thanx for the reply. but how did it feel on normal driving? did you notice the extra punch over the just the pi manifold? was there much difference down below? was there much difference up top?Mac-man said:i put on the pi intake by iutself at first..and it made a really big difference in the way my car ran...but the power just wasnt there at the higher rpm's of third and in fourth gear where yu really need it. when i put on my pi heads and cams later on about a few months later..i didnt notice a difference through first or second gear(probably because i was spinning so bad)...but when i got out on the highway and really opened it up through all the gears u coulddefinately tell that there was some extra power, like i said in third and fourth gear, because 1st and 2nd go by way to fast to really notice. so i would say thta it basically feels the same as just the pi intake alone, until u hit the higher gears..
yah that will be interesting, i bet you will dyno around 235-240rwhp which is great for not having pi heads. im getting my car dyno tuned in two weeks and ill let you guys know what happens. my dyno is in my sig minus the plenum/tb. after the tune with these parts on i expect to see 265-270rwhp/305-310rwtq.LI98GTStang said:I don't have PI heads to compare to, but I do have a PI intake and PI cams combo in my NPI headed stang. I put on the PI cams first and recently added the PI intake for improved reliability and better performance and really like the way the car is performing now. The power doesn't fall off like it did pre PI parts.
Here are my estimates as I have yet to get re-dyno'd post PI intake (I do have post PI cams though in sig): I hope this is not ricer math, although my sotp says it is not too far off.
PI intake +15rwhp
PI cams +10rwhp
total 25rwhp
PI heads (non-ported and no LTs or shortys added) includes PI heads, PI intake and PI cams +35-40rwhp
So comparing just the NPI heads with PI intake to the PI heads/cams/intake, you would be seeing a 20-25 rwhp gain. Not bad, but you also have to also factor in the increased compression that adds some of the hp and would require putting in premium gas. I'm anxious to see how my combo fares in the dyno compared to what PI headswap people are seeing.

I have the PI Intake alone with adapter plates and will be getting it tuned and on the Dyno tomorrow night. I'm really excited to see what the intake alone nets. My other mods are in my sig, so let's see how it runs on the dyno with a bump in timing. I'll post numbers either tomorrow night or Thursday.
Since I don't have the PI BOLT ON's (have PI Press On) I'm very hesitant to attempt the install. Had I known all this "bolt on press on" stuff before, I would have made a smarter cam purchase. As soon as I find someone to buy these cams I'm going to buy some bolt on cams.LI98GTStang said:Good luck and why aren't the PI cams in?
I'm pretty sure I know where you are going with this one Ry. Just get the heads, but get them P&P. I'm sure you'll notice a big differance. I do understand your desire to see numbers though. I want numbers on every mod before I do it to see if it's worth it.fstnfuriusgirl said:<---rysred
but is there anyone who did the headswap after the pi intake and where did you feel ur difference?
