Welcome to the West Australian Limited Sprintcar Association.
Our club is comprised of approximately 80 members consisting of over 30 drivers with the remainder of the members being family, support crew and club associates.
The majority of our members reside outside the Perth metropolitan area so the club regularly races throughout Western Australia, including south down to Manjimup, north as far as Carnarvon and of course east to Kalgoorlie.
The club committee meet regularly each month to plan and co-ordinate racing events and general club business. In addition to this the club members set aside time for a general club meeting a couple of times a year to share ideas and a few cold drinks. Each year on the last Saturday of June the club holds it's Annual General Meeting which also coincides with the end of seasons Trophy Presentation and Awards evening.
Our club proudly supports a strong social atmosphere with many a cold drink and a hot sausage bun being consumed after the conclusion of each race event.
If you have ever considered racing sprintcars or even just have an enthusiasm for sprintcar racing and would like to be associated with the club as a member, please feel free to contact us at club@limitedsprintcars.com.au or come along to one of our racing events and have a talk to any of our friendly club members to find out more about us.

Limited Sprint cars run a V8 engine and are constructed from tubular frame chassis. Within this chassis located just in front of the rear wheels is the driving position. The driver cockpit is provided with minimal instrumentation and usually only consists of an oil pressure gauge and a water temperature gauge.
Besides the obvious requirement for a steering wheel, the driver controls are limited to an accelerator and a brake. There is no soft clutch or driver selectable gears. The vehicle driveline is only fitted with a “dog clutch” which enables a go or no-go option.
These vehicles generally run a hydraulic power assisted steering system; with the steering hydraulic pump being mechanically driven off the engine.
Limited Sprint cars minimum weight is 1625 Lbs, as you can imagine weight can pay an important part of being competitive so considerable work is done by the vehicle builders to keep as close as possible to this weight.
Australian limited sprint car engines are restricted to 361 cubic inches with the most popular engine in use being the Chev small block 350 cubic inch engine.
Sprint car engines are naturally aspirated carburetor engines fueled with methanol, which provides a higher octane rating of 113 compared to 98 octane being the highest available octane fuel at public service stations in Australia.
As this higher-octane fuel will provide better resistance to detonation the sprint car engines can run higher compression ratios and thus produce more power from the same size engine.
The fuel tank is mounted at the rear of the vehicle and is generally constructed from plastic with an internal safety bladder.
The sprint car wheels are more important to the racing than one would first think. The vehicle can be setup to suit each track surface and conditions using a variety of tyre diameter and widths (front to rear and left to right) and by running different air pressures on all tyres to best suit each days racing.
Tyre pressures can vary between 3 PSI and 10 PSI, with the inside tyre (left) generally having the lower pressure as this tyre has reduced weight on it while racing due to the continual left turning of the vehicle.
Because the tyre pressure can be so critical to the vehicles handling the tyre valves are commonly fitted with bleeders that allow the additional build up of air pressure as the tyre gets hotter to escape and thus maintain the correct pressures selected by the driver prior to each race.
In the early 1970s, many sprint car drivers began to put wings with sideboards on both the front and top of their cars. The added wings increased the down force generated on the car, with the sideboards helping to turn the car in the corners. This makes the car easier to control.
The added down force also lessens the likelihood of getting airborne. However if the sprint car does get airborne (rarely), the wings frequently break off and absorb some of the impact of the flip, thus lessening the impact on the driver.
The wings are adjustable with increased angles increasing the down force on the vehicle which increases traction and stability but also has the negative effect of also increasing drag and thus reducing the potential top speed of the vehicle, so it’s a balancing act to get the best settings for each track.
To provide some safety to the drivers the following key items are built into the vehicle or worn by the driver.
Fire resistant clothing, including underwear, gloves, boots and balaclava.
A 5-point safety harness
Arm restraints to prevent the driver’s arms going outside the roll cage.
Neck brace (sometimes called a horse collar) to provide additional neck support.
Full-face helmet, usually fitted with clear vision tear-off’s in an attempt to maintain visibility with all the mud and dust from the race. Additionally, helmet restraints are sometimes used to help offset the forces of the constant left hand turning vehicle during longer races.
