If you are talking about race track Gremlins ... hmm that seems to be part of the sport.
I switched from offroad motorcyles to drag racing ... wow... 9 years ago. I had problems that I solved driving home, problems that took years to solve, and problems that renowned experts would help me with only when I thoroughly understood the problem.
When we went from running in the seven.teens into the 6's we learned that every tenth was a mountain. I spent two years with my goal being trying to get in the 6.4x's .... and next year we are going to skip the 30's entirely and set it in the 6.2x's (thanks mainly to a new chassis with ton's of carbon fiber and an third stage of nitrous).
I also paid $100 to join a website sponsored by Ynot racing called
Drag Race Tech Support |. I was pointed that one by one of my buddies and immediately said "no way anybody is going to give it away for $100" and I was right, but it was worth $100 to prove it to myself.
Drag racers are all helpful ... to a point. They will tell you enough to keep you in the game, but they aren't going to tell you all of the secrets they know. I'll never forget the sportsman motorcycle racer who came over and told me what was happening when we couldn't cut a light to save our life .... nor the comp racer/engine builder who totally tried to steer me the wrong way when we had problems after switching from one carb to two.
So while it is another of your self proclaimed "interesting questions" you are not going to get the satisfaction we'd all love to see.
I always thought ... well if they don't have drag racing in heaven, maybe we can all sit around and talk about all of the lessons we've learned. That would truly take an eternity.
