Maf location, iats and heat issues.

there's been multiple engines that went just N/A 100% stock.

some just go boom lol

Sasha from BP is building me a Air/Air, Were keeping the stillen manifold, Getting rid of all the air/water stuff. Rotating the blower 90 degrees down, pipe down to intercooler on driver side, then a y pipe out of intercooler, into 2 pipes up to the stillen manifold, and mafs will be mounted right before the TB's

What is a TB?
Are you going to use UpRev maf?

EVOHUNTER 04-30-2015 06:12 PM

TB = Throttle body

Nope, factory Mafs will work fine with my setup, 10-12 PSI.

Once there back in the factory spot they have a lot more range.

I dont youll need the uprev mafs, could be wrong tho.

Whats the rating on the Tranny, my god that thing probably holds a lot of torque huh?

Have Sasha go ahead and make a jig for that. He can call it the stillen FMIC upgrade.

Keep us posted on this for sure. Definitely interested on how well the Stillen charger can perform if you eliminate some of the short comings of the kit.

The MT, who knows. I don't recall anyone breaking one. The most power I've seen on here is 700+wtq.

The AT, about 375-400wtq. The discs in the upper gears just can't handle the power.

800whp / 800lbs ft
That's there entry level upgrade

- Level 10 upgraded 7AT Transmission (Hamburg, NJ)
- ART Test Pipes
- Stillen Headers
- CJ Motorsports v1 Fuel Pump (on its way)
- 750cc Injector Dynamics

First off talking to Stillen is tough, and talking to Vortech about superchargers and the kit that its on is pretty rough as well. Vortech was much easier but still very unwilling to help since its the Stillen kit.

What i would like to accomplish is max out the Vortech V-3 SCi supercharger that is currently on my car. What size pulley can i go to and achieve approx. 16lbs of boost? The supercharger is rated to 17lbs boost. The other question i have. Is there anyway to upgrade to a Vortech TI? I have been told that the bolt pattern is the same and should mount up but i was wondering if anyone has any experience with this type of upgrade?

That is pretty close to what JTran did with my kit. Upped the S/C rpms with a 34T-30T cog setup on the backside of the blower. I don't remember the exact numbers, but it was spinning the blower around 56,000 rpms. I saw 13 psi regularly and the car held up fine. Next, I swapped to the SI impeller like AMNVQ did and saw around 15-16 psi. That ended the stock motor. We rebuilt and went with a Single Turbo instead of modding the Stillen kit any further.

-It's a good idea to swap back to the stock IM and MAF placement. Build your charge pipes large enough ID to keep your stock MAFs from maxing out (you are going to have to flow a lot more air than the turbo guys to make the same power due to parasitic losses).
-Find a good way to brace the Stillen S/C bracket (it will flex at those power levels and cause belt slip).
-ATI makes an oversized-dampened crank-pulley for our cars that would be perfect for increasing S/C rpms, but it's really expensive (6.5" OD if I remember).
-Check out VSRs intercooler/charge-pipe setup on their Single Turbo, a mirror image of their setup should work good with the Stillen S/C. Single in/Dual out with the inlet on the top-passenger side.
-Talk to Phunk about what your fuel needs will be for 550 whp on a S/C VHR.

I hope some of that helps. Good luck man.

To add to this.

Most Turbo cars making 600 on the stock motor reliably are running E85. Is that true?

Parasitic losses to spinning the S/C. I have read more than once that it takes up to 80 hp to spin a Vortec S/C. I know it will have a lot of variables, but it's a good number to think about, that puts a 450 whp S/C cars' engine feeling the same stress as a 530 whp turbo car. Am I wrong on that assumption?

Somewhat. turbo setups induce higher pumping losses and have to deal with egt's that a supercharged engine never will.
