Mustang Dyno MY2011 P31
93 Octane. All stock. 75F-80F. 6800 RPM
1st Run
377WHP
329TQ
2nd Run
394WHP
346TQ
3rd Run
396WHP
347TQ
4th Run, 80F. If it was colder...
406WHP
354TQ
Happy with results. But first run did break my heart. Will post a scan tomorrow when I get to a scanner. Technician/Owner mentioned that he's done thousands of runs and they have a solid ~18% loss on their Mustang Dyno. Only two Mustangs in Houston. That would equate to about 495BHP. Only one other C63 was ever dynoed in his shop and it only did ~365WHP and 330TQ final run and did not have P31. They took it to a dynojet and it did 390WHP. He told me that my car would read 430 low to 480 high on a dynojet. Either he's crazy or my car is a freak?
P.S. He also mentioned that if it were in correct winter temps I would read up to possibly 20WHP more. He also asked me what it ran before my mods after the final run
. All this talk makes me want to track it.

C63 AMG
I dyno'd my car once, it said 360RWHP. That was tuned. That works out to about 440HP at the crank..
Which is not true at all.. Dyno's are junk. I ran 119MPH at the track tuned and 114-115MPH stock...

But they are useful for mods and such. I know there are infinitely many variables that alter readings.

Nice numbers! Thanks for posting that information. Always good to have some sort of idea of what the car is making.

So, with an absolutely STOCK P31, you've got 406HP at the treads. What did your dyno man say that this would equate to at the fly?

They're going to push the motor to 100hp/l for the SLS black. Who knows which motor is truly wrung out?
