Ive never seen any of a BMW flywheel thats come apart, only jap crap

[rob_htid]

a while ago on here i was reading a thread about lightening standard flywheels and someone posted a few pics of other cars that have had to much taken off and had broken up causeing them to rip out of the bell houseing and bonnet and through the rad etc - quite interesting i was just wondering if anyone knew where that thread was

thanks rob

It was a vauxhall Calebra i think.



And a 2.0 track Nova




Vauxhall flywheels must be made of monkeymetal

that smashed it's way through the chassis rail

I have heard of the castle nut's brakeing up and causing the fly's to come off/brake but not anything like this before

[johnl320]

Thats the ones I was thinking of Dan, but the Nova is as well

Was quite common back in the early days of motorsport, when machining wasn't as accurate, balancing wasn't as accurate, and there was no such thing as computers to analise stresses. Many a driver lost feet or legs to flywheels that broke up, sawing their way straight through the bellhousing and trans tunnel.

Fairly rare these days though, but as the above show, can and does happen occasionally.

Even a lightened fly will be fairly heavy and if it lets go at very high speed, think of the inertia it's carrying!

thats some serious damage possibly the worst thing that could happen, i mean what other single thing can write-off a car like that?

Well yes I know it's carrying a hell of a lot of energy, It was asked before weather it could break through the transmission tunnel and injure the driver... I think we have the answer if it can smash through all that then the relativly thin metal of the tunnel would not be much protection

Kevlar gearbox padding is available online

This is both amusing and rather horrifying at the same time!

on an e30 the clutch is about level with your feet so its going to hurt if the flywheel gives up at high speed

looking at those pics there have been some very lucky drivers not to have lost feet etc

I would quess that the flying fly' would take the path of least resistance,so would bounce off the tunnel and go onwards and upwards..

Does anyone know the facts behind these accidents? Were they home lightened or professional? etc etc etc

90% of broken flywheels seem to be jap going off web info

[oze30]

look at all the links from the ones I posted. Most are rotaries going BANG!
