Drag Racing, Comparing different tracks around Australia

[vevapower]

Billet for sure.

Heathcote is always 2 - 3 mph more and on Steve's 146 run he did run a bigger tyre.

Also why is it that no one breaks records at WSID?

More than 5 people have now told me this.

Its funny I think of Kwinana like that, I always come to Heathcote and run faster (ET) than Kwinana even though the track prep is not as good and my car is down 20-30rwkw in the 70+% humidity Victorian air...

I just put it down to getting more runs = more practice.

I think it was run in 5th, so it would show less wouldn't it?

I'm not sure how Dave runs them all I know is that Bayswater dyno is a heartbreaker!

Pro drag racers rate it as the best track in Australia, and records confirm its the best.
Last year in one meet, 20 national drag racing records were set at the Nitro Champs at Sydney Dragway.

[vevapower]

Are so its all the non pros that make this claim?

[SpoolMan]

No idea who claims what, I have good friends who travel the ANDRA scene across Australia and Sydney is the place they love to race, theirs and the ANDRA records is the only info I can share.
From a street car perspective we like HPR because not having a cage isn't an issue.

[vevapower]

Willobank holds the most records.

[prasac]

tell me again how the WSID track isn't any good



you will find most guys go on a Wednesday night, the track isn't prepped or has a little prep, if some fast cars say they are going on a Wednesday they will prep the track. it's guys that don't race regularly, don't have the car sorted etc that have issues, we have done alot of Race 4 Real's and the car has been fine as we can make adjustments with the eBoost2 etc. last Wednesday was also cold, the track was dewy and unprepped. little to no quick cars to put warmth into the track.

go on a Test n Tune, Full Throttle Friday or when a big meet is on and the track is at it's best you will run super quick

[vevapower]

Yeah I know WSID can be really good at last years Test n Tune I dropped 0.4 of my previous PB track was like it had sandpaper on it.

My point is that I hear that other tracks can be quicker and i don't really understand it.

My mates dad runs a NA XY super sedan I think can't be sure. He's said things like at Heathcote he runs 147 mph but his PB at WSID was 144! Then you have the guys from Pac that seem to always run PB's at Willobank.

Also you have the guys saying Calder is always about 0.2 quicker on average.

Would be good to hear other peoples input on this.

[prasac]

it's not just track there is alot of variables that come into it, weather, car changes, altitude etc etc

Sydney has got many many records, don't blame the track

[ratter]

when I used to crew years ago and both Calder and Heathcote were being used and prepped properly, it was always considered that most cars would run about 2 tenths quicker at Calder and it was because of the RA, guys running against indexes would have to adjust their cars or times depending on what class they raced in

Nah in no way am I blaming the track (WSID) I'm just trying to get an understanding of how and why other tracks might be faster at times or generally.

Some healthy discussion would be great.

I just got a message from my mate Jason Grima and he said temp is the main factor when deciding on what track is quickest!

[SpoolMan]

Yes for sure especially boosted cars in the cold weather, we have seen 3/10ths drop with the yellow F6 from one meet to another.

Perhaps this discussion is better played out in the drag racing Forum area, leaving this thread for the ZF.

Yes I agree Spooly can we move it to there?

a couple degrees here and there for Pro Stock guys like him, it's important. we are intercooled, run E85 and have alot of things in our favour. we have raced in 8C nights and 38C days, was roughly about 1/10ths difference. our quickest pass to date was run on a 27C day

just seen Spooly's post, i will start a thread Matt

[prasac]

discussion on what is the quickest strip in the country.

i believe Sydney, Willowbank then Perth in that order just from guys i know that have raced there.

[SpoolMan]

This thread has been cut from another thread to discuss the difference between drag racing tracks in Australia.
Altitude, ET, MPH, Weather temp and humidity, start-line and anything else you can think of.

[vevapower]

Thanks Spooly!

Could be a great thread this well informative at least!

[Giant]

+ 1 for the Sydney Track Crew also a big thanks to Ray Treasure, if your after a sticky track try a Track Championship Day at WSID.

RA = Relativity Altitude and it plays a big part for NA Petrol cars, has a smaller effect on alcohol cars and reduced effects on intercooled turbo cars.

Humidity will effect both NA and Alcohol cars, less so on a boosted application.

As each track is at a different real altitude and subject to different weather conditions, each track will have its own benefits. The layout of WSID for example reduces the effects of crosswinds and tail winds compared to a open layout like Heathcote.

Depending on your power out and car setup a bit of wheel spin will help generate wheel speed and reduce the engine load / stop it bogging.

Which track is the closest to sea level?

Small world, he used to live on my street.

I would expect with WSID being the newest it would set the highest standard. Selfishly of course I'd like to think when I race there it's going to go faster, not slower, at another strip n

Ravenswood used to be, I believe Adelaide is now.

[T4ME]

That's what I thought even with the moderate to heavy WSW winds common on race day here I remember back when it was pretty full on racing(90s/early 2000) plenty of interstate guys looked forward to the trip over on comp meetings/4,6,Rotor Shootouts etc.

Now with a Doorslammer owner taking over AIR's meetings the prep is even better imo...he doesn't scrimp at all.

[data_mine]

Comments as an social drag racer, who does nothing but bolt on some tyres to prep the (circuit focused setup) car.

I've only raced at WSID and Heathcote. As other have mentioned, my MPH is higher at Heathcote, but my ET's are quicker (and more consistent) at WSID.

e.g. this years AFFNats, closest I got to my PB (12.427) was a high 12.5. but spent the whole two days doing mostly low 13's (i.e. way off). but at 112+MPH.

a Wednesday night at WSID will see me doing 12.5 after 12.5 after 12.5 at 108-109MPH.

[jd dad]

Don't know that I would place too much faith in Heathcotes timing system being 100 percent accurate. Sydney and the other major tracks and systems have to be certified to be able to claim records so pretty sure they would be right.

[347xt]

willobank is better because you cant smell the tip the hole time you are there like in sydney

[prasac]

small tyre PB's seem to be run in Sydney more than any other track. you need to remember the super quick car's run 33x17'' slicks.

i follow alot of the APSA guys, these are guys running small tyres, the majority of the APSA guys have run PB's in Sydney compared to Willowbank etc. the few guys i have seen that have gone to WA to race, have run similar times within 1/10th.

the smaller tracks are getting better, i have heard good reports from guys going quick in Portland and Benaraby, for now, i think since Ray Treasure came up to Sydney, i think it's the best track, followed very very very closely by Willowbank on the right day.

[nugget378]

Ive seen the same, mph reads high at heathcote by 3 to 4 mph.
