very nice

"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

Ford knows what they are doing with their ugly cast iron manifolds. I had a nice pretty set of headers on the GT, switched back to the ugly cast iron manifolds and even though the peak torque only went up a bit (something like 20 rwtq to 740 rwtq) it picked up fucking 200 rwtq at 4k rpm.

But why does the cast iron work better? is it for holding the heat better? just seems like tubular would be so much better..

The dudes that do most of the work on my car both worked on the GT during development, and they said that those engines always seemed to like back pressure. I'm not smart enough to hypothesize any other answer. :lol:

I can tell you its a rush

x2. It is insane...

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

That's the same technology they have been using to make the 5.0 since it was released in 2011.

They didn't use the plasma arc coating on the 5.0, it was only on the aluminum 5.4 motor and now the 5.8. Nissan also uses it on the GT-R motors.

Its a helluva motor not gonna argue that one, but we still have the LS9....just sayin =)
I wouldnt buy one, and thats my preference, but i sure as shit would own one lol...
Ive been wanting a ZL1 since the 5th gen came out,..back in 09, but i feel that this car will eat it up...

You need heat to light the cats off for start up emissions.. The regulations are so low now that 80% of the emissions test is determined in the first 100 seconds.. Yes I'm sure long tubes would make more power but keep in mind there are test that need to be passed otherwise there is no certification on the vehicle and no vehicle to be sold..

Makes sense and I kind of figured it had to be due to emissions. I doubt the durability part, like i said fords cast manifolds are notorious for being junk, ask me because every vehicle i have i had to replace them.

AMAZING stuff!

Crazy to believe all the engineering that goes into stuff like this and at the end of the day, most of the customer's don't even know it.

Working on that team would be my dream job......

Ya thats right, I goofed. So they started doing the plasma arc in the 2010 Shelby??

No, the 2011 Shelby. The 2010 still used the iron 5.4 block. The 2011-on use the aluminum block with the PWTC coating inside.

Ford has been playing around with this since the early 2K's. Some of the early issues were long-term adhesion and masking of areas where you DON'T want this stuff. (It's pretty hard to keep micron-sized balls of molten iron out with masking tape!!) The technology has migrated to re-manufactured diesel engines. They spray cylinders, mains, and block deck faces, then machine everything back to std. It works!
