    I've heard it reduces torque and reduce the ability to go up hills. Is this right? [:s]

    just have to keep your revs up when pulling off prone to stalling

    Technically no, but the extra engine responsivense, up and down gives that sort of feel.

    putting it simply, the engine will rev quicker (causing the car to accelerate quicker) but it will also decelerate quicker too when you let off the throttle.

    I'm having a lightened flywheel put in soon, do you notice it much?

    Probably need to get it balanced together with the crank to make a proper job of it. Have heard about poorly balanced lightened flywheels snapping cranks :o

    The standard cranks are pretty spot on to be honest. As long as the flywheel has been balanced to the pressure plate on a 020 or just the flywheel on an 02a you'll be fine.

    Having worked in the car assembly business for a few years, it's worth noting that cranks and flywheels aren't normally matched or balanced together in run of the mill production engines.... and pressure plates are pulled at random out of a big box.

    So as long as the lighter flywheel is balanced to itself, the rest should be fine.

    A lightened crank might be more susceptible to vibration, but a standard one should be fine.

    well worth doing in my opinion.

    You don't really notice any downside to be honest, it just pics up very quickly in the first couple of seconds of acceleration. The loss of torque you are talking about has something to do with inertia, but not being an engineer i don't really know what that means! As far as i see it, any negative effect of not pulling up hills quite as well would be countered by the fact your revs will climb quicker and hence you'll have more power to climb the hill!

    i would expect the negative,s would be felt more in a heavier car. ie the later models.

    66. That sounds pretty good. Was that just to balance/lighten or included removel/fitting. I presume the former is the case?

    Agreed, although mine was 68, cost of inflation or something I guess. :lol:

    So if its just for the work and not the removal and refitting then I need to get mine off.
    So...
    where is it?
    What does it look like?
    How does it come off?
    How long will it take me?
    How long does it typically take someone to turn around the work?

    It's a daily driver, so all this stuff is pretty important!
