For years, the Siemens Deka 250 lb/hr injector has been the go-to for big horsepower builds. Drag cars, street cars, methanol, E85—you name it, they’ve been there. But let’s be honest… time has caught up with them.
Prime Speedworks was built at the track, not in a boardroom.
With decades of real motorsport experience, we’ve gone fast across it all — V8 Supercars, Offshore Powerboats, Sprintcars, Midgets, and Drag Racing from Top Fuel to Super Sedan, including the brutal world of Drag-and-Drive.
We don’t chase hype — we back proven performance. Every product we support is chosen because it survives real racing, not because it looks good on a shelf.
If it doesn’t make you faster, stronger, or more reliable, it doesn’t belong at Prime Speedworks.
Prime Speedworks is proud to play a part in the Performance and Racing Industry in Australia and Worldwide, supporting industry bodies and initiatives.
