    • Photos of First Set of Upgraded X5 X6 M S63/N63 V8 Turbos/Compressor Wheels by ALSA

      ALSA Automotive Engineering sent BimmerBoost details on their turbo upgrade hardware. Stage I consists of modifying the stock turbo's compressor wheels to allow for up to 1.8 bar of boost.

      Here you can see the pictures of the hardware and the difference between the stock X6 M compressor wheel with the modified wheels. ALSA believes they are the first to have the completed hardware even though Nowack claims to have upgraded turbos. Nowack has not posted any photos of their hardware or any dyno graphs. The same goes for RDsport so it clearly seems ALSA is the first to have upgraded turbos available for the twin turbo BMW V8's.

      ALSA is currently installing these at their facility for $18,840. Certainly later on we can expect these to be available world wide. ALSA will be sending BimmerBoost the dyno graphs shortly to substantiate their power claims as well as drivetrain loss claims. Here is the full press release:
