how much psi on a modded 406?
well i planeed on running a 150 shot on my 406, but decided to go with an ATI procharger. the engine is forged bottom end, AFR 195 heads, ect.. 10.4:1 comp. but my main concern is how much psi i can get out of the s/c *with intercooler* . if im only going to make 150 hp on the s/c then ill just go back and get the NX kit. but if i can run like 8-9 psi on the engine and make alot more hp then ill be happy. BTW.. im guessing il have to get bigger injectors. 30# SVO's good enough?

And Darcom runs what psi?? What times does this get him?? None I know of. I then believe his car should be negated for discussion.

I'm going for 15 psi on my 412, but it is very modded now.
