The best time in the T with the TE44 turbo and the .63 Precision exhaust was 12.98 @ 103 mph (19 psi boost, 4 psi launch, race gas and Red's 100 octane chip). The car had turbo lag. I switched to the .63 Garrett housing (RA recommendation) and the lag went away. In hotter weather with the same chip, boost and launch the car went 12.76 @ 105.5 mph. 60' time dropped from 2.0 to 1.8. The Garrett housing looks much smaller than the Precision housing but seems to work better in this car. Does this performance make sense for a basically stock motor?
