IMHO crappy bolt on turbo or supercharger kits cant and dont give a true representation of what they are like, makes superchargers seem nowt special, and makes turbos seem lag free lovlies.

This might be the case on low boost/power setups, but not in general.

And no matter how responsive and small a turbo is, it never gives the same feeling, theres always "lag", without ALS throttle position and acceleration is never directly proportional.

Saying all that though, id go turbo 99% of times as its much easier and more adaptable when you want to change stuff.
