Chris, we tested an aero panel over the IC this same night, but which run this was, I'm not sure. I'll try to determine that by looking at the temps of the other runs. Also, the single gear dyno pull in 3rd won't build the heat that 4 gears and more load in 4th will generate.

This spread sheet also allows me to play with "what if's" in the input variables, like boost, temps, boost at given rpms, etc. Having the dyno logs and the plots helps with the what if's. I'm pretty confident if given the same variables, without the dyno plot, It would be very accurate. I've tested it on the other turbo's we've used and found it to be very accurate too. The biggest thing to get correct is the Peak Turbo numbers at the proper RPMS. That's where the peak boost/rpm comes into play.

that's a handy tool Tom...I'm not sure you can ever have too much data

Probably a bit much for many, but if you like comparing data and evaluating what your potential is based on known previous data, it's handy. I'll continue with improvements and my goal is to have the turbo variables worked out. This also will make for easy dyno comparisons from one type to another, based on at least those things in common such as boosted air temp, load (boost), rpms and atmospheric pressure at the time. With those common factors, the calculations will all remain the same, regardless of the dyno type.

Sorry, some of it is already on it's way to me. Some of the next stage has already been installed and close to getting tested.
