If you're going to go to the trouble of swapping heads on a non-PI SOHC car, why would you NOT swap to trick-flow heads?
Im not swaping heads on anything. I was just wondering really if a supercharged non PI car would be worth buying. Im looking at a procharged one and kinda wondered what it would be capable of with non pi heads.If you're going to go to the trouble of swapping heads on a non-PI SOHC car, why would you NOT swap to trick-flow heads?
What kind of time's are you getting out of it?Most of the power is in the cams and intake.
Im running a novi with pi intake and cams on my 96.
Thats another thing I was wondering is if it would actually make decent power or not. Probably wouldn't do very good against a cam only ls1 though would it?Just put the Paxton on this week, getting it tuned saturday should be around 400 rwhp
No shit? That bad huh. I was thinking it would be close to at least 350 but I just found out it has stock manifolds too. Ouch. Its also running an fmu, thats a bad way at getting a good fuel ratio isnt it?I had a 96 and at one point thought about a blower. However I soon realized that with a blower and NPI heads my shit would only be at about 300rwhp. Do the head swap.
x2. Non-PI cars run like ass.Yes, they do make that big of a difference.
No bolt on-s?I had a 97 that the motor was stock on. I had a NOVI 1000 on it, made 12 psi at 6500 rpm and a safe pump gas tune made 330 rwhp(@400 crank hp). I had 4.30 gears w\ 5 speed and on street tires ran 8.12 in the 1\8th with a 1.90 60 ft. If I understand correct the pi swap will put the compression up pretty high as the non pi motors run a more compression height on the piston and a larger combustion chamber where as the pi heads have a small combustion chamber and dish style pistons. The pi's do flow a lot better than the non pi's also.
I had the novi 1000, x-pipe and catback. The motor was stock other than injectors. I ran an in-tank 255lph walbro. I'd say it was a nice increase over the est 215 crank horse they were said to produce. In theory for every 1 bar or @14.8 psi or boost you can double the hp of the engine.No bolt on-s?
