My knowledge is limited, infact i wud say very limited, but im keen to learn. Luckily one of my mates knows cars in and out, his knowledge astounds me and my other mates all the time, he makes many of his own parts for his current car, its last dyno was 460bhp on 95ron fuel, it will soon be more than that, as its always, as he puts it 'in development', and a few things have changed since its last run.
