wow that was a good read
Not as much as some people would have you believe.BMAC96GT said:Does it matter that the square ports of a PI intake won't line up to the oval ports of NPI heads?
I have a question.. I was wondering with all the PI swap info out there and guys saying that they got PI sawp parts cheap.. Is it really worth doing vs just paying alittle more and getting Aftermarket HCI.. can u really find dirt cheap PI sawp parts that work.. So far when I look for parts around my area.. they are alot of supposed to be's and hiped up junk that I would never trust running.. Can we break this down.. PI sawp Vs Aftermarket HCI.. also it would be good to factor in the parts needing machine work.. as I dont trust too many out there.. Thanks for u time.. hope I have said everything clear.. but just would like to know..
Another thread I've read indicated 15-18 more HP with just an intake swap. It then indicated about the same gain from a cam swap and retaining the NPI heads. All of this documented by a dyno, of course.
30-50 hp from PI cams and intake alone ...i VERY much DOUBT IT...awhile back i did those 2 in combination and it shur didnt feel even 20hp faster...it just once again helped in the upper rpm band..but once i put on the heads PI ( were ported hough) wholly shit it woke up the car...woke it up so much i blew all the old shit i should replaced when doing the swap...hehe now im 32V
The cams alone result in a 13 – 16 RWHP gain and the intake results in a 15 -18 RWHP gain.
svtcobra347Good article! I did the "Half PI" swap on my wife's 96 GT 'vert. Before dyno was 195 RWHP, after was 226 RWHP. Couldn't be happier because I got the cams on Ebay from DSS Racing (new take-offs, never run) for $11.00 shipped, the intake was free, and the gaskets were less than $50.00. 31 RWHP for less than $60.00 can't be beat!!!
