IMHO after driving Lenny's Trooper two times in the last few weeks, It is about twice as fast in acceleration when compared to a stock Trooper. The power was pretty smooth over the entire RMP range. Not a blast of power and then nothing like nitro and the lag was not quite as bad as a turbo. I will say I am not fond of the whining sound of the supercharger, the only neg that I found.
