T-rex and spray
I am up to a 250 shot now on the trex, no problems. Car is cam, valvetrain, intake, exhaust, longtubes, and bottle. My times are kind of irrelevant to you, since it is in an rx7, but as a t56, 4.10 rear with 2950 raceweight I was trapping 138 on about a 175 hit.
I have a heads and cam TREX car. Makes about 635rwhp on a 200 shot with a turbo 350 and 12 bolt. I upped the shot but it didnt really pick up much for some reason. Car runs 6.20's in the 1/8 like a bracket car
