Club Dyno Day

JK Performance & Automotive

Unit 4, 122 Long Street Smithfield NSW 2164

Sunday 11th April 2027

Motorsport Australia Social (Non-Competitive) Event Permit no. 7424

The HSV Owners Club is holding a Dyno Day for Club members at JK Performance, Smithfield.

To celebrate the installation of his new Hub dynamometer, Jason Kouzoukas is offering Club members
two power runs on the Hub dyno with an A4 dyno chart printout for framing, at half the usual $400 price, just $200!

This Dyno Day will be open to all vehicles owned by Club members, including motorsport vehicles.

If you are interested in entering your car we would suggest you get in early, as there are limited spaces.

There will also be trophies for the highest power runs in the below classes:

Owned and operated by Club member and supporter Jason Kouzoukass, JK Performance recently relocated from their premises at Wetherill Park, to a new workshop in Long Street, Smithfield which now has a new hub dynamometer which has now enabled Jason to enhance his performance vehicle tuning services.

JK Performance also offers a broad range of other automotive services, including:

Log book and new car servicing

General mechanical repairs

Tyre supply and fitting

Engine building, including Holden, Chevrolet LS, and Ford engines

Performance upgrades and modifications

Servicing for classic, muscle, and older vehicles

Pink Slip and Blue Slip inspections as an authorized inspection station.

A hub dynamometer connects directly to the vehicle’s drive hubs after the wheels are removed. This eliminates tyre-related variables and provides highly repeatable power measurements, making it an excellent choice for professional engine tuning and development.

• Greater accuracy – Eliminates tyre slip and tyre deformation, giving more consistent power and torque readings.
• Excellent repeatability – Successive dyno runs produce very similar results, making it easier to measure small tuning changes.
• No tyre limitations – No concerns about tyre pressure, tyre temperature or worn tyres affecting results.
• No wheelspin – High-powered vehicles can be tested without wheelspin, even at very high torque levels.
• Safer for high-power cars – Reduced risk of tyres failing on the rollers during high-speed testing.
• Handles very high horsepower – Many hub dynos can accurately measure power levels beyond the capability of many roller dynos.
• More stable vehicle – The vehicle is rigidly attached to the dyno, reducing movement during testing.
• Better for traction-control vehicles – Some modern stability and traction systems operate more predictably than on roller dynos.
• Ideal for calibration work – Preferred by many professional tuners for ECU mapping because changes are easier to detect.
• Excellent for race cars – Vehicles with slick tyres or aggressive differentials are often easier to test.
• Reduced tyre wear – Tyres are removed, so there is no tyre wear during testing.
• Lower noise – Eliminates tyre-to-roller noise, making engine sounds easier to hear during tuning.

Trade-offs:
• Wheels must be removed before testing.
• Setup generally takes longer.
• Not every vehicle has compatible hub adaptors.
• Hub dynos are typically more expensive to purchase and operate than conventional roller dynos.

For serious performance tuning—particularly turbocharged, supercharged or high-horsepower vehicles—a hub dyno is widely regarded as one of the most accurate and repeatable dynamometer systems available.
