I dynoed my 2011 S1 (13K miles) in pure stock form except for cooling radiator added in rear, underneath the engine) on a Hunter dyno yesterday with temps in the 40s. The best of 3 runs was 294.58 hp. Is this pretty much in line with other dynoes of S1s? I plan to add headers, CAI and tune. Not sure about a larger crank pulley, but I don't believe I will install a smaller s/c pulley. What do you suggest?
