One of the tuner magazines did an article on dynos a few years back - took the same vehicle to 7 different dynos on the same day and got high to low variance of 58HP. Given the moderate HP rating of the vehicle that 58HP was an enormous variance in percentage.

All this is why one should never compare dyno numbers from one car to another when the pulls were made on different days, different dyno, different technician, different ambient comditions. Yet we always see people bragging about their dyno numbers or crying because their car didn't dyno as high as someone else on the forum.


Please note I'm NOT specifically talking about Brian here, or anyone else on this forum. Just speaking generally.

Brian, nice to see you spending the time and money to do this.
