Three cheers for Brent

Everything else is done now. Now trying to revive my frozen hands and butt. finished when it was about 27 degrees outside. Its supposed to be colder but I guess I got lucky.

Hopefully we can see how the car runs and shifts tomorrow. There will probably be a little TD streetracing action up north this weekend and I want to take my car. Some TD's maybe a dsm, turbo vw and maybe a stealth TT, srt-4. Hopefully it works out and we have some video.

Went for a scary ride. 2 4th gear pulls.

#1 pull it was way to lean and boost was creeping badly. 3000 rpms and we were at full boost 5 psi. boost then crept up to 9+ psi near redline and the car leaned out to 15:1 a/f. EGT's got up to 1725. Not good. Glad I had a datalog of that. Cranked up the rising rate regulator.

#2 pull 3000rpms = 5psi. Creeps to 6ish psi and then above 4800 rpms it creeps up to 8-9psi. My guess is the engine really is moving air at those rpms and the tial 38mm is not able to handle it. Only leaned out to 13:1 but that was a blip it was more like 12.7:1. Added a little bit more fuel.

This is with the custom intake manifold fixed and cams advanced 4 degrees.

So my question is this. When if turn the boost up, is it going to creep even higher or will it probably creep to the same numbers as before?
I dont want to turn it up to 8-9 psi and then have it creep to 13-14 cause I dont have enough fuel for that.

Wondering this question because if its going to be a POS and creep that high, then I might as well run the same boost number throughout the RPM range so tuning the a/f is a bit less weird.

Is my camshaft timing complicating boost creep or shouldnt that be a non issue above 4800 rpms where the creep gets really bad?

One thing I am going to try is giving a dedicated vacuum line to the wastegate as its currently sharing with a lot of other stuff.

[Ondonti]

On an interesting note.
Car does 40-120 in about 13 seconds on my datalog.
Thats all in 4th gear starting at 2000 rpms. wee. Previously it took about 12 seconds to go 40-100.

Very good news indeed. I hope everything works out well for you Brent.

I sure would like to see a video of this momentous event.

[Ondonti]

going to have to fix some things. I didnt write about getting stuck after my 2nd 4th gear pull. Might do that tonight. Lets just say I had the powerwire to my wideband short out and blow a fusible link and I got home by twisting the fusible link back together after snipping the shorted wire.

Brent you should write a book about this project. No wait. You already have really. It's is one helluva fascinating saga too. I can't wait for the made for TV movie!

OMG you really created a monster there Brent. I love it. Just love it! Oh man that should shut up the 3.0 dissers. Omg that's so cool.

It's a total rocketship!

Tons of crazy stuff at the end.
