R32 Standard Engine Mounts- How Much Power/torque Can They Handle

[akaaa7]

Hey guys/girls, as title states what sort of numbers are people running with stock mounts using a 30 bottom end? Trying to decide if I should just go solid. If a mount breaks while under load with big hp can some serious damage happen? I've heard solids mounts can set your knock sensors off falsly, anyone have experience?

Ive had polyurethane engine mounts in another car.

All i will say is when i started the car in the garage, the windows at the back of the house were shaking, the first drive all i remember thinking was my fillings were about to fall out and everything outside the windscreen was a blur from the vibrations.

I didnt make it 200m down the road before turning back to put the rubber mounts back in....

If your worried about mounts breaking you can mod factory mounts to interlock when on big power or build a torque strap.

Modding the the factory mounts to interlock sounds interesting, have you had experience with this? Do you know of a link to info? I'll google and see what I can find. Thanks

Currently holding 500kw with 4cylinder cortina rubber mounts

haha maybe im being too cautious steve. I had nismo mounts that are "hardened rubber" but the top of mount has come completely seperated. Only 250kw but a super responsive setup

In plain English, a bracket welded onto one side of the mounts steel bracket that reaches out and curves over to the other sides steel bracket with a few mm of space before it contacts the other side for movement.

Under normal driving the rubber cant stretch enough to make contact, under hard driving the plate will contact the other side and make a solid stop.

Sort of like a C section welded to one side and leave a few mm of gap to the other side.

On old school engines we use to fabricate something like a alternator bracket, fix one end to the chassis, the end with the large adjustment slot was positioned on a bolt on the head with a gap to move, as the engine twisted the bolt on the head could move in the slot till it reached the end and stopped, we use to call them torque straps.

It allowed engine movement but only so far.

Im not a fan of modern engine dampners, very flimsy units when pushing big power, more show than go.....

I googled some pics of interlocking mounts, seems easy enough to mod the stock ones. Cheers I reakon I'll give it a go. I still would have thought stock mounts would be good for up to at least 300kw, doing a search not too many people are complaining about them.
