There hasn't been a set of pulleys that have been named superior the the other. I, as well of most others like the ASP designs because they are aluminum and lighter than the stockers. They haven't been proven to produce more power than the FMS or March pulley sets.

I bought a set of Mr. Gasket underdrive pulleys, what could be so different about underdrive pulleys? I can understand maybe the weight but wouldn't every company have the largest possible circumference for maximum power? Should i sell mine and get some march or asp?

I think what you mean is the minimum possible circumference. The crank pulley is what produces most of the power, and you want that to be as small as possible. Anyhow, no, I wouldn't sell your pulleys. It wouldn't be worth it. If you were to pick up any power, it would be less than 2 horsepower.

i have MAC's and i like them, was definatly a noticeable difference in power. i havnt tried any other brands but i dont think it would make all that much of a difference

I beg to differ with you Joe. I have seen better gains from ASP pulleys than any others. I went from 14.96 at 91.5 to 14.5 at 94.89 with nothing more than ASP alum. pulleys. I have not seen that from any of the others. If you have, please correct me.

Do U.D. pulleys work with the stock belt size?
Right now I have a short bely to bypass the smog pump.

Just wasn't sure if I'd need Another belt

Thanks.

Yes, 99% of the UD pulleys on the market for mustangs use the stock belt.

I chose ASP and I was very happy with the results, althought I can't compare to others. You can find them for a pretty good price too.

Paul, you could be right. What I meant (but didn't say) is that since all U/D pulley sets have all of the same sizes (circumferences), the only real power difference would come from the weight of the pulley because all the underdriven accessories are all moving at the same speed with a different pulley. I have personally seen a set of FMS right next to a March set and they were both the exact same, so those are the two that I am basing my comparison off of. If ASP pulleys have different sizes than FMS and MAC, then there is where the extra power is from. Otherwise, it is all in the weight of the material.

WHOA! After re-reading my post, I think some people would have a hard time understanding it. Sorry if you do, but that is the best I can do. I suck at describing stuff.

I LOVE my asp... Mac is just, in my opinion, a cheap A$$ company... no problems w/ my ASPs though, not really a charging problem, just dim lights at idle... I am running a little warmer w/ them, but really nothing too much to worry about, I just slap a 160 thermo in for the racing season, and manually control my electric fan and I'm fine...

only the crank is supposed to have a smaller circumference right? my alternator and my water pump pulley are both bigger then my stockers, is this right?

yes, that is right...

-and it is called paracitic loss, the power taken to move an object relative to a similar object at lighter weight... (physics major) (hey, I actually learned something in school!) YEAH!

I whould have thought that with the bigger alternator on the 94-95 cars that there whould be no charging problems. My old 91 LX 5.0 with asp's didn't like to charge much at all unless you were cruzing at 70.

well, having a smaller crank makes the belt move slower first, then having the larger alt pulley makes the alt turn even slower... so yeah, it makes sense...
