I thought about doing something like that, but at the end of the day I just want to keep it simple. I don't have plans to upgrade internals / clutch stuff yet, so staying under 300hp is ideal currently.

I was reading on the vortech website that anything above 10psi you will need to change the bypass valve?

And is the correct gates pulley for that setup the Hundai Genesis one?

Thanks!
I shredded the gates blue racing belt because it jump of the edge of the pulley when I hit the rev limiter. I'm now running the 1/2 shorter belt and it's been good so far 2500 miles. I was a bear to get on but possible.

I'd have to measure one - which I have somewhere in my garage - but the OEM part number is 12305AA370 so you might be able to google it.

Thanks - Google says 5.826748713587742 - that may not be exact but it's close.

Do any of you have a part number for the belt required to run the 2.87 pulley? I plan on running it soon with 93/E85 Currently making 363HP on E85

Currently running a 3.125 pulley on 93, maybe making somewhere in the upper 200's, never dynoed. Wanted the smaller pully mostly for a little earlier boost rampup, tuner pulled a bit of timing on the top end.

Related question: stock clutch is holding fine on the power it is making now, if I decide to go flex fuel and run E85, think a new clutch is necessary? I don't typically drive like a lunatic, no heavy slippage/launches, mostly just rolling in-gear stuff.
