Dynoed the GTX3788AVNT today..640whp.

[bastarddsm]

So I've been tinkering with a Garret AVNT off a big isuzu staight 6 on my talon. I've had it running pretty well and today was my birthday, so the old lady took me to get the shitbox dynoed. Not much for AWD dyno's around so I was stuck on a 2wd Dynojet 248H. Can't say I was very impressed with the whole experience. Tach pickup was boned so I didn't get any RPM data, didnt get a print out or even an email of the run files. Car ran good, but just blew off the tires once the boost hit.

Anyway In high gear this thing will hit 40psi at about 4300RPM, and only has 25psi of drive pressure. I think there more to be gained in a nicer header, and a more tuning on the vanes. In 3rd gear it's been 40psi by 5000. It's not a super quick spool, but it is a GT37 . I think with more time this thing could defiantly mop the floor with a twin scroll setup.

I think there is power left in timing and opening up the vanes a bit more on the big end. Was right around 50psi of drive pressure at 8000 with 40psi boost. Between the last two pulls it picked up almost 50whp from 1* of timing . Looks like it was moving right about 64lbs/min at 8000 and 40psi.
