2013 GT500 Engine Article in 5.0 Magazine

[Stinger1982]

Is now online!

A great read. This engine will seriously go down in history. I have never driven a street car with this much low end torque, and the pull never stops all the way to 7,000rpm. The acceleration is simply ferocious.

holy cow! are those 6 bolt mains!!!???

 

[sofa king]

Nice!

 

[CMYZ28]

Skimmed thru and didn't see it, what's the compression ratio on the engine?

 

[robvas]

6 more lbs of boost to get the 12 hp it needed to beat the Corvette?

 

[webleedorange619]

Skimmed thru and didn't see it, what's the compression ratio on the engine?

9.0:1

 

[webleedorange619]

in all seriousness this thing is insane, all aluminum, 9:1 CR, TVS blower, 5.8L, AWESOME! I will love to see what these things do with more boost.

"
...what is essentially a rotating arc welder is inserted into the cylinder. It uses a wire feed, an electric arc, and compressed air to blast a stream of 35,000-degree iron plasma onto the cylinder walls. The molten iron droplets are tiny, just 20 to 30 microns (0.0008 to 0.0011 inch) in diameter, and they dry in 10 to the -6 seconds. The wire-fed plasma jet is maneuvered to form a lattice pattern; later the cylinder is diamond-honed for final crosshatching..."

When did Ford start building space shuttles? That's some crazy technology!

 

[saleenjames]

i cant wait to drive one of these

 

[Stinger1982]

i cant wait to drive one of these

I can tell you its a rush

"cast iron manifolds" for exhaust.... I understand its got to be cost effective for production but come on! Put some decent tubular headers on it! none the less its totally baddass

They wont meet durability or emission on this application. Its not a cost decision.

We have had 6 bolt mains in DOHC (4v) V-8's at Ford since 1993!!!!!!

Then much later 6 bot mains were brought over onto 2v and 3v motors as well

i can understand the emissions part but durability i strongly disagree with as would any person to own a ford 4.6 or 5.4 with cast manifolds that will certainly crack and deteriorate. Like I said, its not a huge downer because 99% of people whom buy the car will swap them out pretty quick, I just hate ford for there crap manifold designs on some of there engines

 

[abazababalla]

hell yeah!

these manifolds are SVT specific. These are the only option that passed OEM durability.

I heard a *rumor* that a 30-40hp bump from long tubes and no cats wouldn't be and un reasonable estimate

More wheelspin. lol

I find this easy to believe
