It's putting out a lot more torque than it's rated for by Ford. That's really interesting. Thanks

Are the aftermarket dyno numbers at the wheels? HP numbers seem awfully suspicious, although torque looks right on.

Yes, they are wheel hp and torque numbers. I will update the OP to indicate that.

Ford underrates all it's engines nowadays. Sometimes by a wide margin. They especially underrate the torque on their forced induction engines. Look at the dynos for the 2013 GT500...

Just as a comparison (bench-seat racing), here's a dyno for a 2012 mazdaspeed3:

2012 MazdaSpeed3:




Average Horsepower: 233.25
Average Torque: 269

Why do some believe Ford has under rated the Focus ST advertised power numbers?.

Because the numbers measured at the wheels on a dyno are coming in very close to(or above) what Ford rated at the crankshaft.

If we assume a 15% drivetrain loss, here are estimated crank numbers:

Average HP: 227.04 x 1.18 = 267.1 HP
Average TQ: 276.316 x 1.18 = 325.1 ft/lbs

If you're asking why Ford underrates the numbers, I'm guessing because the advertised numbers are minimums guaranteed, while manufacturing tolerances and tune variances allow certain (most) cars to be above that.

It goes like this,
If you buy an ST, and it dyno's above the numbers, you think "Thanks Ford, you made my ST awesome!"
If you buy an ST, and it dyno's below the numbers, you think "Screw you Ford, you lied to me!"
So when Ford underrates the numbers, you get more happy customers.
