Trail and error (s) Still had fun at LVD
Why are you running mixed fuels? Refresh me on the build if you dont mind. You are a little off on the gearing change. It does mutiply the torque to the tires, but more importantly it lets the vehicle catch up to the spinning tires faster... So over all, you will be quicker. Generally 1 tenth on the 60 equals 3/10s at the finish. So if you can go a 1.90 60' you should be quicker than 13.50. More important is the mph. 106 is no slouch. It's got 12s in it if you get it all working perfectly.
