chris I already sent you a picture of the crank it is the same in that engine also so the answer is it is very controversial to say the least as I have said. The turbo flute enters the tunnel and according to a quote rule clarification mid last year roar is calling this illegal. Even though it states that the crank bore shall be no more than 7mm, and does not state the length of that 7mm bore,however they still ruled it illegal on the 12's. It states the length very specifically for the 15's in (note2)It is still not written anywhere but I know first hand you will catch heck as my gen 1 cranks looked similar only biturbo.
depending on when and how roar blends this with ifmar's new rules for 200MM it may become legal. time will tell that.
