  • 1 gallon VP M-5 racing fuel + 4 gallons pump gas = OMFG!!!

    So Ryan got a 5 gallon drum of VP M-5 racing fuel which he was planning on adding it to his water/meth injection to see what it would do. I came over to grab a gallon to try it myself. Problem is, despite the fact that it's 99% methanol, we found out it would not mix with water.

    Faced with this conundrum, we thought "hmm what could we do with this stuff?" . My answer was "hell I've got a 1/3 of a tank left, let's add a gallon of M-5 and see what happens. The answer was "holy fuc*ing sh*t was my car faster". Yes, Black Betty has a new Meth habit.

    Between the water/meth and the M-5 I could not get my car to pull any timing no matter how hard I tried. I have a vid of a 3rd gear pull from 3000 to redline at 21 PSI (I'll try and get it posted tomorrow) and I couldn't pull so much as one degree of timing from all four cylinders.

    This stuff is weird though, unlike Methanol it won't flash when applied to a surface. It also smells sweet. Not quite like race gas, but similar. It must also be heavily oxygenated because my ECU added 7% to my fuel trims and my wideband read about 0.5 higher.

    The only downside is that a) it's probably not to kind to your fuel system and b) you have to run your tank to fumes and then fill it full to flush the M-5 out. Other than that though, it may as well have been race gas. Only this stuff only cost me $20 for 1/3 of a tank worth.

    Who measures in gallons?

      ^^^ We still trade 85% of everything with the US. So we're effectively a two-system country. Pal.

      I know because plenty of industry still builds new or retrofits using imperial measurements.





      This would be hella fun though...

        Its also easier to say 5 gallon as opposed to 18.927 Litres..
        Not to mention with VP Racing Fuel being a US company.. they use what they want

          Would be sweet to test out that fuel $20 is not a bad deal.

            Regardless, Metric wins. :P

            More on point, what's the negative effect of having a tiny bit of the fuel left over in the tank before a refill? Mess with the tune?

              No, I recommend draining the tank because Methanol is corrosive. Now, whether or not this stuff is with it having nitroparaffins added to it I don't know. When I get a chance I want to put some Aluminium in a container with it and see what happens.

              Also, I don't know what some of the hydrocarbon additives will do to the seals in the fuel system either if left to sit there. I just figure it's safest to try and purge as much of the M5 as I can before letting the fuel sit for any amount of time.
