I'm going 8 rib and plan on getting a ati super damper instead of the powerbond, still overdrive though. hoping for around 10lbs but might make more. not sure

I've been told that no need for ati unless you have a balancced engine assembly. That's why I'm going with power bond...

weird, I've never heard that. many people I know have been pushing the importance of a good harmonic balancer on me so I decided to go with ati. maybe someone will chime in and explain

I have an 08 sierra denali 6.2 with a tvs1900 and 3.1 pulley (3.1 came with kit). When i first installed it, truck was completely stock with blower and made around 6psi. I now have 90mm TB, 1 7/8 longtubes, and dual 3" exhaust and boost dropped down to about 5psi. Wondering where yall think i would be at if I install 10% overdrive pulley and 2.8 blower pulley? hoping for around 10psi.
