GEARBOX BRACE

GEARBOX BRACE
If I understand this brace was designed because of vibration transferred from 5cyl motors to gearbox breaks the box?
Or would the brace be recommended to any other conversion on the Syncro with engines more powerful than original?

RE: GEARBOX BRACE
This brace was also for strength as well as vibration. On a 5 sylinder the engine mounts are not in a balanced position so do put extra strain on the back of the box under acelitation. Not necessary on other engines if engine mounts are placed in good positions.

How do you know if your engine mounts will cause strain on the box?

RE: GEARBOX BRACE
thing called trial and error, easier to fit one in case,

I may be a mechanic, but i can't fix stupid
Bad planning on your part does not make your issue an crisis to me
Bad workmanship by other garages does not entiltle you to better rates at me
Syncro, syncro , syncro and more syncro, this is the syncro way of life

RE: GEARBOX BRACE
Yes, basically the engine should be close to being balanced on the mounts. So mounts roughly halfway along the engine length will reduce stress on the gearbox/engine interface.

I was told by the development engineers at VW when I fitted my V6 that the gearbox brace was necessary with the 5 cylinder engine because of that engines high 2nd order vibration in a unique rocking mode which causes flexing in the gearbox casing. They said it would not be necessary for my V6 or most other engines.

RE: GEARBOX BRACE
i needed one on my TDI, torque and vibration was loosening the bellhousing, braced fixed that hassle

RE: GEARBOX BRACE
I should have specified petrol engines. I think with a diesel engine conversion it is definitely worthwhile. But more because of the type of vibrations than the torque as far as I understand.

RE: GEARBOX BRACE
Never needed one on the 25 plus TDI's I've fitted.
I am also running 190bhp and 300nm on my 1.8t and don't need one.
