Dead Pedal revisted 2013+

[TCDiesel]

I don't push intakes ,But I think this requires some discussion, My 2013 does not have the dead Pedal that some owners have mentioned. It scoots pretty good.
I installed the Banks Intake for 2013+ and found what I believe to be part of the lag/dead Pedal problem. Banks intake does away with the warm air intake gate entirely and only partially blocks the cold air intake. My lag improved after installing the intake.

My guess is the operation of these to gates are some of the issues, they (May) partially be restricting the air flow and communications ,the cold intake port is small and if the gate is half way that may be restricting the air flow.

I will tell you this the Brake noise is considerably louder and you can hear the turbo with the Banks Intake. and there's more room to reach the oil filter from the fender liner Hey!

This is a very interesting observation. Is there a way to monitor the gate position under operation? it would be interesting to see if you could test a truck that has the dead pedal issue and monitor the gate position in real time.

 

[TCDiesel]

Knowing what I know Now , I would remove both gates (Or 1 at a time) run with that or put 1/2 holes threw them 1 at a time, the Banks intake, the entire hot side gate is not used.

I cannot remember seeing the option in WITECH monitor its position.

do you think the 388 bucks was worth the gain in either performance or happy turbo noise?
i miss the turbo noise a lot after driving my 2001 2500....
cheers!

 

[TCDiesel]

If you don't mind the increase Noise I think its worth it, And it does give more room to maneuver the filter out the wheel well.

Does that box retain the oem air filter?
It looks to be different in shape.

so if one is halfway open, the other is halfway open also...I don't see how that could cause a restriction.

Just went to Banks website...they have both dry and oiled filters...but the both look small...no way would I put that on my truck. JMHO

was thinking the same thing...

Yes but look at all the internal blockage at 1/2 Way or open closed.

 

[TCDiesel]

The filter is huge. The picture just makes it look small.

No.

I also think the sound tube is additional blockage. The entire OEM box/tube is design to suppress the noise the Brake and turbo make.... at the expense of Flow.

We flow test heads all the time and the results don't lie, any type of internal diversion has a big impact on the holes power.

And depending on the response rate of the door actuators, it certainly could cause a hesitation or the dead pedal feeling until the door position opens to the point to allow enough airflow for given condition.


Good theory and catch TC. I think you are on to something with this.

Keep up the good work.

That being the case.....restricted intake typically would reduce high rpm performance, when air demand is high, not off-idle performance.

Are we assuming the door actuator is constantly opening and closing with throttle position? That is not my understanding of how the Ram-Air box works.

I initially didnt think it worked thay way either. But, since they move, there is a very good posibility for them to be out of position based on demand.

As I asked earlier in this post, there doesn't seem to be a way to monitor door position via scan tool. If you could, you could see exactly how the doors operate based on throttle position, ambient temperature, ect. But that also leads to the question of are they actually opening when they are supposed to be open?

A really think there is some sound theory here. At least enough to continue testing along these lines.

WE can agree on this one for sure!!! Smoke and mirrors I say. Banks makes QUALITY products BUT their claims are far fetched. I have wasted several thousand dollars on two rigs that I could have gotten the same Performance at 1/2 the price,

 

[kthaxton]

My response would be that dead pedal is too consistent to be caused by occasional, coincidental scenarios when the air box valve happens to be in transition when the driver is getting on the throttle.

Can I prove my thought process is correct? No, I can't, but if I were a betting man I would say dead pedal is not related to the air box....further, I doubt the BD Throttle Booster would be partially effective if the air box was the issue. Dead pedal appears to be electronic in nature.

Its how quick you can build Boost, No boost = Lag

Kthaxton , I agree its a bunch of stuff = dead pedal/Lag. So start taking a bite at it better then Nothing at all?

Logic would dictate if it was all related to Tuning Ram would have made changes at some point?
