im pretty new to the mini cooper scene but ive been building mitsubishis and hondas for over ten years so im pretty handy under the hood and with aftermarket performance. my question is i cant seem to find a supercharger upgrade like a bigger supercharger. ive scene many pully upgrades and turbo upgrades. i want to keep the car supercharged and make around 280-300 hp on a supercharger and it seems like the stock supercharger would run past its maxefficency with such power numbers. so has any1 found or know of an aftermarket superchargers for the mini cooper s? any feedback is greatly apriciated.

 

Twincharger time is you want that big of numbers ...

 

Eaton M45 is the SC that's in the Mini's. They make several types, give them a call (800) 386-1911. I haven't seen or heard of a Mini pushing 300 HP, unless it was a rag car, withnumerous mods, like NOS, etc. Not that you can't squeeze and additional 100HP out of the Mini. But that puts allot of stress on an already stressed engine. I have my car at 193 Hp, with several mods, intake, SC, intercoolers, exhaust, ignition. And it goes like a bat out of hell, but when you get into the high RPM it loses it breath, because the supercharger loses it efficiency, at such a high rpm, around 13000-14000 rpms, that thing is spinning. But I know that JCW makes a upgraded supercharger for the Mini. Let me know what happens?
