Ok guys, you sold me on the alcohol deal. One of the pros I keep hearing about is the engine will run cooler....how much cooler? I've always had a hard time keeping my big block cool, it's got a big copper radiator out of a Lincoln in it right now that barely gets the job done. It still heats up when I'm forced to hot lap the car or it gets hot outside (90+). I decided last year that an aluminum radiator was in order, will the engine run cool enough on alky to reduce the size of the radiator? If so, how much smaller can I go with it? One of those VW deals? I don't want to get back into a cooling issue, but at the same time, I'd like to keep as much weight off the nose as I can. Thanks, I'm sure I'll have more questions before this whole deal is done. ------------------

I'm not sure how much cooler it will run than gasoline. I do know that last year when I was running 2 classes every week and getting hot lapped a bunch, I had more problems keeping the trans cool than the motor. Alchy likes to be run a little warmer than gas, so I always stage at around 170*. When I stage at 170*, make a pass, get back to the trailer, its un-usuall for it to be over 185*, and it will do that after mutlitple passes. Later in the evening when I am hot lapping, its not uncommon for the motor to be at 170* at the sarting line, but the trans to be over 200*. 2 years ago when I had the car on gas for a short period of time, I was staging at 160* (water temp) and was lucky if it was as low as 195* after just one pass.

Butch, I put a small aluminum Radiator on mine. I got rid of the big heavy antifreeze hauler. You can get one from Howe radiator. They have some nice ones and can custom make it. I talked to Bryan McCulloch. http://www.alumrad.com/342i.htm
We have very hot summers down here but, I rarely have to cool the car down. Usually, it requires warming up some. Especially on the first time trial. I always jack the Rear end of my car up before the first run and let it idle in gear to get all fluids warm and at operating temp.
