98 RON Fuel + Water Injection/Methanol = RON ?
Hi,
Just wondering if there is any specific calculators or general rule of thumb of how HIGH can I increase the octane rating with water/methanol injection from 98 RON unleaded fuel ? Doesn't have to include methanol, but what & how much do I have to use to achieve the following octane levels a) 105 b) 107 c) 110 Thanks |
No there aren't any calculators or rules of thumb. Also water injection won't necessarily increase the octane as it is measured, but it can be octane equivalent. What I mean is you can tune it in a way that is very similar to an octane grade tune - but it won't be exactly the same.
At 12% to 17% water injected to fuel injected ratios, I have seen many tunes that were very similar to a 110 octane tune in terms of fueling, timing and performance. |
