V6 alloytec manifold for Holden Commodore, Rodeo, Colorado

Our revolutionary CPR6 V6 Commodore manifolds extract the best out of your Holden V6 alloytec four-valve engine, without the need for a thirsty V8. Our most recent dyno'd engine produced 422 bhp.

But you can easily put one on your daily drive and enjoy extra power and fuel economy.

Using years of cylinder head airflow research into volumetric efficiency, we've spent hundreds of hours at the flow bench to obtain the maximum horsepower from V6 alloytec manifolds.

We can work on just your alloytec manifolds to increase power, but we can go as far as you'd like to gain maximum powersuch as fitting Motec.

Our methods can be used on any alloytec V6 including Commodore SV6.

Watch the 444bhp engine on the dyno

Yes, that's right 444 horses from a naturally-aspirated V6 Alloytec engine. Tuned by the renowned Phil Laird at the engine dyno at KV's Fabrication in Maroochydore. Note the figures on the screen are the uncorrected figures, so we've also included the corrected figures in chart form below. We're confident we can get 500hp in the near future out of these engines so if you're keen to know more, get in touch.

The video below was taken in 2008, with the engine that you see on the engine dyno the same one that is in the Performance Manifolds ute seen at the start of the vid. We are now pulling 444hp.
