If it is what I am assuming and you are saying the dyno is wrong because your guess at the horsepower was wrong then I can do nothing for that. 99% of the time we have found that the Dynapak reads 10% less horsepower than a standard dynojet roller dyno. The dynapak is a a tool strictly for tuning and eliminates any error by attaching the hubs to the car. If my assumption is wrong and you have another reason please let me know.



The way the Dynapak gets its horsepower is far more accurate than any roller dyno out there. Horsepower numbers can change depending on how a car is strapped down or what tires are used on a roller. Dynapak eliminates any of these issues by attaching the hubs to the car.

A different FD ratio would not make the HP read higher or lower. It would throw the RPM's off but it would not change the output. The only way it would change is if the gear ratio was so far off that the car wasn't in sync with the dyno. An example of this being.... The dyno sees 7k but the car only goes to 5k because the ratio was way off. If that were the case it would show a lower HP number and you would clearly notice this mistake on the graph. I hope that makes sense, if not I will try to make it more clear.
