Default 2012 Shelby GT500 “Road Runner.”



Quote:
Spies have caught a pack of “Coyote” powered Ford F-150 pickups undergoing hot-weather testing. The 4-vlave 5.0L V8 engine is expected to pump out approximately 400-hp with a maximum torque of 400 lb-ft. Ford plans to replace the 5.4L V8 engine with the Coyote V8 in 2010. The naturally aspirated engine is expected to deliver 5.4L V8 performance while providing an increase in fuel-economy.
It was previously reported that the 2011 Mustang GT is expected to carry the new Coyote 5.0L V8 and is currently being tested in the United States.
Sources now say that Ford is also working on a twin-turbo charged version of the 5.0L V8 Coyote – code-named “Road Runner.” The engine is expected to find its way under the hood of the Shelby GT500 in 2012 and possibly under the Ford F-150 Harley-Davidson edition. It will deliver well over 500-hp.
The current 2010 Ford Shelby GT500 is powered Ford’s 5.4L V8 making 540-hp.

"Road Runner"

I know, let's code name our engine after one of our competitors old cars!

Since they are calling this one "Road Runner" is the "Coyote" going to blow up?

Very interesting. If this holds true, I wonder what kind of $ it would take to bring the Mustang GT up to GT500 specs.

I think what they were going for is a Loony Toons reference. With the Road Runner always being faster than Wil E Coyote.

So the 2010 GT500 does what 550 or so HP? That’s coming from a 300 or 315hp V8. Since the 2011 GT should have the new 5.0l 400 or so hp V8 the GT500 would be much more powerful with just a SC on it. Wonder why they are going TT, you should be able to get over 600hp from a setup like that, easy.

Guys are gaining an easy 200whp by just putting a SC on the new Camaro (and various exhaust stuff) I’m sure this would be beastly.

Ever heard of reruns?

And since there's no more Plymouth, the names are up for grabs.

A mustang GT motor and GT500 motor are significantly different. the biggest changes being 4.6 vs 5.4 L displacement, 4 valve heads vs 3 valve, and there are plenty of other differences that account for the extra 200 hp. That big screwbox on top obviously helps alot too

With that being said, an 5.0 starting out with 400 n/a and more modern tech, bumping it up to 5xx with two turbos wouldnt be hard at all. Hitting 6xx would only be a matter of upping the boost.

For reference, I wonder too if it is in reference to the Coyote race engines, Foyt I believe. They were Ford engines, but designed for Indy, ie. cosworth. I am not sure, but wonder if there is any relevance there.

Whoops you are right, the GT500 uses the iron block, all forged I think. Still like you said 100-150hp bump from twin turbo's would be easy.

Think Chrysler will have something to say about the Road Runner name? I sure hope not. Car companies seem to get pissy when others "succeed on their names"; GM sued the band Chevelle for using their name.

termi's are still putting down 900 rwhp all day long on twin and single turbo setups, Evo performance in PA makes a nasty kit for the 500 that is good for over 1000 rwhp on the stock block/internals and is capable of spinnin up to 7krpms

yeah, all forged. However, I dont think throwing bigger turbo's on the new gt500 would be that easy, where would the turbos be and how much space would be allotted for these new turbos?

Whipple is in development for a 4.0L supercharger that sits ontop of the current GT500's motor that makes over 900rwhp on pump gas. However, this kit requires a new hood which is easy enough to do, gives you more room. If the turbo's were in a not so easy to reach location, it might be a little harder to new ones on.

Whipple also has a 3.4L kit that does not require a new hood, just new motor mounts that lowers the engine a few inches, this kit makes just shy of 850 on pump

"The 4-vlave 5.0L V8 engine is expected to pump out approximately 400-hp with a maximum torque of 400 lb-ft."

I am dying to see how Ford is going to make an honest 400 lb-ft of torque out of 5 liters when GM's 6.0L doesn't and even Toyota's long-stroke 5.7L 4v makes that amount... . I am guessing they are going to rate it like the old Cobra 4.6 or Mazda engines... .

Point.

Even if it's slightly overrated though, ~400hp in a stock GT will be totally monstrous. The idea of cheaply and easily modding a GT to ~500hp without a power adder is pretty crazy.

I read about the Road Runner engine a few days ago. Completely awesome if true, but a strange rumor to hear when the word has already been long circulating that the GT500 will go to an aluminum version of the current 5.4L motor within a year or so.

didnt ford put something out that said they wanted to replace all the V8's in trucks and cars with turbo'd V6's? it probably has something to do with that, and the whole saving gas thing...

No. They tout the Ecoboost as providing V8 performance with better fuel economy, and they probably will use it to replace the V8s in several models. V8's in trucks and Mustangs are not going anywhere for the foreseeable future; I'd say the next 15 to 20 years, if not more, guaranteed. 20 years from now the F-150 might be powered by a turbo 4L hybrid V8 with ion-gas injection, but I practically guarantee you it will still have a V8 option available.

It can be argued that the Ford use of the name is referring to an engine and not a vehicle. Different companies can use the same name, especially if it is a generic name/word, for their products as long as consumer can diffrientiate (sp?) the two products and that the products don't compete in the same category.

"Road Runner" is the code name. That doesn't mean the Cobra will carry this name to the market.

I have no doubt about them being able to make a 400hp 5.0L for the Mustang--which would be a very sweet package, I am specifically referring to the 400 lb-ft of torque for the F150--no flipping way... .

I've seen one kit for the Camaro with twin turbo chargers at the back of the car so maybe that's an option for the GT500. Alleviates the heat issue with them being under the hood. Of course if you drive through a foot of water you sieze your engine...

Don't think they've released one yet (for the GT500).

And no, driving through water won't seize your engine. The kits come with a snorkel that's mounted way up in the back of the car, high above even the tailpipe.
