Hi all,
Just to let everyone know the sirio crank part no. s12 081200 is for the non-turbo crank and part no. s12 081300 is the tubo crank.
On the sirio website it shows a picture of the turbo crank againt part no. s12 081200 (which has been pionted out to me).
Shiston,
Actually both are Evo2 turbo cranks the difference is that:
PN° S12-081200 is the EFRA version of it (no chamfer on the outlet hole and the scoop doesn't meet the outlet hole).
PN° S12-081300 is the IFMAR version of it (big chamfer on oulet hole and huge scoop that comes from inside the crank flute).
PN° S12-081100 was the old style non turbo crank for the Sirio S12TRP/R
Hope this clears the issue
