The 4.5 was also advertised to have this feature. This is probably the delay in the 4.5, making it reliable.
If the 4.5 comes out with this feature in the F-150s, it will be able with a predator, to produce more power than the 6.0.

i have always read and my experience w/ turbo diesels proves to me, a stock or VERY slight cam is where the POWER is at. once u start getting up in duration, u start gettin overlap unless u stretch the lobe angle. the more overlap u have, the less effective the turbo is, making u spin much higher rpm's. wide LA's are no good either.
get the stock style cam, and if u want more power, turn the boost screw!!! thats why we have turbo's in the first place, right?
for ex. i am building a 514ci caddy V8 that has two turbos. it burns gas from the primary's and methanol through the secondarys. ross pistons, H-beam rods, o-ringed block,
anyway, it is in the range of 1200-1400hp and 1700lbs of tq! but the cam has LESS duration than stock!!!

He regurally beats the Chevy nitrous mountain motors.

I am going to go with the stock cam duration. These trucks have insanely wide powerbands for a diesel to begin with, not much need to make it even more. What effect will increased lift have? Better breathing?

if u want better breathing, just turn up the boost
more press=more air=more fuel=more power....fun stuff
i love turbos!!!!

but u are very right about the heart of the engine. "power is made in the heads" a wise man once told me. he was right

Well, I would turn the boost up. But the problem is that two turbos wont put out more than 120 lbs of boost. It will already be running at that. The only thing past that for power (or getting air for the power) is valvetrain. Nobody makes a tri-turbo kit yet
I just want something that gets lots of torque, gets it quick, and carries it to redline. That is my goal.
Oh, dont worry bout that. Im getting a new fuel pump too
