ah noooooooew.

We ran out of fuel!!! Ended up with a 1.04.9. Had a low 1.04 in it, but wasn't to be.

Huge challenge even to make the event. The old man and my brother put in a big effort.

In the weekends leading up to it we dropped a heap of weight, did heaps of maintenance to suspension bits, changed the diff (mine is broken, no time to fix), borrowing brake pads on Monday night (i was working in sydney tues-fri) and in the days before get a wheel alignment and new tyres (on Friday).

At a track I'd been too once before, with tyres I'd never run before (z222 285/35), with no ABS (borrowed diff was a non ABS unit) we ended up 4th in Club, so very close to 3rd.

Great result and congrats buddy especially with all the challenges . What's your car weighing in at now?

Micks car is a great car and a credit to him, particularly considering the rumour of the 7 figure sum that has been spent on it. Couple of things though. Micks car is in Pro-Am not open. http://ww

All competitors must use Advan tyres?? Surely not!

"Alternative materials are permitted for the Front Bar, Bonnet, Side Skirts, Rear Bar and Boot provided they follow the same shape as the original part.

Alternative materials are permitted for front and rear flares.

Localised modifications of OEM fenders to allow fitment of the control tyre.

OEM fenders must be of original material however flare extensions are permitted to cover control tyre.

The top 1/3 of the tyre must not protrude outside the guard/flare when the wheels are facing forwards.

The remainder of the vehicle body must remain as original from the manufacturer. (no wide body kits)"

In Pro class they changed the following for chassis

  1. Rear retention of the original chassis:

  2. Original floor pan and frame rails must be retained from the firewall to the forward most point of the rear wheel arch. Allowance for removal material for fitment of fuel or fluid tanks and associated fittings is permitted

So you have to retain the floor plan and rails except you don't....... I heard that this one was coming as one of the top Australian Teams that was on the podium last year had actually had cut the entire middle of the car out for the fuel cell and oil tanks.

Short notice, is this affecting you guys at all? I need to re read them again... Especially with the new interpretations.

Alternative materials are permitted however all bodies must follow the same shape and retain the original look and style of the vehicle. Does following the same shape mean keeping the original side skirts? Keeping the original front bar?

Front and rear bars may be modified to incorporate aero design. Front bar may not extend further than 150mm forward and rear bar no further than 100mm rearward than the vehicles bodywork. Interesting

Yes those early Evo were very light.

I think they quoted the wrong minimum weight for the R32 GTR. Nissan produced a number of N1 car with a curb weight of around 1400kg. Let me try to dig out some more info

Ahhh Wikipedia it is http://en.wikipedia.org/wiki/Nissan_Skyline_GT-R:

The Skyline GT-R 'N1' model, introduced on July 19, 1991, was designed for home-market N1 racing with a total of 228 units produced. The most notable change was in the engine, which was upgraded to the R32-N1 specification. The car was also lightened by the removal of the ABS, air conditioning, sound system, rear wiper, trunk carpet, and the use of light-weight headlights. No color options were available and all 'N1' cars were delivered with a thin layer of Crystal White paint. The result was a 30 kg weight savings for a curb weight of 1,400 kg.

Hey dan, this is correct but in the new rules state that the car must have been produced at least 500 units to comply, what do you think your car will weigh?

That's the one.

I'm extremely disappointed, but at the same understand why they have had to do it. If the vast majority of the field enter with cars that are not compliant to the rules, then the class either folds or the rules change to allow those cars to run.

It's stuffed me around to the tune of $3k in wheels (as I wanted to run 10.5 + 15 but wouldn't fit under the guards so bought wheels that could and in doing so decreased the chance of getting a 295 on there), if I was an Evo driver I'd probably have more of a say.

Basically to stay competitive I need to modify the guards now.

It's funny how the magical "500" number pop up. If it's good enough for the Japanese to accept the N1 for racing why isn't it good enough for time attack event :(

I suspect those Evo weight are not quite the mass produced version either. I suspect some bias here.

We will make it as low as possible and then add weight if we are under. Only WTAC requires minimum weight, the other events don't so I don't just build the car for that weight. It's not easy to get the GTR to below that any how but just in case. Not nice to see some unfairness of this magical 500 number. Does anyone know of any real reason for the "500"?

      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?

      By Duncan · Posted

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
