Here are the Raptor engine specs...

Oh well then... What's the hp?

It's been "leaked" by Raj Nair that the hp number is 450.

This one day, at band camp

So do we have enough threads about this already? Yeah, I talked go someone at Snoball that worked at Ford and they told me to wait until 2018 when the new V8 is released. We all know someone, right. Here is an idea, why not wait until we hear it from the horse's mouth, FORD when its official. Otherwise, meanwhile at band camp.......

If the hp is 450 then the tq. is going to likely be over 500 lb. ft.

 

[Hockster]

My Ford sources tell me they are breaking their backs to make sure its 505 TQ. They want it above that 500 mark

Those numbers don't make sense to me. Only 30 lb-ft more torque than the standard F150, but HP is up by 75?

That's backwards. The new 3.5 gained 10 HP with a 50 lb-ft increase in torque in the standard version. Pumping in another 30 lb-ft shouldn't make the HP suddenly pop like that.

The Raptor will have a higher redline, but max HP on a turbo will be lower in the rev range so that shouldn't matter.

Am I missing something here? 450/550 would be a more reasonable ratio.

Remember the raptor has larger turbos (probably not by a whole lot), theoretically that equates to more air flow on the top end. I have no clue what the dyno plot of the gen 2 standard ecoboost will look like, but if it's anything like the current gen, it'll produce great torque over it's rev band but will be falling off on the top end. It's entirely possible (and normal) to pick up more HP than torque with a turbo size upgrade.

If you look at other ford turbo vehicles stock vs tuned, you generally see a nice torque bump but not so much in HP. In most of the cases that I've seen, it's because they tend to use a smaller turbo for fast spool to begin with. The tune bumps up pressure in the lower end of the rev range and you get huge torque gains down low. And while there is generally a nice bump in HP too, you can't create more flow than the turbo is capable of on the high end... no matter what you do with the waste gate.

You have to remember that ford has a lot of flexibility with modern turbo engine. In pretty much all cases, they purposely tune the vehicles to have a flat(ish) torque curve. Most manufacturers do this.... and most tunes "un-do" this to some degree. Manufacturers let the turbo spool, then limit boost pressure by bleeding pressure via the waste gate, then let the turbo open up at the top end (bleeding less pressure). That gives you a flatter curve then if you just let the turbo do it's thing with no boost control.

We better get this thread password protected with all this top secret discussion...

With the electronically controlled waste gates on the new motor, they could very well be limiting boost (and therefore peak torque) down low stay within the designed capacity of some part of the engine or drivetrain. That could account for what seems to be a low peak torque number in relation to the peak power output.

Agree - see my other post on extending the boost higher into the revs. I'd wondered why the big exhaust, but it may be all about eliminating back pressure at high RPM to keep the boost going.

From Ford's perspective, that would be nice, since they get a big HP number without increasing the boost pressure all that much. Better reliability but keeping the bragging rights.

And it should still have plenty of drivable torque with the 470 to 500 bump, which I'm sure would be across a wide RPM band. If the turbos are too fat though, lag could be a problem.

I wouldnt worry too much about lag, the current EB makes max torque at 2,500rpms which is pretty decent.

Lag? What lag...lol

I'll be joking about this for years to come. Cant believe I'll have a truck that has a baja mode
