Horsepower (HP) = (Torque x RPM)/5252
They need to measure RPM
Do you have any kind of printout from the dyno run?
That's why I never liked a Mustang dyno. To easy to screw with the numbers.
Mustang dynos are the only way you can really tune a car unless you’re at a track or on some back road with a computer. They also give you more real life numbers than a dynojet (unless the dynojet is loaded, which most aren't). Dynojets are more of a bragging rights dyno since you can't add a load to them. That is the reason Dynojets always read 30-40+ higher than a mustang dyno.
This is also assuming that the mustang dyno is configured right.
If 380 HP is correct............. I shut down the car when the HP graph dropped and that was at exactly 5k rpms. The dyno guy yelled the second the HP dropped and my tach was at 5k. Using the formula above I came up with..........
400 TRQ X 5000rpms/5252 = 380 HP
Until I can get to another dyno day, I'll have to go with having 380HP 400TRQ.
I've got the printout but I don't have a scanner and taking a digital doesn't show very well.

There not useless just the numberes vary to much from one to another. They are fine for tuning.mustang dynos are useless. any thing the operator enters can throw the thing off.
