Here's a video of me winding out the MFI 3.2SS to 7200RPM in 1st-4th. This is a really great 915 with a Wevo gateshift and Motul Motylgear oil.

Love the video. Sounds fantastic too.
Matt just got back to me and mentioned your build. You’re also dead-on about that 2.00 2nd gear recommendation, and it’s pretty persuasive. Will be much better in low speed corners / tighter roads (North Carolina + AX) at the cost of shifting into 3rd / back down into 2nd more often (WV & less tight roads).
For those playing at home, Matt recommended a 2.00 (17:34) 2nd / 1.381 (21:29) 3rd / 1.083 (24:26) 4th - Matt was extremely thorough in his reply & shared a stock vs mine vs his chart and talked me through his rationale around the RPM drops vs torque curve.
I’m still tossing up whether to go to a shorter third (a 21:31 / 1.476) to keep things tighter in that 2-3 range where I do most of my spirited driving. Bumps RPMs by 350 at the 2-3 upshift though, which might be too short? 7k shift drops to 5.1k vs 4.85k.
