I saw the new upgrade for the cooper s and thought it was interseting. But what they dont mention is how or where you could route your intercooler and next to that what do youdo with the supercharger already on there? Any comment would be good to know.

 

Judging by what I've seen the Alta kit is a twin-charger set up. So the S/C stays and works in conjunction with the turbo. It also appears that it uses the stock intercooler, although an upgraded one would be a better idea......as a precaution.

Rock's all over it, supercharger and turbo!.. Although if you want to make BIG power, ditch the supercharger and run turbo only.
