Engine mounts
Hiya all.
Wasn't sure where to put this (here or engine) but figured here would be better. Appologies if this has been asked before but I couldn't
find anything in search.
Does anyone know if it's possible to use the rubber engine mounts (the ones with a thread both sides) in a verticle configuration? Rather than
in the more normal horizontal.
Thanks in advance.
Who the f**K tightened this up!

Mine are at 45 degrees and i have seen them used verticle a few times so should be fine 
How long can i resist the temptation to drop a V8 in?

I have mine verticllay mounted but it does give more vibration through chassis. Ok for track but may be rather tiring for road use.

Rubber mounts stressed in shear or tension typically fail much more quickly. This kind of mount is usually used at an angle in the original
application to provide resistance to sideways movement, as well as keeping the rubber mostly under compression. Unless you are suspending something
much lighter than an engine you should have a look at the engine mounting systems used on modern cars where the engine is often "hung"
rather than sat on the mounts.
You also need to consider what will happen if one does fail, with an angled or horizontal mounting the engine is prevented from falling onto the
ground!

I've never had vertical engine mounts but did have one supporting my silencer. After a couple sheared off, I moved to horizontal.
Originally I had horizontal engine mounts but this provided little resistance to engine movement under heavy cornering so I got some new mounts made
at 45 degrees and it's now rock solid. Torque Technique in Salisbury made them (he's also a dab hand with exhausts as well but not cheap).
Seeing as I'm not far away, you could always come and see mine if you need inspiration.
Cheers Alex
