My car doesn't appear to exhibit the sluggish behavior that I understand accompanies heat exchanger/pump failure. The problem with my "epic" kill of an unimpressive R32 was no doubt associated with driver failure (my own). I thought the R32 was pretty fast until I got past him. Most of the race occurred on twisty roads with 25 to 30 mph speed limits. The R32 was driven and was handled well. I noticed he often had to feather and drift through curves while the SRT-6 stayed planted on the road. He was driving that car at or near its limits.
