2018/19 Shelby GT500 Mustang Spotted! Twin Turbo V8 Powered? [UPDATED WITH VIDEO]

[thePill]

... or in Pillspeak, a Double Half Bi-Turbo Dual Quad Cylinder

In all honesty, I don't think an honest Cobra Jet Twin Turbo can be packaged under an S550.

i don't understand why anybody can think of anything Turbo related. Maybe one of you guys can elaborate? There is no indication in any of the Videos for that distinctive Turbo Sound?

Sounds like a Borla exhaust CPC V8 muted by turbos to me.

Pretty specific, eh? LOL

I don't think we need a MAch 1 to whoop the SS. Just a DI Coyote GT.

A Mach 1 would either replace the 350 or be a repurposed nameplate to take the GT500's spot if we aren't' getting the GT500 name.

You'd only hear it if he got on the gas and got off. The engine was barely putting in work. No boost.

alright, thanks for the info. Well then we have to keep guessing i suppose

So to continue with this rampant speculation. We all know the easiest way to increase power is to go with more displacement. That makes running a 5.0 or 5.2 somewhat of a longshot. Ford was already having problems running all of their extreme durability testing on the Trinity 5.8 due to the extreme heat causing issues with the exhaust valves, and it's rumored to be the reason there was no power pack for the 13-14 GT500s, it was already at the durability limit. I'd imagine that meant tuliping of the exhaust valves in their extreme testing. Again, Trinity did not meet all of Ford's extreme durability testing but the testing is so extreme it's unlikely the engine would ever see anything close to that for that many thousands of miles in the real world so the Trinity was given a pass on 1 of those tests. Add even more power and the problem would become worse.

We know Ford is gunning for 725 or more on this new one. We also know that running the 100mm bore spacing is a real handicap for increasing displacement and that Coyote doesn't have much more room for added stroke. Enter 115mm bore spacing. Ford could run 105mm bore with 84-mm stroke and get to 355.1 cubic inches (5.8 liters) AND get a block deck height down to around or just under 9-inches which is almost identical to the Coyote. For comparison the 5.4/5.8s in the 07-14 cars had a deck height over 10-inches. So this could decrease engine height by around just under 1-inch. It would be longer than the 5.4/5.8 by just under 2-inches but I don't think that's the real issue with the S550 chassis, the height is where the packaging issues arise (V6 intake clearance problem and resulting power decrease vs '14 V6).

And again with more room for coolant passages due to the increased bore spacing they could flow more fluid volume around those exhaust valves to remove more heat. Hell, even if they just stuck with the standard 6.2 architecture they'd still come in shorter than the 5.8 Trinity but I think it would serve them well to shorten the stroke and chop down the deck. It's not like they aren't already having aluminum V8 blocks custom poured at the foundry. Honsel poured the 5.8 and I read somewhere the 5.2 is poured at a foundry in Canada. So it's not really a cost issue. Roush already did work with them on Don Bowles's project DOHC 6.2 so they already prototyped 115-mm bore spacing DOHC heads years ago., which lessens the work required to design production heads now. The increased bore also gives them more space for head gasket surface area between cylinders, helpful on a 725-750 horse boosted V8.

I must have missed it. How do we know that?

Why would they settle for anything less than 707?

 

[Super Werty]

Why would they settle for anything less than 707?

Because it's doesn't weigh 4 billion pounds

Ford was very vocal about broadcasting how the Trinity was the world's most powerful production V8...I'm sure they'd like that title back from Dodge.

Then they better blow past 707 and 725 for that matter. I doubt it would take much for Dodge to squeeze another 19hp out of that Hellcat to quickly regain that crown.

The common sense question is why wouldn't they shoot for 750? A supercharged GT is in the 800HP range reliably. Look at all the publicity the Hellcat got. Why would you not top them?

They don't need more hp to beat a hellcat. They can do it with less and dominate in every class.

It's not about dominating a class. It's about selling cars. Dodge has received a nice little bump in Challenger sales thanks mostly to Hellcat publicity. Take the Camaros performance advantage over the GT this year. That hasn't translated to sales. And the SS is dominating the class!

 

[Voodooo]

A 2013/2014 GT500 vs hellcat stock for stock is a good race. The mustang has the weight advantage. If the next gt500 has 680+ hp the hellcat doesn't have a chance. The hellcat is to heavy.
