Hi, I'm thinking up a design to reinforce my top engine mount and would like to trial it on a spare one!
If anyone is scrapping a 306 soon could you please cut out the entire mount and send it to me Smile

Not when I'm using all solid mounts, I plan on getting rid of the buffers and adding my own design that will hopefully make it bulletproof

It just makes sence, if all the mounts are solid I need to make the top of the top mount solid too and illuminate any possible fwd and aft movement!

Isnt a small amount of movement better than no movement though? Should reduce shocks from hard gear changes etc and allow the chassis to flex a little without putting strain on the block.
I could be talking crap though. Dunno

I would imagine not as the engine is mounted to different areas so in theory the load is spread out, if the top mount can move at all it will just crack!

All gearboxes on the Chinook are solid mounted and so are the engines, granted they were designed that way but in principle I think the original mounts should cope with a little modification!,

Iirc touring cars are fully solid too!

The same could be said for solid beam mounts and roller bearing wishbones

touring cars were not solid mounted, they had very different mounts to standard too

Porsche using in the last years hydraulic engine mount, solid mount transfer the shock & vibration to body directly and you'll tired of it after a while.
i remember how terrible experience i had after i installed in ZX16V Group N lower engine mount (Peugeot sports UK) and it was just a hardened rubber .

The top engine mount that ic seen look solid to me, oh well it's my choice so my problem if it does crack but I can see it more likely to crack unsupported at the top

I had all group n mounts on my last car and didn't mind the vibration! It's not a daily car by any means

Anyway does anyone have a car they are scrapping?

No, the bigger problem that you'll have is that it'll crack the surrounding of the mount ( without proper reinforcement) .

I would worry more about the gearbox mount ripping of the chassis

The way I see it is no drive line shunt, ideally the gear linkage pivot should be attatched to the engine or box but that will be the next project, see what happens I guess and go from there

Group A type mounts, NOT solid, unsure which bushes they are using specifically but they are like the front wishbone bushes.

Those mounts are surely for vibration purposes as the way they are designed they can't really stop torque reaction or allowing the engine to rock? Either way I'm going to go ahead with what i have got planned and see what happens! If it cracks it cracks

The mounts that Mei has pictured are in my car. I can verify that the engine is very well held in place! I cant move it.

I think whatever you do Ollie the engine will rip the ass out of the mounts, but Devere's car pictured is the other option, though to be fair they will have only been built to handle approx 250lbft. Ollie did you need a mount still or are you sorted?

I don't have one yet but should be going to cut one out Friday as well as getting some other bits! Are you getting rid of the shell any time soon!

If the engine wasn't in and the bay hadn't been painted I would have done something similar to above! I think what I'm going to do "should" safice! The reason they crack at the bottom normally is due to worn rubber mounts which allow the engine to rock more which in turn causes the bottom metal part of the mount to rock slightly causing stress on the structure, if there is no movement this can not happen!
