Neil,
The engine is still in pieces and the exhaust is not decided............I may turbo-normalize
which may do away with the need for a muffled exhaust system.......The alum center and
rear housings are an expensive 29 lb weight reduction (prop end of the engine)..........<:)
Had I used the alum front side hsg another 10.5 lbs would be lost.........Attached is link
to "Racing Beat"............
