The Super F Synthetic fluid over Conventional Type F gets us that far as with regular non synthetic it was 200 after 3 passes. I have the cooler mounted under the car, facing the ground and it has a fan on it. Its the Derale "atomic" cool that we stock.

I don't have a cooler in the COPO since we can't cool the engine and blower off fast enough to worry about it, and its a T400 with more capacity.

You can be bybassed in the pump and just plug holes as mentioned or loop the lines. I keep a loop on the COPO so I can monitor cooler pressure.

I use your converter. What are your thoughts on synthetic Trans fluid?

Ed, ATI has their own synthetic fluid. Jim has been after me to try some, I've been testing other stuff, I can't give it an honest fair back to back test.

The way I look at this is from my own personal experience.
If you don't plan on going quick, back to back late rounds, either in S/SS or bracket racing, then you probably won't need an auxiliary trans cooler.

Mark, I like your comment and agree. I see no down side to running a cooler and you point out one very positive advantage.
