Powerflex Dogbone bushing was delivered today, so I set about installing it.
Removal of the old mount was stupid easy.
Looked to have been replaced at some point not long before I got it. Looked fresh but still felt very soft and mushy.
Cut out the old bush with a hacksaw, only difficulty was the hacksaw getting stuck in the rubber. Needed to sand off the white oxidised crap in the console. Got 90% of it off and the console felt smooth so I was happy to leave it there.
Install of the bush itself was a bit fiddly, The photo on the listing I bought it from showed it as a 2 piece design. The bush I got was 1 piece. That said it was not hard to do with a vice, just took a little more planning. I didnt get any instructions with it and accidentally put the bush in wrong (I think). The relief in the bush looks to be for helping with installing it into the car. I had to take it out and install it 180°, relief facing the back of the car.
I removed the black part of the mount when reinstalling to make it a little easier. Took a fair amount of effort to get it back in, seems that since the new bush is thicker it has a hard time going in.
I did all this over the pit, didnt need to take the wheels off or even lift the car surprisingly. Actually made it easier as I could sit on the step and work away. It was a little sketchy at first as this pit is made for lorries and the like, not small hatchbacks. Had a half a tyre over the edge on either side .
I decided to go for Powerflex's PFF85-620R, their softest dogbone bush. Its a 65 shore bush and felt surprisingly squidgy out of the box, I wonder if a stiffer bush would be harder to install as it wouldnt contort as easy to fit through the bush?
Having done a bit of driving on it I can say that it has improved the car nicely. Its a lot easier to change gears, much more predictable. I have not noticed any increased vibration at all. The only time it is noticeable is on starting the car and turning it off. Turning it off feels similar to turning off my mk1, as I removed the ASV from it. Its a difference, but not a big one in that department. I suppose it will soften up in the next few days, hopefully not much. It feels good now, feels like what it should have come like from the factory. Feels much more consistent even under some hard gear changes. Definately worth while for the cost and time to do. The great thing about having 2 fabias is that if I want a stiffer bush in this I should be able to put a stiffer bush in the mk1s mount and swap them over, both look identical so I imagine they are the same part.
Overall quite happy with this mod, I like the feedback when starting and turning off the engine and its not noticeable at all under normal driving. Its the sort of mod that I love to do, much like the RARB.
Next thing up is a remap, all goes well It should be mapped by the end of the month.
The place i'm going with claims 145 hp and 310 nm of torque. While I think thats a little optimistic it should make a big difference.
I'll hold off on the intercooler for a short while, since the weather has cooled off again its not gotten very hot since. Looking at doing a wellycooler job to it. I have my eye on an alloy intercooler that should do the job.
