Summary of change:
All older information previously on this page can be found here MembersPage/Sprocket/OldorObsoliteInformation All latest information shall follow, since this is the same project, just the latest progression. ---- The good old Austin Rover Mini with its antiquated A Series engine which has its roots back in the 1950's where long stroke engines were favoured as a result of taxes imposed on cylinder size. Would anyone believe the A series engine would be so durable and yeild such power figures as they do these days? Well, here's how it's done, or, here's how I have done it at least, and note, this is a conservative build, there is room for improvement.
