Sorry, but I don't agree. Not so much a racing secret from my experience. We had a NASA race two weeks ago at Summit and I started pressure slightly higher ending at 40psi and set a track record in race 1(25min race), then broke it again in race 2 (40min race). Part of it is car setup and driving style. My car has been setup by a pro driver/coach for more even loading and rolling the slow speeds. Because of this, the car remains very much at the limit before the apex and continuing to track out. I would still suggest targeting a 38 to 40 psi hot temp on cars between 2800 and 3100 lbs. I have spoken with a lot of racers and some Grand Am guys that show up at our races and have not been told otherwise. Your car setup and style may just be more confident with the temps.

You are clearly a successful and experienced driver with a well set up car to to be able to set 2 track records. Your response however wasn't clear on whether you have tested both higher and lower pressures to reach this conclusion, or were you able to reach this conclusion without any experimentation? Perhaps your record would have been even faster with lower pressures - hard to tell without testing. I've tested and am sticking to lower pressures, maybe with some more experience it will help me challenge your records. If you have tested a range of higher and lower pressures it would be great if you could share how the higher and lower pressures impacted handling and lap times.

In any event congratulautions on the records, that's great!
