If you want to measure db's so we can get some more concise readings, next time you guys have a rally somone with the latest iPhone could buy one of the utility applications. I have it installed on mine and it gives average as well as highest db Reading in a bar type format. Just find out the distance and rpm design rules use and compare. Easiest and cheapest way I can think of to take out the subjective opinion that keeps going round in circles. Particularly with the home made baffelectomy's. Would be interesting and good fun too.
