slowcharger and pulleys
 

right now i run a 3.3" 6rib RR pulley on a P1sc .. i have a 2 core intercooler and a WMS boost pipe and i see around 13 PSI on average just after 6krpms.

on a freezing day ill see 14psi

i dont have belt slip except maybe just a little spec of dust flies onto the alternator here and then but just as normal cars would do. the clearance between the alternator and SC pulley are around 1/8" .

anyway, my question is do you think ill get a lot of slip with a 3.1 pulley? are you vortech guys running 3.1 without problems?

i plan on getting a 3.1 RR pulley and shooting for around 15-17psi

i know a guy running a 2.8 on his p1sc and not slipping... he makes 15psi and then his BOV leaks so hes working on that now..

ideas?

(i could always get a manual tensioner/ac delete from RR as well :) )

i get dust

what size belt? and how much boost

I have dust and I'm using a 108 belt, with a 3.4 pulley Dom I don't really think it will slip that bad.

I agree it shouldnt be that bad

i make 14 lbs now with a 3.3 NO belt slip except for minimal dust in the alternator pulley. i just ripped a consistant 11.6 car a new asshole so im happy for now

i spun a little on the launch, he didnt. i had a passenger, he didnt.. i beat him by 2 cars. both cars on slicks

I wonder after I get my motor built what pulley I should switch to. Would a 3.1 be to small if I'm already making 13 psi with a 3.4 thru a 3 core?

try it. if it doesnt work. sell it !

maybe a 8 rib to boot. I want to make atleast 15-20psi. I'll see how it turns out after I get my motor built. I'll take it to get tuned and then after awhile I'll swap. R u running the 6 rib right now?

i am on 6rib. i might send my p1 to get rebuilt to the d1. ill keep the same pulley size and should make 15-16 psi

how much power can 42lb injectors handle

I think they can handle about 550 to 600hp I'm not positive so don't qoute me. If you have a beefed up fuel system you could go bigger with 55's or 60's. I'll probably get the motor rebuilt first see how the tuning goes and work from their. Right now I need a new convertor so if you know of any good deals let me know. Or a differential.

there is a 3200 stall for sale in the classified section. also you can get a PI multidisk stallion convertor for a little over 600 bucks new. they have a military discount its about 10% percent off. i would of got it.

200 bucks ill give you an Auburn Pro 31 spine differential.

What did they fix on your diff, If I get that how long would it last? I don't take my car to the track that much anymore but will this thing last on the street for about a years+. Depending on If you have it and I can get some new axles.I will be able to deal when I get back in the area around the 20th of March. So try to hold onto it. I'll drive to meet you to pick it up when I get back home.

Also if I'm making 13psi with a 3.4 pulley if I switch to a 2.9 pulley wonder how much boost that will net me. Before I even consider putting the new pulley on my motor it will be forged!

a lot of boost...

the auburn was fine it was the bearings got toasted. so youd have to buy some bearings. the auburn pro is just fine it will last forever. jfitz used one for over 2 years running 10.6

How much is alot of boost I went from a 3.6 making 9 PSI to a 3.4 now I make 13 psi so maybe close to 20 psi LOL.

What bearings are you talking about? So is the Auburn still broken or something? Or the bearings for the axle's?
