Far out, ridiculously quick time! Congrats Mark and Russ

great to see someone go out there and put Mike Collin's WRX in its place finally! hehe but it is an awesome car and he knows that place like the back of his hand. so it really is an awesome effort to run those times for people who aren't that familiar with the track - it is a very technical little course.

That STi is an awesome package, I can see Michael pulling out all stops for the next round to try and break the 42.72 however. Will make for some interesting racing :P

yes, i am sure michael will be trying pretty hard to get the record back, but i was talking to him and he is building a pro class off road buggy too which is keeping him busy also.

michaels car is an awsome machine and he drives it super hard!

interestingly , we put a set on avons on the car for one run and took them back off as they werent upto it for our car, it appears the car is to heavy for them and they move around heaps on the sidewall which was costing time, we also noticed this at the maryborough sprints but didnt worry about changing them back .

i have a picture at home which i'll post and show you what the sidewalls were doing

just saw the results. official record for the AWD class is now 43.08 by Mark and 5th outright!!! There were 9 open wheelers there, so that's just an incredible result! Mark ran the 42.72 in the top six shootout at the end of the day - but that run doesn't count towards your finishing position or class records because not everyone gets the extra run. I guess you guys will have to go back and lower that record again!

let us know in advance next time you guys go there!!!

On the weekend I just did an Audi R8 day down at Phillip Island and we put the clock to a couple of laps and got a 1.50.0 and a 1.50.2 which I can tell you I found staggering in a stock prodution car on street tyres. Apparently the race dude they had there (Christian Murchison) had done a high 1.48 earlier in the week.

Now I reckon one of the factors for such a great time was the DSG gearbox - it sure was impressive to use around the track - you can even downshift midcorner without the car so much as flinching. Awesome stuff.

And yet scary to think in Top Gear the R35 was roughly 5s per lap around the test track faster than the R8.....

how can i get into one of these r8 track days man, id love to go down.

      Duncan's V37.......race car?

      By Duncan · Posted

      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.

      spot the stagea

      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...

      34 de+t conversion using s2 stagea automatic transmission, engine harness and ecu

      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.

      34 de+t conversion using s2 stagea automatic transmission, engine harness and ecu

      By albyz34gt · Posted

      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
