VF GTS: heads, cam and boosted pulleys

750 rwhpat the wheels on E85

An HSV VF GTS fitted with our heads and cam package, Harrop boosted pulleys and a full exhaust, making 750hp at the wheels on E85.

This VF GTS is the latest car to roll out of the workshop. Our heads and cam package does the heavy lifting, with Harrop boosted pulleys adding boost and a full exhaust letting it all out.

Tuned on E85 on our hub dyno, it made 750hp at the wheels. Proof that a well-matched LSA combination can run with the big-cube strokers.
