What choo no wanna run Spec RX-7 anymore?stephen said:What does everyone do to combat overheating in their classis SER's, i just got one for NASA/SCCA racing and have heard they have overheating problems frequently
As has been mentioned, a larger water pump pulley will help. I have one from a Stanza on my car -- not sure what year it's from (installed by some shop in NoVa ), but it's probably bigger than the Unorthodox Racing pulley.
You can also make some kind of "ducting" to block the sides of the radiator to force air through. I have this, too. Originally made out of cardboard and racer's tape, it's now a little more permanent with aluminum sheet.
Also, a front splitter or air dam might help (I recently constructed one similar to the Paule/Kojima SE-R Cup car made out of polyethelene, but haven't raced with it). Or consider something like the one on Scott Giles' 'Teg.
