    Less Rotating Weight = more power in a very general sense...

    Thanks for a normal responce. dont seem to get that alot on here anymore.

    So i guess its normal that I feel a change in throttle responce?
    Just seems like the rpms are rev hire. I dont know maybe just gota get use to it. hope this was a good choice in getting.

    thanks again.

    No Prob. man, I could believe you would get quicker rev up this fore if you if you install a lightweight flywheel you will get quicker rev up. If anyone makes them the best its prob. Perrin I believe in the whole motto "you get what you pay for"

    He's right you know. Purchasing a part and THEN asking questions about it is extremely stupid, and a good way to ruin a car.

    Love the Perrin Pulley

    I installed my lightweight pulley a few months back and immediately noticed the difference. Better response, quicker revs. To me, it's the poor man's lightweight flywheel. Highly recommended!

    You can't blame a compass for pointing north.

    Better response, quicker revs (I supposed you mean in a upward direction) but how about when letting out the clutch or between shifts? Does the lightweight pulley that is lowering rotational mass affect how the engine handles shifting? Does it enable you to do quicker shifts? Does it reduce the 1st to 2nd wait time by 10 minutes?

    (That last one was a joke, but seriously...)

    I would have to agree with this, with the lightweight pully, no harm, no foul. But if you plan on any other mods, it would be in your best interest to research before you buy. These are not hondas

    +1. As edgy as Matt's comment seems, I would take this to heart.



    The LCP is a "poor man's lightweight flywheel." While you will get slightly better throttle response and theoretically more power, I am convinced that the effects on the butt-dyno are largely perceived by placebo. At the end of the day, a 3 pound reduction in the crank pulley is less than a 10% reduction in rotating mass. It does make difference, but less so than we "feel."
