I had the opportunity of taking one for a test drive around northbridge (so I couldn't fully open it up) and the dealer wouldn't let me take off the traction control.
I was quite impressed.
As already said it runs at low boost and has a small cooler. Any modification whatsoever will void the warranty. Ford are a bit concerned about the gear box not holding up to much more boost.
But let the xr6 mature- it could turn out to be a true monster. Once the warranty run out watch as people do the same things to them as get done to skylines and vl turbos, cooler, boost etc.
ps. the rumour is that all ford testing was done at 270kw and then it was engineered back to 240 to preserve the warranty- but the point is it is good to go at 270 as is.
the weight will be a big problem and dont see how they will get around it. People buying an xr6 apparantley want all the fruit- half a cow, arctic a/c etc.
Should be interesting to see if holden try and keep up by putting a huffer on the new v6 comming out of fishermans bend in a couple of years. supposed to be a very nice mill.
And after all this would not be holdens first flirt with a turbo commodore. All hail the vl!
