100 octane race gas!
Was driving to shell to fill up with my usual vpower 98 and drove past a united petrol station which had premium 100 octane gas (called race gas in socal I think)! Looked it up and there's 10% ethanol added to Ron 98.
My tank was almost empty so I tried 10L and gave it a bang. Impressive to punch the pedal but maybe I was just excited and imagined a touch more power. Anyone else tried it? What did you think? Ps Shane it's the Merewether united servo close to bar beach.

As far as 100 octane would go, it would just add a little extra knock protection but no performance. You would need to adjust timing and a little extra boost for it to add anything. Race fuel like MS109 is also oxygenated so would also add a little power without tuning but you would need to run a race gas map on your piggyback or cobb flash to utilize it. |

How much is it dude in comparison to 98?
I may be old fashioned but IMO for such a small gain, I would just stick to what I know with the 98 I know the jdm boys in their rexlancerlines are getting huge power on E85.... |

All the ethanol will allow you to do is to run more boost and timing with it being too unsafe. Of course this requires a tune to suit. Apart from that you may notice better combustion but won't see the full gain.
