Currently, I have the Hayden 403 cooler. I'm just not too sure if that's good enough because I drive my car pretty hard. So I upgrade to a larger Hayden model or go with the B&G(I think that's what it's called)cooler?

I have the B&M because I like the idea of the bypass when its cold thing. Great for the colder weather. I have the 11"x11" one and it works great. That is the biggest one available where I shop, they have two smaller ones. The B&M is higher quality and better cooling from all I have read about them. I check the temp periodically and it does get warm at the track.

Thanks. JEGS sell them right? I'm more concern about the hot weather than the cold weather. It doesn't get real cold down here(Louisiana), but will get very hot often.

Don't go too big either. Tranny wear occurs when it's too cold as well. You want to maintain the temp at the optimal. So don't go bigger unless you are going over optimal. If you are going over optimal, go with one with a bypass.
