dyno is just a graph ... is this sae corrected? What type of dyno is this? Dyno jet? Mustang?
historically you divide your torque and horsepower numbers by 0.83 and that is what is approximately at the crank. This reflects a generally accepted 17% drivetrain loss for the 2014 e63 4 Matic system:

yes sae corrected
and dyno mustang
my question is the hp wheel seem to be low compare to my wtq

your hp is always going to be low compared to tq in these cars. Full boost at low rpm’s + big V8 = gobs of twist. About the only way to get the hp to be somewhat commensurate is to get bigger/more efficient turbos. But it’ll still be a challenge.
But my question is those number are pretty much spot on on a mustang dyno with the mod I have ?
because everyone seem to have more than 600hp at the wheel
thank in advance
eric
dont know if it’s still like this but, Mustang dynos used to be called ‘Heartbreakers’. They were notorious for reading considerably lower than Dynojets. Are you comparing them to other Mustang’s. And...even then...weather and calibrations can cause variances. Take her to a track and see what she traps. THAT is a pretty good indication of any mod increases.

So basically on stock turbos tuned t stage 2 (maxed out, basically) , does the car feel like it runs out of steam as speeds climb due to the HP being much lower than the TQ?
Thats the same exact time that the EC stage 2 tune+catless dp+air filter ran in the other thread with timeslips of 11.0@128mph. I forgot which thread it was where were speaking of it,
Too bad you deleted that 11.0 @ 128 --- that's on winter tires? And you ran uphill at 0.27% slope? That would be a very nice run.. the difference between 11.22 and 11.0 is significant.
Either way, your engine is running strong I wouldn't worry about that whp number.

i will check at home maybe I have it on my iPad
its 11.01 at 128.1

its funny how the w212 e63 on stage 2 is running exact same times as w213.
We we were just discussing in another thread results of EC stage 2 tune which ran exactly 11.0@128, time slips ad all posted there.
the mustang dyno explains it as they read significantly lower than a dynojet. Similar to the w212 on a dynojet your stage 2 w213 would likely dyno at around 600+whp and 750+ wtq.

but here the result on a mustang dyno!
