Cooper s upgrades

[tonka007]

Hi all, just wondering if I could get some advice on upgrading a few things on my R53 cooper s? I'm thinking of fitting a supercharger reduction kit and getting the car remapped or chipped. I was told I would get about 15% improvement on performance but also improved mpg. Is this true? I always thought the faster you make it go the worse the mpg! Also looking at induction kit if anyone can recommend a good one.
Cheers

1320 mini just extra coopered me

Just recently been sorted out by the guys at 1320! pulley pack 2, Had a 15% pulley, belt, plugs and dyno tested before and then after. The first dyno was poor 142bhp/125bhp? on the original set up and located to a worn out and non functional bypass valve and against a new bypass valve was fitted and shown what and why the valve had ceased....brill service through out and shown what was wrong and then after all parts fitted the transformation was outta of this world.

The car is now what it should have been like, but me knowing no better thought this was how it should be, how wrong I was.....after driving up was a slog, but the drive back was fast and took the longer route home...biggest grin factor yet

Thanks to the guys at 1320, Tom, Scott and Jack who fitted the parts, dynode the car, now reaches 174bhp. If any thing get the bypass valve checked if it lacks power, the lever of the old valve pushed into the diaphragm stuck not fully closing loosing power...against the new valve with the flap fully closed. I could see and feel the immediate difference and experience the speed. Saving up for the next mods…..
