Phillip Island 16-06-2013 After a wet start in the morning the day got better. Still very cold, had a lot of trouble getting heat into the tyres. Couple of issues spun the rear yoke in the tail shaft

Some in car from WRX/SAU track day at Winton over the weekend...

First up is my fastest lap in the last session of the day....

Next I have uploaded the whole last session when Russ and I were pushing each other to get PB's. Managed to get two 1:35 laps in before the rears packed up and went home - as Russ can attest to the middle of the rears were bald. The 'unintentional' drifing starts around the 4:50mark....

Finally, the off....quite clear what happened, was in 4th at around 170km/h (indicated by the speedo) hit the ripple strip on the inside which upset the grip and sent me understeering off the track. Naturally being in 4th I didn't have the responsive boost to pull me out of it and I was just a passenger. Russ was the car that went past after the white Emo soon after I *eventually* came to a stop....

Enjoy

Not sure you overtook enough cars! So , feedback on the wang? I am looking at perhaps getting a different aftermarket R34 wang to try on the boot lid after my car gets a few more hours on it in the coming months

Without actually seeing the wing, wouldn't it be a little low relative to the roofline if you can sit it just up there in it's own flow then It may be more effective ?

Wing DEFINATELY works, no two ways about it.

First few runs of the day I had the wing set to maximum angle and was getting understeer under the bridge, much Much worse than I normally would with the GTR wing and Nismo boot lip. i did at least 50 laps in this config to make sure it wasn't just new tyres. The rear was much more planted, even exiting the 3rd gear camber change Hungry corner (the uphill left hander that I usually struggle at for power down traction due to the unusual road profile.).

On following runs I backed the wing off to 50% and the rear was still planted nicely, but the understeer reduced quite a bit, showing me the wing definatley works.

In fact, next project (after replacing the broken engine), is to make up a removable splitter to attach to my existing front sump gaurd/undertray, which will end up much like the alloy one on the Pulse Evo.

Hopefully with front splitter I will be able to dial in more rear wing and drive upside down in tunnels.

It is also probably worth mentioning that I couldn't see any measurable difference in top speed on the straight/into the kink (215klm/h or so).

This is the only pic I can find of the actual wing (at auction on the car I took it off).

That vid is almost humorous ,,, but I can assure everybody there was no laughing at race end.

Bloody crap clutch setup stuffed what should have been a good weekend.

I contemplated doing a change over night for about 10 seconds but Wakie in winter would kill us both.

Oh ok, see that wing in itself looks to be fairly high, glad to hear it's giving you a real tangible difference to feel and time too as you often see people wasting money and going backwards with aero, I thought i'de just clarify what I said as I wasn't having a dig :) what i was trying to say that if the wing is higher up in the airflow, you may be able to develop similar levels of downforce with a less aggressive angle of attack, of course I'm only talking theoretically often what we learn at uni means shit in RL :D.

yeah hyraulics were fine. This was a brand new clutch to replace the old one which used to slip if I launched over 6000 (as it did at PI that day). Not exactly what I was expecting.

BTW I agree Marlin that wing would be effective. It is at the perfect hight to push around a car with an empty engine bay

      Need AC Compressor for R32

      By Zabuza · Posted

      Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.

      V36 2008 Coupe Wiring Differences with Android Screen

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      V36 2008 Coupe Wiring Differences with Android Screen

      By sausagepianist · Posted

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?
