Does anyone have a g16 crank pulley handy? (the one that runs a serpantine belt) I need to know what the dia of the g16 one is.

If you look at the pulley (ascii art below) from the side you can see the grooves for the belt. I guess if you measure from the apex of one of those (eg, the '/\' bit) to the same on the other side. If I do the same on the other pulley I have I should be able to calculate the drive ratio.

when calculating drive ratios do you need to take the mean diameter? ie from middle of the valley to middle of the valley?

Dunno. If the height is the same on both pulleys it shouldn't matter. Might do some sniffing around and see what I can find out.
