isn't running all that boost and having the comp not know it bad? I know as far as gas motors go its crutial to up fuel in times of higher boost.. what is teh difference for diesels? I know the mechanics of the engine, as I am a mechanical engineer, but why can you up boost w\o more fuel and or not breaking things

You have to let go of that gasser theory. You are correct in gasser worlds, the most dangerous situation is too lean, that is why fuel has to be upped with more boost.

Diesels however accelerate by adding FUEL not air, therefore they need AIR AIR and more AIR. You could say there's really no such thing as 'too lean' with a diesel.

That it's not a major concern to the engine at elevated boost levels. It is set the defuel by the stock MAP limits is for performance/detuning and emissions reasons.

Re: Banks Big Head Actuator

Greg gave ya the link there. You'll need it, yes, if you add the Big Head... unless you grandma drive it all the time. [img]/ubbthreads/images/graemlins/wink.gif[/img]

02Powerstroke, the main issue with higher boost numbers is that past around 25-27 psi the stock turbo gets outside its efficiency range, and compressing the air further than that just generates excessive heat and not much more helpful dense air. Over time the heat can damage the turbo. From what I understand, adding an ATS housing to the stocker bumps the efficiency line up some, so you can run up higher than 25 psi and still be creating efficient boost.

As for damaging the engine... well, there's a truck belonging to Wide Open Performance with compound turbos, makes up to around 100 psi from what I understand... on the STOCK PCM: no programming of any kind... yet. [img]/ubbthreads/images/graemlins/cool.gif[/img]

You don't need programming if you have huge injectors that spray a ton of fuel at stock pulsewidth. In fact, I've heard of instances where jody has basically built programs that less pulsewidth than stock to get better control of high flow injectors.

Re: Banks Big Head Actuator

Hammer, does Zane's truck already have huge injectors?

edit - that's a silly question... it must! [img]/ubbthreads/images/graemlins/cool.gif[/img]

Re: Banks Big Head Actuator

Woopsie... yeah, there's those small details that should be mentioned. [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

But with the Big Head, we're generally talking 25-32 psi.... not 100. [img]/ubbthreads/images/graemlins/smirk.gif[/img] [img]/ubbthreads/images/graemlins/blush.gif[/img]

Re: Banks Big Head Actuator

Some report good luck adjusting the OE waste gate tighter 3 to 6 turns. Some report breaking the rod while trying.
For a stock truck IMO put your $$$ elsewhere.

Re: Banks Big Head Actuator
