Default 355CI setup with blower
I have the 355 LT1 on the stand finishing up the last little bit before the install. I have the P600B in the closet I will install next summer. I'm in the military and currently station in Hawaii the worst state to have hot rods. I want the best out of the engine NA for now. Mods 355 bored and honed, forged eagle H beams rods and pistons, GM stock crank, cr 10.5:1, lunati Cam: Duration (Int/Exh): 282/290, Duration @ .050 (Int/Exh): 231/239, Gross Valve Lift(Int/Exh): .535/.550 LSA/ICL: 110/106, heads milled and mild porting, comp cam magnum 1.6rr, Holley 58 mm tb, pacesetters LT headers, Arp throughout. Does anyone think my setup will be suitable for the p600b? And if not what should I plan on doing before I put the procharger on; I.e. Cam change? Or will I be fine and put down decent numbers?

The blower will have to be spun harder to compensate for the cam, but it will work just fine. I'd use it the way you have it set up. Bob

You'll have to run it towards it's max impeller speed rating, which is 60,000 rpm.

To determine the impeller speed, the following formula is used:

Maximum impeller speed = crankshaft pulley diameter (N1) divided by supercharger pulley diameter (N2),multiplied by the step-up ratio (3.05 for the P600B), multiplied by engine rpm at redline. Bob

I'd use 60lb injectors. Methanol injection will drop the inlet air temps, I recommend it. Bob
