I just noticed the ZL1 has readable "skinnier" tach needles....
Is this the same for newer years? I have the 2010 fat needle that is useless.

Good numbers and right in line with what I would have expected on a Mustang dyno. My neighbors 2012 GT500 w/PP made 500rwhp/480rwtq on a Mustang dyno. Given the extra CID of the 6.2 versus the 5.4, the greater torque generated by the larger motor shows.

I think in a drag race, the 2011-2012 GT500 and the ZL1 are going to be a drivers race with the edge going to the ZL1 given equal drivers.

At 518RWHP if that engine is indeed making 580BHP at the crank then that would give us an 11% drive line loss.

The reason that the V6 Mustang and V6 Camaro can get the fuel economy numbers that they get is due to such low drive line losses. Consider that the V-6 Mustang is rated at 305BHP and gets a best 31MPG and the Camaro V-6 at 323BHP gets a best 30MPG. Consider that the Honda Accord V6 Coupe wwith 271BHP gets a best 29MPG highway, thats all 3 with automatic transmissions and consider that the Honda is 3,400 pounds compared to 3,450 pounds for the Mustang and 3,750 pounds for the Camaro. When you equip all 3 vehicles with manual transmissions the Honda does even worse as it has a rating of 26MPH highway. Compare that to 29MPG for the Mustang and 28MPG for the Camaro.

So what I am saying is the reduction in drive line loss has given the RWD platform new life as they are now capable of achieving fuel economy numbers that are competitive to their FWD counter parts. The fact that RWD vehicles use to have a driveline loss in the 20-25% range and now are in the 10-15% range is impressive. That some models in the past had a 25% drive line loss and now have a 10% drive line loss doesn't just mean better fuel economy. This also means better performance all around, consider that if it takes 300RWHP to get a 3,000 pound vehicle to 60MPH in 4.5 seconds. At a 25% drive line loss it takes 400BHP to achieve 300RWHP, this means a engine that not only consumes more fuel but a engine that is bigger and heavier all things equal. Also the transmission has to be beefier to handle 400BHP going into it, so the the drive line gains weight. So in order to keep the 3,000 pound vehicle weight you need to use lighter (more expensive) materials. At 10% drive line loss you only need 375BHP to do the same thing, though the difference of only 25BHP is a small difference. This difference becomes more pronounced as the power levels go up. When you are looking at 700BHP range at 25% loss you get 525RWHP and at 10% loss you get 630RWHP a difference of more then 100RWHP.

Did anybody notice that it doesn't do the full gauge sweep? Specific to 2012 or ZL1's?

Worlds slowest race video? I kid... 518! that is pretty much exactly twice the RWHP of the V6.

would be a bit of a disappointment to not have before and numbers at the track. I hope they do it for the sake of improvement. Horsepower is nice, but dyno queens are a thing of the past.

Doesn't that just mean the rings haven't seated yet??? A dyno break in is one of the recommended methods, so this will probably be one bad ass car---broke in right from the start.

At 2:36, that's the butterfly valve opening...and my guess would be releasing some "stuff" that coughed into the pipe while it was closed. I saw a little something come out the left side, as well.

The cars both sounded like they ran real well - I'm not all that worried about a little smoke early in their lives.

My 2012 has the skinny needles, all 2012 and up do, its not ZL1 specific. To be honest I like the 2010/11 gages better, they are more retro

My 2012 does the full needle sweep so I think this is specific to the ZL1

Can you confirm the stock psi? Also, Transmission. Seems as if the yellow car is a manual and the red "could" be an auto.

Also, an KR without heat soak? The SS's (LS3's and L99's) exhibit a ton of KR with stock timing tables.
