Oztrack’s guides are based on work completed in our Penrith workshop rather than rewritten product descriptions.
We combine dyno tuning, engine rebuilding, cylinder-head preparation and engine machining. This helps us assess the complete combination rather than looking at one part alone.
Our team has extensive circuit-racing experience. Dan was an Australian Champion in his class, and Jono has worked with V8 Supercar teams. Oztrack also sponsored the Motorsport Australia Super TT category in 2026.
