Can these two work together and is it worth it? I have FRPP underdrive pullies and I have been thinking about an E pump. The E pump has an idler pulley on it that I'm almost positive not the same size as the water pump pulley. It looks smaller in pictures. Will a shorter belt fix this and what size?

yup........ i think you need a belt that is two inches shorter. Make sure your underdrive pulley are not piggy back. I highly recommend it, its very nice and quit and keeps every nice and cool.

What do you mean "piggy back"?

Piggyback pullies like Josh was refering to are at high risk to break the belt prematurely.

Steeda - Not Piggy Back
BBK - Piggy Back

Well, I have this...

Which is funny because the FRPP website now says they are for 96-98 and I have them on a 99. When I bought them back in 02 I rmember it was for 96-01.

The BBK looks like this...


and the steeda looks like this...


I can't tell the difference other than the center looks un coated. As usual, Ford Racings website has about enough information to be dangerous. If I remember correctly, mine looked more like the Steeda and it didn't feel solid. Steeda's website says theirs is nodular iron and injection molded rubber where the BBK looks solid. Like I said above, I've had mine on since 02/~30,000 miles and I have not snapped a belt. Anybody know for sure?

josh.davis

yeah dude you have piggyback, do a search on piggy back; There is alot of information there.
