    ECS Tuning Presents Quick Spool N54 Pulley

    ECS Tuning Presents ECS N54 Quick Spool Crank Pulleys


    The ECS Quick Spool Pulley releases hidden horsepower from your N54 engine by reducing the rotational mass caused by the stock heavy crank pulley. Less rotational mass equals less engine drag causing the engine to have a quicker throttle response creating boost faster throughout the RPM range.

    The stock pulley weighs in at a scale tipping 8.65 lbs. compared to the ECS Quick Spool Pulley at just 0.50 lbs.! That's a 94% reduction in weight.

    This is great for cars with no supporting mods, but Enrita had one installed when his engine blew. I believe he switched back to the OEM pulley after that event.

    Is this Dampened?

    I believe this was the big question for other pully manufacturers

    By the looks, and weight, it does not appear to be dampened.

    I don't believe the OEM its damped. Seems to be 1 solid piece.

    Ecs, can you guys provide some high detail pics of the OEM pulley?

    How long is a typical DIY install?

    I have not heard of a single person using this. Just like the aFe throttle body spacer.

    People use them on other platforms. If it is not dampened I would be slightly concerned...I mean you can always be the guy who buys it and a new belt and tell us what happens.

    yeah i was looking at that also, i remember the throttle body spacer being a must do mod on the 350z platform when I had one. This looks interesting though, someone had to have tested the thing.

    Many N54s did a few years ago. A small percentage subsequently had camshaft/VANOS failures. So light weight N54 pullies proved to be unreliable at best.

    The throttle spacer is just an outright scam.

    The ones that did not have issues with the pulleys, were there any gains or any added benefits?

    On the N54, the problems with a pulley simply don't outweight the possible problems (camshaft failure = $$$$), especially cause you could outpower the potential gains by changing the boost curve or adding a few degrees of timing. It's not like the S65 where people do pulleys to squeeze out a last ~10-15 WHP when staying N/A

    The OEM pulley is a harmonic balancer, why would you remove it?

    RealOEM calls the OE pulley a "vibration damper" and they are different for manual and automatic cars (11237572788 vs. 11227558083). They are also $563 a piece (I $#@! you not). There is probably a little more to it than just a way to transfer motion from the crankshaft to the accessory belt. I suspect there is a very good reason the stock pulley weighs "8.65 lbs."

    STAY AWAY from this pulley upgrade Click here to enlarge

    B-A-D...OEM is not just a pulley, it is a harmonic balancer and I've heard of at least 2 people having bottom end issues after using it (no harmonic balancer material)..not worth the risk at all...NST was another company that offered it..
