another mouthpiece thread

i know theres been a ton of talk on here about lb7 mouthpiece conversions at the risk of burning every one out i thought i would tell you guys i finally put mine on. i used a 4 in aircraft vent duct sleeve for the coupler. i also machined a flange from black pvc stock that was bonded to the shortened intake that was the same dimension as the flange on the new mouthpiece. i havent pulled my trailer yet but it seems to run better. i would like to make a cold air inlet, remove the convertor or maybe complete exhaust and send the pcm to killer bee to be reflashed to further improve it

Well hurry up and figure it out. It always leaves everyone in suspence wait but thats what keeps everyone coming back for more. If u have them on your computer u can email them for some help posting them. Photobucket is pretty easy to use.

+1 for pics, I have the same dilema ahead of me; what do about the MP. My buddy has a LBZ mouthpiece he'll give to me but I'm not sure what kind of fabrication is ahead if I take it off his hands. I've just got to take it apart and see for myself this weekend. A little exploratory surgery never hurt any.

I too want to see pics of how you were able to mate the LB7 mp to an LLY's turbo.

Or did you mean the LBZ mp? :tease If you need help gettin' 'em up, just PM me.

im a moron, i meant lbz. the original intake wherecut to mate with the new mouthpiece is smaller in diameter than the new mouthpiece by about 1/4 in. plus its thin and not really meant to be clamped although it will work as referenced from the guys on here who have done it. so i machined a flange thats the same out side diameter as the the flange on the new mouthpiece. the cross section is an l shape that presses inside the tube 1st then goes into a reciever groove. it also has a ferrel machined into the outer edge to prevent the coupling sleeve frome slipping. the inside edge was radiused for airflow. i bonded this to the original tube. its similar to the clamping flange on the original intake

LOL now that makes sense. Common thing for the LLY owners.
