Hey Stevie...What crank pulley are you using for the 8.5" ?

Dont forget, Im not a Corvette....

Mine would be more akin to the GTO setup. I use a dedicated blower drive in front of the stock crank pulley. I had all my pulleys custom made by ASP ( Powerbond damper though )

Sorry to bring up an old post, but what kind of power was made after changing to the smaller pulley?

I'm thinking about running this very setup.

347 + YSi

Thanks,
Jon

It's nice to see something different done. That blower takes a LOT to be spun like it should!

How is your midrange power?

Midrange is good. This is on pump gas only no methanol.
