Merli Posted January 4, 2009 Share Posted January 4, 2009 Gracias... I'd better get off my ass and try to fit this thing. If I need to get a custom spacer made up, I'll be having words. OS30GK: Can you please confirm that the OUTSIDE DIAMETER of the 2000hp shaft should be 9.6cm? Can anyone else provide the correct LENGTH of the shaft, from mounting point to mounting point?

elrodeo666 Posted January 5, 2009 Share Posted January 5, 2009 Took mine out to HKS to get an independant professional measurement and mine was 9.5 cms and thats a 2000/lbs shaft. There were couple of spots just over 9.5 and other spots just under. We took 10 measurements equal distance apart up and down the shaft. So where to go from here???

wrxkilla Posted January 6, 2009 Share Posted January 6, 2009 Just measured my R32 GTR 2000 lb/ft shaft and diameter is 9.7cm. I still have vibrations after changing to another set of wheels, so will look at re-fitting stock shaft to see if that is the cause....

elrodeo666 Posted January 6, 2009 Share Posted January 6, 2009 I emailed them yesterday and got this info from them..... I have attached our assembly drawing so that you can see the length of your R33 driveshaft. With both adapters on, the driveshaft should measure out to be 44.72" from end to end. Also, 9.5cm is equaled to 3.75" which is exactly where the tube should be. I understand your concern and If you have any further questions, feel free to contact me anytime. James Martin ACPT Inc.

James Martin ACPT Inc. nice of them to send you the drawing. it might be worthwhile getting the 32 GTR one as well for merli etc so they can confirm it's all sweet before install. kind of a customer implemented QA.

wrxkilla Posted January 8, 2009 Share Posted January 8, 2009 yep it does sound like a balancing problem. Though I would have expected they have a QA process of sorts... I have just removed tonight, can't be arsed fitting stock one, will do tomorrow and let know the results. Will be both happy and very angry if my problems go away with removal of the shaft... Anyway chaps, heres some pics for anyone interested... PS anyone have the assembly drawing with specs for 2000lb/ft R32 GTR shaft?

wrxkilla Posted January 12, 2009 Share Posted January 12, 2009 Hey guys Okay the source of my very severe vibration in the car when travelling anything over 90-100kph (which is a major problem when the car does over 200kph on every lap of the circuit and does the drags at 200kph) is............ THE ACPT CARBON FIBRE DRIVESHAFT ! whooohooo. I'm so happy! NOT. FFS. First I pay a reputable garage to fit the shaft. Then I remove it, and whooshka, problem goes away. But just to be certain, I re-fit the CF shaft to ensure correct fitting 200% ! - Problem come back identical. Remove again, and problem gone. What a peice of Junk. Very unhappy customer that wan't his money back and will throw this rubbish in the bin... (On a side note, I can defo feel a little less responsiveness through the gears with it removed! lol) Cheers chaps.

YLD-CHLD Posted January 13, 2009 Share Posted January 13, 2009 (edited) hi again all, i have had experience in building & balancing driveshafts from modified trucks to cars & when i received mine was dissapointed with the balance weight & the way that had been attached(photo to come) it was for that reason that i havent yet installed the shaft until i have personally balanced it at my former work.I will be removing there weight after intial balance & weld on some purpose made weights not a peice of sheet cut out & rounded to suite the shaft. Also with a steel shaft if u go about the preparation thourougly u rarely need to use weights,& if any not of the size i have on my shaft. OK thats my rant ,going to get pic of balance weight.
