3.2 p1sc pulley questions

[04torchedpony]

Looking into getting a 3.2 pulley for my p1. Will that small of a pulley have belt slip? I have a thump RRR tensioner. How much boost will I see? And will it overspin the head unit?

yes, you will likely have belt slip issues. Might be better off buying a 10% OD crank pulley (go ahead and get an 8rib for later down the road..you can run a 6rib belt on it)

heres a blower rpm calculator

youll have to look up the max impeller speed for that blower, i dont know it off hand

I dont know why you guys are experiencing belt slip. I have installed many 3.2 pulleys on Marauders and no problems/slip WHATSOEVER!!!

are these marauders turning 7k rpm (serious question..i know some of the mach guys with autos crank up the rev limiter, didnt know if these guys were too)? could be part of why they arent

i think he is looking at the pulley i'm selling and with it being a Reichard racing ultra grip pulley and him already having the thump tensioner i don't see belt slip as a problem, i don't have the problem any more since i put the ultra grip pulley on and the thump tensioner and i'm only running 6 rib

I never run my car past 6200 rpm Anyway (5spd). It's stock heads stock intake car. I'm just wanting enough to hopefully see 600 on the Dyno

[DSG2003Mach1]

the RR pulley should make a huge difference!

i looked into an RR pulley but they cant bother to answer their phone or an email so to hell with em

600 with a P1 seems a little iffy imho, running E85?

with p1 i don't see you hitting the 600 mark, on a d1 its close on a loaded dyno i was at 554rwhp and on a dyno jet would have been close to 600

would the mach's use the same size belt as a marauders do? with a 3.2 pulley

What were the mods done to your car? Mines a 5.0 w 10-1 compression, the blocks been decked, header back bassani, 98 cobra cams and I'll prob have the intake ported later. Before I blew the car I'm pretty sure I was making 480+ on the stock motor at 10lbs. They guy I bought the kit from made 475/440 on the same set up I had and mine ran a lot better than his. But we'll see, Mid 5's would be alright but I might have to go w the d1 sooner than I thought
