But long L6 motors will need to be appropriately damped. Skyline RB26 oil pump destruction in related to this, and so are dead 2JZ's that go with an aluminum pulley instead of a lighter crank damper. Hint: ATI is a 2JZ's friend.

Yes, this would be a practical example of how the harmonic effects are greater the further you get from the flywheel.

I was referring to a purely performance standpoint, I should have included a reliability view too. ;)

My notes/opinions...run a damper. I'd rather have vibration control than to shave a 1 lb from a 3" radius. A balance lightened flywheel will do more without endangering the bottom end. Also I'm looking for some interesting data that ATI or Fluidampr had posted where running the larger and heavier pulley actually made more power ;)
The logic is easy.

As for the old Greg's comment on the Subaru crank being stiff, have you seen how thin the throws are on them? I wouldn't say they are SUPER stiff but wouldn't call them stiff, especially as the stroke increases and journal overlap is reduced.

omg... i want that clutch... had that on my s13 silvia... ATS&Across make fantastic products

I didn't read anything in here but I also had an ATS carbon twin plate clutch in my 1JZ S13 for years and it is one of the best setups I've tried.

It looks like they are releasing a LSD as well (translation needed):

Leave motor stock.....invest in r compound tires and track days.....profit?

After years of modding cars, i realize now where money is well spent.....

Im all for mods but drive the car to the limit and then upgrade....

※ clutch & LSD for 86 & BRZ, in popular now accepting reservations!
※ The first 100 units / LSD clutch first 100 units (total 86 & BRZ)

лучше в синем, тогда все с разу купят. ага.

huh ?

Carbon LSD for 86 & BRZ has arrived.
We were teamed in the original setting rack for use in the rally through the cooperation of Mr. ATS.
I think this is so we assume the Tarmac, and what is available and will pass like everyone, until the mini-circuit and high-speed circuit.

With the concept of changing the run up to now is completely different in taste effectiveness does not mean that because some carbon is all your choice. Troubles many people have been received in the user's settings and ran up to now even if the metal LSD.
Want to control the ON and OFF behavior change mostly I want Kiki firm.
This can not be stable running of the vehicle behavior is distorted by repetition of some of the accelerator also partial ON → → OFF during cornering.
We stepped on the accelerator hard by rapidly starts working at Okuseru ON at the rising edge of the corner.
I think the main corner in the setting of low speed to increase the initial torque and more often than not in the circuit-intensive, high-speed corners are too many I also resistance.
You'll want to use the almighty to high-speed circuit from the street if possible Desuga LSD setting is to run according to the situation of course.
It is a carbon appeared to be LSD here.
Less initial underscore, but may be faster circuit ideal LSD and still are very little chattering ·
Some of you it is not a mistake I would say is even more effective against metal Bakkibaki Yappari But even so, I like it that way.
Gravel is put, is the world of the unknown without any data to the manufacturer http://emojies.cocolog-nifty.com/emo...ldsweats01.gif
I very much LSD is mild LSD is a metal of 2WAY, because the high initial torque of the times too? ? ? What I thought from http://emojies.cocolog-nifty.com/emoticon/happy01.gif
There is also a period not covered at all to the trouble a lot in the carbon LSD early in our honesty, so who improved Mr. ATS that will allow the situation now, we pride ourselves with our customers with peace of mind.
I think a very good and you use it more just because LSD Street also offers a significant improvement over straight, especially if the car FR.
Is popular and was really well received, but has also been installed in our LEXUS something.
Please see this all means because there was a video of the HP ATS.
