1) I know you're upset, just like I was last week, but insinuating that someone might have done that to you on purpose is not going to further your argument. It was a mistake, one that sucks for sure, but as was gone over in the thread about my 2nd round loss at Gainesville, NHRA's position and rule is that it is our responsibility as a racer to verify the correct dial in.
2) you should really invest in getting a keyed balancer and having a keyway cut in the crank. If it spins on the crank, it will never hold properly again. It also sounds like you have a bad harmonic damper to begin with if your timing wheel keeps loosening up.

Hi Chad. On number one you are right as far as a dial in goes. It is not your responsibility to verify an index though that is the towers job.
On number 2 my damper did not spin on the crank. It is slightly tapered which was why we didn't cut it and the crank for a keyway. The problem was the adapter that bolts to the damper. came loose, causing the trigger wheel and the adapter to fall off even though I used red locktite and torqued the bolts accordingly. Vibration/harmonics (especially when on the 2 step) on an inline 4 cylinder is ten times worst than any V engine. Even though the crank was spin balanced (which I'm told is unnecessary on a 4 cylinder). |
