OK, need to repair a machine. Last words from me on the thread:
True B-20 or biodiesel sold at the pump has less energy than #2 diesel. Veggy oil is lower than both. I would not be surprised if he sprayed it. It's common in diesels to spray nitrous, more so than cars.
StanBack, I'm kidding about the race. But my SCTA DT entry did drive to El Mirage, then race, then drive back, and still drives on the street, and is smogged and registered. It was my daily driver until the cage wrecked for street use.
It is still quicker 0-130mph than a ZR-1 Corvette. By a lot. And it's slow by today's standards. It's vintage now.
