Against the front of the class, by track and class
| Track | Class | Sessions | Typical gap to class best | Closest |
|---|---|---|---|---|
| Watkins Glen International (3.40 mi) | HP | 9 | +4.654s (3.38%) | +3.836s (2.77%) |
| Virginia International Raceway (3.27 mi) | HP | 4 | +9.160s (6.77%) | +7.533s (5.57%) |
Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.

Letters to Fastrack
HP I Don’t Understand Your Transmission Logic
#36251 from Brian Downey · No action required · Minutes (2024-08 Fastrack)
Thank you for your letter. The recent allowance for carbureted cars to install fuel injection systems only permitted an alternate
method of delivering the same amount of air/fuel, through the same venturi/restrictor size, as parts for older carburetors are
becoming increasingly harder to source, while aftermarket fuel injection systems are becoming cheaper and more readily
available.
Asking for completely alternate transmissions, which increase the number of forward gears, as a performance benefit, is not
viewed as comparable.

Thank you for your letter, but allowing a higher quantity of gears beyond what a car came with originally, is not within class
philosophy. If the competitive balance of a particular car is in question, then a suggestion should be made for an adjustment
that's within the usual philosophy of the Production category.
