Well i am one of the fews guys that went ahead and did the bullbar that covers the front opening on the ecoboost.

Well i even know if the bullbar is coving too much and not letting enough air to the intercooler?

will there be any effects? milage? etc

 

warranty. someone here not too long ago found a clip and posted it concerning voiding the warranty if that area is blocked.

 

Ford can't void any warranty unless it it 100% conclusive that the modification caused a certain failure.

Any to answer the OP's question. The most that can happen is you'll have a little more heat soak. Meaning the turbo's will not perform as well being hot.... now, I personally question how much it would be effected. IMO, I don't think it will be that big of a deal. Air can still flows under the truck. And most people are not drag racing with their f150s(meaning the turbos shouldn't be working very hard under normal driving conditions). If you are towing often, I might think about not having that area blocked.

 

Actually heat soak is what happens when you shut the motor off quickly after some hard driving (high turbo use) and don't allow a minute or so to let the oil/coolant temps to drop. The high temps cause the oil that cools the turbo's bearing to cook a bit and is detrimental to the turbo. Newer systems are better at handling this.

Blocking any airflow to that intercooler can make a measurable difference. Heat kills the efficiency of the turbo. I used to take mine out and clean it every so often to maintain it. Blocking the airflow will not allow the intercooler to cool the compressed air that is being shoved into the intake, thus you will get less power AND the intake temps will be higher and you have more chance of some detonation. The computer will compensate for that heat and dial back timing and possibly boost which reduces power. Less power= heavier foot which leads to the vicious cycle to start all over!

Just my .02

 

Actually, I'm referring to intercooler heat soak.

Taken right from Garrett:

"What is intercooler heat soak?
Heat soak is when the intercooler can't dissipate the heat that it absorbs from the turbo fast enough. When an intercooler can't cool the charge air by removing the heat from it, it loses its effectiveness. This explains why turbo cars tend to run slower or have slightly less power when the weather is warm. "

 

Well then, my apologies sir!

Seriously though, I always just assumed there was one kind of heat soak!!

For the OP, both would be an issue I would think. Just be aware under heavy boost!!

 

All good.


My only solution that I can think of would be to add an aftermarket electric cooling fan to the IC.

Something like this:
