Shore rating for engine mounts?
DIY Si - 20/7/12 at 01:05 PM
Afternoon all.
I'm looking at buying the engine mounts for my project shortly, and was wondering about Flexible Engine Mounts Marine / Boat
Anti Vibration M12 | eBay
.
I would rather buy something a little OTT that will last for a good while rather than buy cheap just for the sake of it. However, I am unsure which
rating might be best. The engine weighs roughly 120kgs, plus gearbox. So by that thinking 75kgs/mount will be plenty. But will it let the engine
wobble all over the place, or is it better to go for the harder ones and have the engine better tied into place? Or does anyone have a suggestion for
a better engine mount altogether?

It depnds what your project is. If your project is just and engine mounting frame, then the weight of the engine is all you need to consider. If
you're wanting the engine to power something, then the torque and power of the engine is more relevant than the weight of it!

I cant view ebay at work but my first thought would be that the engine mounts also have to control the reaction to the engine torque as well as the
weight.
Feel free to correct me if this is not true.

FWIW I made my own differential cushion mounts from two-part poly rubber and I used 80 shore, it was harder than a stock engine mount on a 2 litre
turbo but not hard enough to notably increase vibration in a tin-top.
Not exactly scientific but might help a bit.

Wow, £19.95 per mount + £9,95 postage = ~£50 hardly locost
What's wrong with SERIES LAND ROVER DIESEL ENGINE MOUNTING RUBBERS (FOUR) | eBay, for £18, a lot more locost and will
easily stand the forces involved.

The main thing wrong with them is that I won't be able to attach them to my chassis rails. 
Otherwise, I would indeed just buys some. But I
need a mount suitable for a flat(ish) surface for a 210bhp 8K rpm limit V6.

I don't know where mounting points are on your engine but do you have to fit the mounts to the chassis rails? I'm fitting a 4AGE in mine
and decided to make some mount brackets that are angled forward and fix to rectangular Fiesta mounts that are fitted near to where the original mounts
fit.

My engine will sit a bit further back than yours, and the mounts are more central to the block, so probably 4"-6" back from yours. I'd
rather not have them pointing that far forward for the sake of saving £30 on a car that'll cost me £6K.
Yours is looking good though, got a build thread going anywhere?

Apply that logic to the whole build and it will quickly become £10k!
I paid £5 for mine:
ANR1808 ENGINE MOUNT LAND ROVER | eBay
They're very solid (intended for big heavy Landy lumps)

With the engine mountings being so far back then you are better off mounting onto the chassis rails. That was my original plan until I looked into
finding a suitable mount then sat there with a cuppa looking at the car pondering my options.
Here is my 4AGE Midget build thread.
