With all the excitement over the rather sedate 500hp GT3 Smiley I thought I would share this pic of my engine at its peak power during a 1 minute 35 second full power dyno run with 22 seconds from 6000 to 7150rpm, hence this is rare amongst the amateur tuning world of 8 second power runs.

This engine is basically the same as the Alzen Mission 400 engine (mine runs less boost, about 1.2bar and variocam) so it is special build 3.9 litre with proprietary RS head preparation running latest K24 type turbos and a new factory electronic controlled electronic wastegate system (borrowed from the latest generation BMW system)

Its return to me has been delayed by the very cold and bad weather southern Germany has been experiencing has made testing impossible however it should be back soon.
