hi so I always wondered why not supercharge for low down torque and then somehow at a certain rpm it cuts out and the turbo by then has spooled up. I think nissan made a similar system for the nissan march superturbo MA09ERT but i want to know what controls the engagement of the supercharger is it rpm based through a ecu? or is it psi controlled some how?

would this be easy enough to adapt to an a12? if so what is needed to control these? im guessing you could use either a amr 500 or sc12 supercharger or sc14???


Thanks!
