Interested in hearing how much more noise these make. Do the 3.63's make more noise also?

3.63 is an OEM gearset

OEM R&P (including 3.63) are essentially silent. Having a slightly lower helix angle, I'd imagine the MF 3.3 is very quiet but not entirely silent. My guess if you are making enough power to require 3.3's, you have other stuff making more noise. In any case, if a tiny bit of NVH is not your thing, you probably shouldn't be building a turbo street Miata.

By the time you get someone to answer this, it won't matter, because they'll all be gone. :party:

^ Hence why I ordered them; SOMEONE will want them down the line if you don't like the noise.

I lined my trunk floor with peel-n-seal and frost king foil backed foam and it eliminated a large amount of exhaust noise from back there. I imagine this will help quiet things somewhat but TBH if the top is down you'll probably struggle to hear it.

Just ordered mine. Per the notes on the web site, are these gears shot-peened and cryo'd, or is that just boilerplate specs?

I think they have plenty and are just suckering guys like me who wanted to wait a bit into giving them money now.

You guys are worse then the ammo scare when there was no .22 left cause everyone went and bought it all at once lol! When these are gone is it not possible to get more made with enough money up front from people willing to buy them? Are they made of unobtanium? (Serious question...Im new to the Miata game)

Miata is not game. Miata serious business.

15 set were available, moq is 30 sets

yeah, decent possibility when these are gone, they are gone

When I saw these on the website, I didn't think about it as I figured someone was stocking them? I see urgency now, so just ordered a set. As to axles, I have had discussions with DriveShaftShop, and no problems. However stockers are so cheap and plentiful, and the Mazdaspeed are basically unobtainium, that it is hard to justify something custom just for a cheaper OSG alternative.

Savington you said they came in 2 day shipping? How long did it take for them to ship?

Mine shipped in 2 days. They are on their way to me now.

And I believe they are out now, if my numbers are correct. Stock does not appear to be updated live.

Yeah I just did the numbers... and counted 8 people who ordered here after it was said only 9 sets were left. (Actually by my count they should be gone also). I ordered mine. Been planning on this since last month. Was gonna get the 636. But this was around the same price and I should save some money on gas in the long run lol

The site is still showing them as available.

I don't see a supply count either, just a green check box saying that they're in stock.

Yeah, and it also lets you add 20 to your cart. When we heard from mike that there were at most 15 left. gl

Mine is on it's way. I was wondering where people were getting the # they had too. They list front and rear limited slips for my 04 VW R32 too and one of those is on sale. That and you guys are probably going to talk them into a 6 speed gear set from the sounds of it. Sort of wish I'd never started browsing that site. This is adding up quickly!!!

Still got a NIB 3.63 I'll probably never use now too...........

Per Patrick@Mfactory they are all gone and I orderd the last one :)

From there

lol y'all acting like it would be a bad thing if they kept making them. who cares? those that want/need a 3.3 are getting a killer part that was deemed a myth just a few months to a year ago, this is really cool. And I'd be surprised if MF didn't see the demand these have and started pursuing making more, as well as more trans stuff for Miata's. It's probably the only weak link left on turbo'd miatas.

Heck, I bet already most of the other companies have offered to sell their stuff and be their distributor, or do another run of these in the future :)
(that's the only reason this thread hasn't been flagged repeatedly for "non vendor" by now :giggle: )

...But seriously MF: y'all gonna have to become a vendor if this keeps going.

While there is demand, I don't think it is high enough for MFMike to make more. 30 people to get another batch made is a bit large, especially if you are trying to get them all to coordinate and pay up front. Not impossible, but highly unlikely. So while I could see them selling 30 more, it would probably take several years and I am doubtful they want to sit on them for that long.

There is also the issue that speedo will be off, I don't think Mazda ever made a 3.3 speedo sensor. So that is something else that will have to be dealt with.

My soul hurts to see these go, i was going to purchase them tomorrow :( It would be great and a good thing if they kept making them, I missed out and so did many others did i am sure.

Lets hope MFMike comes in and says production will continue, otherwise i see a 3.63 in my future

Maybe you're right. Bill only had 24 people on his GB after much promoting and advertising.
Oh well, who cares, doesn't matter now :dealwithit:

The only reason these sold is because they may not be available anymore. Its like a Catch 22. If you stock them everybody waits and nobody buys them and they sit on them. I see it from both point of views. But everybody talks about spending money. But most don't ever do it.

I don't think you've been around long enough to make an incorrect observation like that. Maybe on ricer sites like CR that's how it works, but here the people that race are usually the people that have money, and spend more of it on a monthly basis than some of the stance retards spend in a year.

Sure the majority of the community is poor/broke/cheap, but let's not ASSume

I don't believe what he said either. There is a large population of cars and the need is evidenced by how quickly these sold once discovered. A lot of us wouldn't be as likely to contribute money up front to a pie-in-the-sky, hope we can get a product that doesn't exist group buy as we would make a direct purchase from a supplying vendor for a real item in stock. I don't trust GB's for items that don't exist yet.

Regarding the speedo gear issue, I had a custom gauge face made by Revlimiter to match the change from 4.10 gears to 3.63 gears. It was not expensive. He could easily scale it for 3.3 gears in the same way. Problem solved.

I use one of these on one of my motorcycles to correct the speedo for gearing changes and to just get rid of the OEM "error" they always include. You can set them to anything. There are other similar things available. Guessing they would probably work for the non-mechanical Miata. Can you not adjust it through MS on the newer cars? Sorry that's probably a dumb question but I was thinking you could. I've not installed my MS3 yet.

You can use them on NBs. Not on NAs.

NB speedo is driven directly from an electric sender on the trans. So you have to do custom wiring to make it work through the megasquirt.

You could probably make that work for the NB without much issue, NA's are purely mechanical so it does not work. FM sells an expensive box that will convert from electric to mechanical that they use in LS swaps, but I am pretty sure it is super expensive.

You might be right. We will see how it goes I guess.

Think of it this way.

Would you rather buy vaporware that sounds awesome in theory or would you rather buy a reproducible part that has the blessing of folks that run this shit hard enough to form a solid opinion. Oh, the experience of the latter in this 'niche' industry doesn't hurt all that much either.

Look at how fast the 3.6's on the classifieds sell? It's gone within a few days at the most. Folks are much more willing to put down a deposit on something that is real and exists instead of something that sounds good with no proof of concept and a random person behind the wheel of the project.

^ I completely failed to take that into account, I'll need to get some for 4.1 to 3.3. Thanks for bringing it up.

I mean we could go back and forth debating this all day. Maybe my opinion is right and maybe its wrong. In the end opinions dont matter though. I hope that these do get produced as more part choices is never a bad thing.

Maybe it's just me being an NA guy, but you all are sitting here salivating over 3.3:1 final drives, and I'm wondering if there's any off the shelf 5+:1 ring and pinions for less than Prather's cost for his run of 5.12:1s

MM-MAZ04052028 - Maruha Motors ring & pinion gears - MiataRoadster - High-performance service...and parts for Roadsters

Not sure how that compares price wise.

That tends to happen when you're actually making power :D

You can get aftermarket Kia Sportage 5.12 gears for even cheaper I think.

5:12 with 6 speed might make nice Miata rock climber. Should redline at about 25 in 1st.....

I would have bought one of these, had I not decided to do productive things yesterday insteading of stalking mt.net, and therefore missed out on the frenzy.

I've got one for sale. $2000?

found your mistake

I ordered one yesterday morning as well.

--Ian

For all the talk about how these would easily sell if they were made, 3.308s have been a rumor for ~15 years and nobody has put up the money to actually produce them. $600 a pop, 30 point margin, so that's $~13k landed in the US for 30 sets. Sell them all at $600/ea, post a few forum threads, spend a few hundred on vendor fees for a couple of months, and it's a ~$4k profit easy. If it was such a sure thing, someone would have done it by now. Instead we're scrambling to buy the leftovers from the one aborted project that almost got them mass-produced in the 15-20 years there's been demand for them.

They were unicorn gears then, they'll be unicorn gears forever, IMO. Anyone who says otherwise should put their money where their mouth is :)

OK, since they have sold out, can't we cut all the conjecture, and get back to a trans solution? ��

:bowrofl: funny because 100% true

I think this is probably the best explanation. They were built and sold.


I think this has more influence as well. I think we will see another run. But since I have a set on the way I am hoping Savington has it right. Having something rare for my miata is the only thing that helps me sleep at night.

I would just like to add that whoever gave me a negative cat I hope your ECU gets aids.

[QUOTE=Johnny wangwang;1400583]Interested in hearing how much more noise these make. Do the 3.63's make more noise also?[/QUOTE


while this doesn't identify the manufacturer or details, I am betting that this is the gear set PuddyMod Ben installed and reviewed here...

i still ordered; not sure if I got in while stock still existed.

I'm sure they'd sell some of those too if they'd answer emailed questions about them. I almost bought one of their gear types "rated to 1000hp" after I broke mine, but no response on if that was a real number or what the TBR was.

[QUOTE=M2Ken;1400863]For someone who wants to confirm, you could slow motion the video and count the teeth, there is writing to identify a start/end of the count on each gear. If it's a 3.3 ratio then it's probably these gears since I don't know of anyone else who ever made them. The description (rough machining, not a flawless ground finish) matches the pics on their website and description here.

Pure speculation or direct personal experience? On this forum, we are pretty serious about quelling speculation posted as fact.

The reason you chose this forum is for the signal to noise ratio far better than the norm. Help to keep it that way by adding some veracity to your claim please.

From 0:51 to 0:54, he spins the gear slow enough to go frame-by-frame and count individual teeth. I count 43.

He never spins the pinion slow enough to count, but at 1:47, he shows a clear image of the pinion gear while stationery. You can't quite see half of it, but you can still see six teeth. If six is less than half, then the pinion must have 13 teeth.

Hope mine aren't that noisy. My gear shop is good enough to tell me if they will be, though.

[QUOTE=M2Ken;1400863]That was posted April of 2014...

I am not authorized to speak for the source. More than speculation...

I don't think you understood what he said.
To claim more than speculation you have to actually provide facts or speak for or as the source.

and MR started the project in 2013
https://www.miataturbo.net/miataroad...oup-buy-76264/

but still speculation at best, obviously

I think I understood Mr. Cervantes to identify that conjecture and bullshit has no place on this board. I have been here long enough, mostly as a lurker, to know that. Did I misinterpret that?

Nope, all set :)

Reached out to Ben. We'll see what he has to say.
