    Underdrive pulleys are a waste of money.
    I didn't feel any gain from them.
    Spend your coin somewhere else.

    really, cuz I thought they helped quite a bit on my bros 99 gt. we installed them in a few hours besides the fact that we had to locate an impact wrench lol. I wanna get some for my car though. It revs a lot faster IMO bc of the reduced drag on the belts.

    BBK, Steeda and March make good pullies. I have BBK on my car and noticed a pretty decent gain. Especially towards the top of the tach. If you plan on just staying "all motor" then it's a good investment.

    I bought March, must admit, good quality, not sure about any power gains but they look great. :)

    Eh, it's my personal preference to stay away from the piggyback style.. seen/heard too many bad things and that's how I ended up with steeda's... Plus they are SFI spec..

    If you're going to run them,get the nitrade steel ones,because the aluminum eventually wear and will fail.........my steeda water pump pulley imploaded after two years of driving,and left me stranded in a parking lot :comando: Gains are like 10hp at best,but if you're staying NA,it's an option at least. If you're radiator is old,you will notice cooling issues in the summer.......and they're not "system" friendly at idle.

    If you must have them, Steeda and nothing else.
    If I were to do it again, I would have spent the money somewhere else.

    I picked up 8 rwhp from my steeda's. I spent a womping 130 bucks on ebay for a power gain of 8. I would say worth it? YES

    I was shopping for a used set a while back, and decided against them mainly because of all the troubles I read about with charging issues and also cooling issues after installing them. The solution to charging issues was just to skip the alternator's underdrive pully since it didn't contribute to gains much anyway. The cooling issues I never really got any straight information on. Don't know how it's caused or what can prevent it. I do have a few questions though, since this seems to be the appropriate place to ask. What exactly is the "piggy-back" style? Are the claims of having cooling/charging issues warranted, or due to other factors? Solutions?

    "Piggyback" style is where the stock crank pulley is bolted on with the new underdrive pulley and put back onto the car..
    Whereas non-piggyback, such as steeda, replaces the crank pulley with an entirely new pulley.

    I had Steeda underdrive pulleys and after the install my mustang
    would run hotter no matter the season or weather.I didn't notest any gains so,
    I simply wouldn't waste my coin on them and spend my coins elsewhere.

    Both claims of poor charging and cooling are very warranted,mainly the cooling,but guys with systems,and a lot of aftermarket accessories,hate them most. Skipping the alt pulley helps the charging issue,but it is still kinda present.....because the smaller crank pulley still turns everything slower,so at idle the voltage regulator has to work a little harder than it normally would. (but it's still better than with the UD alt pulley)

    There's no good solution for the cooling issue,because no matter how you dice it,the waterpump will always be spinning 40% slower than it normally should......slower means less coolant going through your engine,which means more heat. If your car is already modded,it's even more noticable.

    Ford did it right on the 93 cobra..... they use a traditional sized UD crank pulley,15% UD Alt pulley,and a(smaller than stock) Overdriven waterpump pulley, to bring the waterpump back up to it's normal operating speed. It was a perfect balance....too bad no other company saw the benefit of it. :dunno:
