I've been reading on the Swedespeed forum about the benefits of the Torque Mount Insert provided by Powerflex. However they all seem to own petrol engines. Has anyone with a diesel tried the mod? Here's the thread. http://forums.swedespeed.com/showthread.php?187255-Powerflex-torque-mount-insert-BEST-upgrade-so-far Here's a picture of the insert in place. Thanks Guys
don;t know about that but like the username How about an introduce yourself thread with some pics of the D5...:welcome:
Come on guys, it only needed one warning, remember the OP is trying to seek information and opinions here. Mr Tyler Durden (great name btw) is there a reason you are considering moving away from Volvo OE bushes? (Handling / Feel / Because the old ones need replacing and these are yellow?) Cheers :)
As OP is from Shrewsbury, it might be a good idea to come along to our next volvo meet at the Smoke Stop in Ford, that way you can have a chat and maby try out some cars. keep an eye out on the meetings section :), and for what it's worth, I think polybushing your diesel will rattle your teeth out :)
[QUOTE=claymore;773081]I think polybushing your diesel will rattle your teeth out :)[/QUOTE] it did with Bonny, i fitted a Powerflex top mount & that only lasted 2 days before going back to a Volvo rubber bush (& i'm quite tolerant to noise/vibrations)
Given that the two main lower engine mounts are Vacuum controlled by the cars ECM at a certain a rpm, fitting a 'stiffer' poly bush would, without doubt, have a detrimental effect on the cabin's vibration at engine speed over 1500rpm. At 1500 + rpm, the two lower main Vacuum controlled bushes become 'less' stiff as there is less vibration. The top engine mount is required to remain pliable otherwise you will suffer excess vibration and cabin noise. So, to conclude, it's ok to fit poly bushes of varying stiffness to a petrol car depending on it's use, but very careful consideration needs to be adhered to on Diesel's to maintain a good equilibrium between comfort/performance. Therefore, replacing the top mount with poly IMH is a very bad idea on a diesel.
I've changed lower mount and upper big and small and the strut bar and subframe mounts. Mine vibes a bit but around tick over but it's gone at 1000. I quite like it makes the car tingle and feel alive and I get a nice noise from the exhaust at 1,500 rpm then again when booting it.
As I said (the first time?), the Polybush on a Diesel can cause vibration but the benefits sometimes outweigh the niggles. A softer powerflex bushing is typically recommended on a Diesel.
[QUOTE=JamesT5;773148]As I said (the first time?), the Polybush on a Diesel can cause vibration but the benefits sometimes outweigh the niggles. A softer powerflex bushing is typically recommended on a Diesel.[/QUOTE] Can you please explain the benefits for us :)
[QUOTE=claymore;773150]Can you please explain the benefits for us :)[/QUOTE] Yes certainly. The power delivery seems smoother, the throttle response seems more 'instant' and the car feels generally more stable around the bends and when accelerating. It made a massive difference to the feel of the T5.
[QUOTE=JamesT5;773156]Yes certainly. The power delivery seems smoother, the throttle response seems more 'instant' and the car feels generally more stable around the bends and when accelerating.

As well as avoiding polybushing that top mount on your D5, I would also avoid buying a cheap replacement mount from Ebay, as mine lasted less than a year. Currently, the car sounds utterly dreadful when pulling away or reversing. Sounds as though the engine is falling out!
He's still at it and I'm thoroughly pi$$ed of that my completely valid point was removed last night, does anyone on here have experience of the torque bushing pictured at the beginning of this thread ????? and fitted it to a diesel Volvo ????, or are we going to listen to someones limited experience of normal polybushes in suspension arms and engine steadies and as Chris has said new rubber bushes would offer massive improvements over worn items, we need back to back proven informative testing, not someone's biased and unsubstantiated best guess
I haven't tried it myself no, but I did read up on the polybush last year before i bought that cheap rubbish mount off Ebay, and the general opinion was not to use the pollys in the diesels as they give off too much vibration in the cabin. However, this thread has given me an idea. I will try taking up the gap in the mount with some tie wraps, and see if it helps with the horrendous vibrations that I am getting ;)

You might be able to fit the performance ford ones st/rs and alike ;), I know on the classic x40's you can fit Mitsubishi evo bushes and components, even brakes and FTO brakes will fit.

It was more of a suggestion as it must look terrible to outsiders and new member, also it might stymie the decline of the forum in recent years by attracting new members.

It looks like "We don't like that kid in our class, he should be expelled". Did you ask those members who you listed, which I know many have their own mind and will if you could mention them? I won't pretend I like everyone on this forum, for different reasons which probably has greater basis I don't like James but people behave within the rules they can stay, those that don't can go. Sometimes I go back and question my previous decisions and based on that post you made I think I'm regretting one of those past decisions.
Oh well then just carry on as is I'm sure the forum will be inundated with new member requests.
Oh actually the op seems to have disappeared how funny.

[QUOTE=MoleT-5R;773436]still interested in how poly-bushing can increase throttle response ???[/QUOTE] Can't understand how a car can feel more stable with poly bushing the top mount, the engine doesn't flop around that much without it.
[QUOTE=stribo;773439]Can't understand how a car can feel more stable with poly bushing the top mount, the engine doesn't flop around that much without it.[/QUOTE] My only polybush experience is my purple top engine mount, all it really does is put a bit more vibration through the bulkhead and is possibly going to last longer than the standard item, due to its solid design, if your not into the extra noise stick with the standard mounting bush, though you may find they need changing more often on a more powerful engine than standard. I am shortly going to manufacture my own lower suspension bushes and lower engine stabiliser bushes, these will increase vibrational noise a fair bit, but as they will be fitted to the olive T-5R that won't matter and if they are quiet enough, I will make some more for the Gul......:)
When I bought the C70, the original top bush was shot, I replaced it with a Powerflex purple bush. I found no increase in either vibration, or car stability. I can understand what you're saying about increased vibration Ade, and I'm sure there are cars that suffer more than others (remember a C70 is stiffer to start with), but I can't see any way it could increase stability, unless it's the only bush holding the engine on.

As for stability, Chris did have a completely valid point regarding new standard rubber bushes being a massive improvement over shot ones and how new ones would compare to polybushes, but that all seems to have got lost, but it is still relevant imho

[QUOTE=stribo;773482]Yes but the OP asked about the torque mount, not wishbone bushes. ;)[/QUOTE] yep your quite right there, but in 40 posts (plus the deleted ones) no body here has posted up any info on the particular torque mount, so I'm assuming no one here has ever used one, look like they may cost a bit though
When planning the Stage 1 modifications to my C30 D5, I read the same advice.
The secondary Powerflex bush is a very poor design that circumvents the mount from isolating and is guaranteed to transmit engine vibration.
So I opted for the stronger OE torque mount from the Electric Ford Focus.
However, when I came to swap this in, I discovered that the C30 D5 has a different design mount.
