The test subject would be the Bronco. I was looking at undrive systems for the Mustang, which naturally turned back to implementation on a 335series. Which then progressed into a serpentine system, which I've heard about but can't seem to get many details on what was used. So...
1) So starting with underdrive pulleys for for a 335 series. I'm probably over simplifying this...but wouldn't it just be a matter of finding a proportionate percentage of the diameter of the original pulley? If so, is there a magical ratio for the decrease? And I wouldn't think all the pulleys would have to be decreased the same amount would they (ie, I see the crankshaft pulley being the biggest issue to support the proper number of belts). My thought process is if you can find pulleys in the appropriate widths and the appropriate diameters, this could be accomplished. I'd also think bolt pattern would be an issue, but couldn't those be redrilled?
2) A serpentine system for the 335 series. Again, I'd imagine the tough part here is cross-referencing for the appropriate diameter pulleys. Does the appropriate diameter change due to a serp swap? And a tensioner pulley would have to be implemented as well, correct? I have the idler pulley/bracket for the A/C system still, could this be utilized?
On both of these systems, I figure spacers could be utilized very easily for the alt and P/S systems if need be. As for the waterpump...instead of spacing the pulley out...would it be possible/prudent to get a block of aluminum and machine the necessary passages? And that leaves the crank pulley being the only pulley that needs to be nailed to perfection in my mind.
3) If I were to go full serp, why not go an underdriven serp setup?
4) Which would be the better setup to go with and/or do both? Only flaw I can think of with a serp system is if the belt breaks you're dead in the water. The flaw with the underdrive is a potential drop in alt output (but I don't have many doodads drawing much power at all) and maybe low rpm water flow (so bump to a premium wp from FlowKooler).
Thoughts and opinions???????
