JCW GarageInterested in John Cooper Works (JCW) parts for your 2nd Generation MINI? This is where JCW upgrades and accessories for the MINI Clubman (R55), Cooper and Cooper S (R56), and Cabrio (R57) MINIs are discussed.
Wow man that ^^^looks so close to what to my JCW stock box looks like! Just saw your dyno test sheet, was that comparing it to a JCW intake box or a regular mini cooper?
We slapped on the JCW Tuning kit intake and we did not save the dyno numbers but I was there in the dyno booth and we saw a little gain in TQ's with the JCW intake but no real big HP gain. This was on the Cooper S and a factory JCW that was tested. Ours were stock pretty much. The JCW engine with tuning kit was better but not near out ECS intake when measured.
