Well, today was my first day ever at the track. My first couple times were awful due to bad launching. My best run of the day was 14.069 at 100.16. With an intake catback and tune, with horrible tires, I thought it was a pretty good time. Now the bad part of my day was after my best run, every time I put it into third, it grinds. Some people told me they think it's the synchro but I'm hoping you guys can back that up or or tell me what it could possibly be. Thanks for any help. It would be greatly appreciated.
