Yes figured it was slippery. Brute power not always the answer (ask the xu-1's when it rained) Standing 1km a bit of a different ask out of a car than 400m. Also no slicks and no ideal surface. Any cross wind?
I still was surprised some of the 4wd with the better distribution traction controls (ie nissans) couldn't do more than 272kph.
Most important what was the event like?
Drags have never been my scene but 1km on road rubber is a tempting challenge.
Or at least ask them to make sure the track goes down hill if you have the awesome grunt of the 1.9 I suppose
Tell you what Mr Apple Pie that sunbudgie might be rock stock original factory, but she still has ever bit of Hp that Holden blessed it with. 
Fancy Italian machines should be scared of the brute force of the budgie.
Its got "radial tyres" the same diameter they use in F1.
It doesn't need fancy traction computers or 4wd. Plus it is yellow with wood trim and has the scottish kilt pattern trim so that's got to be worth something?
