Which belt?

[Mike_11CTSV]

2011 CTS-V. What size belt is the right one for a stock balancer and 2.35" blower pulley? Is it a Bando 8PK1650? Do I use the stock idler, or a bigger one for more wrap?

Thanks.

Hi Mike,

Sorry to reply, that we have not done this setup to date. We hope to be doing this setup in the coming weeks, and hope to have this information soon.

Nobody's used your hub and 2.35" pulley yet? I'm gonna be the guinea pig? Great. This car is gonna hate me. I did testing for DiabloSport on her too.

Yes. Its just not the most common way to go. Most do the 2.55 upper, and then on to the lower and various options. This way you have more potential belt wrap, and less prone to slippage. Shouldn't be a big deal, but we just haven't mocked one up and tried here at LPE thus far.
