Have you seen their dyno chart? It shows the car on the stock tune making peak power at 5500RPM, then plunging immediately after that. There are so many weird things and weird claims about this that you’d have to be at least healthily skeptical. Even better, still no real world or third party...

^Those seem like massively inconvenient results. LOL

Not even close to what the power gain is from forced induction, and it’s similar to full bolt-on E85 cars we’ve already seen. There’s not going to be so much stress that the motor shouldn’t be able to make a few passes.

Again, where are you guys “hearing” this from, and where is the data you’re “digging on” to develop your opinions? That’s all I’m asking for.

What I’m saying is that we need more data. A 15.25% power gain, practically throughout the entire power curve to boot, with only a tune on good pump gas is extremely unlikely. It seems to me that I’m being healthily skeptical, willing to admit that it’s true with some data, and many people here...

Please, do share the details. Link?

Forget the whp versus bhp debate, just figure it on a percentage. They gained 15.25%. That percentage should translate pretty closely to most any corrected dyno figure, barring some kind of extreme conditions. Let’s take the example of 436whp given above. With their tune only, on let’s say 95...

For everyone trying to say maybe it’s the potential 1-2 extra octane AKI, just stop. E85 has been used to tune by others, and it’s equivalent to roughly 110-116 AKI. That said, I’d like to believe this as much as anyone, but it’s highly unlikely. If someone can convince them to send logged MAF...

Looks great, but does anyone know if they’ve updated the shift forks on the 2019 manuals yet? Considering that the Bullitt only comes in manual, that seems fairly important.

Checking in. Any new details?

So, are you estimating that your E85 pull would’ve read approximately 450-460 on this hub dyno? Just wondering about the ~10% figure you quoted.

That’s by far the highest stock 2015 SAE pull I’ve ever seen at RA, and the 2018 is still up 35whp/36wtq.

I know it’s not back to back, but RA has multiple dynos of stock 2015-2017 manuals using SAE correction. They’re right around the 375whp/350wtq range. The 2018 is definitely looking like more than 25bhp/20tq had been added versus the old motor. The power curve is much prettier too.

If not the exact intake manifold, I'm sure it will probably be similar to the GT350 manifold.

I'm guessing that they're going to have the GT350 intake, TB, and CAI now. The power from that, plus the increase from 11:1 to 12:1 compression should bump the GT to the advertised 7500RPM redline and bring power into the 470-480 range with more low end power than before. I voted 475 since it's...

With the little bit of info out there for the 2018 5.0 upgrades, I'm guessing that they're going to have the GT350 intake, TB, and CAI now. The power from that, plus the increase from 11:1 to 12:1 compression should bump the GT to the advertised 7500RPM redline and bring power into the 470-480...

The new fuel system would help with that. Cylinder cooling is one of the main advantages to using direct injection. Even if the CR stayed at 12:1, I think DI would give them an opportunity to tune more aggressively. I really hope Ford uses this engine for more than three years after all that...

I think what they said was that direct injection rather than port injection didn't offer enough pros over cons in a naturally aspirated engine. With a combination style injection system though, that's addressed. They will already have the hardware for it because of the 2018 Mustang GT too...

Does anyone think that the Voodoo will follow the Coyote path next year, and gain the direct injection/port injection combo with a bump in compression? A 13:1 or 14:1 compression ratio could be feasible with the new fuel system. Maybe 550+ stock horsepower with better low end.

Looks like a catted header system was tested there. The baseline was stock with stock tune.
