Alcohol is suppose to help keep a engine cooler but our track wont allow it in our class. Is there any additive thats out there to add to racing gas to help the engine run cooler ?

Pro Blend -"40 BELOW" has proven to be exceptionally better than Red lines "WATER WETTER" Cost is around 22-25 bucks. Dump it right into your radiator, with pure new clean water. They guarantee results.

What temp is it running at now? Without an oil cooler I wouldnt worry unless the temp goes above 215 or so. With an oil cooler as long as your oil temps stays reasonable the water can be a little warmer yet.

Probably nothing you can do with the fuel to help it run cooler except make sure you are not on the lean side. Running lean will heat things up in a hurry.

The extra cooling lines from the back to front of the intake, and from the pump to the center of the heads will help even out the water temps, helping prevent hot spots.
1:1 pulley setup with a good water pump will make a big difference. As will a good fan, assuming you have a properly sized radiator. GM 4 blade fan #405442 is the best fan you can get to help keep things cool.

Next thing would be an oil cooler, which would require more plumbing, as well as the cooler itself or a new radiator with internal cooler.

I agree w/Dirtbuster 1:1 pulleys do not go with reduction pulleys and a good shroud.
Mine never ran over 200 and was straight water no additives. Good Luck in 05

There not any additives you can mix with gas to make the car run cooler. As far as the gas is concerned you can increase the jet size a bit to richen it up that will help run cooler IF you don't have anything else wrong. I would take everyone elses suggestion and work on your cooling system.
