procharger and cam choice?
procharger and cam choice? im putting a p1sc with a front mount and meth on my 99 SS and i already have a futral fm14 cam in it that specs out at 232 234 duration .598 .601 lift on a 112 lsa. my question is: am i leaving a lot of power on the table if i leave this cam in versus putting in a blower specific cam (ie EPP blower cam or some other custom grind)?
have any of you been in the same situation and what was your outcome?
im sure there is some additional power to be made with a blower specific cam but how much and is it worth the expense.
my goal is to get at least 550 rwhp and i already have ported heads with bigger valves, fast 90mm, nw 90mm, ewp, lt's, no cats, 4" exhaust, pulley, 12 bolt with 3.73's, spec clutch, 60 lb injectors, arp rod bolts, steel drive shaft, lightened flywheel.
will i need the cam to get me to my goal?

you should be able to reach that goal or close to it
i watched a guy put 510 to the wheels on 10psi throught his p1sc on a stock engine
stock rods and pistons?
fuel system?
a blower specific cam will usually net you some decent gains but it differs with every cam so without a back to back dyno youll never know how much

You should be able to meet your goals. You could sell the N/A cam and pick up a used blower cam pretty cheap. Bobs EPP cam is 389 or so. Either way you'll be close to your goals. I just like planning for the future lol. You'll want to turn the wick up after awhile lol

thanks for the input guys. i was hoping to keep the cam in there since it has less then 200 miles on it since it was installed. that saves me more money for the paint job lol.

Verdad Gallardo how much boost would i lose because of the little overlap (232 234)?
would it be in my benefit to run a pulley setup that would normally give 11 to 12 lbs of boost with the expectation that i would bleed off some boost through the open valve and still end up with around 10 lbs of boost?

How much boost the blower can produce depends on many variables.
* Cubic inch. The larger the engine the less boost it will make with a supercharger.
* Headers and exhaust. A better flowing system will produce less boost, requires a smaller pulley to regain the loss in boost. Ultimately though, more power will be gained.
* Camshaft and heads. A camshaft with some overlap will leak out some boost through the valves. Better flowing heads react a lot like a better flowing exhaust system.
* Altitude. Elevation plays a big part in how much boost is produced. Those people living in the higher elevations have to spin the blower harder to see boost.
* Condition of engine. An engine with real good sealing rings will ultimately produce more boost than one with worn rings.
* Rpm. An engine that is spun up higher in the rpm range will normally produce more boost.
