Cooling fan ?, Anyone know the degrees per blade? Options

[ottox914]

Messing around with some updates to the 914, no problem finding TDC, but my other timing marks are hard to find. As a means to double check my work, anyone know how many degrees per fan blade? Yes, I've tried Mr Search to no avail.

Good answer dave, but not exactally what I was looking for. I was probably a little vague, so I'll try to ask again with more info- I'm installing an aftermarket efi system, (I'll post details once it runs) and don't need to know where the stock timing marks are. I know where TDC is, but need to set a base timing different than a factory referened mark on the fan. As I know where TDC is, how many degrees are referenced per fan blade, so I can approximate where and what my timing is being set at, since I don't need/can't use the factory timing marks?

actually, Daves answer was spot on (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

what you "you" need to do is print out the template (make sure it's 1:1) lay it on the fan and measure how many degrees from one blade to another with the template...measure the diameter of the fan and just do the math...Dave Hunt also posted a link to a downloadable degree wheel that'll help with the setup as well....
