Hasport motor mounts that failed https://www.civicx.com/forum/threads/melted-hasport-motor-mount-bushings.81779/#post-1229056 have been replaced. The car is faster on the track! The theory is that the vibration at high revs was causing the knock sensors to cut back power. The only power mod is a TSP Stage 1+ tune with a 27Won intake.
At New Jersey Motorsports Park, Lightning track, last year my max speed in the straight was about 112-115, this year recorded 120 and still pulling strongly at braking time. No change to engine. I did get suspension work done, with custom camber plates, over the winter to get a degree or two more front caster and camber on stock suspension. It turns much better, so maybe the top speed is partially from getting through the prior turn faster, but I didn't become a better driver over the winter.
Unfortunately, the transmission failed. Now it is being rebuilt. 4th gear was damaged. Interesting that Honda HPD sells a stronger 4th gear, so it must be a known issue.
