Hello everyone,

Just putting the word out :- there is a new form of motor sport starting close to Adelaide in the near future, with a track currently being built at Dutton aprox 85 km from the cbd . If you haven't heard of Dirt circuit, it is the cheapest form of organised motor sport in S.A and also one of the largest with over 300 cars competeing. Dirtcircuit is a truly unique sport which combines elements from many motor sports :- the sideways action of drift, speedway & rally, the straight line speed of the drags and the driving techniques of circuit racing. There are currently 9 specially constructed dirt circuit tracks in regonal South Australia that range in length from 700m to 1000m. Features of the tracks include chicanes, hairpins, sweepers, long and short straights ect... . Track layouts allow most cars to hit top speeds of between 140-200 kph. Tracks are constructed of clay, limestone or an oil impregnated surface. . Racing is run with up to 10 cars competing in 6 lap sprint races, in both directions. Every driver participates in 5 races per meeting including a 10 lap allcomers race. In all classes there is a aprox 30+ races per meeting. Due to the racing format a car can have two drivers, which halves the cost of racing if you build a car with a mate. Kids as young as 10 can drive in restricted childerens races.

The classes are as follows :-

Standard class :- HQ shape holdens, early falcons up to 202 ci. No mods allowed.

New standard class :- VN -VT and equivelant falcons. No mods allowed ( Cars can be built for $1000 or less in this class )

Street stock :- Carby cars up to 265 ci, valiants, falcons, commodores ect.. . Mods:- 350 cfm carbies, aftermarket cams and extractors, original engine position and no fibre glass panels.

Modified saloon :- Anything goes in this class :- Steel bodied cars , space frames, fibre glass bodys, standard, mid or rear mounted engines, turbos, blowers, injection, any vehicle engine combo eg :- 400 ci chev mid mounted in a Datsun 180 B ( don't laugh there are a few v8 powerded datsuns out there ). Cars in this class range from cheap wrecking yard racers to 600+ hp ,supercharged, spaced framed sedans and yes the 100 hp cars do occasionally battle it out in the same race with the 600hp cars. This class caters for all budgets again a car could bee built for less than $1000.

Open wheelers :- Again anything goes. No restrictions on engines, running gear ect.. . This class allows you to build a unique chassis / race car of your own design. Many cars run mid mounted V8s, auto transmissions, 9" diff or irs. There are now alot of turbo jap cars being built to give the v8's a run for thier money. These cars normally weigh between 600kg - 1000kg, so even with a standard engine you can achieve a great power to weight ratio. Its not unheard of for people to build cars exceeding a v8 supercar power to weight ratio for much less than $10k.

Here the best part, subs for the year costs only $20-00 per driver, there is a $10 nomination fee for each race meeting and we don't charge an arm or a leg to spectate :- Adults entery fee is only $5-00 at the gate . There will be a total of nine race meetings a year at the new club, but if you have the time you could race every weekend at any of the other 9 tracks. Each year there are 2 rounds of the State championships which is rotated between clubs.

If any one in the Metro area is interested in racing dirt circuit, we can volunteer experienced drivers to help you build a car and even source cheap materials and parts to get you out on the track. If you want any other information please call Matt on 0447739992 or email [email protected] . There will be a free open day at the track in July for all those that are interested. We should have a good mixture of all types of cars racing and on display. I will put another post up when I have a firm date for the open day.

Cheers Matt Stirling

That looks like a shite load of fun!

hrmm... new stock you say.... it says no mods are allowed - care to elaborate? does it mean no cracked motors or ECU's? i.e. stock running gear BUT allowed suspension/wheel/tyres etc?

Intrigued indeed.

Yep that basically it, you can't do any engine mods or any ECU tuning. this class has come about as it getting harder and harder to find parts for the old pre HQ's models which is what the old standard class was made up of. So this class ahs started up and the old standard class will eventually be phazed out. There would be restrictions on tyres as well but i haven't read the new rule book yet.

thing is gonna be a beast, 300kw with 800kg should get up and go

Too right, the old 265 HEMI was very quick and that would have actually been making less than what we always thought it was, but the old chassis was very light as well.

The new class will be run with all cars being to the same specs as when they came from the factory, but you can run a welded or locked diff. Don't worry too much about suspension most of the modified cars still run reasonably soft suspension. the biggest gains are from finding the right tyre presures. If you already have a old street car with some mods, it will fit straight into modified saloons. Because of the expected amount of cars and varying performance, we may even split the modified saloons / openwheelers in to a separate A and B class.

Good to see a fellow Legnum owner :- do you own the white legnum seen around windsor gardens.

G'day Matt! Welcome to the forums.

I've been meaning to get back to you about the rest of the R33 engine bay parts (fuse box cover, dipstick, ABS cover etc) Will call you in a few days. Once it's all done I'll stick a bunch of photos up on here and get the ball rolling :P

Good luck with the dirt circuit racing venture, and the new car. Any info' on when we can go and watch some of this kind of racing?

PM me your postal address and a phone number and I will send one out. There are no jags out there yet, but there are a few openwheelers with your running gear. I recon your jag would be fairly competative, it would definatly be hard to pass when you throw it sideways into the corners.

---------------------------------------------------------------------------------------

No worries Matt. My machine has been down for a while and I have only just got it up and running.

In july there will be an open day so if any one is keen to see these cars do some laps you are more than welcome.

Cheers

dirt circuit is allot of fun we have about 50 cars up here who race, we have an rx-7 with a 350 supercharged, open wheelers with 600+ horses and many others oww and the states best driver, hes good. youll have fun if you guys decide to gett into it but its pretty dear sport in the end. oww and just noticed that rd50 open wheeler is from roxby thats wobbly hes spent a shit load on that thing and its proven.

Hey Matt,

I actually met you at a Charity Cruise starting at Ingle Farm last year - you brought your legnum to the start but parked it over near the shops and I introduced myself :D

Street stock sounds like a lot of fun, and I'm thinking a cheap/banged up EB/ED Falcon 5sp would be a whole lota fun for very minimal outlay.

nice writeup matt i finally got my 5 stud conversion done :):D on the drilled rotors though i passed them on to someone else to live a little longer :P

Good to hear from you again. Hopefully we should have some trick parts for your car on the site in the near future.

Cheers Matt.

Good to hear from some Roxby guys. For sure if you want to compete against any of the top cars from up there you'll need a bit more than a grand in your pocket, especially if you racing guys like Wobbly & Geoff Munro, big hp cars and a big set of balls to push the cars as hard as they do . Hopefully next year we can bring a few of these Adelaide boys up to give the Roxby crue a bit of competition :D .

I've been looking for a picture of Ricks insane blown RX-7, how about posting one up.

No worries, I can give you a rule book so you have some idea of what is involved. Pm me your address and phone number and I will mail one out.

Cheers Matt

do you need to go for a medical like when you race speedway ? the lincense and insurence cost for speedway has made a lot of guys leave the sport .

there are a lot of ex speedway cars that prob would fit right in with you guys i would like a copy of a ruleand spec book if thats possiable

cheers dean

Hello Dean

There is no medical and drivers are covered by insurance. For sure ex speedway cars will fit in with minimal modifications. I can send you a copy of the rule book if you pm me your address and phone number. If you need any extra info join www.dirtcircuitsa.com, the guys on there are very cluey on all things dirtcircuit.

Cheers Matt

Here is a recent video of a mid mounted v8 falcon on a verry loose track :-

    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
