I do not recommend them at all

What are your current mods? Gears or exhaust or shifter should be the first mods you do.

they are a good mod i think just get the steeda ones....

if you want them get them. they are fine for small hp gain, make sure you have the right tools for install or u r screwed.

The potential problems caused by them are not worth it to me. I'd do something else unless you are looking for every possible pony.

The install is critical, it must be done right and is not as easy as sometimes assumed...

it is as easy as everyone assumes. just cant do it with a socket set and screwdriver, need the correct tools..

I have heard that every once in a while, the right tool can make a difference...

That's because you're Capt America! But tomustangs could do it 2.43x better than you

They are fantastic. A proven mod since day one. AND THEY SAVE YOU GAS! WHY ON EARTH DOESNT EVERYONE WHOS NOT FORCED INDUCTION HAVE THESE THINGS.

Sorry it drives me nuts hearing folk who dont have them saying they are bad. Much better than plenum/tb and they improve your gas mileage. They pay for themselves!

they are a good mod...alot of guys will tell you they are not a good modification because some morons have not done the install right and screwed up their motors. read the instructions and do the install right and they are very good and cost effective mods.

well I think they are a good mod..
I did them a few months ago. I made sure that the alternator wasn't undercharging too much and it wasn't. It's decently easy but you do need a few tools to do it. I remember that switching the alt. pulley was a pain because of the lack of room ( I didn't bother removing it) and the swivel impact socket was not swiveling as much as I needed...

But I have noticed I am using less gas as well it gallops a little faster after too... just enough to actually notice...

deftsound · May 2, 2006

what kind of problems could they possible cause?

Orange... · May 2, 2006

the main thing is when you have a powerful stereo or something that it will drain the battery significantly, the alternator can't keep up because it's being spun slower (especially at idle).

Even with the stock mach460 and the a/c going I notice it will dip enough on mine.. I can't imagine someone with a large stereo....

Some people compensate this with keeping the stock alt. pulley on, but if you do that you are losing 1/2 of the h/p you paid for buying the pulleys... so what is the point?

imblown-ru · May 2, 2006

some people will tear up the motor somehow by screwing up the crank pulley...it has happened so few times that i dont even know what goes wrong...just do the install right.

I use to run the steeda ones on my cobra, they made a little more power. I left them off when I had my new engine built because I want to keep my car running cooler.

02FastblackGT · May 2, 2006

Yeah, I heard that the pulleys are a good mod. They are usually good for 5-10 hp & 7-15 ft lb tq. Plus, low-end acceleration is increased & gas mileage too!! Only negatives I have heard are the lack of voltage to power the accessories: a/c/stereo, etc... and that the install is tricky. One thing I have learned (even from only having my stang for a few months now): having the right tools and the right instructions, you can do almost anything to these cars. I'm gonna get the Steeda pulleys, hopefully very soon.
