I've seen this done before, but not
as simply and inexpensively.

Back in the old days,(1960's) we just adjusted the tires pressure to vary the bite, for a certain amount of tire slipage for the same thing. Pop

Berg anti-shocker was essentially the same thing, just a smaller cylinder on the trans itself. But... I looked on their site and it's not available anymore.

This would be cool if you could mount it inside the tunnel somehow.

That's how I did mine. 3000# Kennedy pressure plate and a Berg 3 puck disc. Ran it for many years with low 1.40 to high 1.30 60 ft times. Broke 3rd gear once and one ring gear on a stock trans. I ran 8.5 M/T with 14 LBS air and 30mm torsion bars & adjustable spring plates on a 1550# pan car.

Tire pressure would be adjusted for the track surface on each lane, temp, etc. Ran at the national record in my class (D/MP) at the time. Old Indy car an engine builder helped me set the chassis up and a lot of advice. Never did break a gear or the rear end, but overhauled the transmission and rear end about 8-10 times per season. I also drove a A/A for a friend.
Remember the RamChargers team. and Don Nickolson in the Mercury Comet ? I would run against them for Street Eliminator back at that time. Pop
