I forgot about the ducting photos.

These two arent from an australian supercar they are from a current Newzealand V8 touring car.

They run a controlled Wilwood calliper and controlled brake duct.

Our local supercars use an almost identical ducting setup thats kevlar.

Hi sorry if I might be hijacking your thread, but this seems to be the best place to ask.

I drive a 99 R34 25GT, at the moment it's a daily driver but it's also a long term project car (Engine won't really be touched until I get myself another car for a daily driver).

I've taken it on one track day so far and I'm looking at taking it on the track a couple of times a year if that, nothing too crazy.

But I'm looking at upgrading my brakes with a big brake kit. I was looking at the D2 kits but I'm not sure what I should be getting. Can someone please give me a couple of options on what to get? I'm not sure on rotor sizes either. I'm hopefully getting TE37s soon also so they would have to fit under those..

Thanks for any help in advance

So is the air and water vapour mixture just directed onto the face of the rotor on that side?

The 330mm D2 kit is the safe bet, they will fit under most 17s. If you want the 355 you will need 18s, the TE37 design is great for caliper clearance and should not be an issue. Really, the question should be what size tyres do you want to run (17s are much cheaper than 18s) then choose the wheel, then choose the larger or smaller brakes to suit. Either kit will be fine unless you use the brakes more than you need to ;)

Brad, we need pics of the other side of the rotor...I'm willing to bet the vent runs to the centre of the disc not the outside face, but that's not how it looks in those pics

here is a couple from both sides of a VY taxi.

This car has a front mounted rack unlike the previous car that was rear mounted.

The ducts on this one are mounted at the front of the upright obviously.

The NZ VY has a very similar thing but smaller.

There is a carbon peice that locates onto the duct which adapts into a 3inch spiral tube to allow the flex before entering very similar kevlar ducting to the front bar.

The kevlar parts from that VY are removed at the moment and being repaired.

lots of space when there is no driveshaft going to the hub eh? Interesting the shape of that final duct, I bet they have done a lot of testing about how much air to aim directly at which part of the disc vs how much to direct at the centre

Real race cars only have two drive shafts Duncan ;)

I wouldn't want to change the ducts that's for sure. That car has done 3 Bathurst 1000 events and finished all 3 times as well as sandown enduros so if say they did something right.

The differences between teams is interesting to look at though.

A lot of the time they run the cars with the ducting blocked off at the bumper.

Spot on the money. There is a properly made up funnel that crates a neat shape that suit the inside of the rotor.

Jacking up a supercar now to take photo of it.

I see said the blind man! Great job Brad, thanks mate.

No kidding with space due to no driveshafts!!!

Anyone wants Alcon rear kit ? SInce they offer free shipping for rear kit, I will order it, and will keep it for spares, but I thought if anyone wants rear too we can drop price little bit http://www.jdl-brakes.com/alcon-adv-extreme-brake-kit-rear-4-pot-o350x28-nissan-skyline-r32-r33-r34-gtr.html

I got mine Alcons from JDL, great service and stuff

These seem to be pretty cheap http://www.ebay.com....=item2ec12dc8e3

Does anyone have experience with them?

I bought my first R32 GTR with Wilwood 330 mm kit on it. It was good, but not better than Brembo from R34 which I fitted few months later. Maybe I had some issue with pads from this kit, and that's why it didn't perform as it should. Anyway, I wasn't happy. It's still my #1 http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html

Those wilwoods are a very average setup overall.

The callipers have a terrible open bridge design and they flex horribly. The lug mounts they use also flex a lot if you dont have the callipers spot on centred to the rotor.

I've used them on lighter road cars like MX5's and pulsars in the past with little problems

I fitted a set up to a Toyota 86 a fortnight ago only to remove them after a track day and change over to an AP calliper. The pedal feel was horrendous at 3 corners at Wakefield park.

AP's being tested on Wednesday but already on the road they feel so much nicer under firm braking.

I have Alcon front kit with 343 mm rotors, but thinking about these kits http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html What wheel do I need to clear 6 pistons calipers with 365 mm rotors ? 18x9 +15 would be ok ?

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
