OFFICIAL transmission, LSD, gears, final drive, gearbox upgrade thread!!


i recently bought a mugen 1,5way lsd,(for b18c) any info on that one blinx? thanks
 
mmm, sorry i don't know anythign about that one, i have a feeling ragingangel might know though...
 
I've got a doubt...I am looking for a LSD for trackday/fast road and would like some feedback...my car is a EK4.:drive:

Normally when we see any car that still does any street duty, we recommend the helical.

This is mainly because the plate LSD requires special fluids for proper operation (noise reduction) and beyond that, it will require maintenance every 2 years (estimated - mileage varies from user to user) in form of a rebuild.

The Helical needs no such maintenance/special fluids, however, you do give up some performance as a result. Depending on your needs, the helical may be more than enough for you.

Well my interest it's mostly on your products, but the info about them in your site are vague. Can you please tell about the specs of the helical LSD? Are they 1.5way? The car it's mostly for track day/fast road/moutain racing...:thanks::thanks: Sorry about my english..:(
 
Only Plate Type LSD's have a "way" type.

A helical LSD (which is in a constant state of torque biasing) functions very differently from a Plate Type LSD (which works on the principle of locking up)

Thanks, thats one thing i've learnt today.:woot:
What about the percentage of locking?
 
A helical LSD does not lock, so there is no %

A plate type LSD, it depends on the brand. With ours, it can be adjusted between 60%/80%/100%
 
A synchro ring is basically a brake pad for your gears. By increasing the friction on the inside of the ring (i.e the carbon lining), the ring will slow down your gear more efficiently/faster when you shift.

This results in faster/smoother gear changes.
 
Hi.
For a fully stock EK9 Civic Type R.
Only has Spec R manifolds and full mugen exhaust.
Thinking about the spoon Ring Gear 4.643. What else will i need to add. Carbon synchros to secure the gear box ?
Will it show good difference on 400m race with other CTR's due to faster vtec kick in and gear changes ? I just want to go spoon to keep everything japanese on my car if you get me :)
thanks.

Product here:
Ring Gear 4.643 - 41233-EK9-216

i don't get it, you want to pay more money for an inferior product,, I would go with Mfactory, most Japanese stuff is not actually made in japan anyhow....

as for faster vtec kick in, once your in vtec in one gear your in vtec, makes no difference, changing the FD will allow your car to accelerate faster than before in any given gear like for like, have a play with the mfactory transmission gear calculator in their site its most useful,
 
Hi guys!
I am building a race eg6 for circuit, hillclimb racing!
What would be the best 1.5way lsd for me?
Any experiences in racing? how much should be locked?
There is some new carbonetic lsd that has carbon plates,
and it writes, that they last longer, are stronger and everything better!
Is that really so much better?
They told me, that Kaaz is pritty agressive, so carbonetic is better with its progressive function..
So what are your experiances? Which lsd do you recomend???
The car is just for racing!!!
regards

If you do some searches on the carbonetic carbon LSDs, you will find that the carbon chips on the discs tend to come apart and cause destruction of the LSD AND the transmission.

My friend experienced this on his DC5-R. In short, it was a catastrophic failure and ATS/Carbonetic give him a "sorry about that..."

The technology and concept is very unique and advanced. Maybe in a few more years when it matures some more and others have better experiences with it would I revisit and reconsider this type of LSD.

If you're hillclimbing you'll probably need some assist under braking as well but this also tends to depend on your setup and your driving style. Most of the fastest FF cars use a 1 way LSD that remains as open as possible under braking or off throttle so the driver can position the car as they see fit.

We produce a very good Metal LSD that you should consider with all forged components at an affordable price point.
MFactory Competition Products - Forged Transmission Components

Our plate LSD is adjustable due to the cam settings. That said, many still consider the metal LSD to be the ideal setup for FF cars because the aggressive lock up allows for a more direct and instantaneous transfer of power to effectively drive the car in the direction you wish to go.

Having gone from a helical LSD myself, I prefer the metal LSD for its direct and responsive nature. For competition purposes, I would only recommend using this type of LSD.
 
My primary racing will be circuit and then hillclimb, becouse I fall into the group under 2.0litre engine in hillclimb and under 1.6litter engines in circuit racing..

So you are even saying, that you would prefer 1.0 way over the 1.5 way?
Everybody is having the 1.5 ways, so what to do?
 
I can't tell you what to do because like suspension everybody has their own preference.

I prefer the 1.0way because of the advantages I stated above.

Just because everybody has the 1.5way doesn't mean the 1.0way isn't effective. I'm not stating which is better, because that point is moot until you get to try and drive it yourself.

But I will state this, if you are more experienced in racing, you will appreciate less interference from the 1.0way...but if you're just finding your stride, then you will probably like the 1.5way's "assist"/stability under braking.

Fill out your location by the way.
 
I talked to some mechanics today, and they asked me, why I am not using simply the dc2 lsd...So I want to ask you, becouse you have allready try the differences...
Is there such a difference?? Is it ok maybe to buy a helical diff?Is it worth to buy a plated diff? becouse those questions make a quite variety of prices!
 
The DC2 LSD is very mild. Does it work?

Of course it does. But since you are building a car for competition, the DC2 LSD will not provide you with enough of an instantaneous response as a metal LSD would.

If the DC2 LSD was as effective as your mechanics have led you believe, then we would not be able to produce an alternative for customers who are looking for an added advantage.

Just a simple reference to any SERIOUS front wheel drive racecar and you will note that 90% of them use and prefer a Metal LSD for its ability to positively transfer power under a competitive environment.

RagingAngel you have my full attention, can you provide details as to how it is better over stock lsd's. Specifically the "feel" I guess is what I am interested in your perspective on.

I personally feel something strange when the LSD is searching for grip, its almost like its reacting to slow at first then starts to catch up to where it should have...can feel the steering wheel "sawing" as the wheels gain and loose grip with the stock LSD...its hard to put into words honestly. I do feel that I need to slow my pace down a tad to allow the LSD to do its dance. Do you think this that I am feeling with the stock LSD could be solved with a metal LSD?

Thank you in advance for your reply.
Larry
