" You have to actually drive your car first to know if it can perform.. With 700whp+ you're going to be dealing with a lot more factors than you think (wheelspin, drivetrain stress,tuning). These E46 guys have been sitting on their builds a lot longer and are use to the power and had time to address tuning. I would put money on a turbo m3 that has had its time to address all its issues and the driver that has had time in his seat. Good luck to you Sticky, I know JRCART still wants a shot at your car. "
