    I never knew SHM made underdrive pullies, how do these compare to Steeda?

    IIRC....back when I bought the SHM pulleys, the Steeda balancer was a smaller diameter.
    I didn't want to go to such a small diameter.
    Now the Steeda pulleys look the same as my SHM pulleys.

    I cannot believe this is still FS. A must MOD for a N/A guy looking for cheap HP.

    I put an under drive crank pulley on my '98 GT - didn't affect anything negatively from what I could tell. Did it help? Dunno.

    Here's what they claim:
    •SFI Approved
    •8 - 10 RWHP Recovery
    •Improves Fuel Economy
    •25% Reduction in Parasitic Accessory Drag
    •Exceeds OEM Material Specifications

    Slowing down the crank, water pump and the alternator pulleys does reduce parasitic losses in relation to RPM.
    (If you have a big thumping stereo, you may not want these.)

    I have a Steeda pulley. It was accidentally free when we discovered it on a car getting a Trilogy and needed a stock balancer. Mine was the donor. I increased the idle RPM ~300 after the install. I think the Steeda is a 15% decrease in accessory drive.

    I believe all these claims are correct.

    You'll need to adjust your idle speed via a tune.

    is to kill them, keep on killing them, until you kill the last one, then you kill his pet goat."

    “Be polite, be professional, but have a plan to kill everybody you meet.”
    "I come in peace. I didn't bring artillery. But I'm pleading with you, with tears in my eyes, if you **** with me, I'll kill you all"
