mine is not dynoed yet but in saying that, croyden think it will crack 650rwhp on about 22 to 24 psi, in a s15
also i know how much u made, i even envy you mates, r32gts with his dyno sheet, thats a fat curve and would be a weapon to drive no doubt.. i wanted to go t04z for that reason, but croydon said to go for the 4088r setup as its more of a modern turbocharger....
i know they make the power but the 4088r is slightly better, im not 100% sure but i trust croydon has thier reasons...
