I have reworked my intake on my 99 F150 with the 5.4 engine. Really liked what that did for waking the truck up and all. I removed the plastic parts that narrowed down the air intake track before the air filter. The question I have is this, my biz partner has a 2001 Ford truck that has the V10 in it.
Would his truck benifet by reworking the air intake. I don't know if his engine has three valves per cylinder or not. I understand that engine with 3 valve must be retuned when doing this work.
Thanks

 

His is 2

 

So you came up with a crappy version of the Gotts intake mod?

 

wait till summer time and the performance decrease

 

All you did was remove the part that reduces intake noise.

 

I left the air intake intact--I removed the parts inside that narrowed the hose from 3 inches to 2 inches. There were two parts. One snaped out and the other, I used a dremel tool to remove. All of this was in the tech articles from the top of the page on this Forum. As for waiting until it gets hot and the summer heat hits--I'm not seeing what this would have any thing to do with how this was done. If I were to gut the air box and allow the air to come into the engine from under the hood--that would indeed be a bad move. But the way this was done, there's nothing but air from out side of the truck going to the engine.

 

I thought you had chopped the air box apart

 

Swiss cheese air box mod?

Reminded me of a family member who is a vw diehard. Somewhere on the vwvortex forums there is a "how to" drill 1" holes in your air box with claims of 3+hp and a "tuned sound" They call it the swiss cheese air box mod or "VW MKIII VR6 swiss cheese air box mod" Sounds cool huh

 

kinda like that

 

So on my freinds F150 witht he V10--does that truck have the same obstruction in the air intake as mine?
Thanks

 

If I am reading this right, you removed the snorkel part that resticts the intake and goes into the inside fender well and then used the existing filter and housing in place without the snorkel to collect air direct from the engine compartment. I was thinking of doing the same thing, it should have even slightly less airflow restriction (friction) of the full GOTTS mod.

I am in Colorado at high elevation and am wondering if this might be a good way to go during the winter months when it is very cold outside and the engine is running colder anyway, and then install the PVC part in the summer (full GOTTS mod) to collect air from the fender well when the outside temps are hotter. I guess, the question is: is there an optimal air intake temperature that my 5.4 would prefer, or is colder air always better, regardless of how cold it is outside?

I wonder what the alaska and Canada crowd likes? Hope I am not highjacking the post, but my concern seems related, newbie here, thanks

 

To be frank i dont agree to this mod and to be frank again. ( i adore being frank) i think you should have just done the gotts mod. the reason is your going to be sucking in hot air from the engine. with the gotts mod however you will be getting outside air. a much better way to go

 

I am "Gotts" I live in Canada and have been running this year round for over 4 years now.

 

The whole stock system is already drawing outside air.
What's the deal?
The motor can't use anymore air no matter what is done.
Looking for more power and mileage just is not their.
The neck down fitting alarms many who see it as a restriction.
It's there to reduce intake noise for the greater number of owners.
If you do the math on circular area vs the needs of the motor in terms of CFM airflow, there is no restriction for truck use. Not in the hardware or the filter.
.
I'm sorry to keep going against the notion of improved performance but people are not using applied physics and just going by what some one else has done with no real proof it is an advantage for truck applications.
Maybe on a race intention but not on a street truck never runs much above 4000 rpm in the normal course of use.
Matter of fact the 5.4 motor uses the same filter as the 4.6.
Besides the throttle opening normally attained during normal driving most often is less than half.
This is where the restriction is to normally control the efficiency/power of the motor so what is done to increase the airflow ahead of the throttle body has no effect.
You have to remember the 4.6 is only a small displacement at 263 cu/inches so it's air needs are not that great.

 

OK, let me try again--I found the following write up in the tech listings and I thought it was a dang good deal, worked for me---
https://www.f150online.com/forums/ar...3-f-150-a.html
Now , if you check the above link out, you might find that , 1--I'm not destroying my intake system. 2--From what I'm seeing, this mod lets the air in with out restriction when the engine needs it--in the higher RPM levels.
This works fine for me, and I ain't a looking back--
What I'm trying to find out is, will this work for the Ford F150 trucks that have the big V10 cylinder engines. I don't want to tear into this and find that I have taken things apart that there isn't a need to do--hate it when that happens.
Thanks
