I saw the MSD -V at power tour. Saw the guy pull away real fast. The car was loud as hell. There is also a write up in this month's Hot Rod about a product they are coming out with for racers on tracks. It uses gps, and some other sensors or something (doesn't apply to me skimmed it) to tell you how and where you could be faster, on the gas, on the brake, and where you are driving on the track. Looked pretty neat for those that do that stuff.
