if anyone is interested, (dont know how this applies to the ITB intake), the book Optimizing Your Ignition by Dr. Christopher A. Jacobs (the Dr. Jacobs from Jacobs Electronics) shows how to dyno your own car using a stopwatch and a pad of paper. and if your measurements are accurate, the dyno is accurate to 2%!!
now how to get quarter mile times out of the weight of the car and horsepower...
