It took several pulls on the dyno to achieve a stabilized result. Each run eked out more power as the ECU probed the limits of the 91-octane fuel. The Mustang finally produced stable and repeatable numbers upon the 7th dyno pull.

With 250 lb-ft on tap at 2,000 rpm, torque starts out pretty strong. It then builds linearly and remains above 350 lb-ft from 4,150 to 5,500 rpm before tapering gently to the 6,850-rpm fuel cut.

Peak numbers are 365 lb-ft of torque at 4,350 rpm and 395 p at 6,600 rpm. All of these at-the-wheels figures were obtained in 4rth gear on a Dynojet 248 chassis dyno and include a 3% SAE weather correction factor.




Driveline loss for a solid axle-equipped car like the Mustang is typically 11-13%. This is a bit less than the usual 15-18% you'd expect on an IRS car, as solid axles have fewer power-sapping U-joints in their driveline. Hence, we should expect to see about 358-367 rwhp from this car.

Clearly, the 395 rwhp figure we measured is of particular interest since it implies one of two things -- either Ford is being conservative with its 412-hp flywheel rating, or the preproduction example we tested is unusually healthy. We're leaning toward the former, but we won't know for sure until we test a production 2011 Mustang.

 

I'm waiting to see how they gear they car. The previous generations have been good down low but they seem to somewhat die out once you reach higher speeds.

 

The whole notion of a drivetrain loss means absolutely nothing since its all relative to a particular dyno. Every type of dyno reads different; and even the same kind of machine has its own calibration. (Magazines try to way-over simplify performance figures for the general public. i.e. 0-60 times and drivetrain loss).

Those of you who are really experienced with dynos know what im talking about.

Either way, impressive numbers. My brother is looking at purchasing one once they arrive. They should perform quite nicely, especially for the price

 

Very impressive indeed. What a bargain in terms of power and price

 

wow niiice pulls

 

Ohhhhh YEAH!!!!!!!!!!!!!!

 

Can't beat it..

 

well the fully loaded ones will be over 40k+.

it's a bargain compared to other v8 fast cars, but that's still a lot of money for a mustang IMO.

anyway this thing should easily beat 4.5 sec 0-60. i bet my money on 4.3-4.4 sec range.

 

DaMn! Finally stepping up!

 

after seeing ford and infiniti up the game with big engines,
i'd like to see lexus offer higher powered models on their mainstream lineup.

specifically, a 450hp LS and GS

 

Infinti hasn't upped anything but their displacement do you still miss that point? The G37 is not faster than the IS 350 and the new M5.6 just got a 5.2 second run in edmunds.. Barely faster than the gs 450h they tested that got 5.6.

On top of that they make nothing faster than the IS-F and LFA.

Ford on the other hand is finally competitive as the camaro G8 and challenger had over 400hp available.

I think what Ford has done is fantastic. Infiniti for 20 years makes big engines that never have class leading performance.

 

I know a few owners that are temped to swap this DOHC 5.0 into their vehicles as it seems like a very promising motor.

 

Seriously! It probably would not take a lot of work to get this thing to rev to 8k!!

And thanks to Ford there is finally an alternative to everybody and their inbred cousin stuffing LS motors in the first thing they lay their eyes on.
