@peaches Good info thanks - was that on Nov 17th? Looks like ambient temp was pretty low that day, ~57F?

Going to Road Atlanta in a couple of weeks, will do some logging there as well.

Yes, temps were low (60 or under). I ordered a trac box (replacement for beastronix) with an option to turn the fans on, that should be a better option than using the heater.

I don't know if the rad fans will do anything when you're hitting track speeds but I think it would help in the paddock for cool down. My concern is that with ambient temps ~60F and you're hitting ~240F and have to turn the heater on, that when its 90F ambient you're going to see 270F which is the same issue I have with the dual cooler.

Someone tried to explain thermal dynamics to me at one point but too far out of my realm. From what I've observed in a practical sense there is a direct correlation between a change in ambient temp and a change in oil temp when you're running at full tilt with the dual cooler.

As far as the hood vents go I was reading one of Varus threads on their implementation and they did not observe a decrease in engine temp, the real advantage was some external engine components such as coils were at lower temps which might lead to longer life, and reduced hood flutter. I would think decreased heatsoak as well but I always prop my hood after a session. Ref: https://www.ft86club.com/forums/show...8&postcount=11

digging up the past i know, but im still toying with buying that el catless header. i realise i wont fully maximize power gains without redyno. but will it be BAD for my engine, throw off the air/fuel etc, if i replace the oe header with a catless el and dont re dyno.

i dont have the ecutek cable, and iirc, the tuner "sealed" my tune on my ecu, so no other tuner could open it and steal his tricks? is that right or am i out of my mind?
