    Default Light weight fly wheels ????

    LIGHT WEIGHT FLY WHEELS

    What are the pro & cons of using a light weight fly wheel on a 4age 16v ???

    Engine is in a sprinter ae86 --- used for hill climbs . motorkhana and the odd sprint. Slightly warm engine say about 90kw at rear wheels.
    Will putting a fly wheel that is half the normal weight help or hinder ????

    As far as i know know it will help, otherwise why on earth would all these brands make them?
    Lighter flywheel put less load on the engine, therefore it can rev much more 'freely'

    compared to a stock fly wheel the lighter you go the less torque you get?

    Lighter for hillclimb orientated vehicle (read street), not recommended normally, but motorsport you will be wringing its neck anyway, so highly recommended.
    I run a Toda 3.7kg (Measured to be 3.65kg) flywheel on a stock silvertop 20V and think its one of the best mods I did to it. Suits me. Fantastic on downhill stretches.
    Overall weight of the assembly was 7.5kg, which turned out to be the similar weight of a stock small port flywheel.
    On the street, you may have to downshift to climb hills.

    Yes, less inertial mass, and in turn angular torque.

    you dont lose torque just inertial energy buildup ability.

    I went from the 6.9kg silvertop flywheel to the 5.9kg blacktop flywheel, the figures dont tell the full story though as that 1kg is taken off the very outside so the two are quite different. Strangely enough I didn't notice much of a differece driving around but I did when taking off, I found it very easy to stall. This problem was tottaly taken care of with my aftermarket ecu though. now that my engine is running nice I should change it back with a quick gearbox swap at the same time to see how it is.

    i run a 3.7 kg one from dave. it's pretty good can't really fault it. my old one was 7.4 kg. It's a bit more responsive but it's didn't change my life. Might be different on a N/A car. it's pretty cheap too so it's well worth it.

    heavier flywheel means more rotational force keeping the wheels turning??

    is that what u were thinking sam?
