Hey guys,

I will be getting a custom made carbon drive shaft from diff technics Kogarah in 3 weeks.

I know the Z comes with 1 piece c/f standard and our stock is a 2 piece.

It will handle 1000hp so if I decide to go FI in future it wont be a waste. I was planning to get stillen gen3 long intake but saved the money and got this instead.

Any thoughts? Thanks

Bear in mind driveshafts that will "hande 1000hp" can still break well below that level if you beat on them enough. A guy I know is resurrecting a famous import drag car here in NZ. He had "1000hp" driveshafts in it but still managed to destroy one with a temporary motor making barely 180hp by dumping the clutch at over 8,000rpm with slicks, and the track was barely prepped. I think he'd done about a dozen runs with them.

Personally, I think a C/F shaft would be well down the list of mods for me, but I don't know your end goal or current mods, so if it makes you happy then go for it.

Why?

This is why, bear in mind that is an aluminium one, c/f will have less vibration and less weight, even more gain.

I dont think the dyno number is realistic since there are 16 runs in between.

But reducing weight and rotational mass will always free up more hp.

$1700 installed, could have been alot cheaper if the usd currency was higher. They dont make cf in shop, its an import from driftshaft shop in the USA

CF Driveshaft isn't necessary unless you're planning on dropping serious power and it's one of those things that you'd get when the engine is out getting turbos bolted on. We've got serious HP cars in the club who don't bother with them. Light weight wheels, flywheel etc will make a difference at the numbers that you're looking at. Bear in mind that the US is known for happy dynos.

      Breather for it. If it's anything like the GTRs it should run up to the top of a bellhousing bolt.

      R32gtr sputtering and stalling

      What basics? With these OBD1 ECUs it's not like the ECU will give you any real clues, it's not really doing any sanity checking of sensors/sensor data. My experience is actually a lot of sensors tend to be the source of the issue first and foremost, and checking everything gives you a direction to investigate. MAF/O2/STFT/LTFT should all kind of make sense. You can try little tricks of the trade like tapping the MAFs to see if it triggers a stumble, things like that. But once you've done a compression test knowing whether you have an air leak or fuel delivery problem is kind of hard to narrow down without sensor data. And you don't really know if all your sensors are making sense unless you can interrogate the ECU directly about what it's seeing for sensor data.

      Absolutely this. Yes, except not vacuum hose. Something oil/fuel safe is a better idea.

      Like a Stagea, but not as cool! Hope you have enough garage space for this, or is something going to leave to make way for it?

      My BMW E39 528i touring

      The new project has arrived. I have wanted one of these for such a long time, well before that meathead Clarkson drove one in Africa. I really wanted an E34 but I have some medical issues that mean I *really* can't bump my head and the lack of airbags in the E34 made it just too big of a risk.  I don't know why I've always liked these older touring BMW's to be honest, but man I love this car. She's been pretty well maintained for her 243k's with what appears to be only a single oil leak at the oil filter housing gasket. It has a bunch of updates including later model bumper and headlights, 7 series billion-way adjustable seats and it came with a few spares and another set of wheels with legal tyres. I got a unregistered car permit from the RTA and drove it back from Canberra on Saturday.                   First cab off the rank is cleaning it up for blue slip. I dont know how picky they'll be but I figured I'd clean the headlights, fix the oil filter housing gasket, replace the speed sensors (throwing errors) and swap the OE wheels (the M Sport wheels have a big chunk out of one of the tyres.) I also need to replace all 6 gas struts - 2 for bonnet, 2 for hatch and 2 for hatch glass. The car tries to eat me whenever i open any of these. My plan for this car; Ultimately, this is a budget car. I can't afford to throw lots at it and its because I have another car that I got this, if something breaks its no big deal. I will just maintain and repair it really. But eventually I want to do a manual conversion. It actually looks pretty straight forward for E39's and the trickiest part will be sourcing the parts.  I do need to replace some suspension arms or bushes because wow, she's a floaty old girl. She's also fantastically slow. Like really, really slow. When pulling back out on to the freeway on Sat after a quick pull over I needed to wait until no cars were visible before going.  Oh, and the guy I bought it from had a gorgeous R31 GTS-X in the garage.
