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

[txarsoncop]

Ok here's pix of mine, complete with very dirrrrrty engine compartment:



I used a 2" test/knock out cap, 1.5" test/knock out cap and a 1" plug.

Another shot:



The "ring" you can see on the far end of the PVC is about 1" of a 3" coupling. There's no need to use a whole coupling for an application like this. I didn't even glue it. I shaped the 2" of pipe that protrude into the fender and still had to beat the "bit-o-coupling" onto the pipe. Trust me, it ain't moving.

I had cut the coupling to match the Downspout Connector but then decided I didn't want to use the DC. Used the coupling anyway because it looked cleaner than my shaping job and I'm keeping an eye out for a suitable sealing material to go between the "bit-o-coupling" and the fender. Partly for a more factory look, partly for grins and partly out of OCDness...

Sawzall really effed up part of the tubing, the guard scratched it up some... ach well. Maybe some other day I'll work on cleaning that up. Fixing that will mean smoothing the whole thing though.

That's next on my list...taking off those "mufflers". Looks much better...

Glad to see I'm not the only one that hates those baffles!


I had the same problem with scratches from my jig saw when I cut mine. Cutting it from the bottom side would have hidden scratches...oh well, live and learn.

It turned out great, good job!

Eventually, I want to get rid of the caps and smooth the openings with some type of filler...just haven't figured out what to use yet.

I thought the same thing! I could get my hands inside to all three openings and I thought about taping wax paper to the inside and trying to use the epoxy to seal up the holes...

But then I figured I couldn't match the texture of the intake tube and it would probably need some matrix like a fiberglass cloth or redneck it with screen cloth to help support it; at least while it was drying.

So I got lazy, but I think it's the best possible result w/o doing a LOT of work.

Anyone think it's worth it to use an aftermarket drop in filter with this set up?

I entered this post a while back: http://dygytalworld.ehost-services13...12&postcount=2 No one challenged me on it (which doesn't make it true, but it's my feelings on the subject).

I honestly don't see what a "super" filter does for you after 100 miles (except cost more than the OEM brand). Now a cheap knockoff can be a problem - for instance what would happen if the cheap one developed a hole in use?

Again, I'm quite open to having my opinion changed - all I need is a good counter-argument.

Ok, for those of us who gleefully cut off our Helmholtz resonators (learn something new every day)...

What do the more learned among you think about this information?

Helmholtz resonators Caution: MUCH geek-speak here!
Although this dumb firefighter was able to get the gist of it.

• They dampen resonance... Duh.
• They make the intake air act "springy" so it fills the combustion chamber more effectively giving us better combustion.

Hmmm, not so sure whipping out that SawZall was such a great idea after all...

Do we need to try to get someone to flow bench or dyno the with and without resonators versions to see if there's a real difference? Seems to me that would be the only answer. Dyno both versions on the same truck and see what the results are.

If they are so beneficial, why don't aftermarket CAI's have them?
