I havent seen over 145 in city driving with my 40k and 3600RPM converter. 180 is the max when at the Raceway.

Mine runs at 135* almost 100% of the time. I don't think it ever gets to 150* at the track.

Are you guys going through your radiator? I have a tru cool and it runs about 160 once fully warmed up no matter what. This is with 80-90 outside temps.

Yes, I run mine thru the radiator cooler. I also DO NOT use the cold-weather by-pass.

Never really check that often. When I had the Yank 3600 it ran around 200* if I beat on it hard in the summer. Even with the Trucool 40k I've seen temps rise to 195* on AndyC3's truck.

Heck just on my stock tranny cooler I am around 120-130 with everyday driving and getting on it a little bit. I saw 160-170 the other day when I was doing multiple WOT pulls and driving like a teenager that just got handed a new truck.


Will see how it does once the track opens up
