Somewhat related. I was in the Carousel at Summit Point two weekends ago and during the Spec Miata race, most of those guys were repeatedly on their rev limiters in the tight area. I guess it was better to wind it to the bitter end than lose the time up shifting and then down shifting.

(for the spec Mazdas)
going down to 2nd for the left at 5 gets you a better launch and with only a tap on the brakes entering the carousel , you are still within the power band and not hitting the rev limit until mid corner. Last place you want to be shifting is mid corner.
Better to hold your line and hit the rev limiter a bit and shift about flag station 7.
Remember also that a) the carousel at SP is not a typical race corner and b) you are talking about mostly stock engines using mostly stock engine management.

Bill, I didn't say it was right!
My point was that the dyno guy realized from ignition patterns that a single cylinder was cutting out, not random cylinders or some algorithmic pattern - that's all.

Well said. I love the Carousel. If done right, you carry a lot of speed all the way to 10.
See you in September. Hap will be with us.
