LLY mouth piece????

[Big Smith]

I've seen the threads for the new retro fit but, my qustion is: Will it work with an aftermarket air filter kit ( I have the K&N) and where do I get the new mouth piece?:

This is what I have done...............

Fill out your sig line with truck info. Drop Killerbee a PM with info and questions. He wil send an invoice to your email addr(which he needs). Pay for it and he will get shipped.

I have a AFE Stage 2 intake on my truck. I pulled the Mouth Peace off of my truck and ported it myself. It is very easy. Just remove it and port it. It took me about 30 min to remove port and reinstall.

It takes me longer, with 4 different 20,000 rpm long reach tooling bits. About $500 worth of tools without the compressor, though it can be done cheaper. There is a lot more that can be done to it. For example, round the internal junctions where the PCV and resonator join up. Very hard to get to, these are areas with boundary induced turbulence that help reduce that pressure drop.

When it is done, the entire internal has been machined. The inlet area can be machined a lot, especially on the bottom. You can get another 1/8", and reduce the rate of taper.

I finally completed the milling procedure on the stock LLY mouthpiece yesterday. What a PAIN in the Ar$e, 3+ hours but, It looks great with nice tapered smooth flowing curves. I've worked with steel pieces that were softer than this stuff, amazing.

I was only running 16k rpms but the rotary tool I used was very short, which enabled access from many different ports and angles. I was able to remove a considerable amount of material and found several other areas that needed the ‘Porting’ done also.

After:

I have already noticed a considerable change in throttle response this morning, but only a light load of 9.5k lbs total hooked on. My larger load scheduled to test today has been delayed, waiting for money drafts on the other end.

Tomorrow, I’ll discover the true improvements while hauling heavy.

Had to share an after-Mod incident...pulled up beside a Charger R/T Hemi being test drove this morning from the used car lot I had just passed a ways back. Green light and he punches it as I just keep up without pouring it on...I know the light cycles and the next one will change, so I back off.

Leaving the next light, he punches it and I keep my bumper 5 feet ahead of his, he sees I'm inching ahead so he dumps it WOT, grabbing a lower gear as I notice the up/down motion of his front bumper.

Too late of course, for now the Allison’s caught 3rd and the turbo is fully cranked, on into 4th and this 4-ton truck is just running away from it, slingshots into 5th and seals his fate by over 5 car lengths. This turbo and fuel flow action is now very different from before.

I’m still giggling…wondering if he made the 'Hemi' Sale!

That's a great story. I don't run mine often but the other day a new mustant gt got on my butt. The next light I made to where he and I would be there togther. To my suprise it was a fat ass redneck with his wife and a salesman. So I jump a little on the red light and get his attention. He looks up and just laughs. So needless to say when the light went to green all he saw was the ass end of my Dmax leaving him aways back. Laugh at me will ya,... who's laughing now..bitch.

Where is this piece on the motor? Can somebody like me tackle this little under taking. I did install my egt probe myself that was easy. I would like to do this mode to help with the temps under the hood. Does anyone have pics of the part on the motor so I know what I am looking for. I think I see the right part but it looks like it is a pain to get off. Any tips... Thanks in advance, this site is great!!!

The only pain is breaking loose the PCV inlet hose while holding the hose clamp loose, I used a pry bar. Other than that, easy stuff.

Hard to see, using a 5/16” socket, loosen the hose clamp at the Air box, and loosen the hose clamp at the other end of the intake tube, and then remove from the Mouthpiece.

Remove the turbo resonator (black plastic displaying 6.6) from the Mouthpiece using a T-30 torx and loosening one more hose clamp.

Remove the PCV inlet line (see picture with resonator plug installed in mouthpiece inlet),


and finally, loosen the last large hose clamp at the turbo to remove the mouthpiece, seen just below the G A R of Garret in the pic.

When replacing the mouthpiece, it helps to have another set of hands to help position the mouthpiece and hose clamp while tightening. Go ahead and move it from the 12 o'clock position over to 9 o'clock to make it easier. Also, reposition the spring clamp for the PCV 180 degrees (facing forward) to make it easier.

I put the ported mouthpiece to the test yesterday.

Total GCW was 33.83k lbs,
distance one-way was 215 miles,
ran at the hottest part of the day,
2-6pm at 100+ degrees over moderately hilly terrain at 68-72 mph.

The Engine temperature stayed at one mark below 210, and never varied. The Allison stayed one mark above 200, constant.

While there was significant fan activity, gauges showed moderate action the whole way and the D-Max never lost any power, as it could have run faster…kept it down though, worrying about overheated tires possibly blowing. Proven, this mod definitely works.
