I own a Championship White 2000 Jdm Integra Type Rx here in the caribbean (Antigua) and i was inquiring as to find out if anyone has ever experienced any problems with this particular final drive. I was racing over the weekend and the track was a bit unprepped with caused my car to wheelspin excessively. I get the feeling that this contributed to fact of 3 teeth on my countershaft being broken. My mechanic told me it was a cause of excessive wheelspin then sudden traction. Has anyone ever experienced a case like this with this final drive or any other?? I also forget to mention that the same thing happened to a friend of mine with a Silver 99 Integra Type R (Same 4.7 FD) Only that he blew about 4 teeth off of his shaft.

Thanks.

 

Its a stock gear what do you expect. A good FD will fix your problems. Note I said good. See the sticky in the trans forum for failed aftermarket stuff and you can weed out what is good and bad.

<---Has broken 2 stock D16 FD's.

On a road course.

With 100.94whp.

 

going with something like the m factory FD would be an upgrade in strength. i would just make sure the gear clusters look good and go from there. since you need a new ring gear you might as well by m factory over an OE replacement as the above poster hints at "good"

 

time for a m-factory 4.9 f.d and 1'st gear!

 

Hey,
Thanks for the reccomendation. Mfactory's fd from what i understand is forged. Which should be substantially stronger. 4.9 i think is more catered to circuit racing, We don't have a circuit track here in Antigua (How i wish they did) lol. But we only have a 1/4 Drag strip. What i did do recently was replace the 4th gear that came with my gearbox with a 4th gear from a b16A. That makes a tremendous difference. I've been also trapping at a higher speed with a simple change of that gear. As soon as i put back up my gearbox i should be back on the track in pursuit of beating my previous best E.T of 14.0 All Motor/Street Tires.

 

I hope you bought the Mfactory FD and not another factory unit. You know that is what i use and have had nothing but great success.

 

i've never understood why honda used the GSR 4th on that unit. the 5th makes sense but the 4th? they should have stuck with the b16 4th like the 4:40 ITR trans has.

 

If they used the shorter 4th, there would be a large gap between the 4th-5th Shift, difference of 400rpm, 111mph vs 118mph

 

GearX sells a strait cut Final Drive.Much strongr than helical ones. You should get in toouch with them. Get in touch with "KIWI" on this site for more info.

 

would that cause 5th to grind?

 

Being straight-cut doesn't make it stronger. Stronger = Material/Treatment.

No, it shouldn't

 

i broke my stock b16 final drive!!! im now rocking the jdm 4.7. mayb u should get sum good tires son

 

Good tires will just make his problem worse if he continues to use stock parts.

 

[QUOTE=MFactory;37853736]Being straight-cut doesn't make it stronger. Stronger = Material/Treatment.

Hmmmmmm Here we go again...
Perhaps we should refer the readers to the Irish Tarmac Rally forums where the Weaker/ Stronger argument was thouroughly hammered out when we introduced our Straight cut Final Drives to the Irish Tarmac Rally Scene...
The " Straight Cut is no stronger" argument died down to a pathetic whimper as more and more experts piled into the argument, and the nay sayers slunk off with their broken parts and bruised egos to do some damage control.
We proved that Straight cut gears and special WPC Surface Treatment did handle the extreme shock loads experienced in the Irish Tarmac Rallys that were causing opposition brand gears to fail with painfull regularity, and often after only very short distances.
GEAR-X is without doubt the brand of choice in Road racing and Rallying and with more new products coming out this year will continue to be the choice of real racers.
Oh, and the sound of the Straight Cut gears is cool as well!

Oops!!

 

Straight cut CAN be stronger, but simply changing to straight cut with no other changes won't make it stronger. I have a theory that it will make it weaker given that NO other changes are made.

 

[QUOTE=KIWI;37862024]First of all, you don't have a clue as to the reason why everyones gears were breaking (ours were NOT the only ones to break. Every single manufacturers gears have been breaking on Irish Tarmac, including yours).

You want to know the reason? It's called driver error + torque multiplication + irish tarmac. If you still can't figure out the reason why from that, then instead of relying on a plumber to sell your gears and provide you with knowledge (who has limited knowledge in the first place), try asking our 20 year rally veteran why they are breaking. Also try asking our 2008 Irish Junior Rally Champion why he didn't break a single gear?

So instead of just posting your "sales spiel" as usual (when you shouldn't even be marketing your product on this forum), learn about the product you are selling.

Straight cut gears don't make anything stronger. The only thing that can make a gear stronger is the material & treatment.

Strength dictates the impact resistance of the gear, which tooth profile has sweet F all to do with. Toughness dictates how durable the gear is, which is a combination of material/treatment/tooth profile.

If you don't know the difference between Strength & Toughness, then what can I say..... lol

Straight cut CAN make a gear more durable as tooth profile dictates the contact/mesh ratio of the gear teeth. However, on a 4.928 Final Drive Gear with a Module of 2.25-2.5, a tooth profile with a 15-17deg angle provides the optimum contact ratio.

Don't believe me? Run the CAD for your straight-cut final gear in Solidworks/Cosmos then get back to me.

Seriously Jeff, I have no problem whatsoever with Gear-X or Special Projects, and I didn't even mention your company/product. I just stated a fact that "Being straight-cut doesn't make it stronger. Stronger = Material/Treatment", which is true. Why you had to mention about gear failures and why your straight-cut 4.928 is the end-all-be-all, we can all guess the reasoning behind that and it is certainly not welcome here, especially seeing as it is off topic as well.

In every one of your posts, even without mentioning MFactory, everyone knows what company/product you are trying to talk down on because you make it so blatantly obvious. That is on top of all the Sales Spiel that you mix in with it at the same time. People aren't stupid Jeff. How many warnings is it you've had now from moderators?

I sincerely hoped that you wouldn't start this again, so if you delete your post, I will delete this also

Oh yeah Jeff, one other thing that your plumber may have forgotten to tell you. The 4.928 Final Drive is not Homologated for Group N. Infact, you're not even allowed to change the Final Drive on the Civic EK's. You're fine with the EG's though. Peace

 

Watch the personal attacks, lets keep this thread clean guys! Thanks

 

Thanks Steve, have edited out any personal attacks. Purely stating facts, and trying to get it back on topic

Same old stuff ... Indignant outrage... If you can't blind them with science, Baffle them with BS!....:[/QUOTE]

If that's edited, I'd hate to see what the real personal attacks looked like!!!

My post was in answer to your as usual, arrogant and sweeping statement posted imediately after someone even mentioned GEAR-X! Is that not what caused you all the Grief on the Irish Rally Forums?
I merely stated some facts that might give a different perspective than what you ram down everyones throat at every opportunity! on every forum! And I never mentioned your Brand, or your company. Youre right, were not all Stupid!
Nor did I engage in personal attacks!
As for Disabled Plumbers? I have no idea who you are talking about, but don't be surprised if a good slap up side the head does not come from the next disabled person you meet... As a Veteran, I find no humor in your comment but typical of the arogance that will one day bite you in the *** my friend.
You are correct- We don't know why gears were breaking in the Irish Tarmac Rally! But at least we tried to make a significant change to solve the problem, despite all the fuss you kicked up as to how we were wasting our time! So far we have been sucsessful, and for the time being our WPC Treated Straight Cut gears are holding up! I know of no GEAR-X failures so far... Don't worry Folks I'm sure our friends will gleefully let you know when we have a failure.
Now that Mfactory are following our lead and using WPC and Torco lubricants perhaps you too will have a little more success.

lol. Here Jeff, have a

P.S I did not mean any disrespect to anyone that is disabled. I apologize for mentioning that, have edited my post, and have personally apologized to the person concerned. Jeff, maybe you should talk with your distributors more and find out more about them. I guess I know more about your customers than you do

 

[Changed my mind. Don't want to be in this. Too much to be said for both sides of the argument, and whatever I say is going to reflect the community's overall ambivalence and indecisiveness.
