Hello all,
My buddy has a '95 Supra with a GM TH400, 3800 Stall, T88 turbo, fully built engine/ head, etc...
He's just got it off the dyno and is hitting around 708HP to the wheels, still not fully tuned, running lower boost (25psi) and not running his nitrous yet.
Issue: While @ the track, when trying to build boost, his car pegs @ 2000rpm and launches crappy.
His first run @ the track was a 15.?? @ 120mph.
He used a small 30-40 shot and got down to 14.3 @ 120mph.
This track is @ 5800ft above sea level and he running ET Streets and skinnies in the front. Full cage. Car does a hell of a burn out and then once he pulls to the line and tries to build boost he says it only gets him to 2000rpm and when he launches he gets a tiny bit of spin and it takes forever for his turbo to finally kick in @ 5500rpm.
If we take it on the street and start from 2nd gear (higher rpms) the car lights up the ET's and hauls booty.
Thinks it's an issue with the torque convertor. Would a transbrake help at all?
Thanks!
