    With the big difference between 98ron and E10 prices, I'm thinking off running E10.
    Anyone know if it will effect the original fuel pump and main fuel line?
    Not worried about after the filter as that has all been replaced with new parts.
    I'm running water/meth/nitro injection so I don't really need the 98ron.

    Well, I guess I'll answer my own question.
    Filled up with E10 today. Motor responded well, but I'm sure that's due to having hydrogen feed into the intake system. Hydrogen flame front is very fast, so less timing is needed.
    This was the other reason I wanted to try E10. The slow flame front of 98ron wasn't helping when running hydrogen.

    My only query would be concerning mid range ..... I'm assuming your cocktail injection only comes in @ X boost, so how crucial is the need for 98 between zero & X boost ?

    Straight water is injected from 0psi boost to 10psi boost. After that the front tank is turned on also, for a 75% water and 25% meth with half the nitro mix.
    After 15psi the straight water tank in the back is turned off, so the mix is then 50% meth, 50% water and the full dose of nitro in the front tank.
    I did have to retard the timing for the off boost driving, but I have hydrogen fed into the intake system all the time which has a very fast flame front and also boosts the octane levels.
    Over all, I'd say it's better with more low down torque.

    Sounds like a complicated system, what is the brain controlling it? More details on the setup?

    Just 2 boost sensors and 2 water injection solenoids to open/close 6 mm hose. Also a 10 litre tank in the back and 3.78 litre tank up front for the witches brew.
    Originally it was a snows performance kit, but just days after the 1 year warranty, the controller died and I bought another new one for $500. That's just for the 2" gauge, the controller is contained within. Replacing the big black box from just 1 year ago!
    I have the AEM failsafe gauge/controller also, and I have that setup to just reduce boost to wastegate pressure.
    The main snows controller just allows you to set when you want the spraying to start, and what pressure you want it at 100% duty cycle. It also allows you to trigger another solenoid at a pressure above the max duty cycle pressure.
    I have that set to spray water pre-turbo at 18 psi.
    Regards the hydrogen, that is controlled manually via a 30 amp PWM mounted in the center console. I just dial it to 10 amps around town, and 15-30 amps on the open road.
    My mileage has dropped to 7.5 Litres/100 km's @ 119 km's speed.
    It also greatly helps cover the extra fuel needed if a strong dose of nitro is used in the witches brew.
