- he 1997 Australian Touring Car Championship was a CAMS sanctioned Australian motor racing title open to 5.0 Litre Touring Cars complying with Group 3A regulations.
The championship, which was the 38th Australian Touring Car Championship, began on 15 March at Calder Park Raceway and ended on 3 August at Oran Park Raceway after 10 rounds.
Here is round 1 from Calder Park - กีฬา
Odd to hear the great Barry Sheene commentating on car racing!
He used to get criticised about this all the time. It was the few years he spent racing in the BTCC that gave him the expertise.
Could you upload races from ANDRA (Australian National Drag Racing Association) from the 2000 season? I would like to see it.
esses carros não tem a velocidade de 1 F1, + são muitos rápidos!
What was the acceleration of these cars from 0- 100 kph and 0-200 kph ?
What is the stopping distance with the brakes for these cars, for example what is 200 - 0 kph and 100 -0 kph ?
0-100km/hr depends how much traction off the start bud. I'd say on a good launch would get to 100km/hr 2nd gear in less than 5 seconds easy. No doubt about it. They'd probably get to 400m within 11-10 seconds easy. Braking distances and times no idea but they'd definitely stop 3-4 times better than they go in a straight line and go through a turn like they're on rails
@@Nick-wh4jt I think a 1997 V8 Supercar by the time it was ready for Bathurst in 1997, if you were to take it to a dragway, could do 0 -100 kph in 4.083 seconds and 100 to 200kph in 6.41 seconds.
So that is 0 -200 kph in 10.493 seconds and I would say it would get to a 1/4 mile, 1 second later and the speed would increase by 9.8 kph.
So that is 11.493 seconds (around 11.5) at a speed of 209.8 kph for 1/4 mile maybe.
I will go into more detail below how I have estimated this below.
@@Nick-wh4jt Performance of V8 Supercars is not very easy to find, but I think the best way to work it out is through the onboard telemetry during the races.
Luckily I purchased a Motor Oct 1992 mag a couple of years ago that had Ford Sierra and Dick Johnson 1992 Falcon EB in it.
In that mag it was estimated that Dick Johnson Falcon could do 0 -100kph in 4.25 secs, 0 - 160kph in 7.71 secs and 0 -200 kph in 11.26 secs.
This was with 394 kW @ 7500 rpm (nearly 530 hp) and 1300 kg minimum weight.
They didn’t give 1/4 mile time, but assuming it may do a 1/4 mile in 11.9 seconds, 0.64 seconds after 200kph, averaging 9.2 kph per sec for that last part, then that would mean it may be capable of 11.9 sec at 205.9kph .
You can see onboard telemetry (not best quality) about 41:30 into “1992 Nissan Mobil 500 Wellington - Full Race” You Tube Video , showing acceleration down Jervois Quay straight.
Based on mag 7.01 seconds from 100 to 200 kph seems about right for this race car, so I will use this for a starting point with 1990’s V8 Supercars acceleration.
@@Nick-wh4jtNow to working out acceleration of 1997 V8 Supercar.
Based on Dick Johnson Falcon with 530 hp and 1300 kg in Oct 1992.
I am going to make an assumption during 1990’s that a V8 Supercar is usually 10 hp more powerful each year when it goes to Bathurst. There are some exception which I will note.
Assuming 10 hp additional lowers 100 to 200 kph time by 0.1 seconds.
Now in 1993 the horsepower rose to 550 hp at Bathurst and still weighing 1300kg, so it was a 20 hp increase over the previous year.
This may mean that a 1993 V8 Supercar may do 100 to 200 kph in 6.81 seconds.
In 1994 horsepower was now 560hp at Bathurst and still weighing 1300kg, so the 100 to 200 kph now 6.71 seconds.
In 1995 I think the horsepower was 20 more at 580hp, but the weight now increased to 1350kg minimum.
When you work out the power to weight ratio for 1995 Bathurst V8 Car, it is no better than in 1994.
However I would say due to some adjustment in the engine technology it may have been 0.1 seconds quicker, so 100 to 200 kph for 1995 V8 Supercar is now 6.61 seconds.
In 1996 horsepower increased to 590 hp for Bathurst , so 100 to 200 kph now 6.51 seconds.
After 5 minutes into this video “1996 Australian Touring Car Championship | Round 9 (Mallala) - Race 3”.
I measured 96kph to 181 kph in 5 seconds down a short straight, so I think 6.51 sounds about right.
1997, horsepower now increased to 600 hp, so that is another 10 hp and that is how I have got 100 to 200 kph in 6.41 for Bathurst in 1997.
This is quick for a Race Car that is 600 hp and 1350 kg minimum weight, I wonder what makes it quicker than it should be for it's power to weight ratio.
The following 1998 year with Glenn Seton onboard telemetry 14:40 into Race 23 - Calder Park [Full Race - SuperArchive] | 1998 Australian Touring Car Championship, I measured 101 kph to 197 kph in 6 seconds , so that may mean about 6.3 seconds for 100 to 200 kph in 1998.
Now for 0 to 100 kph time.
From what I mentioned before In 1992 Dick’s Falcon estimated to do 0 to 100 kph in 4.25 seconds.
I seem to recall that in 2000, a V8 Supercar could do 100 to 200 kph in 4 seconds flat, this is 0.25 seconds quicker.
To work out acceleration in 1997 :
In 1992 it was 7.01 sec and 1997 6.41 sec for 100 to 200 kph.
We can see from this, that there are 6 times speed has increased by 0.1 seconds for 100 to 200 kph.
To get to the year 2000, I will assume it increases by 0.1 seconds each year, so in year 2000 it is now 6.11 seconds from 100 to 200 kph.
So , for 0 to 100 kph, why not split the 0.25 seconds difference between 1992 and 2000 into 9 increments.
So in 1997 , 0 to 100 kph = 3/9 * 0.25 = 0.083 seconds above 4 seconds .
This is how I got 0 to 100 kph in 4.083 seconds for a 1997 V8 Supercar ready for Bathurst.
The calder park car in this video , is a bit closer to 1996 Bathurst car in terms of performance I would say, as it was in March 1997.
@@Nick-wh4jt The braking for a 1997 V8 Supercar is a tricky one to work out.
However , I tried to work it out from TH-cam video Race 31 - Bathurst 1000 [Full Race - SuperArchive] | 1997 Australian Touring Car Championship.
21 minutes 30 into this video I have tried to work out braking on John Bowes Falcon at 1/4 video speed.
It takes 1 second to brake from 240 kph down to what looks like 200kph, but I think is really 198 kph as it is between the time from 200 kph to 196 kph.
One thing I have observed when looking at braking is that the average speed is generally 42% between initial and final speed.
So in this case 240 kph at inital start and 198 kph after 1 second
That is a drop of 42 kph speed
42% of 42 = 17.64 kph
Add 17.64 kph to 198 kph = 215.64 kph average speed during this second of braking.
To convert to m braking, that is 215.64 / 3.6 = 59.9 m
One trend I have noticed about braking is that , say for example if you brake from twice the speed, say from 200 kph compared to 100 kph to a stop, it follows a ratio squared formula for calculating distance.
So at 200 kph it takes 2^2 = 4 times the distance to brake , than it does from 100 kph to a stop.
Now we can work out ratio of 240 kph to 198 kph and square it.
240 / 198) ^ 2 = 1.46924
The 240 kph to 198kph is the 0.46924 part of this ratio.
The distance for this braking from before is 59.9 m from 240 kph to 198 kph.
We can work out braking distance from 198 kph to complete stop
with 59.9 / 0.46924 = 127.6538 m braking from 198 kph to 0 kph
Now we can finally work out 200 kph to 0 kph and 100 kph to 0 kph braking
For 200 kph to 0
(200 / 198) ^2 = 1.0203
So this gives 1.0203 * 127.6538
= 130.2457 m distance to brake from 200 kph to a complete stop
For 100 kph to 0
We just divide braking from 200 kph (130.2457 m) by 4
= 32.5614 m or 106 ft 10 inches distance to brake from 100 kph to a complete stop
I think this seems about correct for a V8 Supercar in 1997.
I will see sometime how todays V8 Supercar compares to this braking.
One thing I have noticed about those brakes in 1997, is that they tend to squeal a bit when they are not quite up to temperature.
You can notice this in the HRT Car with Greg Murphy about 13 and a half minutes into that 1997 Bathurst video.
Can you do 1997 Australian touring car championship round 2 please
been year wen V8 Supercars race at Colder Park
