[group Buy] Acpt Carbon Fibre Tailshafts Any Model! $1400us


Recommended Posts

Wow, what a read.

Fingers crossed all this gets sorted. Bad luck for the thread starter, he will probably never attempt such a thing again. However, organising a group buy is a whole lot of effort on one persons shoulders for no gain personally, so chin up hopefully this shamozzle wont put you off them forever :thumbsup:

New shaft is on its way currently, will let you all know of the outcome. Better be balanced properly...

sweet good news! glad you got your problems sorted, i think alot of us are still yet to try them? i should do it soon but i am going to take it to a balancing shop before i attempt to use the shaft considering the problems that have happened.

as for the last post.. your right! i feel bad for dragging everyone into this mess!! i thought a carbon shaft would be a good addition to my pile of parts.. wasnt i wrong!

Yes but does it fit...is it balanced..

I'm too paranoid to take mine out of the box...tailshaft balance shops are as rare as hens teeth over here. Anyone i ask here just give me a stupid look and ask ,why did you buy an unbalanced shaft??

Andrew ..not your problem mate...reckon its pretty dodgy customer relations from ACPT, the been great on the emails but bloody slow as for delivery. At least its not as slow as an engine build, my engine still hasnt come back from maching but any day now..

This week i'll be refitting my stock shaft to see if this vibration goes away. Part of me hopes it does..... Part of me hopes it doesnt. If it does another long cardboard box will be on ACPT's doorstep. :).

Shaft is out. Stock shaft is in. Vibration gone. ACPT is getting their shaft back.

For the guys that have sent their back... how did you go about this? Who did you speak to? How much was postage?

shit this aint looking good, i'm not sure if anyone sent theirs back yet??

i'm going to bite the bullet when i have a bit of spare money and go get it balanced..

Andrew. Are you going to get your balanced here in Australia? (If it is out... Hopefully it isnt). What happens if you get it balanced here and somehow it breaks in half. Will ACPT come to the party seeing that you modified their product? We shouldnt have to get these things balanced.

Food for thought :)

My god, what a read! I feel so sorry for you guys and especially you Andrew, your a good bloke for keeping your head up, most people would have just given up. Hopefully this all gets sorted out, but damn, what a bunch of f***ing c***s is the US for pulling this shit. Fully agree that they are lucky they are not in Aus......

perhaps just get it checked to see if it is out of balance or not..

theres a balancing shop round the corner from me in bankstown, when and if i ever get my motor back and installed i will take the shaft there once i have the car running. i want to do a before/after comparison

but this is problably a few months off now..

Yeah I'm the same Andrew, just got my block done now head has been sent off for maching so gunna be at least 6 weeks and probably early may sometime befor it all goes into the car. Finding a tailshaft balancer is like a needle in a hay stack here.

Well the light at the end of the tunnel seems to be the sun and not a locomotive. The Shaft spun up well and the dimensions are within spec but....

At the front, a ring had to be machined up to sit between the adaptor and the locator on the front of the shaft. The adaptor supplied didn't locate on the front of the shaft very well as it would have only been bolted on through the 4 nuts and bolts.

More nonsense on the rear. The adaptor supplied (right hand side) was machined up to locate on the centre of the tin plate on the end of the tail shaft. The adaptor that was machined locally (left hand side) locates using the outside of the shaft.

Now comes the good part. :wave:

What's the good part Mr Keets??

How much did that all cost to be machined up???

I've got buckleys chance of getting it done here in ping pong land!

^ Mark. The good part??? it's finished and the car drives. Cost, a lot less than it's going to cost you in Japan lol. Let me know if you need something machined mate

Well this is it guys... JOB DONE !!!11ty!!!

Run 60 = 430.5 pre shaft, original tune from the middle of last year

Run 63 = 428 Shaft installed...running fat

Run 67 = 433.9 Shaft installed...basic tune, probably more in it but this isn't for sheep stations.

It's hard to say if it feels different as I haven't driven the R for quite a while. But the comparison says it does. Was it worth it? lol. Personally I believe if you continue to pursue the small gains, especially the more cost effective ones :banana: , they add up to decent gains. Well that's the plan anyway

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
