Rob,
I think I may mave misunderstand your prior response to my question regarding whether the numbers you posted were rear wheel numbers or fly-wheel numbers. When you responded that the numbers are "RWHP" (https://www.6speedonline.com/forums/...1&postcount=32), I understood that to mean rear wheel horse power (hence the acronym "RWHP"). However, the posted dynos expressly state that they are setting forth "flywheel horsepower" (still very impressive numbers).

That is what all standard Dynapack graphs say, however it is in fact the hp generated at the wheels.
From my understanding, the reason Dynapack puts this on their graphs, is because the Dynapack pods do actually have a small flywheel inside each pod, which is how the eddy current load is applied to the hubs. Since the wheels are removed, and since you aren't spinning a set of rollers (like on a Dynojet or Mustand dyno), Dynapack uses the term "flywheel horsepower" since "rear wheel HP" isn't exactly accurate either.
With the wheels removed, there is a bit less rotational mass, which could be helping out the power numbers a bit compared to a Dynojet. The Dynapacks I have worked with have also been a few percent higher then a typical Dynojet, but nothing to cry foul about since all dynos vary somewhat anyway.

If you're talking about me, your information is totally incorrect. My car hasn't even been dyno'd yet.

I hear what your saying Craig. I guess for me I just have yet to see a protomotive HIHP car go on a dyno thats not proto's dynapack(no wheels on the car-hub dyno) and post yoru findings. If any of you guys can get a dyno sheet from a dynojet or mustang so I can compare it would be greatly appreciated ( you can pm it to me if you like). I'm still in the tuning phase so it give me a graph to study.

As I posted in this thread https://www.6speedonline.com/forums/...=dyno+spinning; I attemped to dyno my car at a local shop here after I got it back with my GT30's, but it kept spinning on the dyno.
But in all honesty, once I trapped 148 mph while weighing over 3500 lbs, I decided dyno numbers didn't matter.
