5.3 with Roush TVS1900 and 2.9" pulley. 10psi

Mods in sig. Figured it would be around 12-13psi, but engine is moving some air.

 

2.8" blower pulley, 10% O.D. power bond. 10.5lbs. 2002 2500hd 6.0l, 218/233 .578/.578 112, mildly ported 317's, shorty headers. Still running stock throttle body and air cleaner box.

 

I had to order a power steering pump from Innovator West. While I was on their site I noticed they now have a 15% OD crank pulley. Anyone running one yet?

 

Interesting...I wonder how close that puts it to the waterpump pulley. I know my 10% OD one is pretty dang close.

 

They're 8.35" vs 8.00".

 

Stock crank pulley, ProCharger D1-X 3.7" is 13 PSI for me.

 

Need help with locating 8-rib Radix drive pulleys. I've been searching online retailers but no one has them on the shelf, and the one quote I've received is $190 and 4-6 weeks to deliver! Any assistance is appreciated.

BOOST: With 4" stroked LS6 block (383ci), -7cc dished pistons, AFR 225s with 72cc chambers, SC1 cam (cam card below), ASP 8-rib OD pulley set, MP122hh with 90mm TB and 3.1" drive pulley, Volant CAI, Dynatech LTs and catted y-pipe into 3" Corsa Touring catback, Alkycontrol with M10 nozzle, 3.42 gears and 29.5" tires... I am getting 8-8.5 lbs peak boost at 3750 rpm, depending on the ambient temperature.

 

Get in touch with these guys if you need a pulley: Smoothflow Pulleys

Even if they dont have it listed on their site they can probably make it. They have made several for me and I have been very satisfied.

 

 

I think they're all screwed up. Stock diamater is 7.48". They have it listed as 7.25".

I will say this... I have a powerbond 10% OD and I can tell you beyond a shadow of a doubt that another 5% would not fit with a factory water pump pulley.
