Power Torque Performance

Stage 4? Stage 5? You tell us.

This HSV Clubsport came in for a full engine-out rebuild. Not a bolt-on. Not a part-by-part job. One planned build, start to finish.

What went in:
- Engine out for full access
- Cam package with upgraded rocker trunnions
- CNC-ported cylinder heads
- Race balancer, all gaskets replaced
- Harrop FDFI 2300 supercharger
- Twin-plate clutch
- In-tank fuel pump upgrade
- New O2 sensors, AC line and regas
- Full custom dyno tune

Even we can't agree in the workshop on what stage to call it.

Where do you land? Comment 4 or 5 and tell us why.

The dyno pull is coming later this week.

Two runs, two peak numbers — but the number on its own doesn't tell you which one's actually better.

Look at the curves instead. The red run hits its peak earlier and holds it longer through the mid-range — that's the one you'd actually feel from behind the wheel, every time you're on the throttle before redline. The blue run peaks higher at the top but gets there later and falls away quicker once it's past it.

That's why a dyno sheet is never just about the top number. Where the curve builds, how flat it stays, and where it drops off all matter more than the single biggest figure at the very end of the pull.

When we tune a car, we're shaping that whole curve to suit how it's actually driven — not just chasing a number for the sheet.

282.6kW / 378.9HP at the rear.

HSV GTS — MCA Pro Comfort coilovers, full Hurricane exhaust with ceramic coated extractors and twin 3" 409 stainless steel system, VCM OTR, custom dyno tune. Dialled in on the Mainline until the curve was clean.

The plate says PUREV8. The dyno agrees.

A proper cam upgrade doesn't start with a cam. It starts with the engine on a stand.

This HSV Grange came in for a cam package — but before anything goes near the heads, the whole engine comes out for a full inspection, clean and reseal. No shortcuts, no reusing tired gaskets just to save a step.

With the heads off and the block prepped, the new cam package goes in, along with a fresh set of ceramic coated headers, ready for the Hurricane exhaust system.

Retune and dyno numbers coming later in the week...

"Had my old man's VE Commodore tuned here after a rebuild and cam upgrade. The previous tuner had locked the ECU, but the team went above and beyond to track down someone to unlock it. Car's now tuned and running great. Thanks heaps guys, not often these days you see a business go above and beyond! Highly recommend!!!"
— Brendan J via Google Reviews

Locked ECU. Most shops would've handed it back. Ours went and found a way to unlock it anyway.

A shop that gets the job done, even with a previous tuner's ECU lock standing in the way.

Thanks Brendan for the kind words — glad we could sort your old man's VE out!

In 1988, Holden built 500 numbered Commodores that had no business looking the way they did — deep front spoiler, side skirts, flared guards, a wing you could land a plane on. Enthusiasts called it the "Plastic Pig." Some called it the "Batmobile."

Underneath the panels: a 5.0L V8 bored to 5.32L, 274hp at 5,200rpm, Brembo four-pot calipers, adjustable Konis, and a close-ratio five-speed — built by Tom Walkinshaw's TWR to satisfy Group A homologation rules, not to look good in a showroom.

It worked. The Commodore SS Group A SV took outright victory at Oran Park in '88 and gave BMW M3s and Nissan Skylines all they could handle at Bathurst. Six seconds to 60, in a car with walnut trim and suede Recaros.

Original price: roughly $47,000 — double a standard Commodore. Concourse examples now clear $200,000+ at auction.

Would you have paid double for one back then? Let us know.
