Home of the CPR6 V6 alloytec and CPR8 LS V8 manifolds
Welcome to Performance Manifolds, the home of the CPR6 inlet manifold for V6 alloytecs, and the V8 LS twin-throttlebody manifold we call the CPR8.
CPR INTAKE MANIFOLDS = HORSEPOWER
Using our years of experience in flow-bench technology, we breathe life into your V6 alloytec or LS V8.
Add 20rwhp to your V6 alloytec
You can add 20rwhp to your alloytec V6 in a couple of hours in your back shed, right up to a maximum 444bhp with one of our full CPR Holden V6 intake manifold setups.
Or you can try any of a dozen combinations of add-on parts and still be assured that our manifold will increase the power by the same amount regardless. If you've already got a better exhaust, our manifold will add another 20hp.
On a standard engine in the family VE sedan, the modified manifold returns 8.6l/100km which helps the family budget. Best of all, you can unbolt it if you sell the car and fit it to your next alloytec.
500kW streetable LS V8
The CPR8 Holden V8 inlet manifold setup can get you 500kW from a standard 6.0 litre LS V8 with just a set of extractors, cams and exhaust. No supercharger, no turbo.
How do we do it?
Just like a performance athlete, breathing better is the number one step to better performance.
The CPR intake manifold allows far more airflow and therefore far more horsepower.
And better still, it still returns 11 litres/100km fuel economy average.
