I'm trying to get some info on a twin screw puffer. I know Techco makes one for our CSRT8s, but who else?? It doesn't look like Whipple, Kenne Belle, etc does... Plus, any HP and TQ numbers coming out of the Techco camp yet??
Techco is still in the R&D phase, but they have posted some working HP numbers in their section. Also, RDP offers a Roots blower (Harop) (actually, they are having one hell of a sale right now), and PPP offers a Whipple package.
SMS (Steve M Saleen) has Twin Screw superchargers for the 5.7 and 6.1 liter. They are pretty pricey...
