Just having a debate among friends here. Has anyone ever tried a Performer X with a stock B18c1 with the simple bolt-ons? Air filter, header, cat back etc..Ditching the GSR butterflys on other manifold like the SK2 ITR design normally drops your mid range. My question is with the longer runners of the X can most of that be saved. Anyone ever do any dyno time?

 

I want to know this also... only dynos of the performer x i've seen are mild built engines..

 

to be honest its a waste of money , there are other bolt on's that will give you more power , example a header, bigger throttlebody, ect.... don't waste money on a intake manifold untill your engine needs it , with bigger cams, higher compression...

 

I will be running on one on my b18c1 but with PR3 pistons....with no cams but with headers and exhaust. It'll be next month until its done, have to send it out my block later today or tomorrow. I should be taking it to Chad on his CTR Dyno thereafter. After this, I will have Blox B's with supertech valvetrain. and another tuning session before and after.
