Nice work. That looks great. The footwell is very similar to the M8 where they did tunnel dump...the M8 simply has an aluminum perf plate. Your idea with the strap is great...easy to add 1 or 2 if your boot goes around it. My boot never gets hot...but that foot does keep warmer. Is actually nice. I have the PG turbo with tunnel dump, so does a buddy. We did not use the deflector. Only issue was on his sled...he installed a bit close to the track and it rubbed the track a few times...he just trimmed it back to be just past flush (1/8"). Never had a bog or any issues no matter how deep it was. And it was so deep that I choked-off an snorkel external intake sticking up 4-6 inches. You can right sidehill all day with no bog. Is great. Yours looks right on. Will come down to the can delivering similar backpressure and working with your motor.
