do you think if I fill my tank with pure octane booster I can get it in the low 9's? that is if I retarted my engine. what about going alcohol injection. what brand is better for HP? Bacardi? and was wondering if anyone ever tried everclear? 1 last question...I didn't have any gear oil so I filled my differential up with vegetable oil instead....is this safe? I also didn't have a gasket for it so I used elmers glue to seal it....its still drying.
