Thanks for the info HIND. This was partly why I asked if anyone had any dyno figures for their M3W on a dyno other than the Krazy Horse one, particularly as S&S said themselves that 135hp should be easily obtainable. Chris99 mentions, Krazy Horse's own Stage 3 car "only" made 125hp on their dyno......although it sounds like a bit of a beast to drive. I remember seeing it at Shelsey Walsh hill climb and it was a handful.
My car, also Stage 2 with roller rockers, was recently set up on a dyno in the Midlands and (to my surprise) recorded figures closer to HIND's car than the "normal" range of Krazy Horse. The dyno operator said that it had been recently calibrated and should be accurate. All academic as I am fairly sure that they all run within a narrow band for the same tune.
