227 MPH out of an Audi 3.0L TT V6

[Insomniac]

An Audi A4 has set a world record for a biogas-fuelled car, hitting 227mph in the hands of German racer Jurgen Hohenester.

...

But the silvery saloon is powered by Audi's twin-turbo 3.0-litre V6, modified to run on compressed biogas and putting out a frankly loony 700bhp.

I wonder how much you have to modify th stock engine so it runs with bio-fuel?

You know it's been a long day when you read biogas and pronounce it 'bwuigus' in your head. I was like..."what the heck is 'bwoigus?". I need a beer. :gomer:
