My mini has got faster ! When I originally bought her she would max out at 78 - 79 mph fitted with an RC40 and std air box/filter.
I have changed the exhaust to a twin exit job and put a K&N cone filter and stub stack on and I got her up to 85mph this morning on the M3 and I reckon she would hit 90 if I had had a bit more room as the tacho was only up to 4000rpm

How exciting ! lol
