Friends there is a solution. And it lies here.

The solution

 

Yes, you are hugely overthinking this when considering the application.

This isn't an OEM clutch which will be in service for 100k+ miles aiming to minimize NVH. This isn't engineered for or by a big dollar racing team with major factory backing and big race wins with big purses on the line. It's a relatively inexpensive clutch built to be a lightweight, high holding capacity, best value clutch for a low-budget platform.

 

Agreed with overthinking it. As engineers, we love to do it, but sometimes you need to step back and realize it's happening.

 

Is there a reason people are so quick to down rate, happy to join in if that is how we roll here but it seems pretty bonkers, honest feedback... this place seems like a bunch of really good c#nts that for some reason feel compelled to strut around like they got lost in Westworld! What is it with that?? It is pretty damn funny but not fast...

Anyway shame on any engineers here that don't back me up on this. Harmonics are one of the next big moves in the budget tuning industry and this will happen with the collision of price and size of sensors and laser equipment. It will mean we will be able to get more power from lighter and cheaper kit with out blowing it up. I would say we are only a few years out from a phone app and sensor kit that will let you send the results of a torsional vibration analysis to Ivan and have your crank / cam, oil pump, you name it dampener and clutch springs come back to you perfectly tuned for your engine that you built. Get up the curve guys or get overtaken, it is as simple as that.

So should Emillio build a clever wide band dampening system for his clutch packs? The more I look into it the more I say hell yes. I would buy them and in fact I would even help him design it.

Guys can we please make this place more about rewarding initiative and pushing the envelope rather than poring cowboy communism cold water on it.

 

If you want to discuss harmonics development in Miata clutches, please make a new thread. This thread is about the current twin disc product offering. Nobody is against innovation. But you're expecting OEM-level precision engineering on a low volume specialty product.

The twin disc clutch currently offered meets the needs of those who purchase it. It is the lightest, highest capacity, still-affordable clutch you can buy for a Miata. If it does not meet your needs, that's completely fine - feel free to start a new thread and engineer one that does.

 

For one, shame on you for using dampener, we aren't getting clutches wet. And two, I'm sure E would be more than happy to discuss and develop one if you were willing to front all of the money for R&D as well as whatever MOQ is required. But the fact of the matter is, miata owners are a bunch of cheap ***** and so developing an entirely new clutch set up for one person is not a great business model. As Ed said, nobody is against innovation, but if it's not profitable, it's not gonna happen. And since products in the miata market are so price-sensitive, there's not much room for that type of optimization.

Unsprung clutches are pretty normal in the racing world. If you really want to optimize harmonics, I would start by getting rid of the BP.

 

Props for reality check

 

Useful discussion.. for an entirely new thread. Post a link here.

Meanwhile, torque is what kills the 5 and 6 spds of the 90-05 Miatas. Much forensic analysis by guys that know how to build and modify race transmissions. Known entity that. not conjecture. Perhaps new to you though. So the group response was to indicate while researching harmonics itself isn't necessarily wasted effort, it is not the low hanging fruit in getting your 90-05 OEM box to survive track use.

 

Emillio you have created the best clutch flywheel package for the Miata there is at the moment exactly as it is. At a very fair price.

I have done the due dill pulled in some advice from some experts in this field, good people I might add, rolled up a feature request to help protect our rapidly dwindling supply of cheep spares that I hope will see light in a future update, offered up a compelling argument for it, put my money on the table and offered to help for free.

I very much doubt harmonics is not the low hanging fruit in getting your 90-05 OEM box to survive track use.The Mazda B engines have a lot of shake, especially the 1.8s due the conrod to stroke ratio, this results in high 2nd order vibrations. I think it is precisely the low hanging fruit here but it is just a funny color and no one wants to eat it... yet.
If you don't want to discuss a feature request for your product in its own thread, I understand. Reach out to me directly if you want to have a play with this.

'Thank you' to the folks with the courage to say something sensible, and 'get a room' to the sportsters who are just adding to entropy with their hood exit trolling.

At least we finally managed to have a grown ups discussion here.

 

DID SOMEONE SAY HOOD EXIT!!! let's all sign up for one!

 

ZING.
