Damn blowers and their belts! I'm tuning up a guy's procharged truck and want to know how small I can go on the blower pulley before the 6 rib starts slipping. From my reading it looks like the 3.6-3.7 range seems to be the limit. The truck has a 408 with a D1SC and with the 3.85 pulley on it now its making about 8psi at 6000rpm.

Also if anyone has pulleys to sell, let me know

 

OD balancer?

 

Stock balancer. I actually just got a call from the guy and he is not opposed to swapping to an 8 rib setup, so I think we'll take that route. Now...anybody have any 8 rib kits for sale?

 

If he does stay 6 rib - a Reichard pulley is the way to go.

 

^^^ what he said i have a 3.5 rr pulley no signs of belt slip what so ever.

 

Anyone know how to get ahold of those guys? Or a supplier for their pulleys? I've been looking for one myself.

 

one of those pulleys is the way to go 6 or 8 rib........good luck getting one

 

Ok, so he seems to be on board for the Innovators West 8 rib upgrade kit. Are the RR pulleys just hard to find these days?

 

Man, I haven't really tried to get one now for a couple years. But last time I did, it was near impossible to get them on the phone. I think they stay busy with military contracts or some ****. Give them a call, you may have some luck.

 

^^Agreed!! I tried to call them multiple times and could never get them. Blown, who do you recommend on getting some from?
