    Default Flywheel lightening

    I consider to lighten the flywheel and found this thread: http://www.guy-croft.com/viewtopic.php?t=570

    Do anyone of you have experience from lightening the 155 Q4 flywheel and have any advise to share?

    Unfortunately I'm far away from that stage of tuning which needs to lighten the flywheel, and probably never get there. Are you aiming to tune your car to reach that 7.5k rpm ?

    Well, I am rebuilding the engine completely and put in very light forged JE-pistons, so while having everything out and considering what could be done for small money to enhance the experience even more, that was an easy one. I already have the revlimiter at 7048 rpm with stock internals and maybe the new rotating assembly could take a little bit more, but the injectors will not provide more fuel. So I probably don't raise the rev limit.
