COTF shares an almost identical weight distribution to previous cars.

The old diffs were heavy and by the time you added drive shafts, spool center, crown wheel and pinion, diff bracing, watts link , bearing carriers, brakes etc to them the weight crept up.

The tank was also behind the rear axle. A full fuel safe sprint cell with swirl pot reserve and pumps was around 130kg.

The new transaxle is lighter than the fuel system and diff of old combined.

The COTF fuel tank is slightly heavier than the Hollinger which was In roughly the same position (further forward obviously but I between the axle none the less)

The chassis are not that dissimilar in terms of torsional rigidity and behaviour.

Regardless of what people think the floor pans of last years car right back to VX have very little incommon with the road car.

Nobody mentioning that Gary Rogers will be running two Volvos next year? Good to see the series kicking a few goals re manfacturers. Next test will be to get some satellite series going and then hav

Are the DVS cars still a relivent stepping stone to the main game with the new cars? I notice Luff and Purcat are in Porsche Cup this year, and I remember Skaife saying this years cars drove more like Porsche Cup cars

Yes still relevant - but obviously not as much as last year. The COTF is, fundamentally, a different beast to setup & drive than last years cars. One result will be that the co-driver/internationals (if they are going to the Gold Coast this year) wont suck as much in comparison to the regulars as the cars are

A: Easier to drive

B: More like other categories in the way they drive.

It is for GTR and skyline owners.

I've owned over 15 of them in 10 years.......

When I locked up tonight there was 14 cars in my workshop, 8 of them are Skylines, 7 of those are seriously high end preped Motorsport cars.

.....

But how many could do 1000 racing Kms around bathurst? The engineering on Gibsons cars was amazing. It may be old now, but doesnt make it bad. Group a also gave some creative interpretation of rules, which was interesting, and something you don't get in the current series, for better or worse.

You can still see the grp a cars, and get closer than you ever would have been able to for the fans. Go to http://www.heritagetouringcars.com.au/

On topic, I really looking forward to seeing the v8s this weekend. Hopefully the new marques can improve, and the Mercs have a more consistent meet.

Honestly there is 3 I'd send up there as is and one more that would be close.

There is harder places on the tour than Bathurst. Clipsal was one of them. Chaos canyon on surfers is obviously another.

What GMS did with the GTR will always be admired. They took a nugget of a car and made it great, no doubt.

I'm betting there will be a win this year for Scotty mcglauclan. GRM have a pair of good cars this year and Scott has a lot of COTF miles. On one of his better known circuits I think he will come out on top.

quiet thread is quiet.

Couple of good races today, looks like some of the nissans are set up really soft in the front end- searching for fnt end grip maybe?

What happened to the Merc? Did it pop an engine today? I saw lots of smoke on the screen, I did wonder if he over rev'd it coming into T1, because it did sound tough right before the smoke poured out.

Was right about him getting a win but so early was surprising.

Even though 6 faster cars were relegated to the back helped his cause its good to see.

Hopefully he'll back it up. Great for Rodgers to finally get a win on the board too. Caruso was a bit of a flop and captain crash spent more time running into things than racing.

From what I understand ECU base timing was 7 or 8 deg and the crank sensor had been adjusted to give the 6 deg required base timing.

Timing light would have displayed 6 deg which is why there was no performace gains but the ecu has its trigger angles locked and they had 7 or something as base.

Chances are the engines have all been like this since they left the engine shop (they all use the same engine shop bare the Kelly's) Kelly's engines may have been at the same shop prior to Melbourne though.

There would have been no data available to V8 supercars from previous rounds so they could only infringe the last race.

When I installed the KRE built aurora engine in my VY we used a timing light and adjusted the crack sensor to get 6degrees base. Never even looked at what the ecu had as base.

There is actually very little you can do with the controlled ECU as far as ignition mapping goes. You have maximum timing numbers and the engines take those numbers very very easily. So its a case of throttle open maximum allowed timing and trim the fuel to suit done.

What is the go with Moffat? Is he lucked upon some good results or is the guy actually reasonably talented and starting to find some form?

I can't stand Moffat.

There is something about the guy that irritates me. He has had some shining moments for sure.

some very good racing this weekend. certainly showed why it deserves it's place at the top of australian motorsport. plenty of close racing, with a bit of panel rubbing. as far as viewing goes, it really does make f1 look pretty boring, where the cars being within a few metres of each other only really happens on behind a safety car

120L of fuel in the cell. I know the aurora engines the fast holden teams have use on average .9L/km. Kelly's claim they having fuel consumption issues so wouldn't surprise me if they are using 1.2L/km. plus the formation lap would have them out of fuel buy the end.

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

      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.

      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.
