it was developed by STP oil.he raced in the 60"s the engine weighed about 125 lbs,and was faster than all other piston driven race cars,it was also 4 wheel drive.it was protested by other drivers because they couldn't keep up with it,so the limited the air intake to about 60 SQ inches and it still out performed the other cars,he would have won the race but burnt out a wheel bearing,the engine was banned from racing.the last time it was seen it was setting at an engine builders shop in california,the shop i believe was Ed Pinks racing engine builders.the engine produced tremendous power and was small and light,it could burn almost any flammable liquid,the Fuel mileage was better than piston driven engines.also i believe there is going to be a supercharged 2 stroke engine that out performs 4 strokers soon,they don't burn oil with the fuel,so they don't pollute,the hp out put will be 3 times what the same displacement 4 stroke will produce,and be lighter in weight
Here's some Wiki to help you.......
I watched that race on TV. Both cars failed to finish due to a failed ($6.00) bearing in the fuel pumps.
