If anyone attended the Oran Park open practice on the 25th Sept pls post your times and photos here.

There was a good showing of Nissan's at the track and some pretty respectable times were laid down. The best of the Nissans was in the 1.20's.

I have some in car video that will be on youtube later today.

I will post up link when ready.

Rgds,

Did you have any ideas on time Andrew?

The black S13 was me!

Was a great day, heaps of fun!

Started to come to grips with the car again after a few mods. I ended up doing a best of 1:20.06 timed with an XT lap timer however I know there is more in it just from watching the vid... definitely braking too early into the kink, turn 3, Sutton's and the last corner so plenty of room for improvement :P

Evil, I was behind Andrew at the 6:40 mark on the vid in my white S13, he slowed and went wide to let me through, but I stayed back and waited for another opportunity.

All three of us (Andrew, SRS13 and myself) managed to dip into the 1:20 lap time, which isn't too bad considering it was very dusty from the dust storms we had during the week. We all wanted a 1:19 but it didn't quite happen.

There were a couple of times we were fanging down the straight and then just at turn 1 a car would enter from the pits causing some severe holy crap moments!! Don't know what the guy releasing people from the pits was thinking sometimes! You're close to the limit and then you have to deal with a slow car entering on your line. After the first time it happened I was more wary but would've liked a less crowded day.

All in all, it was one of the best track days I've done. It's an awesome track OPGP and I shared it with some mates, met some cool people and totally loved it.

Can someone please build another Oran Park GP real soon??

I know s13devciat has done a 1.20.2 on the GP on official timing, and thats hooting, just didnt look as quick in that youtube vid? (no disrepsect, Im 7 seconds slower anyway!!!)

yeah I noticed that...what were the pit guys thinking? you guys would have eben around 200kms, back off for the kink, and they still let someone go!

I would have shat myself too!! lol

The 1:20.XX laps were not captured on the vid. I know my quickest lap of the day, 1:20.65 was in the 3rd session as was John's lap of 1:20.06 in the black S13.

The youtube vid was 4th session. I think Andrew just uploaded the video with the most action going on!

Last session of the day Andrew managed to punch in a 1:20.80. We were all using the XT lap timer, I know it's not official Natsoft timing but I've compared the two on a previous supersprints at OPGP and they were within .05 of a second of each other, so pretty accurate.

Wouldn't mind attending one more supersprint or event with official timing just for the record before it closes! Lol!

I know Circuit Club has a day coming up at OPGP 28/11/09, hoping it will have official timing.

Everyone seems to have the same gripe. Personally i think you can see fairly early on the straight whether someone is pulling out and brake/keep left without browning your pants. You're high enough up in a street car that you can look down at the staging area as you crest the hill on the straight and see whether anyone is in the process of driving out rather than waiting until you see them pop out past the wall while you are fully commited.

In defence of the pit guys, some people go out pretty hot, some dawdle, some don't go straight away when they are waved out. On a busy day it's the difference between coming out in a gap and coming out in traffic.

I agree on the xt racing timers accuracy at OP. Mine is pretty spot on at OP and about .2 faster at WP

When your barelling down the straight at over 200km with 2-4 cars around you, the last thing I am thinking of doing is looking away from the circuit over a brick wall to check if someone is pulling out. I am mindful of where I am going and what the other cars around me are doing.

Whilst we all have a responsibility at the track to drive and act safe, I don't believe drivers who are travelling down the straight at those speeds should have to contend with a person pulling out onto the track at 50kmh going onto the driving line. The marshall should be watching and making a decision as to when the best time is to let the car out and the person entering the track should be watching what the other cars are doing and take extra care and caution.

I know the marshalls don't always get it right but some of the calls were absolutely dangerous and possibly reckless. I was with Mark when the guy pulled out in front of us and I really did sh!t myself. I honestly thought someone was going to hit him.

Anyway, no real harm was done and it was a great day. Cant wait to do it again!

The faster times came later in the day, this was the third session of the day. The boy's turned it up after lunch.

In defence of the pit marshall, when you are standing at the far end of the straight where car are entering from the pit, it is impossible to see the begining of the straight and therefore he cannot see what is coming out of the last turn.

By the time he releases someone into (clear) track cars sneak up on the pit exit at close to 200kms.

I think he was doing his best. I think that is the reason for the small tower half way down the straight, but it is impossible to manage with one person.

I didn't find it to much of a hassle, just had to be on your game.

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s

      It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
