[QUOTE="westgl, post: 97226, member: 2025"] OK guys I have been reluctant to bring this one up. But it should be discussed. You could use what you already have, instead buy the VW manifold. Put at least some of the Cod Catcher to use. Use the OEM GL1100 Plenum only. The GL1100 plenum, is still fairly small, already has the Runner offset done, just a matter of connecting some straight runners to it. Some 1/4" alum. plate across the left side cyl. bank covering the runners, holes cut toward the lower part of the runner exit, Any size you want, as long as it is 1-3/8"id. coming out of the plenum, then another plate, mounted to the Right bank, doing the same. Hole saw to open plenum runners in new plate. I may build this too, as i could do this fairly quickly, It would be very easy, and straight runners, No bends, could be alum. or steel, alum. can be [u]High Temp silver soldered with a propane torch[/u]. easier & cheaper than welding Alum. plate mounted to the top, w/ bolts (bolt heads chopped off, or all thread, I like grade 8 bolts) threaded into plate carb placement.
