Kelly-Moss Motorsports is developing a 928 motor for racing. Apparently they plan to put it into a 944 chassis. Crazy. Here is the blurb from their website:
This power plant has been one of the top priority's at KMR for the past couple of months. The 928 engine has spent many hours in R&D to make it one of the best all aluminum V8, 4 cam, 32 valve engines ever. Along with plenty of other modifications the EFI Technology engine management, custom stainless exhaust, and individual throttle body injection make this beast roar. This 700+hp engine will definitely get some serious attention at the track.
