We first caught rumblings of the new Shelby GT350 Mustang being dynoed by our friends at Motor Trend last week. Well, the results are finally in and many will be applauding the results.
Without further ado — the GT350 Mustang put down 467 rwhp (@ 7200 rpm) and 374 lb-ft (@ 4900 rpm) on K&N Engineering’s chassis dyno which shows a drivetrain loss of 11.2% (compared to around 12% for the 2015 Mustang GT). This is impressive considering ambient temperature was a stout 100 degrees with 20% relative humidity.
Motor Trend notes that the new 5.2L flat plane crank engine powering the GT350 Mustang builds torque slowly until around 3,250 rpm when it explodes:
“From 3,250 to 3,750 rpm, torque output jumps by a huge 27 percent. And from there to about 6,250 rpm, it’s essentially a huge plateau of peak torque with a few bulges likely caused by resonances in the intake system. Even then, torque starts to fall only slowly all the way to the fuel cut.”
