I just had a call with a nearby S&S spacialist in Germany (20 Km from my home). He told me that there is a rev limiter for the first 20 hours installed in the engine`s mapping for running in. During my test drive there was a cut at 4.800 U/min. and that is why it felt not very strong. He told me the bore/stroke ratio is square, so revs around 6.000 U/min won`t be a problem. Tuning won`t be a problem as well. At first it would be usefull to have a look at the intake and exhaust system, if the engine can breath freely. Remapping can be done easily. But also mechanical changes are possible. So 120 or even 145 bhp won`t be a problem.
