2019 Ford Mustang Shelby GT350 V8 Dyno Run


The gang over at MotorTrend got their grubby little mitts on a new 2019 Ford Mustang Shelby GT350 (not pictured) and headed straight to the dyno to see what the car really makes as far as power and torque go. The 5.2-liter Voodoo V8 engine has an 8,250 RPM redline and is rated from the factory for 526 horsepower and 429 pound-feet of torque at the crank.

The publication reckons that with the typical 15 percent loss form what the engine makes at the crank and what the car has at the rear wheels. That would mean the expected dyno numbers would be about 457 horsepower and 373 pound-feet of torque at the wheels. It seems that for whatever reason, Ford could be underrating the 2019 Ford Mustang Shelby GT350 that MotorTrend got its hands on. Presumably, it’s no ringer; the engine just makes more power than Ford claims.

The dyno runs for the 2019 Ford Mustang Shelby GT350 show 494 horsepower and 382 pound-feet of torque at the wheels. Those numbers factored up for power at the crank would mean the engine is making about 568 horsepower and 439 pound-feet at the crank. That is 42 horsepower and 10 pound-feet more torque than Ford claims.

Another interesting tidbit from the dyno sheets is that torque is very near its peak between 3,300 and 6,000 rpm when it begins to drop off. Peak power for the high-revving engine comes near the 8,250 rpm cutoff. MotorTrend dynoed a 2015 GT350 in the past and that car put down 467 wheel horsepower showing that the 2019 GT350 is making more power. Ford also appears to have underrated the Ford GT as one has been seen on video making more power than expected.

    The GT350 is probably the best mustang Ford has ever made. It just sounds like garbage with that wannabe ferrari engine under the hood. Currently, the Bullitt is the Best sounding mustang out of all of them. If Ford could tune the exhaust on the GT350 to sound like the Bullitt, give the GT350 the 10-speed auto, the updated headlamps and taillamps, The GT350 would be awesome. and maybe change that hood.

    I just bought a 2017 GT 350 two months ago and everything that last guy mentioned that he thinks needs to be changed…..I love

    What’s difference from 2017gt 350? Why new 2019 makes more?

    Ford says its normal for the 5.2 Voodoo to burn up to 2 quarts/1,000 miles. That’s insane. I’m ok with a little oil consumption, but having to add multiple quarts of 5W50 between oil changes is unacceptable.

    Ford just drops the ball on its cars there’s always something simple they could do but don’t. Why not have a 10 speed in the GT 350 it makes total sense.

    Best Race Car ever made is my 14′ Shelby Cobra GT500 SVT Track pack. End of debate!
