I did find out that we are exceeding our radiators cooling potential so i ordered a griffin radiator with a trans cooler. Im hoping to eliminate one or two of the smaller coolers and lower our coolant temps as well. They were consistently 210 to 220 degrees with temps raising to 230 if you had some traffic at speed.



That’s awesome, great to hear the bigger cooler kept your temps 30-40 lower. We’re not remote mounted like you, but we will have a fan pulling the whole time.

Interesting to hear your engine temps went up. What was the ambient during your race? The one thing we’ve had good luck with is keeping the engine cool. Even on a 100 degree day, we consistently ran 195 even in slower traffic.

Very happy to hear the trans cooler is going to give us a chance.

If you’re not doing so, 100% synthetic ATF should help top.
