[QUOTE="genesmob, post: 16249570, member: 126984"] I have a jdm 1500 long block with ss cams (love it) With a 15pct lower and a 4” upper it makes around 19-20psi in warm weather, Iat2 stays very cool with a triple pass he and a 14’he pump. With a 3.75 pulley it’s 21-22psi and around 1000whp (auto loses over 50whp compared to stick) with 16.5 deg on pump e85. Under 9.2se@152 in the quarter in a full wt convertible so far. I’ve dynoed with smaller pulleys and the 4.0 isn’t done yet. Sent from my iPhone using Tapatalk [/QUOTE]
