I have had 3days with the LS and and I love it. The question is how hot should it run at. it's always between 200 and 220 and this is on the street. When on the track it's going to get hotter so what is a safe temp?

Bingo. It's there to keep you from damaging your motor. I ran really hard at Hastings today and the highest I hit was 242 and that was late in a 30 minute session with 86F ambient. It won't go into limp mode until 250. A Porsche Carrerra had to pull off because he was running too hot.STIG302 said:While the technology used in Coyote is derivative of the 302R, it's not the same set up, right?
I'm guessing limp mode is an insurance policy Ford took out to keep from replacing motors.
That seems like pretty good cooling performance to me. I feel much better now.cloud9 said:Bingo. It's there to keep you from damaging your motor.

It’s true I’ve only had it go into limp mode one time at MAM when ECT hit 250 and I threw a temp light, but whether there’s no cooling issue is debatable. There was a racer/instructor that posted up he went into limp mode at PPIR (Colorado) last weekend when ambient was 95F. He would get about 3-4 laps before going limp. He even blew some coolant once. He said most of the cars were struggling though with that temp. There's another guy who posted over at TMS that he and 2 other LSs struggled with 105F temps at Buttonwillow this weekend:Fat Boss said:Boss Ls said:I have had 3days with the LS and and I love it.

Mark from Ford Racing said the Boss is designed to run at 250.

Oh man what a PITA. I wondered what you meant about getting your car back on the other forum. Well hopefully you're back on the road soon. This whole transmission thing is weird. Mine's been perfect (knock on wood) and I've tested it HARD 6 days and 1000 miles on the track already, not to mention another 2500 street miles. We went through the same thing on the GT500 when it came out and that was with a "bulletproof" Tremec 6060. I had my trans replaced on a TSB and my clutch twice. Some cars had issues and others didn't. Mine was just showing some early symptoms so I went ahead and had the TSB replacements done while I was still under warranty. I'm confident Ford will take care of you ultimately, it's just a hassle when you have to wait it out.JScheier said:
