      Not really much point to be honest, real benefit is if you are revving the engine hard to get the power (N/A engines)

      You may even lose torque at the bottom end, although it will rev a bit better... money better spent in other areas IMO

        there must be a benefit of lightening the bottom end as vauxhall did a similar thing by removing the counter rotating balancer shafts from both the 20 xer homolagtion car and also the vxr engine and from my experience it worked really well on my astra gsi turbo and were not talking race car lightweight the new flywheel is only a fraction lighter than vauxhall were using on there engines in the mid eighties its just that the new engines are generally built as world engines and are therefore fitted with heavy flywheels to comply with emission regulation in far flung countries will find out a price

          I am not saying there is no point, there certainly is for highly tuned engines...

          Just not for milder applications for the outlay...

                the engine will rev easier low down but will loose inertia at top end. you could loose bhp but you will increse throttle response.

                not ideal in an already powerful front wheel drive car

                    lol, sorry

                    the balancer shafts where (apparenlty) removed to quiten the engine (according to courtenays website)

                      "Gone are the Z20LET’s counter rotating balancer shafts. This sharpens response whilst helping the engine rev much more quickly."

                        This could be one for the future when the clutch lets go, as g box will then be off any way, big job for a fly wheel i would thing.

                            I have experienced many lightened flywheels. Its not all about power, where the biggest advantage is the ability to balance the car on the throttle in a far more predicatable and accurate way. Gear changes are also found to be smoother, faster and response is lifted. Not really sure how you loose BHP, torque perhaps, what can happen is the trans loses found through the system are reduced and allows the power thats already there to be better utilised.

                              fly wheel is very easy to change when the box is off dave. clutch off and then about 10 bolts holding the flywheel to the crank. it doesnt disturb the crank seal so should only take an extra 10 mins.

                              i agree that it will be worth doing if your taking the box off anyway but i wouldnt see any real point in taking the car apart just to change the flywheel.

                              ive had them on my old fwd cars and tbh it just gives them a better excuse to spin. also, when you back off the throttle the car slows down alot quicker as it hasnt got the inertia of a big wheel. try driving in 1st and backing off the throttle (its like slamming the brakes on) its abit like this.

                              mine was a race flywheel though so maybe this was bit extreme.
