  • What correction factor are you getting the crank HP with?

  • @Daytonaman675

    its not a correction factor, unlike most dynos and dyno shops that use a arbitrary % to make the crank correction, the MAHA actually dynos the drive train loss for each car. This is dun by measuring the amount of load resistance from top speed to 0 MPH during the roll out in neutral. it is so accurate that you can see the difference in HP loss between when the dif and trans fluid is hot or cold.

    IT’S SO IMPORTANT to remember drive train loss is NOT linier!!!!

  • @Daytonaman675

    The Percentage increases as MPH increases but as a expanding rate. Any one that is giving you a X% drive train loss needs to give you the MPH and RPM to be accurate.

  • @goodspeedperformance This was too much to hope for so I just discounted it entirely - That dyno should be the standard of the world not the dynojet.
