    As i remember form the old popular science /mechanics articals on run your car on alcohol. They said double the jet size. Your engine is a little low on compression ratio for alcohol. The more you add the cooler the burn. It eventually puts fire out. Racers used alky in high compression engines to cool the burn to stop detonation. Was talking to a pig and ford racer and he tried to use av gas in a model t and it almost did not run on it because of the low compression ratio around 4:1 . Good video

      Isn't that 99% Ethanol instead of 99% Isopropyl? E100. In the US we have E85, so people don't drink it.

    Ive always wondered what would happen if you did this. I totally thought it was done for when it started blowing smoke, but it powered through! It was so interesting to see how it lost torque as the alcohol purity was increasing

      I imagine it's near the same as running Ethanol. Different AFR than Benzin/Petrol/Gas.

      @@unigrampa oh nobody it's a little more than that I have literally five lawn mower motor sitting in the back of my house because these "no oil change " mower ALWAYS blow piston rings even when you change the oil. All the carburetors on every single mower is good every single one of them has blown piston rings and one of the mowers was only used twice bought brand new from the store
      They just make motors really shity these days if they put something like this on lawn mowers they would run forever.

    I'm actually surprised it ran on 91% ISO. 9% water is a lot. You should try 99% to see if it's any different

      "Most isopropyl alcohol is only like 30%" You mean 70%, 90-91%, and lab grade 99%?
