Mustang Power! We Dyno the 2011 Ford Mustang 5.0 V-8 and 3.7 V-6 - Wide Open Throttle - Motor Trend Magazine

2011 Mustang 5.0 (4th gear pull, 15% powertrain loss)
Claimed horsepower: 412 hp @ 6500 rpm
Claimed torque: 390 lb-ft @ 4250 rpm
Actual horsepower: 435 hp 6500 rpm
Actual torque: 404 lb-ft @ 4400 rpm

2011 Mustang V-6 (3rd gear pull, 15% powertrain loss)
Claimed horsepower: 305 hp @ 6500 rpm
Claimed torque: 280 lb-ft @ 4250 rpm
Actual horsepower: 308 hp @ 6700 rpm
Actual torque: 287 lb-ft @ 4000 rpm

"The Mustang 5.0 is certainly the most impressive with 435 horsepower - if you can believe it, that figure put its well over the top of both the Camaro SS and Challenger SRT-8. Even though the difference between Ford's claim and what we discovered is not as great, the Mustang V-6's output is no less impressive - especially when you consider its claimed 31 mpg on the highway.

Of course, the best news we discovered on Friday we can only hint at. We believe those dyno figures just have to be accurate, given the outrageous numbers these two 'Stangs threw down at our test track. But you'll have to check back with us bright and early Monday morning to find those out... "

Woo hoo!! I can't wait to see those 1/4 mile times. Is it possible that Government Motors and Fiats western arm will be disgraced by a small cube V-8

What i am most anticipating is driving my new 5.0 like a real sports car. Not just a straight line boxcar racer with no turning prowess.

My gut tells me this car will be a orgasmic daily driver that makes all the right noises, good turn in, braking, and road feel.

I cannot wait for Monday's swarm of "holy ****" articles and I cannot wait for my delivery!

My driving gloves and sunglasses await.

Edit: I just read the article. 365 rear wheel and they interpolated it back to 425.

Are we really to believe the new 5.0 is putting down 425 REAR WHEEL HP??? That is like 500hp at the crank shaft.

I can't believe I still haven't ordered one yet . . .

thats their crank numbers. Still better than OEM.

Here is their wheel hp #
3rd gear (1.69:1)
Horsepower: 365.26 hp @ 6600 rpm
Torque: 335.27 lb ft @ 4500 rpm

4th gear (1.32:1)
Horsepower: 377.99 hp @ 6500 rpm
Torque: 351.44 lb-ft @ 4400 rpm ​

5.0 Stang weighs 3606lbs and has 430-445 hp/ 404-415 tq
Camaro SS weighs 3849lbs and has 426 hp/420 tq
V8 M3 weighs 3704lbs and has 414 hp/300 tq

We'll see what weight advantage and new suspension upgrade does for the 5.0! This is going to be a unforgettable summer!

I don't think anyone is claiming 425rwhp. Just 435-445 crank hp calculated from rwhp numbers below 400.

Let's also keep in mind when the 1/4 mile and 0-60 numbers come out, it prob not on the very popular 3.73 gear upgrade

I think both the V6 and V8 should come standard with 3.73 gears. With 3.73s you would still get good mpg but a lot better acceleration. Both of these stangs are going to be great.
