You are right Alistair!
That was a mistake on my part - trying to multitask and needing coffee!
In fairness, in spite of the addition of variable valve timing as mentioned above, the actual bhp figures seemed to vary from engine to engine - some of the claimed 286 performing better than the claimed 330.
That is interesting Simon, how much variance was there with the 286bhp engined S1's? I always thought being BMW engines the tolerances would be quite tight.
With regards to the S2 engines having 44bhp more from the VVT, could this not just be retrofitted? A lot of power there..
