pressurized nitrous bottle
just wondering what ever happened to the practice of running a second bottle of pressurized gas(don't remember what kind) that the pro mod guys were using in the mid '90's. remember seeing them when i went to scribner,ne when it was an ihra track. didn't really know what they were for sure untill brett kepner said what it was when i watched the same race on tv later. have the tape still yet somewhere.
