    Cam + Fast LSX/90mm

    What kind of rwhp could I expect with a mild cam/ FASTlsx intake and 90m TB.

    I currently have ARH 1 3/4" LTs,ORY, CAI and Magnamouth exhaust. 338rwhp currently on my 99 T/A M6

    Also, anyone with a similar setup have any cam reccomendations?

    I have pretty much the same setup. Hooker LT's (same size as yours), no cats, no A/C, no air pump to heat up the cats, no EGR, have a custom Y-pipe and magnaflow catback exhaust. I have the 85mm BBK intake with the stock TB, and a compcams cam (222/224)...I recommend you go bigger than that, and I have 386RWHP @ 6200 RPM and 373ft-lbs @4500 RPM. You should have more than me. When you swap out the cam I also recommend getting better pushrods (if you havent already), and LS7 roller lifters, that way you can raise the redline to 6500-7000RPM. I have mine set at 7000RPM, but the valves start to float at 6500RPM (but thats due to a stock valvetrain and heads). I hope this gives you a better idea. I would say that you would be close to 400RWHP with a good tune.

    I got all of my parts from ws6store.com. You should check them out. They have everything that you need.

    With headers, exhasut, a lid i made 337rwhp, you beat me by 1 hp, i have a 228/232 .585/.595 112lsa cam and lsx intake manifold sitting in my closet. Also new springs, pushrods, timing chain, im just waiting on my oil pump and gaskets and i will be puttign all that on including a new cltuch, but im thinking 390-410rwhp with a tune. It doesnt make any sense to put you redline at 7000rpms, if you loose power after 6400 and you valve float at 6500.

    ah no, wit ha 228/232 cam most poeple gain 40-50rwhp from the cam alone, with the lsx intake manifold thats good for another 15rwhp. With good bolt ons and a tune you could see a 50-70rwhp gain, depending on cam.

    You should do that when you get the set of heads that you want, that way you can portmatch them.

    As far as a cam goes, I went with comp, and havent had any problems. Apparently they have a program out now where you can see the results of putting a cam in it. I have only heard about it. But the tech's there can easily help you with a cam that you would want. Just email them, and they will get back to you within a week.

    When I get the set of heads that I want, then the valves wont float anymore. I set it there without knowing that they would float. I didnt really want to go back and have it changed again.

    Here's a pic of my dyno sheet...like I said before its a pretty mild compcams 222/224 cam.
