all right, im going to work out what im trying to say while saying it, so it probably won't make much sense, but:
I have always known that higher octane is just to help against a case of the knocks in high comppression applications, right? Well, what about forced induction? Is a higher octane needed then? I mean, I know there's a difference between say a turbo probe and an STI, but would the probe require high octane?
And what about bikes? My friend has a Ducati 750 super sport and a triumph TT6, the triumphs compression is 14:1 and he normally runs 93 octane, but he says he has put 87 in it before and it ran fine.
And the last question I have is this; if a car is made to run premium only, like say a third gen rx-7, and you always put premium in it, will you get any performance gains off racing fuel, lke 101 octane?
