I sure hope that's not the problem. IIRC, a new a/c compressor is something like a $4,000 job.

Hot weather has a much greater effect on performance than running the A/C in my testing. Once the car becomes heat-soaked I may give up 2-3 seconds per lap due to both engine and tire grip losses. My personal best laps always happen with plenty of cold air at the intake when ambient temps are 50-60F here in SoCal.

Interesting. Come to think of it, I started noticing it when the weather turned hot. OTOH, I started using the a/c when the weather turned hot.
