Showed a buddy of mine what dr750s do at 6psi, which is absolutely nothing.

yep, pulls clean now 18 PSI, ngk 4091 (R5671A-7) gapped to .025.
If anyone wants a set of those champion plugs with 3 miles on them let me know.
Also, at 18 PSI accidentally got up to about 12.5 AFR, no damage, but definitely adding some fuel there. Car wants a lot of fuel in the 3500-4500 range for some reason.

Nice John. Show off the car well
I installed a new set of cams...

Today I drilled the wastegate actuator rod to run the cotter pin through..4 drill bits, 5 hours later...Also screamed innumerable profanities at it. Have the motor hoisted over the engine bay now, that's as far as I got before my back gave out for the day. With any luck tomorrow or Saturday I'll hook up most of it and get the motor installed, have this rebuild done by Monday I hope..Only been off the road for almost 18 months.
Sounds like my latests adventure.Quote:

Going to press the ball joint and put the new Hub YAY for me , I hope after this I have no vibrations :/
I bought some fancy parts for it.
I bet a lot of stories start this way...
So I was raising the boost.. on my hallman and before I was only running 18 psi. Well the instructions say to try .5 to 1 turn at a time and well, "ain't nobody got time for dat", right? So, I went 3 turns thinking that would get me to about 21.
I was giving a co-working a ride this morning and hammered it in 1st and it shot up and hit the rev limiting so hard I must've fouled a plug. It ran rough for about a minute and smoothed out.
So, at lunch I thought I better go do a 2nd gear pull to be sure the motor isn't hurt. It takes off absolutely like a bat out of hell and pulls clean. I did another run and tried to watch the boost gauge and it went up to 25 PSI and settled around 24 or so.
I checked the logs and afr's are great with no knock. I was going to go a little slower up to this much boost, but I guess I'm already there.
I hit 193 peak load on my 427AWHP virtual dyno and today hit 259 and this is only in 2nd. This turbos spool so fast it doesn't seem to make a difference, so it is great to get the tune close just using 2nd.
A rolling start in 2nd feels like a huge launch used to.
You know what I like most about the flash ecu? If your tune is solid, it doesn't really move just because you are running a lot more load. I was running mid to high 11s at 18 psi and it is the same now.
Plenum, throttlebody are in
Finally made the rear oil return clear the axle. That's a huge relief.
Now to get this downpipe to line up properly and I should be good :)
Sounds a lot like Chris Hill's 32 psi boom run in SLT back in the day, only he wasn't so lucky, hence the boom.Quote:

Sent from the garage
I feel like a schlub saying this... I havent drove it since last Monday. I got my little ranger for a DD and the 3000 hasnt moved!! I got new insurance for it and put the ID card in the glove box..
Our cars smell awesome when left sitting still for a week.
Glad mines not the only one lol.Quote:

Lol. I remember doing that with my Hallman. I was at around 20-21 psi and decided I was going to turn it up some more so I cranked it a few times. Well, I must have loaded it up pretty good in 2nd or 3rd because I peaked 31.6 psi. Haha. It scared me because I wasn't expecting it but more so because I thought for sure that much power on my stock motor would have busted a 2nd gen piston ring land. Everything was good though and I turned it down to 26-27 psi right away. I never really went past 30 since then but going from 20 to 30 psi is a huge leap in power. It's really fun when you get to turn it up.Quote:

Think this makes me #25 or so on the 6g74 tt swap :p
Are you having clearence issues with the rear portion of the front subframe and your downpipe. thats where i had issues. I want to make a precat delete pipe that comes down further and turns to the back of the car and connects to the downpipe via vband.... maybe make the front portion of the downpipe and the rest of it all 1 piece.
Sounds a lot like the way I ended up tuning. I was thinking small increments, but ended up jumping from 12psi to 16psi with no problems. Went up small from there.Quote:

How is 3rd gear? I've noticed the higher the gear, the more prone to knocking it is (then again, you'll probably never have knock on e85).
Until today I had never seen any knock, but I do get 1-2 counts here and there now, nothing I'm too concerned about. Biggest problem today is I had to dial back the boost or I had spark blowout. I'm really not sure what to do with the ignition system at this point, but I guess I'll gap down to .020, but that shouldn't be necessary. I wonder if my HKS DLI is dead.Quote:

http://www.chrisbehnken.com/Images/p...0wNZW_Ke3p.jpg
Pretty close to where I need to be. If I can get the ignition to deal with 3-4 more psi I should be okay.
oh and for those wondering about the consistency of the virtual dyno software:

After the 480 run I turned the boost controller up .25 turns (different stretches of road).
Finally got the front turbo removed and drivers side half shaft off. Reassembly tomorrow.
Old 9b has Zero shaft play, in any direction. I'm replacing it as I suspect it is the cause of burning oil. I hope I'm right.
You should make a thread like mine "tuning on dr750s". Would make for good info for everyone! Interested in looking at your timing map too.Quote:

New clutch feels nice. No more chatter.
I also apparently did a much better job at bleeding the clutch this time. Nice and tight :)
Finally got around to replacing my clutch line with a replacement from Ninja Performance. Glad to be back in my VR4 instead of my 87 F250 (60 mph top speed) I've been driving the last two weeks.
