THS bottom engine mount
Carrera2RS:
Well I have it fitted.......
The good news :
Crisper gear change, a noticeable improvement in engine movement
The bad news :
A little more NVH into the shell, tolerable but I would prefer without. Feels a little 'bolted in' reminds me of more sporty, less sophiostciated cars. I will probably get used to it. But ......... the vibration and shake at 1,000-1,500 rpm is god dam awful. This sounds like a non issue as who drives at those rpm ? well watch your rev counter when you pull away normally, as the cluth engages and the revs drop to you guessed it 1,000 rpm or a little over. This reminds me of pulling away is a diesel van :confused:
Drive in town and go round a very tight slow corner in traffic and the torque allows you to stay in second as you progress, guess what 1,500 rpm happens then too.
I have heard they settle down after a few hundred rpm. If not I'll buy a stock mount and have it refitted again, I can drive around the wheel hop, I cant drive around this.....
It gets worse the bottom subframe plate had to come off to fit and my geometry has moved. The handling is not what it was.......
I have checked the number of times I have had the geometry done since February. Once following fitment of PSS10, again when fitting 8x18's as not happy, then strung and corner weighted, again when fitted TT bottom arms, then tweaking twice at wheels in motion to get the car right (It WAS great, finally), then again yesterday to make sure the car is not scrubbing as I have fitted four new tyres.
Thats 7 times and I think it needs a full 4 wheel, then again if the bl***y engine mount gets swapped.
I am feeling very grumpy and wishing I had a car that handles well out of the box :fighting:

PITA mate. Like you say give it a few miles to see if it loosens up a bit. Have you looked at the ECS type inserts for the OEM mounts? They are probably a little more compliant and less susceptible to NVH. Rhats the route i will be taking when i get around to it, because you dont need to remove the subframe.
Have you looked into getting a 2nd hand hunter rig? :signLOL:
alexperkins:
Is this the 'dogbone' mount that joins onto the gearbox?
Ive got a powerflex bush in mine. Made a good difference, though I still get a bit of wheel hop when I floor it :signLOL:
rich83:
The one on the right alex... (pic. by Robin) I presume the one you changed is the middle one?
alexperkins:
Yes thats the one
EDIT. No I put the insert in the one on the right. Havent touched the one on the left or middle.
Powerflex insert ftw :wink:
