underdrive pulley question

[95gtdrop]

so im looking into getting somne U/D pullies for my cobra.
i have used them on all 3 of my previous pushrod motors, and noticed HP gains.
do the U/D pullies on the 4.6 4v give any gains, and do they affeect the temperature, and does it drop the alt output?
if its worth it, im going to go with the steeda pullies.

basicaly what im asking is if they are worth $ 200

I have ran them and several others have as well. No issues with charging or anything like that. BUT, make sure they are
put on correctly as the balancing is very tempermental on the Cobra 4V. Give a good read to the link below then decide.
You can go either way.

Please get the non piggyback style.. It doesnt gain you HP.. It frees up HP by taking it away from the accessories..

Otherwise I have never had a problem... Are they worth it? Not sure.. I have piggyback(Dont ask why).. and plan on eventually swapping them out for a better set..

what brand makes that type?

 

[Shifty Powers]

BBK..I have come to dislike BBK very much lol.. Well, theyr parts for mustangs are not that amazing.. minus their LTs are ok..

Ide get the steeda or March(not sure if they still make them)

yeah imo bbk is cheap. i am a steeda fan and was planning on getting those ones.

wait for used ones to pop up. i sold my steeda ones for like, 80.00 :-/ if they work for you, great. if they dont, resell them.

everyone has different opinions on UD's i had them, never had a problem with the ALT, but my car would over heat in the summers in stop-n-go traffic.

 

[95gtdrop]

Sounds good. I'll keep my eyes out for a set of some.

Im with chris on that one, I had steeda's on my old motor and got them used for under 100 a few years ago.

A local magazine did a write up with back to back dyno tests with under-drive and stock pulley setup, defiantly was a good read.

I will be putting these on my Aviator swap. These are the same pulleys as what came on the 00R's.

March 116 Alt. pulley
March 1172 Water pump pulley
March 1158-08 Harmonic balancer
March 640-08 Hydroboost pulley

This^^^ if you don't go with all those pulleys then at least get the March fluid dampner and mach1 alternator pulley. Another option for the accesorie pulleys is to go with Bullitt water pump and alternator pulleys. They are the same as the 96-98 cobra pulleys but bigger of course. But definitely get the March crank fluid dampner
