If you are in no dire need of your four wheel drive system to work as sharply as it did from the factory then keep going with your existing transfer case. Like every other part of the car they wear out, and the more power, the faster :)

We have several rebuilt cases that we had done (new frictions and steels) that we swap out from time to time on the cars. The parts are available from Nissan :P

Nah, I'd rather refresh it to brand new standard as part of the general rebuild... As soon as I can get a price from ya, I'll check my calendar and see when I can get it done :laugh:

-D

EDIT- This is the link I was reading about xfer rebuilds and the corresponding prices for the parts http://www.skylinesaustralia.com/forums/R3...amp;pid=5227996

Ben, David has a PowerFC - in fact it is the R32GTR one out of the R that was written off in Targa Tasmania a few months ago (as his old one shat itself). And yes, it is tuned rich as FCUK atm while he fully runs in the motor. Mind you he is not out for HUGE power, as he has chosen response rather than massive numbers - he is running a pair of HKS 2530s - my favourite turbo :(

Andrew, overly rich mixtures can offer cooling & lubricating advantages but too much fuel can have adverse effects at the same time.

Excess fuel wash = goodbye critical bore cross hatching & hello glaze city..............not to mention that ceramic cats don't take too warmly to bucket loads of unburnt fuel. :)

Yeah I know Pete - I am not the tuner (Martin is) and I am not the workshop who did it (Manta is - and Steve has built a cubic SHIT-TON of wicked cars). I am sure they know what they are doing.

That said, David's power figure was not bad for low boost and everything taking it nice and easy on a full run-in tune. About right with little 2530s I would have thought - they only start getting up into their stride when they hit 18-20psi - I believe his tune was done at 12psi for now.

For those that were worried about what they saw coming out their exhausts on the day (black trails etc) there were very few if any cars that we could determine on there as being overly rich. A couple had a little too much fuel in the midrange, but nothing was actually drowning in its own fuel as you normally see from time to time at dyno comps. The black soot blasting out of the exhaust systems is normally the residue of cruising around being hammered out of the pipes by some high rpm airflow and heat. Black smoke on the dyno is normally a sign of a very gentle driver :)

cheers Martin for showing me your nifty calculation between the Dyno Dynamics and Mainline Dyno's

my previous runs on Dyno Dynamics Dyno were exactly along the same lines as in the graphs with the calculation.

Thats not actually a Mainline thing....and they dont really like me doing it...BUT

Having had a DD then swapped over to Mainline some of my customers wanted to see where their kw went (when in fact it went nowhere!) so I used the custom Math Channel function on the Mainline to write an 'Estimated Dyno Dynamics' correction factor, which as you can see works pretty well :action-smiley-069:

We also have a Dynojet HP Channel thing as the Americans really like to see their power readouts in 'Dynojet HP' and dont like kw :(

Good news is your car would make 500rwhp on a Dynojet no worries!

so martin what is the difference in percentage between mainline and dyno dynamics?

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
