2013 GT500 - 9.95 @ 142mph

[91CoupeMike]

Nah, the 2013 GT500 engine is a heavily modified 2012 GT500 engine... it retains the same 5.4L heads with some small modifications, it's the same 5.4L block with bigger pistons and spray bores. There's lots of expensive engineering tweaks, but it's still a bored-out 5.4L.

The Coyote is a totally different design.

Yes I know this.

What I was saying, not that it's possible but to take 6.2l displacement from the new 6.2 SOHC and somehow throw dohc coyote style heads on it.. Pretty much just make a larger displacement coyote engine w/ a tvs.

Put it in a new ford GT.. !

[DON SVO]

Yes Aka 5.8L.

It's not the new 6.2L if that's what you mean.

Bored 5.4L with GT supercar heads.

What you smoking don? Lol

[DON SVO]

What?

2013 gt500 = 5.8l Well it's acually a 5.9 but...

Get in the zone......

You do know this isn't a new 5.8L, right?

How much more power does a 6.0ls make over a 5.7ls? Or a 302 vs 331?

The ls9 is a bad bitch, but so is fords new 5.8.

The Cobra has 4 valve heads and a 800rpm higher redline.

I do wonder what the 6.2 would do with a 2.3 TVS blower? Oh wait, GM already knows. It's 638 SAE rated horsepower at 10.5psi on the ZR1.

Does anyone think the LS9 couldn't crank out more than 662 SAE rated horsepower at 15psi like the GT500 is running? Me thinks an extra 4.5 psi would generate more than 24 horsepower, quite a bit more. So, that really begs the question on why the GT500 doesn't make more than 662 with it's 7,000rpm redline and 4 valve heads, etc. Does, the extra .4 of displacement make that big of a difference even with a pushrod 16 valve set-up?

If-if-if-if ford used a modified coyote head on thier current 6.2l truck engine and put a blower on it, how much power do you think it would make? I think a lot.

Not that this holds any weight, but I was reading an article in a truck magazine, it was the raptor engine (6.2l) vs the silverado (6.2l). Bone stock the ford made more power and torque by a conserible amount and it made the power lower in the rpm range.. So they put the same supercharger kit (centrifugal) on each truck, same boost ect.. And fords made a retarded amount more power them the GM, something like 50+ hp and Torque.. And that's ford SOHC, I wonder what It would do with DOHC VVT?

GM 6.2l is a nasty motor, OCII proved that to me in the "FRIDGE" for headers and a tune + w/e else it was moving for a big heavy pick up.

How is our old friend Drew doing...

Not quite. I only took a few years of thermo to get my degree.

Andrew considers thermodynamics, "some light reading before bed".

drew:" i was bored last night.. so i read the internet.... all of it... and then spent this morning firing out emails correcting everyone.. this one idiot... steven hawkings or something had his theory of worm holes and space time all wrong..."

sup andrew.. whats shakin?

Neither car was a max effort production. Compromises exist in both.
In this case, Ford's compromised bar is just higher than Chevy's.



According to the laws of thermodynamics, it does. It's not as critical in an FI application, but the effect is still mathematically significant.

Please elaborate on my ignorant comments. Please show me where ANYTHING I said is not accurate.

I look forward to reading your enlightened word, oh great one.

LOL I'll just let someone else do it for me

You sure do like making blatantly ignorant comments.
