Any cooling system changes needed? Can you go to a smaller radiator ie like running straight methanol?
I didnt... I keep the whole cooling system the same,
I just leave the fan and pump off a little longer then
turn on the pump and wait till the temp is up to 160
for the burnout... after the burnout I turn the fan on
for the pass... at the end of the pass I'm at 180
I don't run the cooling fan on my race car going down the track. In fact, I don't use the fan much at all! I actually lean the mixture with the fan off to put heat in the motor, I like to stage at 170F. I could use a smaller radiator, but this works for me.
My experience running race gas, E85 and methanol is that E85 cools more than gas, but not as much as methanol. That makes sense since you are not burning as much E85 as methanol, which evaporates and cools the motor in the intake ports.
