Tuned exhaust for the Lycoming 0320
I'm just having more fun than should be legal and it probably isn't if I
look far enough into the County, State and Federal statues, but I am never-the-less. I have pretty much followed the Cafe numbers for header length and the 4-into-one collector. Keeping in mind friendship to my neighbors, I also included a muffler. I purchased the collector and muffler from Barnes Stainless and will be purchasing the header tubing, 321SS from the same source in all likelyhood. A/C Spruce has the tubing listed at $8.75/ft. I've made up some PVC headers complete with flanges glued on and am heating the PVC with a heat gun and bending them until I get the pipes where I want them. The plan then is to take the bent up PVC to a muffler shop that has a mandrel tube bender and have them bend up the expensive 321 SS tubing. I plan on welding in some of the 3-bolt ball fittings to both ease the stresses and make installation and removal easier. My plan is to install the stock exhaust, do a hover and check the MP and then quickly change exhaust systems and repeat. I'm hoping to see a MP improvement. I've had this plan in my "Round Toit" list every since I read the Cafe study. Dang I sure do like the experimental category. No bureacrats in the way. Stu |

Stu Well the heating of the PVC wasn't working as well as I hoped so I changed to using PVC elbows. I modified some 45° elbows by cutting out a wedge fron the outside of the elbow and reduced the angle to 30°. I had to drill a couple of holes and use some safety wire to hold the elbow to the 30°. I also turned the PVC pipe ends in the lathe to make them turn a bit easier in the elbows. Needless to say it is a projet in progress. Stu |

I also turned the PVC pipe ends in the lathe to make them turn a bit easier in the elbows. Needless to say it is a projet in progress. Stu Well PVC elbows weren't working to well either. Couldn't get equal length pipes to end up in an equal place. Next tried 3/4" steel flex conduit. OK it proves that you can get 4 equal length pipes to end up at the mouth of the 4-into-1 collector. It does prove that the required bends are not simple. However the steel flex conduit is heavy and tries to sag. Next tried some 1- 1/4 flex aluminum conduit. It isn't heavy but it too sags all over the place. One thought was to get the conduit in place with support and then put a bunch of tack welds to make it solid. Yep the conduit is weldable but it will take welds on both sides to make it rigid. Next trick being tried is using an expoxy to coat and stiffen the flex conduit. Also trying some permanent thread locker and some 5 minute epoxy. Sure would be nice to have some medium that was flexible but kinda stiff that could be treated with some easy to apply medium when the proper angles were achieved to derive a stiff pipe that could be copied in SS. Yes I'm having fun and hopefully learning some things and not just killing time. Also hope I'm not just wasting time posting this on a dead NG? Stu |

Betsy was crying and trying to scream but her mouth was full of cock. The guy ****ing her showed no mercy and ****ed her harder and harder Soon he pulled out and shot his load sex videos all over her. The guy who ****ing her mouth got down and took his turn at ****ing her while another cock filled her mouth. Betsy kept trying to get free but there was to many of them so soon she just laid there crying and praying for this to be over.
