Hi Guys,
I give you some news about my Z4 development....
We hit 445hp @8500 rpm!!! we make some work on the head engine (RV ratio, exhaust flow, intake, camshaft, cams...)
We make a step by step tune and increase in power, as we don't want to break the engine! We have a real hope to get 480/500hp @9000/9200rpm...
I will make some photos/video/dyno shoot asap
Stay tuned !
