What is the Ideal water temp. I have always thought that 170 would be perfect. I've heard 160- 180- 190 & some at the track say theirs won't run good till it hits 200 But I don't know that much about this thats why I ask so many &'s. and I have learnt a lot in the last few months here. Thanks to all,
Andy

My BBC want run worth a flip until it gets at least 170+. I want run it if it's over 180. I don't mind it getting over 190 or even up to 200 when returning, but I'm not gonna start my pass at anything over 180.
My basic info Dart iron block, dart aluminum heads, CSR electric water pump.

X2...I'll leave a about 170...and if it goes above 205 returning to the pits I'll shut it down for a few minutes on the return road.

i use it in my sbc and i agree wit everyone when they say you see about a 10 degree drop at most.
My mod see anywhere from 205 to 220 dependin on the night.

Charlie, I have used it since 1967 in a 292 6 that ran on the highway but would not go in the woods without high temps and I found it helped a little , did not know why and bout 5 years ago I was told it got rid of bubbles which do not cool anything. Later J.Smith 4621 racing :D

Used it when I needed it. got 10 degrees less.

Who said I had a problem?
I was just curious.

Thx Jimmy, I put a bottel in the 69, it dropped my normal operating temp about 15 degrees, I was satisfied.

all aluminum 615 N/A 157 to 160 degrees

That would be me, If your using water wetter you have problems and they might not be associated with cooling.
