I wouldn't trade the low-end torque that I get with the roots-type supercharger for anything. Even going up HUGE hills, as long as my RPMs were above 2000, I could maintain speed, it took very little pressure on the accelerator to go FASTER. On level ground, ANY pressure on the gas pedal adds speed, it's GREAT! It's also a ticket waiting to happen though. There were more times than once today where I looked down and I was doing 70-75. I'm sure Turbos and whipple superchargers are great for racing, but you can't beat the roots-type for driveability. I truly LOVE driving the 'trac now.
