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.

Well it was either that or Ragonk Force.

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

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.

How big is the crank pulley on the BRZ?

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.
