Tim brought us a stone stock '08 GT 500 to have a supercharger put on with the only exsisting mod being axle back mufflers We decided on the new Vortech/Lyscholm 3.3 twin screw supercharger. When doing GT 500 aftermarket blower cars they are usually installed with a set of headers. We were slightly disappointed in the power numbers with 640 RWHP at 19#.


The customer brought it back under our recomendation for a performance exhaust. We installed Kooks 1 7/8" headers, 3" catted mid-pipe and the exsisting FRPP mufflers. We threw her back on the dyno and saw the RWHP numbers jump up to 707 RWHP, which is an increase of 58 RWHP and 42 RWTQ!

Check out the video and pics of Tim's amazing ride!

Very nice numbers with those mods!!

05 Mustang

very nice!

Cobra Drifter

Cool, but the video says 717 or is 707 SAE?

mystichris@MD

The graph actually spiked about 10 RWHP at the end of the pull; I guess the video guy didn't catch that.


Yes they are, wish it was my car though.

When did Vortech start making Roots-type superchargers?? I've been out of the loop a while, apparently! Sorry if it's a centrifugal in the video, I can't see it since it's blocked by the proxy.

This past summer the first ones were released for the '03 Cobra and GT 500. You are right it is a twin screw and not a centrifugal; the rotors are made by Lyscholm.

Isn't Lyscholm the same company that makes Whipple's scrolls? I know they used to do the Mercedes AMG ones.

They did make them for Whipple, but they don't anymore and that's why they hooked up with Vortech.
