Procharger help needed
Wondering which procharger pulley i should be running to hit around 20psi and make 800 hp at the flywheel & 640 rwhp.
The motor is 357ci - 200cc canfield aluminum heads, large solid roller cam, F1 procharger, victor jr intake, 1 5/8 headers w/ 2 1/2 inch flowmaster exaust.I currently have a 5inch blower pulley and it dynod w/o an intercooler or meth about 500rwhp and 498 rwtq. This year i have installed a Large FMIC and need advice on which pulley to buy. Also, does anyone a 12 rib pulley for sale?

It would only be a guess for anyone to suggest a pulley size. I would calculate your current blower speed, the formula is on ATI's website. You need to know what size your crank pulley is, along with your current 5" blower pulley. The F1 is good for 70,000 rpm. I'd start out by figuring what pulley would be required for spinning the blower an extra 4000 rpm. You first have to make up for the addition of your intercooler, so you may have to experiment. Bob

You'll need that boost to make 850-900rwhp maybe. Depends on the rest of the motor though.
