Alfa Romeo 105 type CRGK update

On our last entry, we have informed you that the new CRGK for 105 type Alfa Romeo is in development.

It seems our CRGK / Transmission specialist Mr. RS has made some progress since then, and here's the latest update.new


If you are familiar with Alfa cars, then you should know what this is...

Yep, it's a prototype Shift-fork (Selector fork).good

More than 50 years have past since the original transmission was introduced, we are trying to revive it by using better materials and applying the modern technology.


A bracket is also in development along with the shaft. This CRGK will have a shorter shift stroke compare to the original one.

It might take a while before we see the complete kit since Mr. RS is quite a busy man.  But sure to inform you with more updates in the near future.

Don't forget to check back the weblog as often as possible.wink

OS Giken history class

For today's class, let us go back in time to learn how OS Giken started.
(Don't worry, I'll make it brief to avoid any tears of boredom...)coldsweats01

Although OS Giken is mostly known for the performance clutches and LSD's by many, it made its name by developing its original DOHC 4-cylinder 4-valve race engine in 1971.  As a matter of fact, our very first product sold to the public was this race engine.


In 1981, the legendary DOHC L6 24-valve engine "TC24-B1" was created.  We actually had a press conference to advertise the engine, and this was unheard of at the time for an aftermarket parts manufacture to have a promotion in this scale.   


This photo was taken 30 years ago.  You could see the Big-Boss himself talking to the press in the center of the photo.camera


Here it gets interesting.  TC-24 was an amazing engine, however, no clutch could transmit its power to the transmission at the time... so we developed performance clutches to take care of the problem by ourselves. 


Now that we have the clutch to transmit its power to the transmission, next step was to transfer the power to the wheels... so we developed SuperLock L.S.D. to take care of that problem.


The rest could say the same for our other products, and all was started with the TC engine and for TC engine. 

All Hail The TC-24paper

In stock now!

Good news from our transmission division.notes

Mr. S informed us that long waited out of stock parts have finally arrived.


Here they are, Slider (Dog ring) and Shift fork (Selector) for OS-88 Sequential Transmission.

They are expendable items, however, somewhat difficult to mass-produce.
As a result, we always have a limited supply of these items in stock, and limiting how many OS-88 unit our technician could assemble.

Come to think of it, it has been 9 years since OS-88 was first introduced.
We have sold over a couple hundred units thus far, and now many units are requiring overhauls and are taking parts away from new units to be assembled...

Mr. S aplogizes for letting many of you wait for your own OS-88.think

He'll do his best to send them in your way ASAP.
If you haven't order yours yet, then you should do it at your earliest convenience 'cause it is first come first servesign01

Mercedes-Benz Mclaren SLR

Hello everyone, this is T writing.happy01

OS Giken has LSD's available for many of Mercedes models, however, has never crossed our minds to have one available for such a rare model... Mclaren SLR until one of our customer requested for his own.


A rear member (picture above) looked to be made out of a duralumin material, and many parts are attached to the rear member.

I have taken its differential apart for its measurement, and was shocked to find out that they use an open differential.coldsweats02  It is true that the vehicle is equipped with a Brake LSD, so they might thought that there is no need for a mechanical LSD... but I personally believe a super car like Mclaren SLR needs a high-performance LSD.


OEM differential (left) and our LSD (right) are shown in the picture above.

I have tested and found that there is a tendency for many of high powered FR vehicles to lose traction on right rear wheel first when accelerating from a stop.  When it happens, the traction control system will kick in.  For Mclaren SLR, the brake LSD will kick in first to control the wheel spin, and then the traction control will control the throttle.  This is good for the safety, but not so good for... car dash


With our TCD installed, the vehicle could send all of its engine power/torque to the ground, and could take off without the interference of its traction control.  It also improves high speed stability.

I highly recommend our LSD for all the high powered vehicles, but not recommend anyone to be a speed demon... bleah

Drive safely.

Ferrari 550 Maranello LSD

Hello everyone, this is Mr. T from OS Giken LSD lab.

A customer has requested to build a custom LSD for the 550 Maranello awhile back.
It sparked my interest due to its original design, so I built one without considering its cost...moneybag

OEM differential has such an unique design that it bolts onto a carrier by placing an external ring gear in between.


Above picture is the custom made LSD for the 550 Maranello.
OEM differential was designed to attach an external ring gear, so I also designed the ring gear (see picture below) for the custom LSD.


Here's an installation picture.  The customer was 120% satisfied with the custom LSD's performance for greatly improved traction.
This 550 was equipped with twin-turbo V12 engine.


It seems many owners are experiencing similar traction problems since I have recieved more orders than I have anticipated...bearing

It's finally over

The 2011 SEMA show is finally coming to an end.

They are all burned out...

Thank you all for made it happen.

She is such a cutie, and her presence alone makes a huge difference for our booth.


With her presence and our "OS Giken the ride, the second day was also a success.
Let's hope we could say the same for tomorrow.
