i recently dynoed my car on a dynapack and came up with 442/417... my question is if anyone as had any experiance with dynapacks compared to a dynojet i have heard that the dynapack dyno will read anywhere from 5-10% lower than a dynojet... i still have some tuning to do to get to a final number and then i will put it on a dynojet to see where its at.. just looking for some insight on the 2 dynos thanks

 

The Dynapack I use reads 9% higher than the Dynojet next door. Same car, same day, 9% difference. I attribute some of that to lack of rotating mass ie. the wheels and tires.

 

In my personal experience dynoing my 2300 mile '09 Cad CTS-V automatic (A6) the Dynapack will dyno about 13% higher than a Dynojet. The chart is pretty self-explanatory. Also, the manual trannies (M6) dyno about 38 or so RWHP higher than the automatics (A6). So do not compare an auto against a manual as shown below. I do have a couple of separate charts for autos only and manuals and a comparison break down only if you would like I can post them. HTH
