I searched and found nothing.
So our local club NEW Motorsports (N.E WI) is allowing bushed turbos in 2.6. I have a buddy who has an S472 with race cover. He would like to have a removable bushing made for this turbo to get it down to 2.6. We have a friend who is a tool and die maker and will be doing the machining to make the removable bushing, but final ideas were up in the air for how best to make this work. The ideas I seem to have had, to me seem as thought they wont work with the race cover.
My initial idea was to make a a bushing that would match the race profile of the cover and ultimately meet the rules for amount of inducer depth that is at 2.6" and meet the spec for how close to the wheel and bushing need to be to each other. This bushing would then be set screwed to the original cover.
My buddy first invisioned an idea of having just a cylindrical bushing to fit in the inducer bore that would be set scred from the inside of the bore. This would work for his other S400 he has, but not on the race cover, as the non race cover has the stragiht inducer bore.
We then put our 2 ideas together and thought that for the non race cover S400 that you would make a bushing that would have a constant 2.6" inducer bore with an outer edge to match the original cover and set screw it in. (a side priofile would make a Tshape)
We then checked out the S366 I am going to be running for ideas, but we noticed the small amount (thickness) of the inducer bore on the 300. No more ideas were produced.
*So what I am looking for: any pictures of removable bushings that you may be willing to share Or any ideas that you may be able to pass on. I am all eyes and ears on this one.
The attached photos: S472 with race cover; HX30W to represent a cover that may have the combined idea work; S362 to show small amount of material on the face
