Mike, did you find that a higher rated (or new OE clutch) was required in general for the higher boost pulley, or specifically for the pulley + E85 + track conditions?

If I've read and understood the reporting correctly, you can run the pulley on 93 octane under street conditions, but you need E85 or 100+ octane for track conditions. That's straightforward enough, but if a higher spec clutch is also a must for track conditions (or even street conditions) then I'd like to confirm this for a proper set-up.

Thanks.
