    Different flywheels give different idle and pick-up characteristics. I always go steel flywheel, and never had issues. I did go alloy once with steel insert and yes it was slightly noisier, but that was with a paddle clutch. Its something you need to consider. I have always noticed a difference in pick-up but it depends how light you go.
    Its not a power increase, its a reduction of parasitic loss, the same as under-drive pulleys. Some work to good effect and some dont/or to a lesser degree. Underdrive on my V8 and you gain around 15hp, so its worthwhile. The other benefit is if you are running at high rpms for long periods, the under-drive will return your driven items to within spec speed.

    Both changes must be a considered decision/choice.

    i am look at less engine drag was thinking doing the pulleys and fan delete at the same time ? i think the chatter from the gear box would piss me off a little t0 much

    You dont get chatter with the correct selection of fly/clutch

    I'd agree with markrnorton that if you choose the correct flywheel and clutch set up you'll be fine.
    The flywheel on mine is alloy and 3.9kgs, it is over kill for a daily driver. For a car that will see a bit of time in traffic i'd go with something heavier and steel.
    The reason for the difficult driving characteristics is the clutch and pressure plate setup. This could also be changed for something more suited.
    I don't believe that you've gained 15hp from the pulleys.

    I dont really care for people who talk but dont do. I have, have you done this ??. America V8's are notoriously under engineered, you dont need to do much to increase power.

    just one example - http://www.troyerperformance.com/cgi...talogno=528774

    But we're way off OP here
