A friend with a supercharged au1 xr8 had all sorts of problems.
The sheer flex in the engine on acceleration damaged all the pulleys and belts on the front of engine. Had to get extra bracing for engine. I think off memory that he did a couple of diffs. Blew a fuel line and caught on fire. Drank two litres of distilled water for a tank of fuel. It was all worth it to watch 247rwkw blow away the opposition on every occasion.
I've only had one problem with the blower belt and that was when I missed a gear whilst on the track. Belt jumped forward one track and tore itself up. Was easily fixed by having a pulley, with a lip front and back, machined up. (and by me not missing gear changes :s3 )
As I've mentioned up top, I've had no driveline problems, but I do treat it with respect, while still giving it heaps. :s5
On the track my car drinks 2 litres of water through the water injection within 5 laps! Normal driving with the occasional "giving it some", I rarely need to fill it up more than once every 2 tanks of fuel.
And yep, it's more than worth it.
