I have to agree , keep us posted on your numbers

 

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?

 

Scratch that last comment, these blowers do not like gatorback belts. Put a gates on and no belt slip with the 3.5" pulley

 

Great news!

 

That's good. I have found each system to be different, my Kenne Bell liked gatorbacks and my TVS seems to like gates.

 

I like your build, engine compartment looks similar. You may also want to check out reichardracing.com, they have ultra grip Cobra pulleys that will fit the Whipple 2.9. The notches in them that will help with slippage a it gives it a distinctive sound that i personally like as compared to the Whipple pulleys.

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.

 

updates, videos? Love to hear any new info on this set up. Thanks!

 

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???

 

The good part is the 2010+ 6.2 Camaro have the same accessory spacing as the trucks so you wouldn't have to change the water pump or crank pulley.

 

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.
