Tick tock, tick tock.
Twins would be a first by an American manufacturer for a premium v8 model.
It would be as impressive as AMG's and BMW M's v8 tt's. If they manage 725hp, it would be exceptional. It doesn't need to compete with the demon.
Ford has offered an 8 second cobra jet for 5+ years now. You can put street tags on it with a few tweaks. This isn't saying dodge didn't do great, it's saying don't get caught up in the marketing. People have already made street legal cobra jets.
You stated that 15+ mustang 5.0 motors with aftermarket blowers are making 800rwhp with no issues.
I'm stating Ford can't do this based on what I stated above. The aftermarket does not have EPA rules or liability issues to pay for when things go wrong.
Yes the 5.0 with blower or twins will be a hell of a beast. But the fact remains the aftermarket will always put down more power.
I don't know about the Mercs, but BMW's ttV8s have some fierce turbo lag off idle. Then the boost hits way too hard, and breaks the rear loose. I've experienced it on track.
A turbo V8 Mustang would certainly be "interesting," but the power delivery wouldn't be anywhere near as linear as with a PD blower. That said, I think I'd be fine with either one. I'd prefer some snails just for a change, though.

The 15+ Coyote motors are extremely strong and will take 7-800whp without flexing.... roughly the same as a 5.4/5.8. There are actually several examples of 15+ motors taking 900+ on the dyno. Guys have gone 150+ mph in the 1/4. The motors are stout and bad ass.
11-14 coyotes had inferior rods and were only good for about 700 max before they'd wobble.
The 5.4/5.8 is old tech. Heads dont flow as good, vavles are too small, ECU capability is not as strong as the Copperhead in the Coyotes, no adjustable vavle timing... the list goes on and on.
The new GT500 WILL have Ford's latest tech and you can bet it will be some Coyote variant of a motor.
I know aftermarket Coyotes can put down huge power numbers, and I have little concern with a SC or TT 5.0 or 5.2 durability-wise. However, I do have a concern with the amount of power you can ultimately get on pump gas while passing all of Ford's long term and worst-case-scenario testing.
Let's face it, you can only put so much heat and pressure on pump gas before it detonates. That is ultimately going to be your limiting factor. The demon makes 840 hp on race gas, but only 808 on pump gas, and that's with a 6.2L. Getting the same or more air and fuel pumped through a SC 5.0 or 5.2 requires even more cylinder pressure. I'm not sure gasoline can take it.
Direct Injection will help (extend what can be done on pump gas before detonating). Higher RPM will allow a higher peak hp number, but ultimately I believe Turbos will be the magic bullet that is needed. It takes over 200hp to drive a PD blower at these power levels. Turbos will require much less. So while the Demon will have to make over 1000 hp in order to net 800 (due to the parasitic loss from the SC), a turbo engine would only have to make 875 or so to net the same output. This would allow the smaller 5.0-5.2 to run cylinder pressures similar to the Demon (and below pump gas thresholds) and still net similar power output.
Now I'm a PD blower guy. I love them. They are my favorite power adder and my first choice 100% of the time. I hope the next FPV Mustang has one, but if it's 840+ hp you're after while being OEM level bad-gas safe, I believe you'll need either turbos or more cubes...and Ford doesn't have any performance-ready offering in the stable with more cubes unless they I make a tall deck Coyote (a la the 5.4 version of the 4.6). I just don't see that happening, but I'm a pessimist.
Sure they make a little power, however to sell, pass all green regulations, and warranty it all without losing your ass takes more than putting a blower on a 5.0 at 700rwhp and hope it last 10k miles.
Fords own pass/fail test on all its motors are 300 hours straight many of those hours(more than half) at wot.
Show me one of these aftermarket blown 5.0 motors that can pass this at the same time passing EPA regs.
Good post!
Your first rebut to my post was something about how Ford puts their motors through 300 hours of full throttle tests and that the FI Coyote wouldnt last.
Now you are talking about smog, EPA, and profitability? Da fug???
Nice move on the bait and switch.
how do you make it street legal with no VIN?View attachment 88651 Let's avoid the bs retorts that I must be mistaken before they start.
Carry on.
