan]

well that is exactly what the dsm tcases do as well and so far im pretty sure the only tcases that these are on are on stock gears.....im going to go ahead and pull my tcase and get this thing rolling

[Chris@Rvengeperformance]

why don't you guys just get the midcase cast in steel then? toy-rific is stilling casting 5 speed cases.

[2fnloud]

well that is exactly what the dsm tcases do as well and so far im pretty sure the only tcases that these are on are on stock gears.....im going to go ahead and pull my tcase and get this thing rolling

What did the DSM brace and up costing, I remember you guestimated 600 earlier in this thread.

[MR2]

is the DSM brace pre-loaded? did the DSM guys go with a brace or a full replacement?

[MeTarzan]

What did the DSM brace and up costing, I remember you guestimated 600 earlier in this thread.

The DSM on is $450 and I'm guessing unless there is some major roadblocks then ours should fall in right around the same price.

The cover part is to exact dimensions of the stock cover only thicker so it is preloaded with shims the same way. We dont sell a full replacement just the Brace which replaces the cover and attaches via the mounting holes thru to the trans and then to the mid and tail housing to keep the tcase from flexing

[MR2]

Right, this sounds like it'd be worth shipping a test unit to PG to play with :D

while I am cynical I would LOVE for it to be proven that it's just the case flexing

and considering how much it's costing him each time he pop's one, I'd say he'd be happy to pay whatever the normal price is for one

[CoopKill]

I agree that this is most likely a flex issue. It would be nice if some inspection could be done to the damaged units to see where the flex/failure is happening before creating a solution in the dark.

well like i said in my prior post we developed this in conjunction with a trans builder in the dsm community so we arent going at this blindly. We have inspected many gear sets and housings and most common thing is the teeth are stripped off the gears and the covers have fractured leading us to belive that the problem is the gear is separating. We only got the dsm one out just in time for it to be tested at the DSM Shootout but it will be on multiple 9 sec cars and at least one 8 second car this year. So that will be our major testing bed for the brace. There are other companies that make braces similar to the strap style of Nelson but people have still blown their tcase and actually tend to break them more often with said style of brace.

so our solution was to replace the stock cover which is only about 1/4" thick with a piece that is 1" thick at the bearing and also supports the rest if the tcase from flexing/warpping from front to back

[MR2]

Right! lets have one whipped up tested :)

[mannavr4]

I was just informed of this thread. I am willing to try anything as there is no tested solution rite now. 6speed tcase is only good for 1.6 60ft. Any faster = broke.

This guy: My DR1400DBB daily driver build - 3000GT/Stealth International Message Center (http://www.3si.org/forum/f35/my-dr1400dbb-daily-driver-build-512516/)

and considering how much it's costing him each time he pop's one, I'd say he'd be happy to pay whatever the normal price is for one

yeah I would love to have PermanentGrin have one of these on to "play" with,

[DK77]

Based on what Ray posted here 3000GT/Stealth International Message Center (http://www.3si.org/forum/f13/nocars-product-indestructible-but-my-other-s-isnt-341017/) it seems that the gears may be spreading just enough to cause them to strip. Regardless, if the brace MeTarzan is working on would preload the t-case to help keep the front and mid housing stuck together fully, it should at least help with people stripping gears.

[Permanent grin]

I sent Me Tarzan a PM offering to test these right before Michael suggested that I should be the proving ground.

I am waiting to hear back.

André

[MR2]

Andre, I did not mean to be a bit forward suggesting you should be the first buyer, I was merely suggesting that out of everyone I know who still has a high powered car, your the only person I would trust to have it put through the ringer and trust the results :)

on another note, the reason I'm so keen for plenty of pre-load is not in this case, but in alot of other products, when they are attached, by the time they take any load the part they are attempting to protect has already given way... (I know I'm stating the obvious here)

[Permanent grin]

No worries chap, I actual saw it as humorous.

André

[mannavr4]

I've broken 2. 1 years ago after many launches and just over stock power and 2nd last year. I havent broke more because I was always grenading trannys. this has got to be my 8th one I think but its finaly fully built. so now after building my trans I hear about and experience the tcase problem. If I had known before I would have built a 5 speed. I'm not switching now after my tranny cost me about 10k between purchase and labor. I've stopped launching the car untill there is a fix.

[MeTarzan]

OK well we had our mill go down and is getting repaired right now but here is the preliminary drawing of the cover we are going to make. Its not going to be a full brace like the DSM since it seems we don't have a problem of breaking the TC output shaft. We were very surprised at how little material is on the cover, the end cover is only .1435" thick where the bearing sits. Our cover is going to be 1/2 in thick at the bearing race and should be able to clear a 4" exhaust. We also were very worried that the bolts that hold the cover on are only 8.8 M8's, I'm not sure what Getrag was thinking not putting hardened bolts. So if what we were thinking of the cover flexing could have been made worse by the bolts possibly stretching slightly as well.

[2fnloud]

What are we looking at in price?

[MeTarzan]

What are we looking at in price?

not 100% sure yet since we havent ran one to know how long it takes but rough estimate is 300ish range with the hardware

[2fnloud]

interesting.

[futurevr4man]

in replacing this, are there any shims or anything, or is it just pop off old one, pop on new one? im sure there are shims and whatnot... life is never that easy ;)

[MeTarzan]

the bearing fit is made to the same specs as the stock cover. The ones that have been installed on the DSM have just reused the shims that are in the stock tcase and are within spec for the preload. We would reccomend you measure it prior to installing just to make sure the preload is proper

[DK77]

At around $300 I am in for sure for a little more peace of mind.

[Permanent grin]

Best estimate at lead time? Is the plan for me to be a guinea pig / proving ground prior to the main run or just a group buy?

André

We can have one done relatively quickly as soon as the machine is back up and operational. It would make me feel better if you were to test first. How quickly do you think you could get some testing done on it?

We are aiming to be ready in time for the first round of the Jap Drag Series on 27th April.

André

[super95awd]

Trial by fire huh? :) We should be able to accommodate that!

[Permanent grin]

:lol7: Unfortunately, due to parts delays from a couple of areas and discovery that the ARP main studs are not man enough for the job, we are way behind where we wanted to be by this stage. It is going to be right to the wire in getting the car ready. We had originally planned to do a shakedown run on 12th / 13th April but I can't see that happening for two reasons. 1) the new fuel cells, pump and lines aren't going in until the 1st week in April and 2) the weather is shocking over here at the moment, we have snow and sub zero temperatures all over the country!

Still, if it all stands up the cover plate should get good rep for sure :wink:

i would also be in for $300 for safety, but if you could do a group buy, you would probably get a big payout all at once!

hmm what's wrong with the main studs? are they stretching? also someone said supra head studs are same as out main studs so you can get some L19 or 625 head studs to make them stronger. they only come with 14 studs for the kit so you need to buy 2 more studs with washer and nuts.we got to get a company to make harmonic damper to reduce stress on bearings crank and such.no one in other platform make big power with out using these. also i read Ray said he fixed his tc gear issue by running stickier tires up front so the front can carry more load and reduce stress on the rear tires. you can do that by running stickier tires up front or run less air on the front compare to the back.

[MR2]

didn't you go in on the A1 stud buy? swear we told you ARP are crap :p :p :p

[mehrshadvr4]

He's talking about his main studs. he did order A1s as far as i know.

[Permanent grin]

Indeed, I now have a1 head studs. I had Cosworth make some custom main studs in a superior material due to the ARP main studs stretching which in turn allowed the crank to flex. When it flexed it put a lot of pressure on the outer mains. I have had the crank ground and the block / ladder frame line bored, we're also tightening the clearances on the big ends whilst we're at it. Hopefully we will be assembling next week.

I'll never trust another ARP product though!

André

ps For some reason, I'm not getting the email notification for replies

[mehrshadvr4]

It's crazy to see that crank flex. it's a 8000hp crank and very strong.

[MR2]

I think Ray said his cranks are good for 2k+ HP, the 75 re-used 800 max. not sure who added the naught :p

[mehrshadvr4]

that crank is made from same material on top fuel drag cars. 4340 crank is good for 2000hp.

[TurboSinceBirth]

Plus that was THE old motor Matt Monett ran almost 1100AWHP on and set the world record with a mere archaic ARC-2 piggyback where he didn't even touch timing. It's kind of hard to see the lower power on this car isn't a result of the tune, VE of the motor, crappy cams, or backpressure somewhere in the system that led to the crank flexing. It just goes to show the right parts and a critical tune by someone that knows what they're doing to the T leads to the most power while doing it safely. It's really not hard to screw something up when making bigger power.

It just goes to show the right parts and a critical tune by someone that knows what they're doing to the T leads to the most power while doing it safely. It's really not hard to screw something up when making bigger power.

It has been confirmed there was nothing wrong with the tune and the guy that tunes it REALLY knows his stuff. 8 years ago he built and tuned the world's first Ford Sierra Cosworth to break 200 mph in the standing 1.5 mile. In fact it ran 206 back then.

What happened was the ARP studs were put in as an 'upgrade' over stock and torqued to 90 ftlbs to bring the tolerances into line. The studs yielded even though they are supposed to take 90 ftlbs. Like I said I will never trust their products again. With stretched studs ANY crank would flex on ANY tune if it is not supported properly. I had the ARP studs tested at cosworth and the guy said their surface hardness was better but they were never going to handle 800 HP!! So I now have a custom set made that WILL take a lot more power.

As for the reason for the power being down last year, I made it quite public that there was a massive exhaust side restriction that we would be addressing this year which is exactly what we are doing. Better cams, screamer pipes (on Ray's recommendation), better exhaust system and solid internally shimmable lifters. The hydraulics were not refilling quickly enough with the cam profiles that were in there and 9000 RPM, hence the cauliflowered valve stem tips.

Where the car is at now is the gearbox is back today and we are putting the engine back together this week. Not far from getting it running now.

André

[MR2]

Awesome to hear PG :D I feel your's will be the true test :D

[Permanent grin]

So close now. I was speaking to the guy who is building the transmission control unit and paddle shift last week about flying him down to set it up in about 10-12 days time hopefully.

André

[mehrshadvr4]

You know speaking of lifter you probably lost oil pressure when you stretched the studs because crank got farther away from crank and that's why the lifter bled out. solid lifter will help you to get a bit more power but it'll be hard to set it up and I heard some do break which it sucks. any picture from the main studs. how much power are they rated at and how much are they charging you for? I might get those too if they are stranger than 625 head studs for supra.

[Permanent grin]

You could be right on the oil pressure although the logs showed great oil pressure throughout and the big ends were in mint condition. As for the lifters these are solid tops not screw adjustment type, so are much stronger. The shims for inside the lifters are being custom cut so should be 100% correct.

Unfortunately I have no pictures or stats at the moment for the main studs and won't know the final cost until the bill comes in. I will see if I can get some info though.

I am getting very concsious that we are de-railing the thread here though. If we are to discuss these kind of things, perhaps we should do it here (http://www.3sgto.org/3000gt-stealth-gto-related-topics/4443-my-dr1400-project-started-today-43.html)


André

[mehrshadvr4]

yeah but it's been a while since you update it. anyway. if you going to take your TC a part to try this cap send your gear to get cryo treatment and then WPC surface treated. i know WPC helps to strength the surface area and make them surface super slippery which reduce stress and friction on the gear and they run cooler. I'm going to send them my bearings,wrist pins and piston rings to them. you can do this to the entire rotating assembly or even you gear box moving parts like gears ,synchros, sliders etc.
Check these videos out.
no oil on these parts at all

It probably does if you do the gears. not sure if we can apply this to our synchro since they are not made out of brass.

Thanks! It will look way better once I lay all the finishing tool paths down on it.

It is 6061-T6 aluminum.

[mehrshadvr4]

Is it possible for you to make covers that have cooling fins on them for the TC and rear diff since you can do pretty much anything and our diff and tc hold very little oil or maybe even help it hold more oil? :D
something like these.

[super95awd]

I have no problem doing it if there is some interest. Your guys' diff covers are pretty good size, so they wouldn't be cheap. I wish I could make girdled diff covers like I do for the Evos and DSM's, but your bearing setup is different.

[super95awd]

Little test fit before the top side.

[J. Fast]

Alright let's do it!

[anyonebutme]

I like it.


BTW, don't worry about a finned rear diff cover. Unless you have a KAAZ rear diff or are running the wrong fluid, it doesn't get that hot. VCU limited slips don't create near the heat of a salisbury, like what's inside the BMW diff pictured.

that's fair, can I ask if you were re-making other parts of the drivetrain, what you would change about them? we do have the TC venting issue, any issues with heat from gearbox or ??

Fasteners are on the way and then this will be shipping out to André!

[anyonebutme]

FWIW, took some IR temps at the track on saturday. This has nothing to do with the case stiffening project, but figured I'd post them in here since Mike brought it up.

Transmission case bottom: ~180 degrees F

Rear differential cover bottom: ~180 degrees F

6-speed transfer case bottom: ~210 degrees F

I would hazard to guess oil temps are about 20-50 degrees hotter than the case temp due to air cooling effect. Rear diff temp is acceptable, Xfer case is fine with good fluid, wouldn't hurt to duct some air to it if doing high speed events, but not worth adding a finned endcap to. A heatshield to block exhaust heat will go farther.

[super95awd]

Steve, a good question honestly, I would still like to one day (in my dreams) fit a 3.5" pipe through the TC/Sump gap :p

[super95awd]

You'll be fine as long as your downpipe isn't routed ridiculously. Since I counterbored the fasteners, the overall thickness doesn't come out much past where the stock fasteners did, but it is significantly thicker where it needs to be.

[Jimvr4]

Cover looks great but I don't get it. How is a billet 6061-T6 cover stronger and less flexible than the stock cast iron cover? Or is it just to increase the pre-load on the bearing?

Cover looks great but I don't get it. How is a billet 6061-T6 cover stronger and less flexible than the stock cast iron cover? Or is it just to increase the pre-load on the bearing?

The cover is cast aluminum on the stock 6-speed xfer case.

[Broomfield Racing]

The cover is cast aluminum on the stock 6-speed xfer case.

It's cast iron/steel.

[Jimvr4]

It's cast iron/steel.

Pretty sure that's right. Going to check whether a magnet sticks to it when I get home.

If it is cast iron/steel then why would billet 6061-T6 be an upgrade?

[Broomfield Racing]

The stock cover is quite thin. Could have some flex, but it's likely the fact that the gear face is about 20% smaller. Hopefully the thicker cover works out for him though. I wish I still had a 6 speed tcase, I could see if the stocker flexs easily.

[2fnloud]

Magnet did stick, just checked.

[Jimvr4]

Indeed it is cast iron. A few googles and I found the tensile strength of malleable cast iron is 52 ksi while 6061-T6 is 40 ksi. So I guess if you make the billet cover 30% thicker then it has the same strength as the stock cast iron. Sorry if this is just rehashing what everybody already knows.

It does flex. I already experimented with a friend on his 97 VR-4. I'd have to ask him again how many thousandths of an inch it deflected under load. We made the stock cover thicker, beefed up the transfercase to transmission mounts, added a bell housing brace, and made the transmission end case thicker. So far no issues but he is still going through RPS C-C clutches. I think the thicker transfercase cover will go a ways to helping the gears stay together.

He basically welded/epoxied more material around the two outside bolt holes around where the axle goes through. We didn't think it was absolutely necessary but he wanted to make sure there was no movement or shock in that area if the transfercase stripped gears causing everything to rotate before failure.

Agreed Not seeing how more material would help...anyways what is the estimated torque your friend has, and just how rough is he on launches? Would guess straight up violent If he is ripping through C/C clutch kit.

The stock cover is cast iron and extremely thin. I don't correctly recall the exact numbers, but this cover is somewhere in the realm of 300-500% thicker right behind the bearing race. To add to that, the cover is also being held down by the M12 t-case to trans bolts along with upgraded 12.9 hardware for the M8's. And yes, the stock cover does, indeed, flex.

[hated]

spend some time on google and I am not going to bug him about how he started his business, he is renown for race caliber transmissions and T-cases. Would you ask for a back history before Ray tuned your car?

Damn skippy! Hellafuckenyes I would!

[Chris@Rvengeperformance]

Any updates?

[2fnloud]

Nope, nobody was happy with the source I found's credibility, they all wanted R&D and proof. Problem is my source wasn't looking for a market, he was willing to make for a need with 10 committed people.

I guess being well known for building T-cases for extreme built drag DSM's wasn't enough.

Not strictly true. I still have the cover. We had a bit of a problem in that the outer bearing race didn't drop in nicely, things were a bit tight. Better to tight to loose, so we have now had it machined out slightly to accept the race.

I have also had the bevel gears put through several treatment processes as well. Although nowhere near full power, I aim to be trialling the transfer case on the 11th and 12th of October. With any luck I will be running around 5 to 600 hp, I will update this as information becomes available.

This is by no means dead.

Andre,

The custom made billet bevel gears us what is dead. Glad to hear you had your gears treated, I too have thought about this so I would love to hear about your results. Thank you for "keeping at it"

First time seeing this thread. I'd like to get a solution BEFORE I put my car back on the road and break a T-case.

[Unknownvr4]

Anyone know if he still grenaded the tcase?

[2fnloud]

I have heard nothing.

[Permanent grin]

The current situation is that I am waiting to get the engine on an engine dyno (someone got slotted in before us!). The car is due back in about 2 weeks from having a complete body made from carbon kevlar, so I would think we will be at least a month away from results. Sorry.

Good to know that this is still developing

Thanks for the update!

I probably will not see my billet stroker engine until the end of summer, but I'm hoping for results before I fire it up.

[DK77]

Haha. Only Andre. Well I would have tested this, but I'm in the middle of having a complete body made from carbon kevlar.

You sir are nuts, and it's glorious.
