i've been reading his build up in ppc and it is a stonking bit of engineering, regardless of what the end reslut is going to be you have o give him credit for attempting it
also, the engine is only going to be puttin gout arond the 500lb/ft mark because he's useing a bus gearbox with a 3:1 step up ratio to give him 6k+ rpm (which he reckons will be good for 200+mph)
seeing as there are only 2 seirra's i know of that have cracked the 200mph mark, and only one of them is a road car, it's better than 99.99% of the people on here have done so i'd think about what you were typing before giving him a hard time over it
it may well be over wieght and your onions may be the same as the other 99.99% of pf, but he's built it for himself, not for someone else
