Powerflex Tuneable Engine Mounts PFF5-4650

[maicol76]

I installed Powerflex Tuneable Engine Mounts PFF5-4650 yesterday. Fitment was perfect.
This has very little more vibration than stock without 4 black polyurethane insert pins at idle. The vibration disappears during driving. Considering my mod is race seat with floor mats removal, I'm very satisfied with this.
I did't have test driving with 4 insert pins yet.
And, these are about 0.2"(5mm) higher than stock.

I'm going to test these at the track asap.

As far as I know, this has just been released. The information was limited, so I bought it on the basis of the company's reputation.

so how are you supposed to get those dowells out once you put them in? do they slide in and out pretty easy?

IMO, not easy, but not difficult. Our M3 has not enough work space to insert pins unlike E46 M3 on youtube. But, It's not difficult to put in and out with grease.

It's only been a day since I installed it, so I can't give you guys more information yet.

Neat. But the fewer moving parts a component has the stronger it tends to be.

I am iffy on long term reliability of "rebuildable" mounts from this brand and another.

any new updates?

[maicol76]

Here is new updates after 6 trackdays.

<without 4 black PU pins>
Very slight increase in vibration at idle/stop but no difference in nvh from stock.
The improvement in response and shift feeling of DCT is immediately noticeable, especially in high rpm.

<with 4 black PU pins>
Not yet. Because I was very satisfied without pins, so I didn't test it.
I'm going to test it on next trackday.

IMO, If you use this without pins, I think this kit can achieve both performance and comfort at the same time.

[roastbeef]

Ok but, stick 'em in.

[StripclubDJ]

Just put the tips in.... bro

Is there any updates to how they are with the pins installed?
Thanks

any more update after half year? hows the vibration during idle with pin?

[maicol76]

Recently I removed Powerflex's, installed BW's.
The only reason for changing is because the height of BW mount is 5mm lower than pwerflex.

NVH : powerflex with pins > powerflex without pins > BW

IMO, I don't know the difference between BW and oem.

so you are saying even powerflex without pins has more nvh than bimmerworld??
i was under the impression that many peeps found bimmerworld hard to tolerate due to the vibration at idle

Yes. I also read the impression of BW, so bought a powerflex.
After installing BW, I thought it was a OEM mount. If you are very x100 sensitive, you may notice a difference from OEM, but I can't feel any difference, even sitting in my bucket seat with race steering wheel. I don't know the reason I can't feel the difference. because my idle rpm is 750~800?
IMO, It's clear that BW is much closer to genuine than powerflex, but In terms of performance, powerflex seems to be a bit better than BW.

Looks like Vibra-Technics is still the ones to go for. Zero additional NVH compared to stock for me.

[nycplumber]

+1 VT on my last m3 and will do the same on this one as well

[AC/DC]

Personally, I like Turner Motorsport's engine mounts. They've been good thus far for me.

I have the PF engine mounts installed on my e92 M3. You can feel engine vibration a bit more at idle compared to stock but that’s it. I’d say it’s increased NVH at idle by ~15% over stock mounts (with GC camber plates). Additional NVH disappears as soon as you start driving.
