Can you share those *kof* 100% performance increase figures perhaps? That 3/10ths of a second quicker to the next set of lights time?warmasice wrote: ↑Fri Nov 13, 2020 1:18 am
I don’t get it tbh, not just you but everyone who claims their car goes faster on super/98RON. It must be such a marginal gain for owners willing to spend the extra on premium fuel, what with all the speed cameras on UK roads preventing owners from exploiting all that ‘extra’ performance and most owners not racing or tracking to be tricked by the brand marketeers into a real placebo.
No offence, I’m all for and believe in the power of placebo speaking from first-hand experience, it works! But that’s the single biggest factor that the brands utilise and would have you fall prey to. Unless you’re running an engine specifically designed to run on higher octane fuel, with the appropriate cmpression there’s really no point otherwise.
I cite in other threads like these the case of our mechanic Dave tuning our Atom for 100RON racing fuel usually Sunoco FR as I recall,l and it making not a blind bit of difference to our ‘ring laptimes, apart from our thinning wallets that is.
Yes we may have been faster in some places, in certain gears at certain parts of the rev range but overall, no real or significant increase in performance due to downforce and gear ratios on the straights and that’s from driving a car at 10/10ths.....all the time!
Carry on spending on super though, if it makes you feel the car has more zing, why not?
