>I just purchased a 2007 JCW fully-loaded with JCW suspension and trying to figure out how to get the most out of it in a straight line. I previously owned a 2004 JCW with CAI, 2% crank pulley and HSport suspension with
comp. rear sway bar. It handled rough but strong and power was in abundance. You know. With the 2007 being a turbo, and a power band from about 2000 to 5000 I am having a hard time figuring out how to get the most power out of it all the time so I constantly feel the pull on a straight line acceleration. Any tips?

>What I’ve learned so far is that I get more pull out of partial acceleration than peddle to the medal. Did you experience this as well? I’ve driven the factory JCW and it felt more like my 2004. I’m thinking if the power
band continued further it might feel better. I’ve seen that some cold air intakes are supposed to do this. Again any help would be much appreciated.

Honestly I never had any issues with finding power on my R56 with the JCW engine kit. With all the torque down low, it was easily the fastest MINI at the track I had ever experienced at the time (including the GP. However the power characteristics are indeed different from the R53 JCW and the factory R56 JCW. So we’re going to turn to the MF readers for this. What have you found to be the most effective at increase power in an R56 (or R55) in the mid and upper ranges of the RPMs?
