Guibos for V8 torque?, like the 917s Options

[DougC]

Hey guy I have an idea to handle torque to the 901s from a V8. It involves a rubber guibo or flex disc. My E30 M3 has one that fits between the drive shaft and transmission flange. Now, I was looking through a book I recently bought entitled "917 the winning formula" all about the great Porsche race car and others like the 907, etc. A great book with lots of pictures and the inside scoop on the early racing successes - I highly recommend. In one of the shots you can see very distinctly 2 rubber flex discs (guibos)between the half shafts and tranny on the 917. I swear from the picture they looked just like the one on my M3. Of course major mods to the shafts and tranny flanges would have to be developed for our application but do ya'll think this would help torque issues. Maybe the BMW parts could be incorporated with larger CV joints? What would be some of the most obvious hurdles? TIA.

There are bigger, beafier flex discs than the one used on my 4cyl M3, actually we replace them with one from an E34 M5 (IIRC). You wouldn't be shreading two of those quickly I don't think. I replaced my original one after like 120K+ miles on the car and it wasn't shreaded yet but of course we're not talking much torque at all with the E30 M3. I think if you let it get to a point of shreaded and doing damage to the car then you're probably not paying much attention - but I guess it has happened. I see the point though of angles of operation and like someone mentiond, there's more a problem with tranny internals and it would add unsprung weight I guess. Just an idea after seeing those 917s which would run 24hs sometimes. BTW, they are a pain to change on the BMW..
