HOLDEN SUPERCHARGER 6 BOOST UPGRADE. SUITS HOLDEN VS-VY.
New supercharger boost upgrade kit which comprises of a special modular hub, 10psi pulley & installation instructions.
(Please note you will need a pulley removal tool to complete installation)
A very cost effective way to bump up the performance of your factory supercharged 6 Commodore, by increasing boost pressure!
Manufactured by a renowned engineering company you can be assured that the quality of this kit is second to none!
This mod is an excellent cost effective way to bump up the horsepower from your late model commodore as shown on the dyno graph below. In this case we have a VT Commodore with extractors/exhaust/cold air intake and our 10psi boost upgrade, making an outstanding 146.8 kw at the rears. An increase of 15kw from stock, and with no tune in sight! Just goes to show how much Holden really watered down the performance of these engines… Please note that 98 octane fuel must be used when running boost levels of around 10psi on a standard engine.
Backed up by other tests, this mod is good for around 20 kw at the rear wheels for a car with similar mods as mentioned previously. Greater power gains can be achieved if further mods are undertaken such as an intercooler, larger cam, etc…
The best part about this mod is that at the very most, takes about an hour to do! Unlike others around, there is no need for removing superchargers, replacing gaskets, and spending hours and lots of $$$ to achieve our results. In addition, once our special hub is in place, changing of pulleys literally becomes a 10 minute job! Such that you can now easily swap from a 10 psi pulley for the street to a 14 psi pulley on the track, if you wanted to. It’s all quick and easy.
Also for an extra $200 on top you can purchase a new pulley removal tool,
