Kallangur.. we used to live out there
As for the burnouts, nope, will have some incar video & some high speed runs soon though
Its pretty awesome to drive now, breaks traction in second just under its own acceleration (no clutch input) on a flat straight road, you can cruise along anywhere between 1k and 5k in second, stand on it and it'll smoke them up

Well just took some videos of the car with the stock intake, probably the last video of this setup.
Diff is on the way out so had to take it pretty easy on gear changes, hope you enjoy!
I am using this host tempararily until my ftp gets sorted out, shouldn't be long

Nice setup, it's always good to see antipodeans do well
What are you planning on doing to get more traction? Seems little point in running a 20B unless you have the ability to put it to the ground?
Not knocking you mate, just wondering what your long-term traction goal is. Tubbing? Although I reckon she'd be right with a 8.8" Falcon diff if you're going N/A, otherwise a 9" might be on the cards?

I just got off the phone to my engine tuner.
Had custom intake fitted which was for sale on here, car has just made 295 rwhp.
Previous best was 245 rwhp, this is on a Dyno Dynamics, so although it might not sound much to you US guys, our dynos do read 15-20% less than Dyno Jets etc which would put it up around the 340 rwhp mark.
Will write up a bit later after I have driven the car to compare the differences

I'm still running the stock open diff with 4.4s and a 12A Turbo gearbox, so not really keen on taking it down the strip with this driveline, as I know it will break something.

We are doing up kit for crossmember etc if anyone is interested. Will cut down on the cost of a conversion quite a lot if getting a workshop to do it.
