its cracked at the helmholtz resonator weld actually. Pretty big crack too, i need to get it fixed before the damn resonator sheers off completely...flexes a lot already

 

so any driveshaft updates

 

Only diff is price and vibration. CF being a but more forgiving.
Tomato tomaaato. Lol

 

edited for additional clarity

 

anyone else have their shaft installed yet?

 

probably won't be til may....getting other things ready for hellaflush

I think 808_G should have his on soon

 

Sorry for the late response, I've been extremely busy. We have been testing one for a couple months on our stock block momentum car. ~425rwhp 425ft-lb. We plan to install it in my car (~650rwhp 670ft-lb) once I get it back together.


I was standing next to Jon when he was talking with you. We don't plan to test, if someone insists then sure but its highly unlikely to see a difference. The dyno typically doesn't show much of a difference from rotational mass reduction (lightweight flywheel, even lighter wheels etc.)

Are these in stock now?

 

did anyone dyno their car after installing the carbon/aluminum driveshaft? With the boosted cars seeing some gains, I would imagine NA cars will show some.

Z1, how is the aluminum driveshaft holding up so far? can you discuss more on vibration?

 

Mine is getting installed right now along with a new clutch, I'll have updates later tonight.

 

cool. updates with dyno I hope.

 

so driveshaft is installed and so far impressions are positive, the car feels like it has a bit less resistance when accelerating. I can also report no abnormal vibration during highway driving or running the car at seed altogether. I haven't gone full throttle yet due to my new clutch, but once I put a few more miles on it ill give it a good go and report back. So far pretty happy, I'll prob also keep a tab on my gas milage as I expect it to go up a tiny bit. Cheers

 

Damn, was hoping to see some dyno results! Butt dyno can always be strong. I have a feeling this won't be worth it once it gets the before and after dyno.

 

A mod doesn't have to show gains on a dyno to prove it helps acceleration... shorter final drive gears, light-weight wheels, light weight brakes (and several other mods) are felt with better acceleration and not measurable on dyno.

After all these years the one thing I've realized more than anything = many people are dyno dependant (unnecessarily) <people can squabble of that statement all they want, I've seen too many lightly modified g35s drama for days over dyno (or lack of) - its not a say all end all, period

 

I never said a dyno result is the end all on if you are seeing gains or not. Obviously taking a car to the track is more accurate, but how many people are going to take their car to the track to measure the gains after adding something to their car?

I mentioned the dyno because a previous post was saying gains or 40-50hp were seen on a turbo application. So if that's true, then you would assume the gains would also show on an N/A application.

Either way, some type of quantifiable result is better than someone saying "it feels faster."
