Reason I am asking is I quickly ran out of room up front for the large radiator I bought for the project. It is 28" wide and I only have room for an 18" radiator.
Combo is a 347" LS, twin 67's, 20 gallon street cell in rear for driving, 3.5 gallon methanol cell up front for the track and no IC.

Thanks for the info!

E85 will run almost as cool as methanol. If you aren't running cooler, it might be too lean. I switched from running almost 200 when I ran race gas and now on e85, I have a hard time getting up to 170 to stage. Usually pull in water box at 160, stage at 170, 180 on top end, and back down to around 160 when I get back to the trailer. And it's ready for another pass after maybe 5 minutes. Hardly ever run the fan, and usually never run the water pump in the staging lanes.

^^ X2, Cooler with my Procharger car .
I changed to a 170° Tstat , same reason as above.

And X3 for a buddy that run a roots 8-71 SBC. He picked up a full second on E85 vs C16 and you can touch the blower, it's cold.
On C16 if you touched the blower you got burned.

If someone says it doesn't run cooler they are way to lean and not taking advantage of the fuel! My coolant fan could have fallen off and it wouldn't have bothered me.
