Are these any better/worse than MT's steeda underdrive pulleys? They cost less, but is it just bc its not steeda, or do they not give the 8-10 hp that steeda claims? A little insight would be helpful

 

I've always heard that the March pullies piggyback and you DON'T want that

 

I've heard the same thing.

 

I think March makes both both styles, but I think they non-piggyback style cost just as much as steeda.

 

I installed the steeda pulleys,I never dyno tested before and after install but the seat of pants feels like 5-10 horsepower. The steeda pulleys came with great instructions and all necessary bolts and had a beautiful stock looking black durable finish. The first thing I noticed after the install was the power steering is much stiffer at idle and low rpm,s now. I believe the steel material that steeda uses will far outlast a hardened aluminum alloy that March uses.

 

1st of all if your gonna get a supercharger, dont waist your money on the u/d pulleys Now.But if you must get them , then get the steeda ones. Thats the only way to go believe me. i have them and I'm happy with them. No problems so far

 

Do any of the pullies really make any difference or is it all looks?

 

i see all the time if you are getting a supercharger not to get u/d pulleys. why is that????

 

because they change the rate at which the belt and acsessory move at (rpm wise) so when you add a blower you need stock pulleys so you get the correct boost. other wise it will be i would imagine alot lower boost.

 

Lol yes they add power. I dont really see how they would be considered a appearnce item but yes they do add hp by slowing the accessorys down. had them on my f150 they dropped me i think it was 1tenth was it in the 1/4.
