RJ MFG Supercharger kit Feeler...

I wouldn't expect any stages and pricing for several weeks. RJ MFG is working with laminova directly about the intercooler core. the design there isn't finalized and that will affect some of the other parts. I can say they are looking into mezeire (sp?) 55gpm pump that has a 3000+ hour pump life! That's a huge leap up from the bosch pumps stillen uses. Also after reviewing the cooling capacity I believe they have decided to stay twin pass on the heat exchanger.

The current idea is to run a 4" crank pulley and a blower pulley ranging from 4"-2.5" for stage one. Now the stage 2 guys I think they are bumping the crank pulley up to a 5"-6" crank pulley. So far I believe they are trying to limit the drive ratio to 2.0. At least for those looking to rev to 8.5k-9k. If you stick to lower revs you can get more of a drive ratio (2.4 if your stock rev limit).

It's definitely going to be interesting to see what they come up with. But if I had to guess I would guess that the price per hp will be competitive. The stillen kit is about $19/whp averaging 420whp on 8psi. The GTM/gamma kit is more expensive at $22/whp averaging 410whp on 8psi. This is based on their retail pricing. So if RJ MFG are able to make 450-500whp on 8psi they would be competitive pricing wise with what they have stated thus far.

I am stoked!
