Thats uncorrected. That would be about 366 whp sae, if that. Thats also a Mustang dyno. You will never see a properly calibrated Mustang or Dynodynamic dyno read higher than a Dynojet. Never. Just look at the E9x M3's that dyno on properly calibrated Mustang dynos or Dynodynamics and you'll see they dyno 10-20whp less than a dynojet. Some places like autowave in CA, put a correction factor of 13% so that their Dynodynamics reads like a dynojet. However, they dont input any weather correction factor like SAE or STD...

My 423whp SAE run above, was 433 STD, and probably 445whp uncorrected on a Dynojet.

Also, in dynos like Mustang dynos, Dynodynamic, dynapacks, its esay for the dyno operator to manipulate runs, since he himself has to put in or not put in correction factors, unlike dynojets in which they are already pre-set and cannot be manipulated.

So no, that is not a real 386whp SAE mustang dyno run...

However, GT3's do have and incredibly low powertrain loss. About 10-12% only (factory claim). And its confirmed when stock 997.2 GT3's put down 396-400whp SAE and the claimed crank is 435hp. All GT3's engines are hot dyno'ed at the factory, to ensure they put down 100-105% of the claimed power.
