I am a HUGE fan of the 2010/2011 Mustang, but I think I am going to blow a big hole in these dyno results.

It comes down to Torque/Liter. Serious engine guys (not me) know that naturally aspirated horsepower comes from revs, and torque comes from displacement. You can rev an engine sky high to make power, but your displacement has the final say in how much torque you can make.

Here are some examples:
Ferrari's 458: 88.9ftlb/L (self proclaimed) record
Porsche 3.8 GT3: 83.42
Honda S2000: 81
2011 Mustang GT: 78
BMW M3 E92: 73.75
MB C63: 71.5
Camaro SS: 67.7
2008 Viper: 66.7

I listed some high tech and low tech engines there to show you a range of capabilities of engines right now (and you can see how relatively 'low tech' the LS3 motor is). If the 2011 GT makes 365 torque at the wheels, then using 13% drivetrain loss, is 420 at the crank, which is 420/5 = 83.9ftlbs/liter. HAHA, LOL, NO WAY. Their technology isn't there with this engine.

So all you Camaro fanboys, you can relax and use my argument in your intarnet debates until better numbers come out.
