K, I'm assuming that my current underdrive crank pulley should go back to stock when I supercharge? Cause it will underdrive my SC also right? And since I have a Dseries Unorthodox doesn't make a Rc version for me. Dang. Am I right though?

Holden

Yes. The underdrive pulley has to go. I had a UO underdrive pulley that I sold after installing the JRSC. Go back to stock.

Now I have a CRV crank pulley and overdrive the alternator. (and blower).

My site will probably never get an update. I'm not into it anymore.

Thanks anyway.

I have the Crv crank and want another 1-2 psi, is there a way to do this with out changing the blower pulley?

Hey, 1strdtko. If your jrsc runs off a double pulley on the alternator then you can use a step pulley. It will keep you from overdriving you alternator, but it will probably give you more than 1-2 more psi. Contact larry@endyneracingengines.com and Jim at wheelking@webtv.net. They have both been very helpful with my questions on step pulleys.

I'm not into the site. My car is pretty much fully developed. Now I spend my money on tires and track time.

1strdtko: Combining a CRV pulley with a stepper pulley will provide 15psi or so, which is beyond what the block will take for long and is beyond the abilities of the blower. You'll get 8 seconds of awesome power, then everything will be 300 degrees and power will suck for minutes untill all the metal cools down. Either pay for more accurate tuning or go turbo if you still need more power.
