DR750's V1 guess the dyno

Appointment is for December 5. The car is completely together and as of today has zero issues so this is not a hype thread. I have 2 hours scheduled on a Dynojet (Battleground) strickly for power pulls up in Atlanta. I will start with pump 93 plus meth injection and once I feel it's close I'll have 5 gallons of C16 to pour in. It will be pushed hard. Complete mod list below.

If there are any other setup questions that I may have missed fire away. This setup is significantly faster than my old 19T setup.

Jeff

Everything looks great, just confused about the 225's?

I say high 5's

660...

If you push it really hard.. Nearing 680 maybe. If you don't I'd say 630.

Awesome thread! I'm really excited for you, with the amount of time and how meticulous you are I have no doubt you will do well. With that being saI'd I'm guessing 630-640awhp.

637! 637!

I told Jeff 638 earlier...:p

If you push them past 30 psi and have enough fuel for it provided the turbos are making more power I'll hope for 680AWHP also.

That's a great question. When I first bought the car I went to a local wheel shop and picked this design of wheel. They had all the specs from the car and the factory wheels in front of them. Somehow the salesman goofed and ordered 7.5" wide wheels instead of 8.5". When they arrived, they didn't test fit the wheels for brake clearance and just mounted the tires. After finding out the front calipers required and additional .75" to clear he offered to get me wheel spacers for it at no extra cost. Me being an auto dummy at the time (yes, like everyone else here, owning and building a 3S has taught me a lot) I never questioned the wheel size or the fact that there was a wad of rubber sticking out beyond the wheel giving it a truck tire look. They mounted the 245/40/18's to a 7.5" wheel and it looked like shit.

He had the spacers custom made, at least that's what he told me, with the lugs built into them. The spacers bolt to the hubs and the wheels bolt to the spacers so no real extra stress on the studs. There may be a little extra on the actual hub bearings because the mounting point has now moved out 1" but it has been like that for going on 6 years now.

Back on track, they put the 245/40/18 wheel/tire combo on the car and while I didn't care for the way it looked I figured I would drive it home like that and see if it would grow on me. It didn't, and I went back complaining about the look. They worked with me because pretty much once I drove away I accepted the package. They basically sold me another set of tires at cost and put the "stock size" tires on the old stock wheels. They went through test fitting a couple tires before I was satisfied with the way they looked. That got me what I have today, 225/45/18's on 7.5" wide wheels.

I buy the highest traction rated tires that Kuhmo sells and they stick pretty well in the heat.

So far testing on the street with race gas I have gone to 28psi. The gains started to diminish so I stopped adding boost. This was with the DSBC set to 93 in GA summer heat. It hasn't had the race gas in it since the weather changed.

Not intended to give a sleeper impression.

I always over shoot these guesses, so this time I under shot it.

v1 with the 11 blade turbines?

640-660 - max most likely



9 blade =

680 awhp on max kill, or at least thus far.

Yes, V1 11 blade design.

Has someone made 680 on the 9 blades?

Jeff

You don't have traction issues going WOT in 2nd or 1st?

Have there ever been any factual dyno evidence of 12 vs 11 vs 9 blade wheels or is it all just heresay? Anyone except sinsvr4?

Only 1st so far. 2nd gets touchy feely depending on the amount of bumps in the road. The cooler weather really effects these tires performance. They are VERY sticky in the heat.

Jeff

591 at the flywheel.

595whp SAE. 625whp uncorrected. The weather in Atlanta tomorrow will be 1500 feet below sea level hehe. Oh my god I would dream to feel my snails hit at -1500 ft. So jealous man, good luck!

Can you link some info you used to get this DA?

I know where I am located near Ft Benning my elevation is 300ft. I don't know what Atlanta's elevation is. Battleground is just north of Atlanta in Smyrna if your handy calculator can find that. I would assume anything under 0 would be covered with water.

Jeff

There are places that are physically below sea level, but they obviously can't be on the coast :)
However, DA is the relative density of the atmosphere which is affected by weather so it can easily be below sea level even if the ground physically isn't.

Density Altitude Forecast for Atlanta Dragway

I also want to clear the air here as there have been some not so good reviews from tuning done at Battleground. Their sole purpose in this adventure is to provide the testing equipment. I built my car from the ground up. There was nothing subcontracted out here. Everything put together with my hands and polished with my hands. That being said I am the only tuner to destroy it, if it happens. They require one of their people operate the car on the dyno and that is the ONLY thing they will do. I feel right now the tune is set for both pump and race gas. I will simply raise the boost pressure with the race gas added.

The timing map is fairly aggressive and since Greg E has enabled the CEL to come on at a preset knock count through Chrome, the driver will be instructed to pull out as soon as he sees it light. We will then go back and reevaluate what needs to be done. I scheduled 2 hours to tweak if needed but I feel I will only need 5 pulls max. 2 on pump and 2 with race gas added and maybe 1 more if not convinced it's at the edge. This is a raised compression engine so seeing 30psi is probably not going to happen. I won't write off the idea of it but once I feel it's getting close I'll stop and hopefully enjoy my drive back home he he.

Thanks for that!!! I think the appointment was for 3PM. They have a 1.5 month lead time for scheduling dyno time so it was scheduled nearly a month ago as of today. Thanksgiving pushed it out a little further so I snatched the earliest date that fit my schedule and theirs.

Jeff

Great mod list. Car looks tits. How's the car feel? Only thing holding you back that I can see would be the 680 injectors.....

Thanks!!! It is an absolute hoot to drive. Like I said before it is SIGNIFICANTLY faster than my old 19T setup. It's very rigid because nearly the entire powertrain is solidly mounted.

The injectors run at 67-68% DC up top according to evoscan (I never actually crunched the numbers). 1600ml/min straight methanol helps a little in that department

Jeff

What compression ratio you running in engine?

Do your own tuning and watch the operator closely. Not sure if you've seen George Benson's thread on the other website. George does have some bad luck, but I've also had my own experiences with Battleground. I had them install an AEM EMS on my old 95 Vr4 in 07 and their master tuner Dan charged me 16hrs (dyno hrs) to tune it and the car ran like shit. It would idle @10.6 and 10.0 @ WOT. A very bush league operation..

Yes, I read his thread. I asked if they would let me drive it but, they said no. Top Speed would not grant a "tuning session" as they only offered the three power pulls and get off. I've done the 3 pulls and get off elsewhere before and it's a joke. I like paying for time so they won't rush me. Battleground offered time so they get the business. Regardless of reputation they are the closest Dynojet facility and as long as the driver obeys the CEL everything will be fine. I will be watching over his shoulder and haven't posed the question yet but, would like to be in the car during the pulls. At least then I can watch the loggers.

Jeff

Interested in seeing where the 680's get you on pump/meth.

590awhp.

So prove us wrong;) Have you posted a VD graph and I missed it?

Ohhh...the tension!! :D

I'll raise to 640awhp if you go beyond 28psi. For some reason I thought this was going to be 93 plus meth only. Didn't catch it was c16 plus meth.

Instead of "rolling eyes" at any guess below what you think, why don't you dyno then post what it is....or a VD graph to give us something.

Yeah...I know Jeff can provide VD graphs..:) You may be surprised...its pretty healthy.

I want to see this car blow the Chrome ECU dyno record out of the water! Right now its at 600whp.

VD 700+ :suspect:

Seems like that would be high for a TD-04. When you start winding it up the reversion and heat gets really wild. Hard to say the hot side can take it. Unless he can push past 35psi I don't think we'll see 700. It's like an EVO wheel so 20psi-500 25psi 550 30psi 600 32psi 625ish. The big danger is crystallizing the exhaust dumps when you start making all the heat from the over exerted tiny exhaust frame.

Posting VD graphs really defeats the purpose behind a "guess the dyno thread". I have posted pertinent mods and have entertained any questions to the best of my ability. IMHO, any guess below 600 is bogus when stock engine 750 cars in draw through are making that. To familyMAN, that deserves a roll of the eyes coming from someone's opinion I really respect on here but you also didn't read all the details so I guess shame on you, lol. Now, stating pump plus meth numbers under 600 are more than welcome because I do live in reality. This car is blow through, built heads, a FMIC kit that won't restrict it like stock IC plumbing and IC's, you might as well say wide open exhaust, and will be pushed on race gas. All that being said, here are two pulls from tonight as requested. These are temp AND baro corrected. I have for the longest time had a hard time believing VD DJ graphs because they just seemed to be inflated. I have only been correcting with temp up until today. I have been using the virtual dyno as the dyno for my graphs because they are 1.00 CF vs the DJ's 1.09 CF. Baro correction really brought these to where I feel they should be and these graphs I actually believe are close. Can you believe that Nomie? LOL. Uncorrected netted a +30HP bump FWIW. Pump 93 plus meth only.

Had a couple counts of knock up top on the red graph but, negligable in the grand scheme of things other than the timing it pulled out. It flickered the CEL light and that was it. The light is set to 5 counts. The blue pull had 3 counts and then went away. No light on that one. These pulls were done 3 minutes apart on my 2 favorite interstate spots. The blue was the second one.

I need to come up with a better way to get the meth delivery more consistent. The logs both read the similar IDC's and seeing as boost was very close the meth injection has to be the difference in AFR. The other thing to make mention is that these turbos like to surge in 3rd pretty bad under 3800-4000RPM in WOT. I have been trying to see if I can get away with pulls a little earlier in the RPM band but I don't think it'll happen. Once the RPM's climb they settle down but if I simply start the pulls from 4000 they are clean.

For the mathematicians out there, my MAF Translator logger has seen up to 672 g/s of airflow (not these pulls) that I have actually logged. I really don't log it too much anymore. It slows the logging rate a little on evoscan I think, and the translator is zeroed so nothing really important there anyway. I didn't log it this summer at all when I was leaning on it hard with the C16 added but, recently the conversation sparked interest to see a correlation between Hz read from the ECU's logs vs the actual g/s the MAF sensor is showing on the Translator.

I'm really hoping the weather will cooperate on the actual dyno day because this car is something else when the weather is right. J.Fast really hit the nail on the head when he brought DA into this thread. You can really tell in the seat of the pants when the weather is good and when it turns to crap. Tonight was a dreary night IMO based on the seat of my pants. I really feel for you guys at elevation. You're missing out on a lot of fun lol.
