Dear Lynn,
Do you know of or can you point us to a good site on radiator sizing a= nd selection, cu in capacity, surface area, fin density, cu in of core= /hp etc?
 
easy to use a big one or go with empirical data of what has worked for= so and so but trying to determine what is needed to do the job?
 
As always, thanks for you valuable input.
 
PS, Randi has gotten the kart racing bug again, 20-30 years ago she wa= s into superkarts and shifters, now she is looking at single speed 125cc TA= G karts, same thing Tracy is racing now.
 
Regards C&R
