Chevy Camaro ZL1 lines up against Ford Shelby GT500 on the dyno

Inside Line took the 2012 Chevrolet Camaro ZL1 and 2013 Ford Mustang Shelby GT500, together, on a field trip: to Westminster, California where where they were both tested on the same dyno at MD Automotive, run the by same operator on the same day. In case any memories need refreshing, the specs run thusly: the ZL1 has a 6.2-liter supercharged V8 belting out 580 horsepower at 6,000 rpm and 556 pound-feet of torque at 4,200 rpm, for a 0-60 time of 3.9 seconds and a top speed of 184 miles per hour. The Shelby GT500 rocks up with a supercharged 5.8-liter boasting 662 hp and 631 lb-ft, for a 0-60 time of 3.7 seconds and a top speed in excess of 200 mph. Both get the power down via six-speed manual transmissions.

All things being equal, the dyno returns should have them split by something like 82 hp and 75 lb-ft. But good luck with equality, at least on this day: the Camaro charted 497 hp and 497 lb-ft, a the kind of 15 percent drop you might expect due to driveline losses, and just 11 percent of its torque sapped.

The GT500 would have none of it, charting 595 hp and 603 lb-ft. That leaves an on-the-road gap of 98-hp to the ZL1, and even though it loses more torque percentage-wise, it still comes out at an absolutely insane 603 lb-ft

595 rwhp... wow

thats around 700hp factoring a 15% driveline loss

The GT500 is by far the best new car for under $60K with 600hp and factory warranty. Kudos to Ford.

Is 600 whp, that's pretty close to 700 hp.

Crazy times.

Is only that thing is 4WD, it would run 10s stock

Ford underrated the motor! Or the drivetrain is insanely efficient!

So far tuners are picking up 50hp/50ft pounds of tq on just the tune, lol just the tune. no pulley's or exhuast work yet lol if thats not a back hand to chevy i dont know what is.

The motor is most likely underrated at 662hp.

I've heard that official SAE hp figures are under hot conditions with some heat soak. This would obviously affect FI cars more

The Chevy motor is 0.4L bigger though, so if the level of mods and boost level is the same, there is no replacement for displacement.

Okay yes the Chevy push rod motor is 0.4l bigger but we all know that dual over head cam motors are far more efficient. and look the "smaller" motored car is spitting out on this test nearly 100hp more at the wheels. Mods, let the modding begin the GT500 is already at a 100hp head start and it is far from bieng stressed and lets keep in mind its a fully forged motor where as the Chevy is not I dont really need to go any further...

I am not going to argue about this. But I don't think push rod is any less efficient then dual over head cam. Just look at all the modded LS7, LSX and LS9 in the world, they make huge power. They don't make any less power then any Ford V8.

I don't favor either side since I am not into them, just telling it like it is.

I preferred the Mustang to the Camaro even before they made these two cars, and that hasn't changed. Even though the Mustang is a great performance bargain I would still prefer one other car over it, and that is a used Z06. I would personally go with a used Z because as I see it you have a great weight advantage, very similar track numbers givin that the Z has only 505hp, and lastly the Z06's awesome track record in the handling department. Of course, I am Vette biased individual, (my name says it all), but another thing that turned me off about the new GT500 is when I priced it up with the options that I wanted. $68k!! Say what you want about this car, but I can't justify putting down 68K for a stang. I will say that I saw one in person on the road yesterday and thought it looked great.

Not argueing with you you either and didnt mean to turn it into one. Hell i own an LS2 powered GTO right now and owned a C5Corvette with an LS1 now and yes they can make great and insane amounts of power i've owned several of both camps in the past. Yes both will take to mods greatly. But the Ford hands down will best the Chevy as it sits mod for mod. As the Chevy to out gun the Ford will need to have the motor pulled and have forged guts put in to get insane power where as the ford is already there. Lets look at previous GT500 that are running huge Kenne bell or Whipple superchargers or TT's or Ford GT's essentially same motors there are plenty well over 1000hp hell quite a few Ford GT's in the 1500hp zone from Heffner performance and I hate to say this name but that Texas tuner that are putting out insane power on factory stock long blocks. Your just not gonna do that on a factory stock LS motor without tearing it down and doing forged rotating assembly and and head work it's not cheap i've been down that road.

The pushrod is less efficient just because the DOHC heads can flow more air. There IS a replacement for displacement, it's called airflow. There's no reason that a pushrod can't also flow that amount of air, but since it's a pushrod with no variable valve tech, it will idle terribly unless the engine is very large (like the LS7) and not be good as a daily driver. All while the DOHC purs like a kitten. This isn't an opinion and not up for debate, it's a fact.

Take a look at what the Coyote motor is doing to the LS3 in Mustang vs Camaro land. I giggle a bit when an SS tries to race me. I'm srs bsns when a 5.0 does. (I've seen enough basic modded ones trap 116-117 to realize that I might get beat).

There's a shop that already has the 2013 GT500 with simple bolt-ons (a pulley and an intake and a tune)running 10.0s at 141mph (yes, that's ONE HUNDRED AND FORTY miles per hour trap speed). It took Leigenfelter doing >$10k in mods to a new ZL1 to get it to run high 10s at 132ish. This battle is over and pushrods lost. We'll have to wait for the GM answer to the Coyote motor tech, and they'd better not release another pushrod as Ford still hasn't added direct injection nor made a high performance version of this engine.

Ford FTW.

My best friend is a die hard Chevy lover, and I intend to make him eat crow today. He has been insisting that GM always underrates their motors by large amounts to throw off Ford, and that thrown on a dyno, the ZL1 will easily make more power.

The little bugger isn't picking up his phone today >.<
