Tons of headroom

[Charles S]

While waiting for my spray in liner to be finished at the dealer I came across this Ford Frontline magazine which states that the turbos in the Raptor are only pushing 13.2 pounds of boost. If this is the case there is a ton of tuning potential.

As long as fuel injector IDC is available this will be fun.

Inaccurate info from Ford. The regular 3.5 ecoboost in the F-150 is boosted to 16psi. The Raptor is 18psi, published in many auto journalism sources.
First, the K04 turbo it uses would be totally wrong for an OEM application that only wanted 13psi. They simply would have used a different turbo housing.
Second, you really think there is something so magical about the Raptor 3.5 that allows it to produce way more power and torque than the regular 3.5 truck engine while boosting less?
There is some headroom in the stock turbo setup, enough to boost to 21-23 psi peak but no more than that given the limitations of the KO4. The real questions are going to be if the 10-speed gearbox can hold the torque and if the stock fueling can support that boost level.

Have we confirmed the turbos to be K04's

Nobody has confirmed it yet but I would put money down on it. We know they are Borg Warner. We know BW's product line. We know that a Ford Raptor is a mass-produced, relatively cheap vehicle. This is not some exotic bespoke turbo made by BW to satisfy some unusual criteria. Ford engineers phoned BW's engineers and said "We need a turbo for a 3.5L V6 that can make around 18, maybe 19psi reliably."
Now the Ford GT is likely going to have some more exotic hardware on its 600+ bhp 3.5. And as well it should for $400K.
But you are right, it has not been definitively confirmed as yet. Ford is really weird about disclosing some things.

The transmission is a 10R80

10= 10 speeds
R = rear wheel drive applications
80 = 800 N-m nominal max input torque capacity

yah... think there is plenty of headroom capacity

If that is the case, we may see some issues with the trans. 800nm is only 590 lb-ft of torque. Tuners may have to limit boost as a result.
Much has been made of the fact that this trans is a joint GM/Ford effort and that some version of this gearbox is in the new Camaro ZL1 which makes 650hp and 650 lb-ft from its 6.2L LT4. I wonder if the trans is the same or if the GM version is strengthened in some way?
What of the transmissions in these modded Super Duty trucks? What is their factory "rating" vs what they are reliably holding once modified? Maybe Ford slapped an 800nm rating on it sort of arbitrarily as that is the upper limit of what they have planned for it while it can actually hold quite a bit more.

10R80 = 10 speed & 800lb/ft not Nm.

 

[combatninja]

800 lb-ft you say? That'll do nicely then.

Sport mode, WOT. Boost gauge shows 18 psi.
