Really looking forward to the low NVH mount. I will definitely be in for a set. I will be transitioning directly from AWR/Good-Win/Supermiata 70A mounts so will be able to give a back to back subjective comparison. My 70A mounts are great, but the NVH is pretty damn significant. Super excited to get a set, test the low NVH, and see the effect of lowering the engine.

Any info on how the Low NVH one's differ? Is it just a lower durometer bushing? More bushing material?

I see V8Roadsters are doing something similar too: https://www.instagram.com/p/BHiXU_aD...by=v8roadsters (in terms of a lower NVH version of poly mounts, don't think theirs is intended to drop the engine)

Blackbird

The low NVH mounts are using a bigger bushing altogether, more wall thickness in it to absorb energy.
Initially they will be released in 70A bushing durometer and we're working on a lower durometer bushing as well, I'll post some pics later this morning

Blackbird

...Aaand here they are -



Compro between standard comp bushing vs. low NVH bushing, there's a significant difference in wall thickness -



We'll have pricing and start taking orders Monday

astral

Beautiful looking piece. Is the low NVH bushing made of poly still, or is it a rubber bushing? I'm definitely in for one of the low NVH bushings. My body and car is ready to have an unchattering dash.

Blackbird

Thanks!
Left you a poscat because of the Martini Lancias... definitely a good enough reason!

astral

Thanks! I'm a hardcore gruppe B fan if you can't tell. What a time it was.

I actually have a question about lowering the engine. Is this likely to affect clearances on things like turbo downpipes? I actually had to add a garagestar engine shim to raise my engine a bit back when I had a racing beat header. The header would rub the subframe without it.

If the engine is lowered, downpipes may be lowered closer to the subframe, no?

I do think this could be a real issue. I know at least with my setups the down pipe will probably hit.

Blackbird

Yes, this could be an issue with some setups, and for that reason we'll be offering the low NVH mounts in standard mounting height as well.
This should give everyone a solution that will fit their particular part combo.

Blackbird

Was hoping to get final pricing done today as well as start taking orders, but still holding off for pricing from one of the suppliers.
I'll update as soon as I have it done and ready to go

astral

Any rough estimate as to when the standard (non-drop) low NVH mounts will be ready to ship? Are we talking days, weeks, months? Thanks. I am about to drop an engine in and wondering if I should just wait to drop it in.

Blackbird

I'd estimate it being right around 2-3 weeks from the moment orders are placed until mounts get shipped.

astral

Any updates on the mounts Blackbird?

Alternative

Drilling a few holes in the bushings will help NVH, understanding you will also reduce strength.

for those who find them intolerable.

Picture a revolver cylinder.

Blackbird

Yes, I'm definitely overdue on updating you guys about our new mounts
I would've loved to have the on the market already and have money coming in, but I don't believe in releasing untested products or ones that I don't feel like we built the very best item we could (given a price target of course)...
These are the reasons that held me back from taking orders over the last couple of weeks, and I've had plenty of guys calling asking about the mounts with their CC handy...

So, I put a couple of extra tweaks in the design and while we're at it finalized our VVT engine mounts as well, so both the 94-00 and 01-05 mounts are going to be available right off the get go
VVT mounts (hardware not shown) -



But now onto the part that everyone wants to know, testing the low NVH mounts.

It was a huge success
We tested the competition mounts and the Low NVH mounts back to back.
To remove any chance of bias or placebo effect on myself I had another driver coming in today to make sure my feelings were confirmed, and the verdict is that the low NVH mounts are doing EXACTLY what I was hoping for them to do.
We started with the standard comp mounts, had our customer (local racer, last year's Roadster cup champ) take his car off to a route that allows testing in all conditions - city driving with stop and go traffic to a local mountain road which gives you a good amount of room to run hard, and return to the shop taking the freeway so he can evaluate cruising.
He came back saying the car shifts like butter and all of the crunchiness he had in his 6 speed is gone, he was very surprised by how well the shifting part worked and said it did not matter how high and hard he ran the car, it shifted perfectly.
He also noted that the car was vibrating and booming quite a bit on city driving and some while cruising on the freeway, noting that low revs decel was particularly harsh (like rolling to a light).

One thing that left him a bit puzzled was that he thought the car turned better, as if the reaction from the steering was quicker... I left out the part that these were the drop mounts we installed on his car, looking to see if he noticed any difference, and he sure did.
So far so good, everything worked exactly as expected.

Off came the competition mounts and on went the low NVH mounts.
We sent him off to tackle the route again to evaluate the differences, as his car leaves I walk back into the office but something like 15-20 I hear the car coming back down the street and got a little nervous that we might have missed tightening some bolt or something..
Nope.
He was so impressed with how HUGE of a difference it had in NVH level that he made a U turn and came right back to tell me how much better this setup is, SUCCESS!
Sent him back out for a test drive and he came back asking if he could keep the set on the car...
So yeah, my one setup that I had of the prototype low NVH mounts is now gone, haha!

I asked him to rate the low NVH mounts based on the Mazdacomp rubber mounts he had on the car before being 0 and the Blackbird Fabworx competition mounts being 10, he rated them at 5-6 for shifting quality and 2 for NVH.
I'm definitely calling this missing accomplished.

And with all that said, we are ready to take orders!

The 94-00 set is selling for $255 plus shipping.
The 01-05 set is selling for $280 plus shipping.
Local pick up is available!

Mounts for 90-93 cars coming soon.

Please shoot me an email to place your order - sales@blackbirdfabworx.com
Thanks!

What are the differences between the 94-00 and vvt designs? I thought all 1.8 brackets where the same. I'm tempted to run the low nvh drop mounts but have no clue if my dog pipe will be resting on the steering shaft. I'll take a gander. Might order these after all.

Blackbird

The VVT engines have an extra bolt at the back.
You can physically run them with the 94-00 mounts, and I expect some will opt to do exactly that for the purpose of weight reduction.
However, since we have them both with or without the extended flange, everyone can run the config they prefer.

If you want to include a set of mounts with your roll bar order, they will ship for free

Have these been tested with RB headers in any year of car for clearance?

Blackbird

Yes, I have one on my own car (99).
No interference of any kind and the rear flange is sitting flush with the frame rails -

astral

Can you comment on the fitment of a flyin' miata downpipe? Is this going to drop the exhaust itself lower? I'll be in for a set immediately if it doesn't cause issues with my downpipe.
