....Mark, Saw you out at the track and watched you make one of your passes. Was the new NOS setup working like you expected?

Launch,
Yes and no, the car ran OK, but not as fast as I had hoped. I stepped up the nitrous shot and it slowed down 0.05 , not what I wanted. I am starting to exprience the same high(6500+) rpm miss I had before. I think I might know what it maybe though. I found last night after the track that my new MSD distributor is not phased properly. If you don't know what that is, it means that the rotor is not lined up with the terminal on the cap when the spark occurs. This would be like making your spark plug gap twice or three times as wide. The spark has to jump the gap and the larger the gap the higher the resistance and the easier the spark can fail at higher RPM. I am buying an adjustable cap today and I will test it tonight. I hope I can work it out so I can start working on tuning my new carb. See everyone Friday.
