I cannot under-express the thrill of running the HC to redline in 3rd, 4th and 5th. Seems very easy to drive in a straight line for 1mi pedal to the metal, but with the M6, one hand on the wheel, one hand on the shifter, one eye on the tach, one eye on the course... For a non-racer this was certainly a handful, trying to get every hp out without bumping the rev limiter.
My speedo showed a high of 175 in two of 1mi runs, 1mph higher than last Sept. The PS4S tires grabbed much better than the Firestone Indys last year.
Best “official” speed was 172.985. (Last Sept the best was 173.537.) They had a “glitch” on my best run and my ticket had the speeds from the car that ran before me (10 and 40mph off). Adrenaline Rush was there and watched the run and said they announced my 1mi as 173.something. No idea if I beat the last Sept run, and probably will never know.
