3.4 pulley

[Tonyr]

If I replaced my stock pulley with 3.4 how much smaller of a belt would I have to go to?

You can get away with the standard size belt down to a 3.25'' pulley. But if you are concerned with slippage, you'll need the next smaller size (66'') unless the supercharger is raised - from an intercooler or supercharger spacer of some kind.

How much more hp are we talking about?

Thanks!
