im looking at underdrive pulleys but dont nkow which to get. the bbk pulleys say they unlock 10-15 horsepower and the steeda pulleys say 5-10 horses unlocked. whick is better quality and which is telling the truth.
I also got the Steeda's for $75 which made me even more to want them. Yeah the 10-15hp gain is more like 5hp or so. Steeda's are the best for our stangs, they worked with ford to design them especially for our cars.
