The torque curve wasn't as impressive as what posters here were leading us all to believe. I was almost expecting a twin screw like torque curve based on information posted. It has a typical N/A DOHC torque curve. Nothing wrong with it, just a lot of hype here before about the FLAT torque line.

Guy over at Insideline knows the deal.

I'm right....because in this case it's a Dynojet. On a Dynojet, it uses a mathematical equation based on the known weight of the rollers and acceleration of said rollers. If you use a gear that accelerates faster (in this case 4th gear instead of 5th gear) the rollers will spin up quicker (accelerate) and skew the numbers in a positive way. The opposite would happen if you used 6th gear (.65:1)...you'd have lower numbers.
On other dynoes, like Dynapack and Mustang, they are less sensitive to gearing as they use a different method of calculating the HP. But the Dynojet is VERY sensitive and you must use a 1:1 ratio (or as close as possible) so as not to skew numbers.
Inside Line and Mr. Kavanagh dropped the ball on this one. Shame.

Mustang Dynos are the most accurate. You can test real world scenarios under varying loads. People hate them because they don't give the "braggable numbers" dyno queens want to impress their friends and bench race. I posted my Mustang Dyno #s on a Shelby site and everyone was like "omg dude your #s are low, something is wrong". I just rolled my eyes.

yes.
and the torque curve is pretty good for a 5.0 dohc if u ask me.
the ls3 in the camaro makes about 320rwtq at 3k rpm about 350rwtq at 4k rpm and peaks just over 4500 at like 365rwtq. the 5.0 does pretty well if you ask me, for something 1.2 liters smaller

How can you possibly compare #s to this clearly proven bogus dyno chart?

I think they had to run it in 4th because the top speed is governed and she wouldn't redline in 5th gear. They did the next best thing and ran her in 4th.

I'm honestly not sure. I'm guessing the governor is set for 155 mph. I'm not sure if you can redline 5th with 3.31s gears out back. 155 mph 1 to 1 with 3.31s is 6400 rpm so the you'd never get to redline the car. I looked in the operators manual and it said to test in 4th gear. If the guy wasn't thinking it would be easy to assume 4th is 1 to 1.

If the speed limiter is still the same as 2010 then I believe it's 149 MPH. In that case the 3.31's would still be ok but 3.73's would top out at about 145@7000 with the 3.55's hitting 149 at about 6830 which I think was where they claim to have hit the fuel cut-off... Would they really advertise a 7000 redline but have the rev-limitter set under that to compensate for inertia? Did they run up against the rev-limitter, or the speed-limitter? More stuff to ponder.
