The E86 doesn't get much love here. I'm planning on some big mods to the little-beast and this was my first step to determine if more could be done.
I spent the day with the guys at Kelleners-Sport today. I was the first Z4 M that they have had the chance to mess with and in a matter of five hours, I am certainly pleased with the results. This trip was to determine if they could read the DME and if so, what could be done.
Well, attached are the dyno numbers and graphs. Doing the conversion from kW to HP, I baselined at 328.937 HP with a stock car other than the removal of the single charcoal filter. A post ECU tune resulted in 342.226 HP or a gain of 13.289 HP. Not bad for five hours of work. Oh yea, they lifted the limiter too.
I have plans to drop S54 CSL cams into the engine on my next trip with the CSL airbox and installation of Evosport Headers and race cats. This will complete my engine tuning and I'll then focus on the suspension in time for a nice summer up at the Nordschleife.
