C U IN REARVEIW

Anyone running this setup? Any slipping issues?


*****EDIT....3.4" PULLEY*****

I literally just got my 3.4 in the mail yesterday. I have the summit c2501 balancer, but i know i was getting some slip with the 3.6 because it would leave rubber lines on the mounting bracket that were inline with the belt. i have a feeling I'm going to have some slippage i am going to tighten that tensioner down

I know there are a bunch of people running this setup....?

3.4" 6- rib will be fine if setup properly.

what exactly needs to be done to set it up correctly?

JetstreamGS

Just ensure its aligned perfectly.

i know it seems like an obvious point, but make sure you get the right belt size from a&a as well

I run a 3.4 on my v3-t and I don't notice much if any slip... If I run it clear to 6600rpm I'm at 11-12 lbs... I usually shift at 5k or sooner when dailying, which is about 3lbs at 5k...

Soon to be swapping to a 3.125 that has some kind of coating on the pulley so that it doesn't slip...

if your getting 3lbs at 5k your slipping big, did you mean 8 lbs at 5k? That's cool about the anti slip coating who does it?

It is alignment, but also proper belt, proper tension, and making sure everything is working. Just takes one piece off to mess everything up. Tension is one of the biggest things that is overlooked.

With a 530 belt I see 19-20psi, but with a 525 I see 23-24psi. Because it is that much shorter, that allows more tension, and if you run out of autotensioner as the belt stretches, it will slip like crazy.

Maybe it is slipping, but I just assumed that because I have a stage 3 blower cam that having somewhat low boost until 5k+ rpm was normal... I live at 4600' elevation and still see 11-12lbs at 6600 rpm, so I figured I must not be slipping too much...

I believe the coated anti-slip pulley is from 928 motorsports...

Normally you'll see half of max boost at 2/3 max RPM on centri setups

i.e. if you see 12psi at 6600 then you'd expect to see around 6psi at 4400
