just out of curiosity. im no mechano. it could easely be a stupid question.

what would be a faster car around the track. our v8 super cars or a jgtc GTR?

why? and by how much?

i know the 32 destroyed the competition back then :thumbsup: . but what about now?

have they both raced on the same curcit? what were the times?

different rules, difference style of racing.

supergt teams have 2 drivers, and both drivers must drive during a race. during pit stop only one action can be performed at one time.

so

-driver exit the car

-new driver enters the car

-fuel the car

-change the tyres

so u can not change the tyres untill the car is complete fuel, normal pit stop times for supergt cars in the 500class is around 30seconds.

also supergt have alot of aero-dynamics

different classes with different rules

i don't know the specifics but you can't be sure that they all have the same rules to abide by, they can't possibly be compared in their highly modified yet merticulously restricted to regulations trim

its like comparing apples and oranges

Some mag i was reading a few years ago, think it was speed, said toyota tested the supras at PI, and they were about 10sec a lap faster than the taxi's

I remember reading that exact same mag, it was definately SPEED. I think it was in 2005. They had a special on an Aussie driver and in the article they stated the JGTC supra was 10 sec faster per lap on the phillip island circuit during testing. So yes I think its safe to say they are significantly faster BUT the V8 supercars competition is a very different typre of racing - there differenent regs to be adhered to.

Sorry but I would want to see a lap sheet from a timing system to believe the supergt cars are 10 sec quicker around phillip island

super car has 100+ hp more

supergt weighs less, has much better aero

but now way is there a 10 sec difference. 2sec from Shanghai sounds more like it.

Well one of closest thing we have to Super GT cars here is the Sports Sedans. On some circuits some of the cars lap can lap quicker than the V8s, and on other cars the V8s still hold the record for sedan lap times. There is only a couple of seconds tops in it though. I suspect you would probably find a similar story if the Jap cars raced a V8 supercar.

Otherwise all you can do really is guess.

I actually met James Courtney last year and actually asked him about it, he used to race supras in jgtc (not 100% on this but think he also won an award for being the fastest overall driver in one of the seasons??), but races a ford V8 supercar now for jeld wen motorsport, came second this year in bathurst i'm pretty sure?

anyway, from what he said, they tested the jgtc cars at qld raceway once in the off season, and they were about 10 sec a lap quicker than the v8 supercar times. so they are pretty quick, but it's not really a fair comparison, they are completely different cars, built to completely different rules and regs.

Even the V8's now are pretty quick, if you have a look at the current V8 times around bathurst etc. you'll prob find that they are quicker than the group A r32 gtr's.. race car technology has gotten a lot better since the early 90's i guess.

Still would be great to see more makes fighting it out, instead of just fords and holdens..

just my 2c!

Sure cage design has improved, data acquisition helped the cars lap quicker over the race distance. But most of the gains in lap time has been purely because of tyres.

Japanese GT cars are not even in compliance with the FIA GT cars. Last time they did that they got beaten by the Europeans and Americans with thwir Mclaren F1, Corvettes etc etc (in various classes) So the Japanese have their own class of GT cars which means they are not as readily able to race against the Prodrive Astons etc etc which is a real shame as it would be great to see them running at Le Mans against the Vettes etc.

It makes me giggle when ppl wrongly say that local Touring Car regs were changed to ban the GTR, when the truth is a few years later the Japanese turned their backs on the FIA homologated GT cars as they were gettign beaten by the Europeans. But to their credit, they tailor their class to suit their local market, ppl dont want to see 350Z getting beaten by 7.0L pushrod Vettes ;)

back to 10 seconds faster around Phillip Island.....

just looking at PI Track records http://www.phillipislandcircuit.com.au/upl...gust%202007.pdf

Supertaxis 1.33

If a GT500 car is 10 secs quicker that makes it 1.23, and faster than:

F4000 (and outright) 1.24

Formula 3 1.27

Sports Sedan (fastest tourng car) 1.31

Superkarts (lunatics) 1.32

Formula 5000 1.31

LOL..ok stay with me here...

GP bikes do 1:29s at PI , V8 Supercars do 1:33s as Duncan pointed out. So thats about 4 seconds slower over a lap of fast flowing track.

At Sepang the best quali time for a JGTC in 2006 was 2:00.6, a GP bike will do a 2:01.3. So about 1 second quicker then a GP bike at a high speed track

At Twin Ring Motegi the GP bikes do 1:45.8s, where as in 2005 the JGTC cars were doing 1:46s, and in 2006 the JGTC cars did high 1:44s/low 1;45s. So at a more involved track the GP bikes are as quick

So if a GP bike is doing 1:29s at PI then its not a hige leap to say that at best a JGTC car may be 2 seconds quicker then a GP bike, more like within a second.

So, that means a V8 Supercar would be around 4-5 seconds slower then a JGTC, no way the JGTC car will be 10seconds quicker...NO WAY

yeah i was just putting it out there i wouldnt trust a magazine lol

I do wish the taxis where modded to the same level tho and had to use an engine from something they are producing.

Ie holden with their new 7.0ltr v8 and ford with their 4.0 inline six turbo

Also dont know if its 100% true but holden shouldnt be able to run ford parts, ie the diff :S

    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
