    ^ yeah, 20 years ago I’d simply drive to the local airfield and fill up.

    Now the airfield won’t sell it to you. This is a good think as 100/130 avgas contains much more TEL than leaded petrol we had for the road.

    It was a good thing the county got rid of TEL as the last thing we need is a dumber population o_O

    Yet it appears to be occurring on a daily basis.

    Av gas wasn't all it was cracked up to be. The blokes running it didn't seem to have any more power than i had. At least seldom few of the really good racers used it, because it was more wank than anything. Before super was discontinued i used to use half super and half 98, leave it for two days and a chemical reaction would occur. This increased octane to about 102, which was as good or better as the avgas they sold at Malalla. Now if you wanted fuel to increase power and you were allowed, you would run straight alcohol. That gear makes a huge difference while also keeping engine temps down, thus more power again.

    When was this, and in what cars?
    It'd surely have to be able to make more difference these days than it would have Back Then; given there's a lot more instant adjustability in stuff like cam timing & duration, ignition timing, injector timing as well as duration etc. Back Then it would've been either non-adjustable from the ECU or you'd have to manually mess with ignition & fuelling and effectively "hope for the best".

    When it was, was 25 years ago,as i mentioned above in an earlier post. I am talking bikes, but at the dual meets the cam drivers were racing mustangs, minis, EHs. I have NFI how it would work on a modern vehicle but at the same time never made any reference to modern vehicles. I thought the latest discussion was about historics? When I was racing moderns were for the blokes with massive sponsorships. Historics is where the average bloke could afford to race.

    I'd love to know how say a modern LS would go on straight alcohol. Not even sure if it could be done, given the amount of fuel required to stop it from leaning out compared to 98. Would be interesting to know what needs to be done to a modern vehicle to make it work.

    Other thing I would like to try is octane boost to see if there is any noticeable gains from dropping a bottle into say 20L of 98.

    ^^ the previous v8's were E85 certified so not sure if they could take straight up ethyl alcohol without issue.

    Our LS3's are not even certified for anything more than E10. so i'd think if they didn't have the alcohol safe fuel plumbing and seals as well as internal engine bits (don't they need specific rings and/or pistons?) then they'd have a reduced life on booze.

    Not having enough knowledge about cars, just bikes. But on the old bikes blokes running straight methanol just used regular internals. The main issues you have is melting anything plastic in the fuel system. As for life alcohol burners had a longer life as the internal engine temps are lower, which helps in that tolerances can be a tad closer.

    Advantage i see is that you dump in over twice as much fuel, more fuel more power

    I'd reckon they would go pretty well!
    Bigger fuel system.
    Bigger methanol injectors.
    Larger diameter fuel lines.
    Higher static compression.
    Colder plugs.
    Should be a real weapon.

    ^ Yeah, pity pirate/monstar is no longer active on this forum... he would have set us straight on build issues and the virtues of alcohol fueled v8s.

    i have 400L of 100% ethanol ill be using in my new build, stoich is 9:1 so still reasonable should make some safe power with some boost and rpm, going bigger injectors and already have twin pump setup might be around its flow rate so may have to update the pumps

    Yeah Caltex eFlex is around $1/l again, whilst ‘United bunch o’cunce’ still gouging 50¢ a litre more.
    Worse still, because you rarely need e85 117 octane and petrol is now so cheap, bunch o’cunce have move 98 petrol away from the e85. That’s to stop ethanol customers half or part filling with petrol or vice versa.
    It’s Darwinian - no toilets, one (illegal) underpaid staff, blatant price rigging, and general rip-offs versus typical Star Mart culture.
