Ive seen no evidence that danny's is specifically over 500bhp yet, although its certainly up in that ballpark judging by its brunters speeds.

Will be cool seeing them both run the standard km in a few weeks, that should show who's is making the most power, although specky is FAR more bothered about quarter mile performance than out and out power anyway as far as im aware so im sure his turbo choice reflects that rather than a quest for the highest possible power.
