I'm not sure who specializes in blower cams for the 3 valve (since i have a 2 valve) but i'm sure Comp Cams would be a good place to start.

I found a couple cams on summitracing.com. They are Comp Cams and they are built for supercharged 3V mustangs. Thanks again for bringing that to my attention. Like I said earlier, I completely forgot that they made cams for supercharged engines and I'm sure these cams will still have a good sound.

@Glassvapor. Don't mean to sound like an idiot, but as stated in my first post, I know little to nothing about superchargers so I have a question for you. Now, you stated that it is 5psi of boost at 2,000 rpm. Does that mean that the 2,000 rpm mark is where i will see the peak boost or will it get higher as the rpms get higher. I'm guessing it would go higher but do you have an idea of what the peak boost would be? Thanks!

Twin screw style blowers make almost full boost by 2000-2500 rpm. So if the kit is advertised to make 5 psi, it will basically make that from 2K to redline.

Okay is the E-Force not a twin screw blower then? Because TS blowers will usually make within 1 psi of it's maximum boost output from 2500 rpm on up.

Have you considered any of the Saleen offerings? Check out Brenspeed. I understand they are practically silent as well (no whine).

TVS is NOT a twinscrew. It has no internal compression at all. It is simply the most modern Roots with a hi-helix twist to the identical rotors. A twinscrew has non-identical rotors that turn at different rpms.

Just a thought for the original poster, with a twinscrew blower, you don't need to deal with cam swaps. With all your power coming on at WOT, there's really not much to be gained with cams. If you were building an all-out race car, then it might be worth the hassles, but with a street/strip car, on a stock bottom end, not so much.
