Cooling my car down is worth a tenth
My best times have come from hot lapping the car, I shit you not.
I will usually let it cool, then run it to normal operational temp in staging. This way most runs are close in temp(oil, water ect) regardless of ambient temp or amount of time between runs. Hot lapping has happened and didn't seem to affect it.
Same here!! I ran a fast car shootout recently and kept cooling the car for time runs for the ladder. Once elimination began I had to hotlap and it got faster every run. After leaning this I only ice the intake for 20 minutes and run it.
I hot lap usually. I'll let it cool for a few minutes between each pass. Some nights it cools for a long time waiting for our class to come up. I'll pop the hood while I wait.
my car is faster hot as well, the cooler I try to run it, the slower it gets.
I would be cautious about getting it hot with cats (& a catted tune due to the "cat protection") though, when the cat protection is active it can cost you a tenth or 2

I remember when the 5.7 hemi first came out and a mag did a thermostat test. The 160 degree made like 10 less hp and ran like. 2-.3 slower. The car (I beloved a charger) ran faster when hot lapping on the stock thermo.
