Stock Crank Pulley Size

[scott r]

Hello again folks. Does anybody know the size of the stock Crank Pulley on the 2003 Sport Trac? It's rather difficult to get a ruler/tape measure down in there to measure it, so instead of spending the rest of my afternoon out in the cold, I figured I'd ask here instead. Hopefully somebody knows though, otherwise I'm going to have to go out there later when it's even COLDER!

I should also have a new video up this week of the supercharged trac, so keep an eye out here at the forums. I have put the Pioneer AVIC (Advanced Vehicle Information Computer) in my truck, and it shows horsepower/torque as well as lateral Gs and some other cool information. That's all for another post though.

I sent Todd Z a pulley from a scrap engine. Check with him as he will have it in his hand...

It's not a secret, but it's not data that's easily obtainable either. I needed to know it to work up a ratio between the supercharger pulley and crank pulley so I could figure out just how fast the supercharger is spinning, or how fast it would be spinning if I went to a smaller supercharger pulley.
