Piggy back UDP's

Novanutcase · July 18th, 2008, 03:52 AM

What are the pro's and con's to these types of UDP's versus, say, a set of Steeda UDP's? I'm thinking of going with a set of these:

i dont know the pros to those, but dont get them. i asked the same question way back when, andi dont remember why, but dont get em, get steeda if you really want udp's. I got em

Yeah but why? They both seem to do the same thing which is running a smaller diameter pulley which is easier to turn. Kind of like a lightened flywheel!

Thanks! Still not sure! Some say they're OK and some say no. Do you know if the ones in the pic are piggyback or not?

They are bad because the crank pulley/balancer is the external balancer for the engine. You start bolting thing onto it it starts to mess with the balance. Steeda worked with Ford to produce an underdrive crank pulley that has a balancer built into it. They are the best to get.

I have the steedas on my car and i put bbk piggybacks on my buddys bullitt and have seen no adverse effects, as of yet anyway. But having installed the 2 the steedas is wayyy above the bbk in my opinion.
