Anybody looking for a lighter flywheel?

[tinker-27]

just run a std ls7 clutch i have tried a light fly and it make very little difference not worth the bother, if the motor is put together right throttle responce will be very fast and the std fly give nice idle and smoother running, and they are for pennies !! sometimes std stuff is good !!

^ Tinker, by a strange coincidence I just happen to have to have standard ls7 flywheels and clutches in stock. They are light compared to sbc stuff!

One school might suggest not to read a numpty forum for technical info

Not really - nobody is denying that a lighter flywheel will have an effect. but for a road car (esp one weighing the best part of 2 tonnes) the effect is going to be limited more to engine feel rather than outright performance.

I think this was the OP's point. Nobody - except everybody on this forum - mentioned he wanted it for more power. On this forum we always assume more power....

For me, one of the things I don't like about the Monaro is that it is so lazy. I would love the engine to spin up faster, and lowering the weight of the engine internals would do that. I think that this is what the OP is after. If he wants more power then he'll do the other stuff he mentioned (new head, etc.).

Seems to me that he knows what he is after, but it also seems to me that we sidetracked his question into another conversation about more power......

Getting timing right makes a big difference on the rate rpm's rise.
The ECU is designed with non optimal timing at idle as it allows the ECU to advance or retard ignition to raise or lower RPM to maintain idle speed. If it was at optimal it would not be able to raise rpm with timing which would cause it to struggle with idle management....
Anyway, this can be alieviated to a certain extent and can make a big difference in how fast rpm's climb.

If you are not going to tune each timing cell for MBT then you shouldnt even be considering stuff like flywheels. Getting timing right is far more important IMO.

Agreed - you can also adjust the throttle pedal mapping. If done properly you can transform the feel of the car. The best one I have driven used some very nifty non-linear mapping algorithms that used a number of parameters (not just raw throttle pedal position) and was simply stunning. You didn't lose any throttle feel but a quick stab would blip perfectly.
