JCP1990S4

I noticed that the 2008 Mustang GT has similar performance specs to our cars. But it was pushed out of the 4.6 V8.

Now the new 5.0 even looks like our late model motors especially the first 86. Displacement almost identical.

Sweet motor! She would be fun to drve!

But I would rather have a 928!

The variable valve timing is the key to power and economy. Driving around at 1/4 throttle most of the time keeps the cam lobes very narrow. I'm pretty sure the duration is also altered when you put your foot down releasing the power.

GM took another approach with displacement on demand, by deactivating cylinders in economy mode.

Chrysler does that too, on the Charger V8's especially, shutting down half the engine and running on 4 cylinders for cruising.

too bad it will take ford about ten years to get the thing reliable..

Not just variable valve timing but even vast improvements in EFI also makes this happen. Refer to Megasquirt, Electromotive, etc 928s.

totally different engines.....the 928 is a "big block" with a short deck.....the 4.6 family Ford engines are a small block and shorter deck.....the 928 is a 122mm bore spacing with a 232mm deck...the 4.6L ford is 100mm bore with 227mm deck....the 5.4L retains the 100mm bore but with a taller 254mm deck required to make the displacement

How the 5.0L mustang engine makes its power its through its 11.0-1 CR and variable cam timing....that with modern engine controls allows for much more aggressive timing-fueling....

For reference....my 4.0L V8 in my M3 makes 414whp (closer to 450)..or 3 more than the 5.0L in the mustang..with 20% less displacement...

The 5.0 L (4951 cc, 302 cid)[9] "Coyote" V8 is the latest evolution of the Modular engine. It retains the 4.6 L's 100 mm (3.937 in) bore spacing and 227 mm (8.937 in) deck height while bore diameter and stroke have increased to 92.2mm (3.629 in) and 92.7mm (3.650 in), respectively. Compression ratio is 11.0:1, despite having typical port fuel injection (as opposed to direct injection) the engine can still be run on 87 octane gasoline.

that is a nice looking engine, good output too. nice to see a serious performer mustang.

IT NEEDS AVAILABLE IRS

V2Rocket

the supercharged version of this thing will be insane, even on just 91 pump!

goodspeed928

30 YEARS! I think it should have 550hp

hacker-pschorr

So should every 928

Richter12x2

Cobras of each year typically get this.

What makes you say that?

They seem to reliable enough to be out selling GM and Chrysler, and Obama couldn't jam the bail-out funds down their throats either.

my buddies 01 cobra cam chains went at 31k, head gasket at 35k, and then two weeks later snapped a rod.... the thing was bone stock never beet on

I can second the craptastic quality of early 2000 mustangs. One of my coworkers owned one and was modifying it for more boost. At something like 400rwhp, one of the half-shafts snapped.
