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.

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.

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.

Thanks Spooly!

Could be a great thread this well informative at least!

+ 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?

Ravenswood used to be, I believe Adelaide is now.

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.

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.

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.

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.

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

[dieseltrain79]

Maybe Heathcote has incorrect settings on their mph terminals , or setup incorrectly ?

[ratter]

Heathcote used to host Andra racing so the track would have had to been set up 100% correctly, no idea about what upkeep has gone on for a long time though know to how accurate things are.

Heathcote may take MPH reading further after you have crossed the line, so MPH reading will be higher or their timing equipment is not as accurate, who knows.

[T4ME]

Downhill lol.

[naughts]

I have run at Heathcote and Calder... for me, Best et at Calder was a 10.91. Best at Heathcote is a 11.03. Calder was on 235 M/t Radials, street E/t's. at Heathcote I run a 8 inch slick because with the 235 E/t radial I don't always hook up 100%.
For me, calder1 tenth quicker.... And, same MPH at both..

[greencapri408]

I used to et 9.03 to 9.1 at calder
9.1 to 9.2 heathcote
Mph was 153 both tracks

[Giant]

I am thinking the extra MPH at heatcote might be created from the lack of track prep and the extra wheel speed created via the lack of grip............

The door slammers obvious have the track prepped to their standards as they always put on a good slamfest at heatcote.
