Tim was correct, The throttles were made from pieces starting with a set of TWM 46mm bodies and intake. The flange was cut off the intake runners and then the runners were seperated and machined at 20 degrees to improve the entry of the runner into the head as well as increase the distance from the header to the bottom of the bodies (less heat). I made the flanges to be 4 bolt instead of 6 bolt for the purpose of adding a second set of injectors in the flanges pointing right at the back of the valves. The parts were all welded up and then smoother out to look like cast again. I added a bunch of material to the inside radius of the runners to smooth them out as well as giving more material to straighten out the inside of the runner. The path is much straighter than it looks from the outside. The flange mounted injector bosses are not welded in yet, they will be smoother in as well. Here are some pics of the process. Sorry if there are too many pictures. Jeff

Yes Wiggins clamps. You will never see hump hoses used on the upper echelon of motorsports. (Not that my car is that, I just want to pretend) The Wiggins clamps offer 3 degrees of float per end and the bore inside remains smooth and free of any turbulence causing "humps" in the plumbing. They also are 1 hand quick release, no tools needed. They are so good, except the color purple, but it is a Mil Spec specification for this type of fitting, just like the red and blue on AN fittings. Tony, FWIW I fully appreciate your insight and ability to apply your real world experiences to so many different areas. Really nothing much from an engineering standpoint is new anymore, much of it is simply reapplying ideas and techniques from one industry to another. This can be as obvious such as military to automotive, but it takes a real creative person to see the brilliance in the simplest most unappreciated things we take for granted. Jeff

Hi Guys, Thanks again for the input. I can see your point that is probably such a small difference it probably won’t make a difference. The truth is, I am just a freak about this sort of stuff. I am really trying to look at every part of the system, and push it for a "textbook" approach. Bottom line is I like the challenge of figuring it all out. Here are some pics of my build. You can see how I am looking at everything from headers being equal length, to minimizing bends in the plumbing to simply how the air flows in and out of the intercooler. The horn in the question above will be built into a carbon plenum for my ITB set up. Sounds like I will stay with the round inlets.
