I have found in my searches that the 7.3 liter F250s come with an 8 rib serpentine belt system. The main part of that system that intrests me is the crankshaft pulley because I am looking for something I can pull off a junkyard vehicle (or car-part.com) and adapt to mine.


The crank pulley i have now is only 7" in diameter, which necessitates the use of rather small pulleys on my M90 to get my target boost level of ~12 PSI (i'm using a 2.5" blower pulley now)

If i can find an 8-8.5" crank pulley I can use a 3" blower pulley to get where I want to be. I made this one by welding on the backing section of my taurus crank pulley to the 8 rib outer section of a supercoupe crank pulley, i dont mind if i have to cut and weld again.

I guess I just need to know what size the stock crank pulley is for the 7.3 engine in your vehicles, also any pictures of that would be nice.


thanks in advance for your time,
Craig

 

ttt anyone got an idea?

 

My 96 PSD has a 6.75 dia crank pulley. It also looks like it is integral with the harmonic balancer, but I am not positive.
