one more thing... our cars need MORE low end torque. everyone is so worried about peak numbers and how much hp they make a 7500rpm. who cares. you aren't going to break into the 13s with high peak numbers. you need more at the bottom end, twin turbo setup offers more torque at a lower rpm, which is what this car needs. yeah a single turbo might get you the big numbers, and might do it more efficiently, but a nice sized twin turbo setup will get you the wins, torque rules, and we have very little of it.
