i quoted this from another forum!:)
For any one that want's to know I work at the company that provides OEM exhaust systems for all 4 car manufatures in AUS.
Ford have had us testing exhausts for them for the last 7months in prep for the Barra they've changed everything but the doors on the car . The test cars they gave us had all the AU panels and interia but the new DOHC cam is a wet dream. Smoother than some of the BMW I6 motors our DEV section have got to drive!
The new suspendtion is straight from the Jags and allows massive power to the ground with out skipping and traction control. The Falcon's getting a full stainless system and we were told to get max power figures and than just make it quite.
The most we got from the flywheel was 210kw from the standard Base model new motor but it was to loud so expect to see the car at around 175-192KW the turbo was easy to get massive power as the stock motor only runs around 5psi.We got just over 270kw with out anything but changed exhaust and boost up to 9psi. Expect that one at around 230kw.
The Mustang motors are more of a secret for some reason and our tech guys had to go to Ford melbourne to do the testing so I don't know what we'll see from those things.
The commie is going to get killed in performance untill the new engine plant gets going as we really can't get more than around 160kw NA with out reducing the reliability of the engine. To old a design and really get's asmatic if you rev it to high exactly the oposite to the Gen III really.
There is word of Holden uping the gears to 5 speed auto and 6 speed manual on the stocker commies so they can up the end gear ratio for quicker speed. Didn't get to see what holden are doing for the shape and style of the car for the next model. Most of the engineers seam to think all they can do is make more of the calais stuff standard on the Commie but Holden are really really scared of changing the shape much at all. They want the new monaro look on the next gen but there scared of having to remake the monaro so as not to piss off the current owners.
The main problem is that they don't want to do a Ford the au was a disaster and holden were actully prepared to copy the car in several respects had it not been such a failure.
I'll post this in the general section as well as most people would probably want to know.
