VEHICLES

Creating and developing a new engine calls for real world testing. The Radial Motion Fleet is eclectic and eccentric, with each machine providing us with different challenges and different insights.

As you'd expect, our customer builds are unique too.

AERO 356

Ron Goodman is well known in the Porsche scene for his outlaw builds and race machines, always presented in his trademark Goodman Grey livery.

His latest build is an aero-themed outlaw 356, which has been fitted with our first Aero style Radial Motion engine with distinctive air cooling fins.

This classic racer has been built to an exacting standard with some unique touches, and needs an engine to match.

The Radial Motion engine will give it plenty of punch, especially with a dash of nitrous...

ZOMBUG

The ZOMBUG started life as a battered and bruised 1972 Super Beetle. We set about fitting a first generation Radial Motion three-cylinder engine to the car. This was an air cooled version with exposed pushrod tubes and our first generation head design. Dyno tuned in-house, the engine produced 120hp  from its 1.6 litre capacity, some 80hp more than it left the VW factory with nearly 50 years ago. We entered the ZOMBUG in the 2019 Adelaide Rally with this engine, which made the high-riding car a handful on tight tarmac.

Zombug then received a pre-production liquid-cooled Radial Motion engine, which has passed the strict emissions test, making it legal to fit to late-model vehicles in Australia. It has now been lowered, with sticky tyres and a revised roll cage design a better match for the 150hp 2.0-litre engine.

In this guise it was entered in the 2020 Adelaide Rally. That event was postponed and ran in March 2021. Zombug performed flawlessly, with ample power on tap, especially on the wet stages. One minor altercation with an armco barrier didn't dampen our crew's enthusiasm and Zombug continued on to complete the event.

BON-TRIKE

The Bon-Trike HS3 is the ideal test mule for the Radial Motion engine, with its ease of access for installation. 

These popular trikes are essentially a  VW beetle rear end, connected to a long set of girder forks by a strong and light steel tube chassis. They were originally sold with 1200-1600cc VW engines, which were enough to make the 450-odd kilogram trike fun to ride.

We fitted a triple-carburettor version of our Radial Motion engine, tuned to a conservative 120hp, turning the once-tame trike into a wheelie monster until it fried the clutch.

We then took the most obvious next step – drag raced an aeroplane.

Fitting the Radial Motion engine is easy on the trike – so accessible and just four bolts secure the engine to the transaxle.

KOMBI POSTAL VAN

This 1976 VW Type 2 was originally a post office van. It came to us in a well-used state, complete with hippie mural and plenty of rust. 

We've had it tidied up and freshly painted, and it's next on the list of Radial Motion test mules.

We'll be tuning the engine for low-down torque and driveability, with the aim of towing a loaded car trailer on long hauls – not a use the original 70hp engine was well suited for...

COMING SOON

We've got some more interesting vehicles lining up to receive Radial transplants.

There's a Formula Vee open-wheeler, an ultralight aircraft, another VW Kombi and more. 

If you would like to add your vehicle to the list, give us a shout!
