I had considered something like this several times for the same reasons as yours. My approach was to use cogged gears in place of the variator and clutch pulley and incorporate a toothed belt, basically a belt drive system. I figured this way would allow the use of a OEM style clutch, keep strain off the crank bearings and retain the transmission for gear ratio options. It's one of those rainy day ideas that never materialized but I think it could work if the motor afforded enough torque.
It would mean the motor would be suited for one purpose only, Flat tracking! and that's not a bad thing!
We run on a 1/10 mile banked short track that is great for the 150's. This track would be compared to yours as Bristol is to Talladega.
I'm located in RTP area and if possible, would love to come see what you guys are doing.
