[QUOTE="'03 Sonic Blue, post: 2427216, member: 8510"] Everything that can get too hot, does. For now just the engine and transmission. I have a diff cooler installed and can keep temps under control on it. I've got a Fluidyne radiatior, removed thermostat, plugged the thermostat bypass hose, run the heater full blast (with dash vents pointed at passenger). Added water wetter to 50/50 antifreeze. Built appox 5 inch air dam under the radiator in place of the stock 1-1/2 inch one to help incease pressure drop across radiator. (The air dam seemed to trim itself to a steady state height during braking and cornering.) We'll see how things go at Gingerman. BTW, I don't think the Fluidyne radiatiator is much, if any, better than stock. But I don't feel like swapping it out at the track to get an apples to apples comparison. At MAM with 90 deg ambient temp, I could run about 5 laps (<10 minutes) before the ECM declared the engine too hot (244 deg F as read from the OBDII port) and would go into limp-in mode. Actually I didn't have to back off too much to get it to stay under control. It looked like I could add two or three seconds to my lap time and keep the temp around 235F. The tranny temp gauge only goes to 250F. We were running two run groups and only had time to take a quick peek at the brakes and tires between sessions. The tranny gauge stayed pegged all afternoon. At startup for the next session it would still be past 250F. The SVT engineer I spoke with at AutoBahn said the trans should be good for the upper 200s and I shouldn't be concerned about it. Now, I'm focused mainly on the engine. I think with the current set-up. I'm good til the ambient temp hits about 80 to 85F on a 2 mile course. I don't know about longer tracks. The out of the box factory cooling system was only good up to 80F at Road America. I've not run there in warm weather since changes have been made. --Mike [/QUOTE]
