Cheers Russell..

Hey Justin, did they give you any time frame??

When are you expecting it to arrive???

[justinfox]

Should be here fast. 3 weeks max I hope.

Giant you are running the bigger 2000ft/lbs CF tailshaft yer?

General rule of thumb for removal of rotating mass is for every 10kg of rotating mass you take out has the equivalent effect of taking 100kg out of the car.

How much was yours Russ? PMme if you want..

I wonder what the price difference is between the one Justin got and Russ' one...

[blk180]

I think it was about $400 dollars differnce?

i run a one piece carbon tailshaft, and it is almost half the weight and we spin it to 8200 rpm also its rated to 1500 hp.

cheers russ

p.s we also dont have problems anymore with driveline shudder from the centerbearing on hard launches with the carbon one piece shaft.

hrmm. thats exacly what im after. mine shakes and wheel hopps heaps bad with my new nismo tripple. oh and my shaft is worn out. lots of backlash in the joints

Any update with the carbon tailshaft Justin???

[justinfox]

It's not here yet. Ordered it a while ago now, still waiting for it.

dave, if you don't want to splash out on the carbon shaft get one of johnny's one piece chro-mo shafts. still around half the weight of stock, and one piece but like 1/3 the price of the carbon job.

that's a huge generalisation. rotating mass has much more inertia if it is far away from the axis of rotation. most of a tailshaft's mass is an inch or two away from the rotational axis, so lightening will have minimal effect.

most of a wheel's rotating mass is several inches from the axis, so lightened wheels would make a bigger difference.

But the tailshaft spins a lot faster than the wheels.

Update??

[justinfox]

Still waiting. Did get a letter in the mail from them which had my invoice in it!

[justinfox]

I've got it!!! It came last week. I got pulled over by customs and had to pay $500+ on tax on top of the shaft + shipping

Anyways, busy busy won't be going on the car for a while I will post again once it's getting installed, with pics of-course

[Beer Baron]

PICS DAMN YOU!@!@!@!!

[justinfox]

SERIOUSLY SOO BUSY NOT EVEN TAKEN IT OUT OF THE BOX LOL!

[justinfox]

OKies just for you Richard

[benm]

Maybe it would be good to throw your car on the new UAS dyno very soon, then have this installed and get it dyno'd again on the SAU Dyno day coming up soon?
