2020 GT500 Will Be Revealed on Jan 14, 2019! Sneak Peek of Supercharged 5.2-Liter Predator Engine

[Stuntman]

I'm not debating any of your points. I think you are right with all of them.

I just don't think Ford would have to rev a blown 5.2 out to 7,500 to achieve their power goals. And the engine will last longer with a lower red line. Aftermarket applications don't have such a long warranty, so for Ford reliability is a very high priority.

What I was trying to say is that in an NA application if you are limited on displacement and want to make more power, you need to increase the engine's capability to breathe and rev to a higher RPM in order to make power. A simple way of thinking about this is the engine can behave as though it is twice as big from a power standpoint at 7,000 RPM versus 3,500 RPM.

So for the Coyote the revs are more important, because it is NA and the displacement is still limited to around 5 liters. The Predator will probably achieve the goal HP easily with a 6,500 or 7,000 rpm limit. I don't know whether Ford will lower the red line of the Predator compared to the Coyote, but if they do - it's a possible explanation or some reasons why.

Most forced induction engines have lower redlines than their NA counterparts (Porsche, Ferrari, Chevy, Ford). I don't think this car would be any different. The old 500 had a 6,250rpm redline with a brief 7,000rpm limit. It would be nice if this car could hit 7,000rpm all the time.

How can Ford say this will be the most powerful engine we have ever had IF the placard is correct at 650+ horsepower shown? wasn't the 11-14 Shelby GT 500 rated at 662 hp? Or is it because this is not considered a Shelby.

Because some marketing jackass at Ford thought it would be cute to put "650" on the placard that may have been a shot at the ZL1 Camaro but only served to confuse those that didn't know that Ford hired jackasses that make decisions that create ambiguity?

Wow, you missed a comma.

Lol

 

[Epiphany]

Even some in the media are now confused. Jackass decision there FoMoCo...

Truth. I can't tell you how frustrating marketing is from engineering's perspective in the auto world.

you're telling me nobody else saw the discrepancy in power figures at this event and raised the question to the organizers? No way this just slipped through.

 

[Dusten]

It's not a discrepancy. It says more than 650hp.... 780 is more.

 

[Kong76]

To me when they say 650+ I would lean towards maybe 25-35 more hp. I believe it needs to be around 750-780. Thats the game on area to me as well.

It is when their first reveal video said over 700. Either way none to worry, just wondering what bonehead put that there.

 

[Stuntman]

705hp, 4,300lbs, 10spd auto, overheats in 2 laps. I sure hope not.

That would be a disappointment but I don’t see that happening. Any new word on the DCT?

I guess you are a "glass is half empty" kind of guy

It would seem that Tremec (and anyone else in the corporate chain that knows) has reason to be extremely tight lipped. News on DCT development and production at the new Wixom plant has been nonexistent, understandable what with potential Corvette and GT500 DCT's coming down the pike. Sooner or later the dam will burst and my only hope is that we learn the real story behind what drove Ford to make some of the choices they did with this car.

Yeah, I'm hoping for: 775hp, 3915lbs, 7-spd DCT, laps all day with 10+ coolers ... oh yeah, and a FGT type DSSV setup
