between 8-10,000 in fifth gear. The flashes of light were from the air shifter kill timing set long so it would backfire between shifts. Throws a nice flame doing it that way.
you probably heard my onboard air pump. Tranny was fine. I did find out when we got back home I had broken my rear intake cam (earlier in the week we were down there). The popping and farting is what happens when you set the kill timing too long on your air shifter setup.
Are you using a 555 Industrial timer for your kill or the old dinosaur air kill with measuring the air line to control the kill by MRE? Those things suck and they will eventually cause you to bend a shift fork when it fails. Spend the the 100.00 and use an electronic to kill the ignition they are fail proof and you can dial them em better and more precise.
