I guess this mile stuff is pointed toward myself, one of the few that has the balls to do these events.....
Id not call my car badly setup and it had no pre existing problems i know off, still killed two engines at two events.
Blame could be pointed but when you are running 3 times the power of a stock tt things can break or not go as planned, my last one melted a piston at 191mph (0.71 of a mile) i have never held my foot flat to the floor for so long other than at thunder road, i guess its hard to map a car to take into account of a run that hard, on a dyno its a short blast in one gear, who knows, maybe something else caused the piston to melt.
Either way its a risk i dont mind taking, i learn from these things and come back stronger, its all for the love of Supras and having fun in my car, i have enjoyed every second of it and will continue to push it as hard as i can.
