Diameter of Main (Crank) Pulley on S5 NA?

I'm doing some calculations and need to know the diameter of the main (crank, eccentric, whatever) pulley is on an S5 NA.

Thanks.

pulley diameter

S4 NA (and I'm sure S5 is the same), diameter is 361 mm. Makes it very convenient for applying degree marks to the pulley - when 1mm = 1 degree!

... Thats realation to cicumferance, not diameter.

Diameter is across, by saying 361mm, you say 36.1cm, or .36meters.... That means you're saying the pulley is over a foot across...

Circumferance is 361, pull out some geometry and find teh diameter.
