The boys changed the transfer case on saturday in the hope of getting some front drive. Didn't help much, the best they could get was 10% or so directed to the front. That's why you see pics of it black-tracking everywhere.

Aha.. That makes sense. It certainly looked like it was having traction issues!

yeah, there is something not quite right with awd. not exactly sure what but it's not getting enough front drive. we changed transfer case on saturday and it was a little better in the morning, but not much. mark reckons possibly a sensor failure or awd ecu not receiving an input (like TPS) as it's getting some pressure but not enough, which means it's baking the transfer case which means it gets worse and worse. on top of that they have a fair bit more torque than before and trying to put that power down on 265 semis is not easy, hell even some of the evos which are much lighter and with less toque run 285s!

the car went so well for it's first outing. nothing broke and apart from the little awd issue it ran absolutely perfectly. a credit to mark and russ for their hard work and all the other guys who worked on it too. mark drove the absolute wheels off the thing too and watching the in-car last night just goes to show he must have a giant set a it looks scary to drive. scary fun that is.... :banana: i'm sure russ will post some when he gets home, but i'd say the car is wheel spinning about 3/4s of the time! It's sideways from turn 5 all the way up the hill and onto the bridge through 3rd and 4th. then sideways off the bridge all the way to the S.

and yes cnj tune it.

We had the same or similar problem when we were running the Autronic ECU...it needs a voltage divider buffer circuit fitted to allow the attessa to share the same signal as the TPS without pulling it (the voltage level) down under load. The Vi-PEC had an issue too but was a much less complicated fix.

Hi Guys

well back from superlap,

and all is good, car is still in one piece and running great!

obviously have alot of things to sort through and keep building the car as it wasnt really finished ( but are they ever).

we need to get the 4wd drive sorted asap!! thanks for the advice paul will be looking at pressures and codes etc pronto. then off to get swaybars made as nopne were on the car for superlap, and

bump steer arms for the front end. then different diff ratios wilkl be changed as we couldnt use the torque to full advantage as we had too shorter ratios top speed was 250 down the front straight on the limiter before the start finish line!! ( we kept raising the limiter but far from ideal)

thanks for the comments

cheers russ'

here is some incar

Awesome incar Russ, just loving the power on oversteer :down:

The box is a Holinger?

Mustve felt good passing your old R32

it's a stock box, but with an ebay short shifter for quicker shifts. works well. :bunny:

seems as though you have the Tomei 1 gear set. had a look at ratios today and your ratios are quite close compared to mine which are the -15 gear set.

Still have some setting up to do, comes on boost nicely.

Keep up the good work Russ and crew.

All the best, and always keep in the loop with the development advancements. Good learning experience for us non circuit boys...

Hey Guys

We shot Marks car over the weekend and the feature, along with Superlap will be coming out in Motive DVD volume 2 which is due on shelf in June.

Motive DVD Volume 1 is based on the Red BUll Drifting World Championship and will be out start of May.

    • Actually,  just remembered there should be info in the threads (somewhere) about swapping to a manual steering rack and deleting power steering all together. 
    • Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open
    • Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.
    • I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂
    • Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
