It doesn't really matter what's going around the track cause it's all entertaining :) Even the sound of an Alfa GTV climbing out of a corner with it's carby throat's wide open or the thump of the ol XD....... Sweet !

IMHO, these are race "CARS" ! Unlike those things that "look" like cars that race now days :P

I'm with ya mate!

I went to my first historics at Sandown last year, and it was a top experience. Sensory overload!

Light years difference in the cages and the way the suspension is set up...they spend scary amounts on shocks these days.

So Terry has fixed the ol RB20? Be good to see the cars out running around...is there a chance that both Sydney R31s will be coming down?

Ok so the cages are different but surely quality of cages these days cant make the car that much more ridgid.

Going by the smack that everyone is talking in here, u could put a 2000 onwards cage and shocks in a gtr and hose the gibson car.

somehow i dont think so...

You would hose it the Gibson car. Remember back then you had Yoko fighting Bridgestone fighting Dunlop. So tyre development was helping the cars. These days with control tyres you are not going to get the tyre development.

Imagine a GTR with stiffer chassis so they can tune the better shocks to hold the road better and get more out of tyres that are much better then what they ran on in the day (Assuming the tyre design is suitable for the car)

On top of that you now have turbo technology that would allow them to run higher boost without bearing failure (should the rules permit more boost) and at a minumum more effecient turbos and ECUs.

I think there would be a few things that would add up to meaning that if you built a Grp A GTR today with what current practices and technologies they would be quicker.

Think about it, they only have to be half a second per lap quicker to win by 20seconds in a typical race...thats a killing

...and do we know for sure about the 3 R31s? I will confirm this weekend if the Vic car is to be run. I cant see him running it if he hasnt given a shakedown at Calder.

Cheers Roy,

going by these comments and others in the thread it seems as though u could make a gtr these days with the same peak power because everything else would be so much better u could put non slick tyres on it and still be faster

Now that would be cool.

I think a lot of the GTRs getting around Vic have similar power to the Winfield car. Difference is in the fact that they still typically run performance street suspension, not competition suspension and the weights and chassis rigidity of the cars are not as good.

And no disrespect to the owners but i think they will all concede they are 1-2 seconds off what a professional driver would get out of the cars.

That all said there are GTRs doing 1:18-19s at Sandown on road rubber and full weight and 1:30 flat at Winton and 1:42s at PI. So they are BS quick considering

SK, they are nice pics, but you'd have to admit, there's nothing like seeing it in the flesh ;)

I've spent so much time just looking over this car, admiring the craftsmanship and attention to detail. And as good as it is from the top, the underside is just as amazing ( which I think you've seen from memory ? ). It's funny though, how many people rock up and say it's much smaller than they expected :rant:

2630GTS, you have to remember what this car was built for and what was available / allowed at the time. :no: I would LOVE to see what Fred Gibson & his crew would build with today's parts ( and a full Nissan factory budget ). Could you imagine his take on the R34 for an attack on Bathurst :yes:

Roy, I'll talk to Terry today and confirm the Sydney cars.

I heard that when a a V8 supercar is built the test how much twist the chassis has by using XX amount of force to make a 1 degree twist, after 12 months it is tested again and surpirsingly it takes something like 1/3 less force to make that 1 degree change.

Hence a 15-16 y/o care probably has a HEAP less rigidity.

im no expert on the situation, thats just what I was told by a guy who would know.

None the less I love the old Gibson GTRs and they will always be a favorite car to me.

I went to my first historics at Sandown last year, and it was a top experience. Sensory overload!

I used to go and watch them when they were cutting edge touring cars, not historics. And yeah, it was a spectacle.

Quite a sight to see a Volvo 240GT two wheeling around the esses at Surfers Paradise

Great to see an M3 take the GTR under brakes into Hungry Corner at Lakeside

A bit deflating to see the relatively underpowered but pretty HR31 get belted by Sierra RS500s. There was only ever a max (that I can recall 3 HR31s running - two Peter Jackson Racing, and Murray Carter as a privateer)

And a lesson in engineering superiority also to see the GTR absolutely trounce everything off the line and then pretty much control race pace. Fast, professional, everything they should be, but sadly never hit the mark for aural entertainment like a V8.

Are the Group-A GT-Rs like 1200kg? Or something like that. Under 1300kg's if I remember reading somewhere.

I'd have to go back a bit to remember, but I believe on introduction they were over 1300kg - engine equivalence factor put them in the same weight class as the destroked 4987cc Commodore. Then they were ballasted and de-boosted to nobble the advantage. I believe that come Bathurst 92 they were weighing 1500kg and suffering brake problems as a result.

Hmm, maybe my memory is playing tricks on me, but I don't remember Murray Carter ever driving an HR31. I thought it was a DR30? Chris Lambden (Not sure of spelling) had an HR31 in Beaurepaires (Spelling not getting any better, is it?) colours. He now is editor/owner/something important in Motorsport News fortnightly magazine/newspaper.

      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.
