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

Keith Pittman who has had some really good runs this year like winning a race at Batesville and making the big race plus numerous other top finishes runs a Braswell gas carb, and he does use a fan shroud, with no cooling problems. Also keep in mind he is based out of Texas and runs this thing during the heat of summer with no problems.

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.

Is the car easier to drive on gas when it slicks over? How much horsepower do you believe you are giving up if any.
I've always thought that gas was good idea due to less changes in the chassis due to less burn off.

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.
