Anyone put a pulley on a high mileage mini? Bad idea?
I'm getting ready to pick up a cheap R53 mini just for driving back and forth to work. The ones that are in my price range are all around 70-90,000 miles. I would like to get some extra power out of the motor just to make it more fun to drive...so I'll probably put a 17% supercharger pulley on it.
Is that asking for trouble on a higher mileage mini?

It's totally safe. I installed one on a car at 100k and now it has 206k with no ill effect. Same supercharger and still original clutch.

Lots of previous threads on this... Yes, definite improvement in acceleration - best bang for the buck! Under normal driving, should be no adverse effect on mileage. In fact, my average went up about 1-2 mpg's IF I resist the urge to hear that wonderful supercharger whine!

It is like a night and day difference, pulley vs non-pulley.
minis are setup to run pretty rich....addingthe pulley justs adds more air...the computer then adjusts the fuel trims for light accerlaion, but must still use the stored maps for hard acceleration....so very high rpm running (close to red-line) will be leaner than optimum, but generally safe....another side effect, on the mini, the waterpump runs off a pto on the bottom of the SC, so the waterpump is getting run hard...ok again till the redline area...
it is generals agreed that the 17% is great for street/highway driving, with limited redlining, while the 15% is better for an agressivly driven car. Many threads.

This is the type of intake it's got on it....does anyone know what kind it is? I'm assuming that I can just wash it and re oil it like a standard foam filter?
Thanks!
