hmmm... graphed speed and lateral G from the 180 on Thursday and Aristo yesterday:

(lateral G x50 to get it to show up on the graph, so 50 is 1G. Peak for both cars is 1.2G

post-15659-0-06614800-1306113290_thumb.jpg

It wasn't the fastest lap int he 180SX - the iPhone didn't want to stay on the windscreen inthe 180, so I've only got data from the 1st session. This lap was a 60.5.

The automatic Aristo looses out in accelleration, but it looks like it was at least a match for the 180 in Eastern Loop and the last turn, if not a touch faster... Caught the 180 a bit under the bridge too. I suspect I lifted on that lap in the 180, or it got a bit sideways and scrubbed the speed off.

Aristo felt much easier to drive through Carousell, under the bridge and through the kink. Carousell's double apexer, the Aristo just goes where you want it to, no fuss at all. The 180 is always puts up a fight to get it back into the second apex. In the fast corners under the bridge and the kink, the 180 is pretty nervous on the bumps. Aristo walked over them with no fuss at all. Might be interesting with a bit more boost in the Aristo and maybe without the heavy electric seats! hehe

Hey, what app are you using to produce these graphs? I think you were using an iPhone?

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

very interesting. it looks like the 180 gets it's power down very well or just has a more punch set-up (I guess the manual vs auto would help too out of corners) as it gets a big speed advantage out of corners which it then maintains up through the gears. the aristo doesn't seem to give much away though in outright top speed and I guess peak G is not too surprising given both on the same tyres. it's interesting sometimes how quick a near standard car can go. makes you wonder how many of the mods we do are sending us backwards not fowards. there is a lot to be said for small improvements on factory engineering not wholesale changes. good steering too. :)

nice vid mate! nice driving too. That blue datto(?) sure had some grunt in a straight line. your thing looked great underbrakes and well balanced through the 3rd gear stuff but he had some serious tow down those straights and quicker stuff but then it looked like he ran out of tyre grip (or maybe concentration) towards then end and couldn't keep you behind anymore. looks like you picked up a bit of pace once past him too. car sounds great and looked nicely set-up too. well done. :)

You're right on both counts - its getting power down better with the FZ201 than it did with either the R888 or the Kumho slicks, And it's a pretty punchy setup - not hugely powerful, but good strong midrange

got to say I'm a bit surprised the big Aristo can get the same lateral G from those tyres despite 300kg more weight to lug around. But I don't think I was driving the 180 particularly hard enough on that run though. Let's see what I can get out of it this weekend...

yeah well you did already say you weren't 100% feeling at home in the 180 after half a year out of it. still very impressive stuff for the aristo, like you said lots more weight, but with softer set-up, more body roll etc it probably hangs on pretty well. and I'm guessing the big 2J has similar power to the 180? around 280hp atw? I imagine with a manual box it would get close to hanging with the 180 out of corners too.

makes me wonder sometimes why we bother with all the stuff we do to cars which makes the NVH through the roof, makes them stiff as buggery etc. makes them look more impressive to drive I guess!! lol.

Mark, thanks for posting. You're absolutely flying! S13 represent :)

Are you taking turn two and nine in 3rd gear? Is that to make the throttle control easier on corner exit? Have you found it faster than doing them in 2nd?

Cheers mate. S13's rule! Spot on with the gears. I never use anything lower than 3rd gear. Same at Wakefield too.

The car has good low down response thanks to the small disco turbo, it is faster using 3rd gear for me.

4.3 ratio diff helps

that's seriously stripped out Mark. very nice time!

what diff have you got? hard to really say in the vid but it sounds a little loose/open out of a couple of corners?

Thanks Harry! It's not too stripped, still lots to go. It weighs 1082kg without me in it. It sounds loud/good (I think) due to the side exhaust I'm running.

You're correct with the diff, nice pick up! Stock viscous lsd. It's starting to open wheel and costing me a little time on exit of corners.

I need to shim it and get better drive/power down. Only recently has it started to loosen up.

I set a PB in the session after that vid with a 1:44.19, finding a further 2 tenths of a second from driving better.

It's amazing when you think you found the limit, then you go abit quicker. I hope to go a little quicker next time so maybe 1:43's are on the cards next time.

Thanks Ben. Much improvement needed but I was happy for an initial test. Was great to be at a familiar track which made me feel more comfortable in the car, and gave me the chance to just concentrate on getting to know it. It was very well behaved, and once we can sort some of the understeer in the slow speed stuff it should be even better.

The bird made things interesting. I spotted it and backed off momentarily, made the heart skip a beat!

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

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

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

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
