I had to run a drain line from my Whipple to the fuel tank, because my blower is so efficient that it actually makes gasoline.

I got a buddy that gets his terminator mustang tuned here. He says his guy does gm too. If you are interested, shoot me a pm. (as a side note, my friends svt puts down over 650 at the wheels at our elevation with no meth, just boost.)

Truck is stock other than 20's and a cat-back. (RCSB, 5.3, 2wd, G80 and 3.73s)

Unfortunately I wasn't provided with a dyno sheet so I don't have the curve and can't remember the torque peak.


Thanks for the info guys. I'm looking forward to getting a tune and hopefully a pulley. Not a lot of pulley options. I do know that the 2005 - 2009 Saleen Stangs use the same compressor, but the pulley's offset is off by about a half of an inch.

If you want pulley options I bet Jim at Reichard Racing would be happy to whip out some for you, He makes top notch stuff.

im wondering how small you can go on it. if its a 4.0 pulley and puts on a 3.0 it should gain him like 10 psi boost

They make a 2.8 for the Saleen Stangs. Smaller than that I think you run into problems clearing the hub on the compressor. I really think a 3.5" would put me where I want to be. That would be drive the compressor about 15% faster and hopefully keep me under 10 lbs of boost.

I'll have to look up Reichard Racing. I don't think there is an off the shelf pulley yet.

Thanks.

He's a small machine shop and will do some custom stuff by request, I had his Ultra Grip series on my last setup and loved it... Very similar to Leftcoast 32's RIP pulleys.
