Ba Bow - I think they are 1.5 Litre 4's and V6's from memory, and in qualifying trim I believe they used to belt out around 1,500 horsepower. Nothing like 4 bar of boost to get the blood pumping.
I was down there on Sunday. It was freezing and windy, but we go every year so wasn't going to miss it.
Was in the Winfield R32 pits for ages looking at how they dealt with the tremendous heat load those things would have had to deal with over 1,000 k's of bathurst.
Had the mental notepad going overtime.
A great weekend and a must see for any motorhead.
