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. The car http://www.turbominis.co.uk/uploads/i/wh960-oe1/sprocket-2942.jpg The Engine A BMW K1100 16v Twin cam cylinder head engineered to fit a Rover A+ Series engine and transmission with a SAAB 93/95 Mitsubishi TD04HL-15T turbocharger. Engine is 1293cc and compression 8.5:1, I could have gone much higher but the combination of parts gave me this without going positive deck with the pistons. That said, I know I can throw 30psi at this and it'll still work. The same combination already dyno'd at 268hp on 20Psi boost, so lots of fun to be had!!!
