OK, so it looks like I am running into some belt slip with the stock pulley and I tried a shorter belt and a 3.5" pulley and it absolutely smoked it, going to have to upgrade and I am thinking I may as well just go to the 10 rib. Anyone know of a good conversion kit?

I don't know if this will help with any boost reference but here is what i see on my Whipple 2.9 build, 408 ~9.6 compression.
3.25 Pulley = 11 -12 PSI
3.00 Pulley = 14 -15 PSI
2.75 Pulley = 17 -18 PSI
Keep us posted on your progress.

I e-mailed Whipple asking why they offer this unit for the 6.2 Raptor and the 6.2 Camaro, but not the 6.2 GM trucks. They basically said that I can make it work if I want to, but I don't want to spend that much on a kit for a different vehicle to do my own trial and error on my one-year-old Silverado. Who in their right mind thought that a 6.2 Chevy with these high-flow heads should have the same blower as the 4.8, or a 4.6 Mustang???

Really? Yeah, he said I would have to have a bracket made but I would have to get into my e-mail to elaborate further, and I can't get into my e-mail right now. I will post up once I can.
