I don't spell well

Default broke tranmission with mFactory gears

What they were working with:
I've had the gear set for about 2 months and only have 1900 miles on the gears.
They were mated with a gruppe-s lightweight flywheel and a ACT 6-puck sprung clutch running redline oil.
Stock shifter on DS1's recommendation.

What happened:
Took 6 runs at the track and went home. On the way home, we hit some traffic, so I stopped. Shifted to first, then second and noticed a sound like metal grinding from underneath the car. Shifted to third, nothing. Shifted to first, nothing. Shifted back to 2nd and now it got even louder. It almost sounds like you put a baseball card in a bike wheel, but with a more metallic ring to it. So I pulled over and looked for loose parts. Nothing, everything's tip top, except 2nd gear. At this point I realized I'm f-ed.

How hard did I beat them?

Well, I never missed a shift and never ground a gear. I always made sure the gear was engaged before letting the clutch go. So I was as careful as can be with them.

How much power?

It depends on the dyno. If I use airboy's dyno spreadsheet (which is pretty much spot on with xxtuning's dyna pack dyno) it's 319whp 301wtq. If you go by precision tuning's dyno jet it's 328 whp and 358 wtq, but I've been told that dyno reads high.



Any constructive info will be appreciated.

Thanks
-Tom


EDIT: I'll update the thread we I get more info, but I shouldn't be making claims until we figure out what happened. For now, 2nd seems to be toast but let's reserve judgement until we have a cause of failure.

....racing parts = not insured = sucks for you....
Call whoever built the trans for you and maybe they can do SOMETHING to help you out but they're not obligated to do so, just so you know.

Should have got PPG gears, sorry bro. I made the same mistake getting the RA gears and and 04 wrx trans that is supposed to be stronger. Guess what, they both broke with the same power you had. Lots of money wasted and downtime. Do it right this time. 6speed swap or PPGs. Call it a day.

Damm man. Sorry to hear about that. I think its kind of funny though how everyone was smack talking the RA gearset and proclaiming how incredible the MFactory gears were. My RA-gears held up to 357/381 up until my motor gave out.

I can't wait for the new Helix gearset. Its going to make RA's and MFactory gears obsolete.

Wow, I'm surprised they broke that quickly at those power levels... Maybe they won't live up to the hype.

Sorry about your luck.

Bad Noodle: See what I mean about my "90% of the internet population" and the "grapevine" comment

iRace559: Why would our gears be obsolete? The purpose of our gears is NOT to handle more power. If that was our purpose, we would have made them longer ratios and from different materials. Do some research into "close ratio gears" and what our gears were actually designed for. It is not necessary to have to increase the power of your vehicle to use our gears.

Everyone Else: We are looking into the situation and will be working with Bad Noodle to determine what exactly went wrong. I have said this before, and I will say this again though, Everything breaks for a reason. We just need to be given the opportunity to look into the problem, preferably without the inevitable smart-ass comments (not targeting anyone in particular). We stand by our products 100%

... care to share with the rest of us?

Edit: Nevermind, found your post in the Mfactory thread. I understand what you are saying and your concerns. Negative information spreads like wild fire on the internet. Thats why everyone thinks RA's are worthless and that the stock box can't hold it's own weight.

What I meant was, when someone posts anything with the slightest hint of negativity, 90% of forum users would just look at that negativity and not the full picture, then spread the negativity like wildfire down the internet grapevine.

I can see it now:

"MFactory are just hype and no better than RA's"
"MFactory are crap, they break with only 360lbft"
"etc etc etc"

Just watch this space, and you will know what I mean

People don't realize just WHAT our gears were designed for. We didn't design them to handle power, that wasn't our priority. We designed these as a close ratio gear set for Auto-X/Circuit/Street use. There are limitations, but unfortunately, power is so engrained into the minds of 99% of the general population that that's all they think about.

Sure... I'm pretty about the whole thing so I made this thread and copied it into the mFactory Gears thread. I wasn't trying to be a jerk, I'm just upset about the the while thing and needed to vent and really wanted to talk to someone like mFactory or DS1 about it. I figured that if I post it in two places I'd have better luck getting a response.

I'm not trying to spread rumors or anything, I'm just really want to work with the vendors to figure this problem out.

It's just one of those things that you realize what you've done (in my case spent a good chunk of our savings and promised the wife that if I get these then we'd have nothing to worry about) and it's really sinking in and you want to figure out a way to fix it asap without getting into deeper trouble. I personally just feel bad for my wife.

So again, I do apologize if I'm being rude or unpleasant, I'm just taking it kinda hard

If you pm'd us, you would have gotten a response immediately (as I always reply to pm's within a few hours at most).

As I said, I understand your frustration, but before we can "fix" things, we need to determine what happened first. There are a multitude of things that could have went wrong, a lot of them nothing to even do with the gears themselves.

Rest assured though, I stand by my comment and pledge, which is: We stand by our products 100%

When the center diff blew out on my /02 it had that baseball card clicking sound. Turned out to be the retaining ring on the center diff. broke and unwound inside the tranny. This left my fluid very black and gooey. Have you drain the fluid to have a look?

Sometimes a little perspective helps or makes you feel better about a problem.
A few years ago I built a 'drag race car'; I took a 12 second 72 Nova and worked all winter in my garage by my self and turned it into a 9 second car.I put top quality parts and careful attention to detail, but things can just go wrong. As soon as the track opened up in the spring I took my son and several friends for the first test passes. I was warming the car up on the return road and got on it a little and blew the brand new 'TCI' race tranny[it lasted about 1/4 mile]. Took the car home and sent it back to the factory with my 'sob story'. Ten days latter they sent me a new tranny[first pass was 10:68]
I believe 'MF factory and DS1 will work with you ; just give them a chance.I am saving money now for 1-5 MF factory gears so I will be watching this closely. GOOD LUCK!

Oh, I have no doubt they'll work with me. So far they''ve been great, both of their support is top notch.

I'm waiting to call DS1 since they open at 12 and they're 2 hours behind me time wise. So I figure I have time to go home and look through everything, drain the oil, so I can give them the most details when we talk about it.

Indeed, sometimes things just go wrong... You run that risk any time you modify a car for higher power output, and even factory cars fail under normal conditions, that's why there is such a thing as a warranty. Could be a fluke manufacturing defect, could be tolerances stacked up in the case/bearings/etc... Not like bearing issues have never ever reared their head in a 5mt before (I speak from experience). Could have been a lot of things. Could have just been bad luck.

I'd give Mfactory and DS1 a chance to straighten things out before people start saying Mfactory's gears are not up to par. I'm interested to see what the cause was once DS1 does some mechanical detective work on that transmission.

agreed 100%

In fact, I never said they're not up to par and i do believe that this is just a fluke. As I've said, DS1 and mFactory are great vendors and if anything, this thread should reflect that. So far they've both been very helpful and I can't stress enough how much I appreciate the support I've gotten from both vendors.

And again, I apologize if it seems like I'm "calling them out" on the forums, I'm really not and nor do I intend to. I have the utmost respect for both companies. I was looking for info as to what i could check, maybe it's not the gears after all, could be something else. As mFactory said, could be a number of things that could be wrong besides the gears, I was hoping that someone would say, "dude, check this first" or "it could be this"

To me, it sounds like second broke from the countless threads I've read about the stock boxes breaking. So yeah, I guess I did jump the gun on making the claim that it's broken, but I've never heard of anything else causing these symptoms and was hoping someone could bring something to the table.

Cool, I'll be in touch shortly. Just waiting for a ride home, then I wanna get the car in the air, check the shifter linkage to make sure there isn't anything wrong there, then drain the oil and see what I find.
