I tested the e fan solution last year - i thought i had it . I tested on friends cars and my personal Z's and i REALLY thought i had it but there were times when the temps flctuated too much for me. Popped in the stock fan and it did a FAR better job although in race conditions it wasn't perfect either. I have enough sensors and logs to demonstrate what works and what dosn't. I have to say at this time that unless there is a fancy fan and Fan controller out there that i don't know about - there is no true e-fan solution right now.
I have been playing with the stock setup and different fluids to get a setup that will stay cool at Sebring but no real sucess. I think this is the next biggest problem that the Z community needs to fix somehow.
