7064 is the larger frame. The 7163 is not out yet, but will be B1 frame and likely the largest possible B1 frame turbo. 6758 is the largest B1 frame currently available

Anyone waiting for updates from me, I apologize, but my clutch is slipping. I had some time where it wasn't slipping at 14psi, but now it's slipping there too.

EFR 6758 @ 14psi was coming around 3200 in 3rd on the street with AVCS (3.9 final 5-speed.) No AVCS was 38-3900. Probably somewhere in the 3500-3600 range on an EJ205 and below 3000 RPM on a 2.5L. Certainly very close to a vf39, maybe ~100RPM later? It's spooling better than my 18G/7cm was on my EJ205, but a good portion of that gain is the AVCS on the EJ207 swap that happened at the stame time as the EFR install.

Top end comparisons will have to wait until I have a clutch that can hold it, which is probably 2-3 more weeks out to get that in place and tuned.

~6mm preload is giving a WG pressure of ~10.5, but creeping up to ~13psi at 8k RPM, probably due to a bit of angle the actuator has at the clocking necessary for stock-ish location.
