In recent months, rumors have been rampant that the next generation of Ford's Shelby GT500 Mustang would dump the existing 5.4-liter supercharged V8 in favor of a twin-turbo version of the new 5.0-liter Coyote V8 that debuts this spring. Unfortunately, in spite of earlier reports confirming the development, it appears that such an engine will not be installed in the GT500 any time soon. Autoblog had the chance to talk with Mike Harrison, Ford's chief engineer for the 5.0-liter and 6.2-liter V8 engines this morning, and he made it clear that the mooted engine is not part of the program for the Blue Oval bomber.

Harrison explained that such a configuration would be almost impossible for Ford to engineer because the 5.0-liter already consumes virtually the entire engine compartment. There is evidently no room to mount the turbos on the outside of the block where the exhaust currently resides. One possibility would be to put the turbos in the valley of the block similar to the new 6.7-liter diesel or BMW's 4.4-liter twin-turbo V8, but this creates a bunch of new problems as well. The heat generated by having the turbos up top would probably cause the paint on the hood to bubble and peel unless Ford could add some exotic and undoubtedly expensive heat shielding, which is unlikely to happen.

The other issue is that this configuration would really only work if the intake and exhaust flow were reversed, putting the exhaust in the valley. Without this change, the paths from the exhaust ports to the turbos would be too long, resulting in excess turbo lag and unacceptable performance. However, this would require a level of engineering investment for new heads that Ford is unlikely to make in such a low-volume program. Thus, we'll have to be satisfied with the aluminum block 5.4 that is arriving later this year.

Looks like those rumors are killed.

interesting

Yeah...been around for a bit on the Mustang sites. But the rumor's now are that Shelby may introduce a similar tech with their rumored GT350, base off the 5.0 engine.

Guess we will see come the 18th or so.

That car really does look nice...I think it's the wheels that really do it for me...

Anyways, this is interesting...I don't visit Mustang sites, and I heard those rumors a lot, too. It makes sense not to do it, though, based on the reasons above.

Actually, it sounds like the same reasons GM didn't put turbochargers into the ZR1...testing created "thermal events".

I always thought the rumor for the twin turbos GT500 would be for the 2012 year. Not for 2011. I think that Ford will wait and see if GM introduces the Z28 before they come out with a completely new GT500 engine. 2011 GT500 engine is the same as the 2010 except it has an aluminum block.

The article explained it in a way that makes me think it won't be in there during any MY. I agree though, they'll wait on the Z/28 so they can see what GM brings to the table in that segment.

I bet $100 they place a TVS 1900 supercharger on top of the 5.0 and Forge the internals.

It doesn't need it anyway .. lets keep the low end grunt ... I'd really like to see them do a 6 - 6.2L supercharged engine from the factory .. 575 - 600 hp

.... that would be great ... however what it has now 5.4L or even if they put in the aluminum block to save some weight .. it rocks either way.

And I would bet $100 that you are partially correct.

A friend of ours is looking at a slightly wrecked GT500 on a site. If the bid doesn't go over $25,000K for it, then I'll take it and fix it myself.
