Well when he launches i'm sure he's going to be launching in his powerband, not 4000rpms below it and when the car shifts, the car will stay in the powerband so he will have full boost 99% of the time.
well, im sure he will launch in his powerband....im not argueing, but , i couldnt see twin t-66c spooling anytime before 5500rpms. twin HKS GT3240's on a supra , which is about the same size motor starts its powerband at 5700rpms . i think its more of a show car than race. i'd imagine it would work ok with a little NOS.
