Blower Cam Specs: Opinions? Ok, here's the cam I am going with, 04 M6 GTO:
235/242 on a 115 w/ .642/.612 lift
Pertinent Mods:
ATI P1SC Kit w/ fuel upgrades
Z06 MAF
N.W. 90mm TB with F.A.S.T. 90 intake
Kooks 1 7/8" LT's & catless mids
Questions:
-Suitable grind for a blower?
-Will good tuning allow for good drivability, or a lost cause?
-What kind of curve would you expect/anticipate?
Thanks in advance...

3.90s will help make up for the low end loss, but might not be enough. that's pretty big cam.
a more suitable grind, IMO, would be the vinci XXX cam

BS. itll lack a little down low but youll never tell. Youll likely float the valvesprings though with that intake lobe if its an LSK
WHat do you want it to do? Cant tell you if itll work good unless you tell usyou want torque instant like a nitrous car, do you want it all up top so you have achance at hooking etc?
Ive done blower cams on 111 LSA and does exactly what the customer wants, but have to know what that is

I have Patriot Dual Extreme springs, so that should take care of the spring float?
Yes, an LS1 04 GTO. These cars are difficult to obtain traction with off the line w/o slicks, but with higher power levels are also prone to break stubs and more;fully independent suspension.
I want a car that once I get traction can and will pull like a sumbi**h.

You dont need or evn want a silly aggressive intkae lobe on the blower, your not drawing in a intake charge, you pushing it in with a belt. Hard on parts unnecessarily.
A mild nitrous cam would work even if your looking for 4500-6500 for ex. something in the 225-232 range on the intake lobe and whatever lobe the exhaust system woudl need would do it fine. Id personally cam it to kill and the midrange torque as possible and help it breath at 7000. It may look peaky on the graph but if you cant use that extra 100 ft lbs on a street tire why have it.

I am not a cam geni but I can definelty say that is a big as cam! Especially for that application I wouldn't dream of it! I agree with the Fms 232/236.585/600 114lsa. That is the max I would go, I for myself would probably opt for even just a little smaller. Something like 228/232 .588/.588 114LSA or 115LSA, but thats just me, not saying thats the best of what you should do. Right now I am on the debate of getting a procharger and a blower cam as well

We normally use our G1 (228/232 .588 .575 115LSA) with blower setups, the cam has stock driving manners and really works well with stock cid procharger setups. I will be posting a graph of a G1 cammed, D1SC Procharged C6 that is making a hair under 700 at the wheels in the dyno section

Figured i'd update this thread. I love this cam!!! The big power comes on where I can use it on the street. No point in having everything down low in a car that can't stick it (even with BFG drag radials).

I'm running a 228/232 572/578 115lsa and its a nice cam. Power comes on @ 3,000-3,500 and screams all the way to the top. Also if you haven't bought the blower yet spend the extra $300 or so and upgrade to the D1. You'll want more power. Just look in the for sale section... lots of p1sc for sale most because they swaped the p1 for the d1. I'm running 10#'s of boost and there is alot left in the d1.

Looks like the D1 has more tq potential. I made 555/445 with the P1 @ 6PSI w/ 3.85" pulley. Same fuel setup as you, but with the KB BAP. Holds 65 PSI to redline.
Cam, FAST, NW TB, Kooks all help with volumetric efficiency. The real boost # would be closer to 11PSI without the breathing aids.
