Well the NSW State Champs are on at Eastern Creek this weekend - but the twist is that it is the first race meet on the new, "north" circuit.

$9M of taxpayer funding later, the ARDC can now hire out the track in 2 halves. This weekend's state champs are on the short track but the same price as when the full track used to be used.

The quickest cars are doing the lap in about 1min which is around 2/3 the length of the old track, it has also removed turns 4,5,6,7,8 and changed 9 to a kink.

Results are here: http://www.natsoft.com.au/cgi-bin/results.cgi?23/10/2011.ECNT

:down: from me.....did anyne race there today, and what did they think?

Gaytube, dunno how to embed videos.

I don't agree with the entry cost being the same for half the track although standing at the new turn 4 for 4hrs today it is quite an exciting little section that turns the whole north circuit layout into more of a horsepower track than EC already was. Very bumpy on the entry to turn 4, take too much curb and it will bounce the car around and make it difficult to get the right line into turn 5 which then effects top end speed at (the new) turn 6 kink.

anyone found onboard video of a lap?

I was hoping there would be some by now, or feedback from someone who has run the new track

.....it is quite an exciting little section that turns the whole north circuit layout into more of a horsepower track than EC already was. Very bumpy on the entry to turn 4, take too much curb and it will bounce the car around and make it difficult to get the right line into turn 5 which then effects top end speed at (the new) turn 6 kink.

That's exactly how I see it without having tried it yet. It increases the worst thing about the track (dragstrip/power track) while removing some of the challenging corners. In a soft car like mine I guess the new turn 4/5/6 complex will be easy to cut, we approach turn 4 in high 3rd or low 4th gear so we aren't as fast or as stiffly sprung as the radicals in the video. I bet the IPRA guys were cutting like crazy.

The track hasn't been ruined, its just gives another layout option (just like Oran Park had).

Well, to me, Oran Park South was one of the few track that was not really worth running on. I turned down plenty of chance to run there, the OP GP circuit was a totally different matter, its the best track I've run on.

And it at least had the challenges of suttons and the flip flop, EC North has nothing like that (turn 1 is ho-hum once you work out how fast to take it, 2 is just slow, 10/11/12 is the only fun remaining)

could be worse - look at QR... their most common short track leaves just 3 proper corners. Mind you, they only have 6 to start with. The short track sections are nonsence flip-floppy things through spoon drains.

      Mistakes were made, my R34 Story

      In a few years from now, you'll regret that. It'll eat away at you, knowing the truth of the ugly hiding beneath the beautiful exterior... 😛

      I don't think the G2 profile is particularly dangerous for the engine per se, more just are you actually ok with the turbo lag trade-offs? If the answer is yes then go for it. I personally don't think I'd be ok with it because I spend so much time at lower RPMs and I really enjoy the feeling of being able to stay in 5th gear on the highway and just roll into the throttle to get boost. Or staying in 3rd gear on "gentle canyon cruises" without feeling the turbo lag too badly. The 525 pump should be able to run flat out on factory lines but I would bet the pressure drop from pump to regulator is quite impressive. I don't know how much it would be exactly but I've seen figures like 30 psi thrown around.

      It's interesting seeing everyone talk about what level of risk they are happy to tolerate.  Building a GTR always has a level of risk, you could be that lucky guy that drops 20k on the engine build alone and still has the thing go pop on the dyno. Life is fun like that.  The way I see it, the thing is a toy to be enjoyed. I'd be happy to turn up the power on stock motor and limit the risk with sensible tuning and engine protection. If it still goes pop, it is what it is. The car isn't a daily driver so it can happily sit while a plan is made to sort it out.  Given this thing will be a street car only, I really feel it's worth the (relatively small if managed well) risk to turn the power up to around 350KW on e85.  I don't think anyone getting into the skyline game now is doing it out of logic. Surely it is a purely emotional decision so I'm not sure how important it is to think about the engine build logically. The heart wants what it wants.  @joshuaho96 little note for Josh, I run my 525 pump flat out all the time and through the factory lines without any issues. (excluding the melting connectors, that's sorted now. we'll pretend it never happened lol)

      But the Nexus S3 is very expensive and won't be as purpose-built for the application as a separate electronic boost controller :^) More seriously my pet issue here would be that the Walbro 525 running at 100% duty cycle is going to require more FPR than the stock setup can handle. I'm also pretty sure from what I've seen elsewhere you might want to slow down the pump regardless unless you're going to come up with some way of upsizing the fuel lines coming from the fuel tank. Factory 8mm fuel line doesn't actually flow very much if you want to keep pressure drop down between the fuel pump outlet and FPR. If you really want to "keep it simple" I would run only as much pump as you need and source a fuel pump controller to slow down the pump in the vain hope of being able to run stock-style FPRs which are pretty dinky. Or just use the HICAS lines and it should be mostly fine. OP should also really think hard about what profile they'd want out of the turbo. My pet choice here would be the G1 profile rather than anything higher power but YMMV. I already think ~stock turbo lag is pretty bad so I don't want to make it worse. In "gentle canyon cruising" I found that I spent a lot of time around 4-4.5k RPM. I also recommend DIYing labor if you're detail-oriented enough. Costs are high for labor + if you do it yourself you can be your own quality control.

      GTSBoy is again on the money. My actual advice? Sell the car. (really). For what it's worth as is, you can sidegrade into something much better. If you care about function then this is the actual move. If you want a Skyline to perform, set aside about $100K to do it. This is NOT a typo. You will see right away these are two very different mindsets. Realistically we're talking full restomod for any Skyline still kicking around. Have an honest think about which one you are.. and what you want to do, and how much you want to invest in this (with no return).
