Lower engine mount - Niall - 18-10-2014
Afternoon all,
Ive currently got a yellow Powerflex bottom mount which was spot on and a nice compromise on the standard engine however since fitting the charged engine, its not really standing up to the job i assume because of the extra power. Im looking for something a bit stiffer but don't want to go silly as i don't like the whole cabin vibrating lol.
Are the diesel powerflex mounts any stiffer than the petrol ones? And if thats a no go, I've heard of some people fitting a standard mount 90 degrees to the standard position. Again, any good?
Thanks all

I thought the diesel ones were slightly softer?
RE: Lower engine mount - Dum-Dum - 18-10-2014
IIRC the diesel (red) ones are softer as are the black powerflex. Purple might be harder but they dont make those.
The standard mount at 90 degrees is still shit.
I'd go for a Baker BM set up as once they have been on the car a few thousand miles they soften up considerably.
That or replace the top and gearbox mounts with something stiffer than standard as the 3 mounts work together.

ive got the full baker set on mine, alot less movement than before, bit of vibration but they do soften up.

Make your own!

Take an old bush and burn the rubber out.
Attach the two steel pieces you are left with on a piece of plywood (don't forget to sink the middle piece into the surface),
apply release agent to the wood (generously) then pour the polyurethane.
Wait a few hours
Demold
Allow bush to harden for 24hrs
Reassemble
...
profit??

Vibratec from evilbay £30
identical to the bm but still with the vibratec branding moulded into the rubber

I would highly recommend the Vibratechnics one.
clicky
RE: Lower engine mount - powerandtorque - 22-10-2014
For what it's worth, I've never found a Group N lower mount coupled with new/decent standard gearbox and upper mounts (and fork bush) to be too bad at all from a vibration and rattles point of view - that's the setup I tend to run on all my 205's to minimise engine movement without considerable increase in NVH
Given that's on a 205, which have far shoddier interior build quality than a 306, you should be fine.
It's when you start running Group N mounts all round that it becomes pretty horrible as a road car. The first few hundred miles before they settle down is bordering on intolerable frankly, although it does become better as the miles increase (if still unpleasant)
RE: Lower engine mount - Eeyore - 22-10-2014
Just looked through Baker BMs site. Is it also worth replacing the fork bush?

RE: Lower engine mount - powerandtorque - 22-10-2014
Not if you value your fillings!
Again, I can only speak for 205's (but it's basically the same bush) but that fork bush dramatically increases NHV and, combined with Group N mounts, is frankly intolerable on a road going car. Defo track / race only that one unless you're a masochist
Personally, I'd just fit a new standard fork bush if yours is looking worse for wear.
RE: Lower engine mount - Eeyore - 22-10-2014
Okay sure. I didnt know how much harsher it was than standard. Hadnt heard of people fitting them. Cheers
RE: Lower engine mount - zx_volcane - 22-10-2014
i've got baker bm polybushed fork you can try if you want - least it doesn't take long to change out
it was horrific on my derv though
RE: Lower engine mount - miles - 22-10-2014
As above the lower engine fork takes most of the vibe's from the engine along with torque re-action, the top 2 do very little really bar support the engine,
Vibra one's I have never had a issue with which is why I always use them and in a 306 bar maybe on Idle I think they are fine
