I can't seem to find any from March or ASP. ASP has listings for early 4.2s but not the 2001. Does anyone know of a maker of underdrives for this application?

Thanks,

 

As of now the only underdrive pullys are for the 97-98 4.2. But ASP is currently reasherching a 25% underdrive crank pully for the 99-new 4.2L. To my knolodge it is not sceduled to be relesed untill at least another month(I think)

 

Now, what would make the 97-98's different from the 99-01? New at this pulley stuff, but I'm sure I will be getting a set in the near future.

Talked to ASP yesterday. The reason no pullies are available for 99-01 yet is because Ford changed the crank pully in 99. The 97-98 4.2L pullies were identicle to the 3.8L Mustang pullies. They believe they have since found a method of producing the 99-01 and will consider making it. They are taking contact info of interested people. If enough of us ask for it they will probably produce it.

 

Happy News for me,(97) but what kind ok performance gains can I expect with the pullies. Is is noticeable? are there any numbers? Is there a website? Please let me know, I have been interested, but didnt know where to look. Thanks

 

I did alot of research on the pulleys and there's a few folks here that have it too.

It basically gives the engine a bigger "turn" then you had before, unfortunatly sacrificing are the water pump and alternator? (not sure which else suffers) but if you drive in traffic, you have a chance of screwing your truck (overheating)

go here and read about what it does and is exactly, it helped me out

the results were noticeable, but not drastic.. I did'nt hear anything about "seat of your pants" feeling..
Higher gear ratios will give you that, and so will a supercharger

the guy who writes that article has good things to say about it tho-
