If Tom makes 800 all hooked up at less than 8 pounds of boost (more like 5 most likely) that's still in the 650 wheel HP range. A live axle and slicks would be best for that if you want 9 sec 1/4's.
Just drive the car and roll power on and off. Don't drop the hammer or sidestep the clutch and you'll preserve parts. It's really a 'presentation' thing. Any of 'our' builders on here can find near 800HP n/a on 93 octane (in a 500+ CI build) with big roller cams, 400+cfm heads and a big enough Dominator.
But twin Paxtons is
outrageous.....
