I have changed up from a R53 JCW to an R56S, and even though my Supercharged version was quick, the Turbo'd version seems to be a bit quicker. Superchargers will allways have an advantage on acceleration because they are instant power due to being mechanically driven. Turbo's, for the best part have lag, my old Scooby had so much lag when the Turbo came in the back end would step out, BUT, on the R56S, it is such a tiny amount that it is not even noticable. I myself have allready agreed with my BMW garage to upgrade to the full JCW model when it hits the dealers, so i will look forward to seeing the difference between all 3 cars, the only one i am missing is the GP then
