I'm just curious, on a fairly well modded SC like mine...

What kind of HP do you think aluminum pullies are worth.

Assume aluminum underdrvies, alt, WP, crank, JS, PS, and SC pullies.

Who thinks the whole set is woth more than 20hp.
 
BTW, is there any aluminum water pump pulley that will fit with MP 10% crank pulley?

I remember I saw somewhere...

I have seen 12rwhp on mustang 5.0's with the use of UD pulleys..I;d have to say somewhere in that neighborhood
 
Weight may play a role in power gain however at high rpms less drag due to spinning accesories does as well.....Get aluminum if you can
 
In reality only the water pump pulley is steel in the sets that are not fully aluminum. Both my brother's and mine came with aluminum crank and alternator pullies.

David, he has jackshaft and SC in there as well. If they are Overdrive, then there should be more than 15 hp gained.
 
As has bene said only the water pump pul;ley is steel most likely so it wouldnt be worth it in my opinion..My ASP underdrives were l;ike that
