The kd4crs/Power Hungry/Gotts Mod (revisited - and with pictures)

Jim, I'm certain Bill did not use the AgentOrange design. That's a pretty unique idea I think!

I'm fairly certain it was of the kd4crs ilk, or maybe even just an open tube minus the bellows and snorkel.

I wish I could take full credit for the idea, but Banks beat me to it.
If you notice, his design also uses the fenderwell inlet.

Check it out: http://bankspower.com/products/show/32/50 lot's of info there.

I doubt my mod makes the power his does, especially because I am still using the stock filter, but the principal is the same.
I think the main point of this and the kd4crs mod is to allow the engine to get as much air as it may need and keep it as cool as possible...plus, I just like to tinker with things.

Just my .02.

I did this mod on my 08' 4.6, it was quite different since it uses the cone style filter, the PVC pipe is about 4 or 5 inches long.

I will post a picture of it when I get a chance if wanted.

Post it, I haven't seen the new style yet.

Not mine but with the mod the only difference is where it meets the fender all you can see is the PVC pipe coupler I will get a pic of mine up later

The 04-08 F150s with the 4.6 engine have a different intake and filter arrangement. It also has a snorkel tip that goes into the fender hole so it can be removed and replaced with a straight pipe similar to the DWV intake mod for the 5.4L engine. I think there is also a silencer insert in the intake tube downstream of the filter housing that some folks have removed to improve flow and add a ponies.

EDIT to add: It looks like the 08 pictured above has a different style intake than the 05 with the 4.6 that I looked at regarding the silencer removal. See the link below:

Yeah I didn't look at the other part of the intake, it looks all straight through, does that extra part on the front really matter? I just replaced the snorkel with 3 inch PVC, and I even bought black paint to paint the PVC cause I couldn't find black PVC but you can't even see the PVC since the coupler covers it all. I don't think anyone would know I did it cause it looks stock, I'll try to get a pic tomorrow.

I have discussed this with Bill a couple of times and he said that he dynoed this type of mod several years ago when he was working up the calibrations for the EDGE Evo tunes. I believe he said that he also tried it with the snorkel removed just breathing air from the engine bay and it showed about the same gains. Personally, I like the idea of going back to the fender and taking cooler air from the stock location since cooler air is more dense and makes more power. Also that location is less likely to ingest any water unless you manage to submarine the nose of the truck, in which case the last thing you will be worried about is where your intake air is coming from.
