When you really get them up and ring them out on gasoline these motors sure run hot. I was probably making more power on VP but it cost more and I spent a ton of money on Radiators and fans. A lot of racers in mini sprints are not really racing and working their motors to the max any how, these guys can get by with anything and nothing is going to get them going any faster. For the guy working them alky is really the way to go and no amount of weight is going to slow them down. Back when we ran gas our average EGT was between 1350 and 1550 degrees f. On Alky it down to about 1100 degrees. I put a smaller radiator on and I threw away my fan.
I can remember one expensive goodie. It was a 4 core Griffin Nascar radiator for my little Beast 600 car it cost $650.00 back in 1996 it worked.
