I have a Hellion T-76 Turbo on my built MMR Motor, with a Lentch full manual Auto. In that I have a 4500 Stall converter. It would over heat quick on the streets (tranny that is) So I installed an F-250 super duty tranny cooler. Now I am having no over heating issues. However I am thinking it is still getting too hot in the converter on the street with the high stall. Oh and it's non-lock up as well. I would like to know what do you think is the best street strip converter I can get for my Cobra? I have run a best of 10.24 in the car so far and plan on upping the boost in order to run the just out of my reach 9 second pass. With that said I am running 3:73s in the rear and am going through the traps at near 6500 rpms. What gear do you guys think I should change to as Upping the boost I am thinking it will turn a little harder on the big end. Thanks for any help.
