[Fot] cooling down a tr3

[Larry Young]

Chris, The validity of your reasoning depends on the air flow.  If you 
have enough air flow, you will have less heating of the air as it moves 
through. I agree though that it is better to have a large frontal area. 

On my TR3, I tried what everyone else has suggested.  Finally, I 
installed one of the commodity ($150) Chevy radiators.  It has about 1 
inch clearance on each side.  I've run it in 100 degree heat with no 
problems.  I agree with what Bill says.  When you have a large safety 
margin you know something is wrong when you get overheating.  When 
racing, you have enough to worry about, so this eliminates one worry.
