Engine Mount -- Is It Done?

[Dog Dad Wagon]

This video has been shared previously and illustrates why you want to connect the upper and lower mounts. I've seen the APR dogbone bend at the lower mounting attaching point when only lower inserts are used. The following link has a lot of good information regarding the inserts and why you want something that fills the voids in the upper and lower mounts. https://store.034motorsport.com/034...n-mk75-golf-golf-r-gti-jetta-7-speed-dsg.html.

Based on the recommendation of one of my friends I went ahead and modified my powerflex hybrid mount to accept the 034 upper insert. And I should also note that the ECS dogbone is not a direct fit for the powerflex hybrid puck (had to machine down the aluminum cup thing that comes with the insert so it would fit in the dogbone).

I did the APR Lower Steel Insert + APR Pendulum bar and 034 Upper insert with stock uppers and it made a 5-10% increase in NVH, and it’s really zero N or H, only Vibrations at idle speeds in 1st and 2nd.

I am looking forward to getting the BFI Stage 1’s. Had them on my last car along with APR Pendulum bar and power flex insert. The NVH from the mounts was nonexistent Besides, like others say, a better exhaust note.

Main reason I’m interested in the cpe is it’s not poly, and it’s a stiff 70A durometer that’s the same or close to the Powerflex. Hoping it’s a Superpro fill-in, if they ever make them again. Also lifetime warranty; they may refund if it’s not what they claim. Willing to guinea pig for posterity.

What’s the issue with a poly bushings for mounts?

You’re a good man. Lots of people seem pretty excited about these, I hope GTI Jake’s predictions don’t come true. Mostly because it would be just “another one bites the dust” with the aftermarket mounts on MK7’s. Why oh why won’t superpro bring them back... I feel like they’d make more than they did before, with how much hype has built since they’re not available anymore

Nothing that I know of. SuperPro mounts are poly and are widely regarded as the best. Unfortunately they quit making them. Not because they're poly but lack of demand because of the high price. I have them and so do plenty of other guys in the forum.

I personally run the full set of green stage 2, but there’s also black stage 1 that result in a little less NVH.

NVH tolerance is subjective so just be honest with yourself as to what you’re ok with. I’ve shot several hours of my YouTube content while driving my car so the NVH (noise mostly) can’t be that bad, but again, subjective




Dang I wouldn’t expect that from them, but I guess issues can happen and customer service people have bad days too.

Good call on the six lines for grade 8, I must have been thinking of some ultra rare 8 point bolts

Wait... I have a stage 1 BFI motor mount and it's green, not black.

I was running the upper and lower Inset and actually switched to a firm poly one and was pleasantly surprised how much better the poly type is for performance! Say If 034s take out 40% of the slop/voids Vs stock the poly is on the 85-90% range.

How about NVH with the poly insert?

Much worse, lol. But I did select the spulen “extreme” version

when the cars at 650-750rpms it’s excessive, above 800rpms it’s fine... unfortunately with the 2019 ecu I can’t seem to get the obd11 to raise the idle rpm, tried many ways.

I don't know about whatever brand he used but the SuperPro poly mounts added no vibration.

It’s not typical polyurethane.

An important note to think about is SuperPro’s products line is Known for polyurethane, yet when it came to motor mounts they did NOT elect to use polyurethane... they used a product they created called polyelast that’s like a synthetic rubber because they themselves didn’t feel Polyurethane was not good for NVH mitigation on something like a engine mount.

also the fact that they WERE NOT polyurethane was why they are widely regarded as the best.

Is Polyelast propriety to SuperPro? I've never heard that term used for polyurethane elsewhere.

It’s not their regular polyurethane, the material your mounts are made of are not the same as all the other blue bushing material you see from them.

Why doesn't anyone else use Polyelast? Is it proprietary to SuperPro?

 

[IanCH]

Yes all of superpro's bushing materials are proprietary to them, it's one of the reasons they are better than most other companies in the segment

Green is stage 2.

Stage 1 used to be yellow, but a few years ago they switched to black.

They sell just the poly so you can convert 1-2 or 2-1
