| A bigger blow off valve gets rid of the extra air when you come off the gas and, a larger swing valve and actuator is added to the wastegate for boost pressure control. Finally, the Unichip computer is retuned. At Phase III power level APS recommend that the auto transmission be upgraded along with the valve springs, which are a little bit soft on the standard car.
Does it do the business? Try 390kW at the flywheel or 309kW at the wheels, recorded on the APS dyno with full boost between 13 - 14psi in the mid rpm range, dropping off to about 12 or 13 at redline.
It's called, real street cred and for Mark it's about having a docile daily driver one minute and, what is Australia's fastest 'street legal' XR6T Ute the next.
"The car is amazing on the road. It drives just like a standard injected six below 3000rpm. Above 3000, it starts wanting to play, first and second you can loose it
fairly easy, it just launches. Second gear is normally the most fun gear in any car and you've got that right through third and fourth too."
"Calder was an interesting night, it frightened the living daylights out of me because I ran slicks, so you hook up a fair bit better than with street tyres. I decided I was going to give it a good amount of time between runs so I didn't cook the auto. Going by my dyno sheet now, I've got about 750Nm of torque, so that's going to fry pretty much any auto if you give it too much curry."
