  • Compressed air supercharging

    Have any of you guys been reading up on this or see anybody at the track using this? I think Hot Rod magazine did a story on it a few months back:
    '70 Mach 1 - '72 Sprint - '94 F-150 XL -'97 E-150 - '18 Edge SEL AWD

    I remember reading about it a while back. Cool idea but seems like a big PITA compared to other power adder options.

      Interesting. Looks like it would be a PITA to fill the cylinders. I wonder how many 1/8 mile runs two bottles would make? If they can get the fill stations in and it's cheaper than nitrous, it might catch on.

        3400 PSIG is ALOT!
        I'd be VERY concerned with damaging a cylinder or severing pressurized line upstream from the pressure regulator!
        It makes N2O cylinder pressures look like a pop can pressure.

          Interesting side note: I believe the Germans played with compressed air in thier fighter aircraft during WWII, which led them to using Nitrous Oxide instead due to the cooling effect. History repeats itself maybe. Will read article.

            All old things are new again...

            This picture was taken at Brent Hajek's museum in OK. He said the story behind it is someone (don't remember who it was, but it was a familiar name) was looking at trying to get compressed air used in Top Fuel. They had been making really good power with it and had invited Wally Parks to come see it on the dyno. When Wally showed up they ran it and blew things up in quite dramatic fashion. Unsurprisingly, he didn't approve it. This was one of the "other" engines they had ready to go. I'm not 100% on the story, so if someone else has heard or remembers the details of the story better, feel free to correct or add.
