BP 102 and Porsche 930
Discussion
As a one-off treat to myself (and my car more importantly), I was thinking of filling up my Porsche 930 Turbo (3.3) with BP 102.
However, as the car is in a completely standard state of tune (i.e. in terms of ignition timing and air/fuel ratio) and runs happily on 95 octane fuel without any pinking problems, I'm not sure how using a higher-octane fuel would improve performance if I left the state of tune unaltered.
A car of the vintage of the 930 doesn't have a self-adjusting engine management system so unless I advance the timing I can't see how I'll get more power or torque from the higher octane fuel.
Is this right, or am I missing something???
