Hi,

So I've installed a carbon fibre tailshaft and it appears to be not balanced correctly.

The vibration occurs at anything over 80km/h and then gets worse, 100km/h is not very drivable :(

It is an ACPT shaft and was not part of the group buy.

The seller is offering some assistance as the shaft was checked and supposedly ok before I received it.

RE Customs installed the shaft.

Is there anything obvious that could go wrong in the install? From what I can see you just bolt it in...

Also, does anyone know where I can get the shaft balanced in Victoria?

Thanks,

Gareth

I take it you've read the ACPT thread (GB section)

There were a few places in there i think that did it.

End of the day though, they were not repairable I think...

Hope you get it sorted dude...

Yes, that is what worries me :(

I have now read the thread and finally the seller has replied to me. He did get it checked in Adeleide and they advised it was balanced, so I'm getting RE Customs to take another look on Tuesday at it, and check the balance if possible. The seller has offerred to look at the quote for getting it re-balanced. RE did have some issues with 4 bolts been two long, so I'm hoping it's a minor install issue or something a tiny bit out and it can be fixed.

On the positive side the driveline clunk / sound my skyline always had is gone and the acceleration is smooth, until I hit 80km/h :(

Also I appeared to have spelt carbon incorrectly while at work (too much multi-tasking)

Futher research shows that the picture of the shaft is from the group buy, its in fact the same image sly33 had when he bought the shaft. I haven't checked the serial numbers to confirm if its the same shaft yet. RE Customs will confirm if the balance can be fixed or not, I did notice one person did manage to get it fixed so I can only hope I can get it balanced and working.

Or that the modifications RE Customs had to do to the bolts to get it in went wrong, which is unlikely.

So....where did you purchase it from?

curious if this one shaft has been floating around for 2 years with no-one able to get it to work?

I hope not!

kn6gtr who appears to have bought it from Sly33. It was claimed to be brand new and it appeared to be completely unused. In fact it would make sense that it was never used if the mechanic had to cut the bolts because they were too long to fit!

At this stage I'm going to ask RE customs to get it balanced and just hope it works, I'll update the thread on Tuesday evening.

that was sort of my impression from the group buy way back - sorry to hear :(

Yes, I wouldn't have bought it if I knew it was from the group buy. Seller did say he will provide a refund but I'm waiting for the money to actually be in my bank account.

Until then I'll be checking for progress updates with him pretty soon :)

    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
    • I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.
