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

[kd4crs]

These are all good ideas but I think folks are over-engineering, and over-thinking things a bit. To clarify what I mean I will go ahead and post the instructions, materials list, and pictures for the DWV intake. It really is about as simple and as easy as it gets, no grinding, no fitting, no painiting. Once Bill posts the write up I sent him I will edit this to comply with his wishes. See below:


DWV intake mod for the 2004-2008 F150 with 5.4L engine



Materials:

1. 7.5 inch length of 3 inch inside diameter black ABS DWV pipe.

2. One female-to-female 3 inch black ABS coupler.

3. One rubber downspout connector from the plumbing section of Lowes or Home Depot.

4. One 4 inch stainless steel worm clamp.

5. Small container of ABS pipe glue.



Assembly:

1. Cut black ABS pipe to length and remove any burrs from the ends.

2. Apply a light coat of ABS pipe glue to the end of the black ABS DWV pipe in a one inch wide strip. Apply a light coat of ABS glue to the inside of one end of the female coupler and immediately press the coupler into the black ABS DWV pipe with a twisting motion to fully seat the pipe into the coupler. Allow to dry 30 minutes.

3. Attach rubber downspout connector over end of female coupler and seat fully.



Installation:

1. Remove stock intake tube by removing 10mm bolt holding it in place.

2. Using a large flat blade screwdriver, insert it in the joint at the end of the flex section on the bottom where the notch is in order to remove the snorkel. Spraying silicone lubricant or WD-40 in the joint will help it come out easily. Be careful not to damage the flex section or snorkel in case you need to return to stock.

3. Loosen 4 inch stainless steel worm clamp and slip over end of flex section. Tighten the worm clamp enough that it will not fall off.

4. Insert the end of the 3 inch black ABS DWV pipe into the flex section of the intake and slide it into the flex section as far as it will go.

5. Reinstall stock intake tube and replace 10mm bolt.

6. Slide the 3 inch black ABS DWV pipe out of the flex section and seat the downspout adapter in the fender hole while compressing the flex section.

7. While holding the flex section compressed, tighten the stainless steel worm clamp to hold the black ABS DWV pipe in place.

IMPORTANT: If the flex section is not compressed the DWV intake mod may vibrate or rattle.

So, looking back at the pictures you posted, the downspout connector compresses enough to get in, and through both fender holes so it gets the air from the original source? I have to say I never thought of looking for a downspout connector (and I don't know that I've ever noticed something like that here).

Of course, it may not be necessary to get the air from that original source, but, as I said in an earlier post, here in the Arizona summers, I want to avoid as much heat as possible.

Jack,

The smaller end of the downspout connector fits into the fender hole almost perfectly. Compressing the flex section while tightening the worm clamp insures that there is light pressure keeping the downspout connector fully seated in the fender hole. This also prevents it from making noise or vibrating. The PVC downspout connector helps prevent transmitting noise or vibration into the fender structure, similar to the rubber doughnut gasket on the stock snorkel tip.

Thank you sir! Nice post!

Now I have to visit Lowes and Home Depot and see if I can find one of these downspout thingys.

Jack,

I checked the web sites for both stores and Lowe's has them on the web site but Home Depot does not. Home Depot may carry them but I can't be certain since they are not on their web site. You may also be able to find a similar item at a local plumbing supply house. Anyway, here is the Lowe's link:

I tried to adhere to the KISS principle during the whole development process for this mod.

Thank you David.

The link clarifies things nicely and now I know what I'm looking for. I like the KISS principle too, when I can see how to make it work.

Jack and David,
Got so gunho on this decided to make pit stop on the way home and basically came back with what I saw on David's pictures. I do not think it was over engineering more like pooling ideas but speaking different languages.

Great job once again

Please don't take my comment the wrong way, I just meant that there is no need to go out and buy a dozen different things and try to cobble them together to accomplish what we are trying to do. I like to keep the KISS principle in mind when doing little projects like the DWV intake mod. I am in no way criticizing anyone's efforts to mod their vehicle. Sometimes the simplest solution is often the best.

Do not worry, not stepping on my toes. KISS is a good policy. Thanks for posting pictures.
