Anyone using a gas carburetor on their mod? If so, what about cooling problems?

I run gas and had no over heating problems. I did not have a shroud also. But I would suggest using a shroud to help pull the air

1. Run a 160 degree thermostat and drill six 1/8" holes around the inner part the flange.

2. There should only be 1/4 - 1/2 of the fan sticking out of the fan shroud, you dont want it stuck all the way in the shroud.

3. Run a plastic air dam off the bottom of radiator, at least the same width as the radiator and at least 6" tall.

Using these three steps we were always running 190 - 200 degrees at the end of the race.

HP doesn't drop off much from alky, but the low-to-mid range TQ numbers will be a little softer. This is a good thing with tracks that tend to be a little on the slick side, as it makes the car easier to hook up and smoother to drive. Also, the 50% less fuel burnoff can make a huge difference in late-race handling.
