TQs were powered by Indians, Harleys, outboard motors, Crosleys and many other brands. I had the pleasure of driving for a few laps on Ascots 1/4 mile (inside the half mile. I had raced my Emmick Arrow II Go Kart on this track for years, so I new the place well) in an Edmunds TQ powered by a Honda 750-4 with Hilborne injection. It had been a successful car and had a winning history. As I quickly found out it would only run wide open and run it did ! You did all your driving with the wheels spinning wildly. You only kinda lifted twice a lap to get it to back into the corners and then back to flat footing' it. TQs are still being raced and are little jewels with v-twins and v-fours hanging in front of the left rear wheel. My wet dream is a XR750 Powered TQ.
Nicely engineered adapter to In-Out box to mini quick change rear end.
Seven years later Mario won his one and only Indy 500 in his Hawk which was his back up car.
