223kms for mini and an unofficial land speed record doesnt seem very quick to me.
Im sure i remember seeing footage of a J car hit 200km's. And wouldnt have had a super charger or twin cam head.
you've gotta put it in perspective - yes, GR's Nb car hits ~203kph at Eastern creek, at somewhere around 8300rpm - and it's flat out, can't go any faster, and if he tried to maintain that sort of revs and load for any amount of time (the main straight at eastern creek only lasts 20 seconds or so), the engine would fail very very quickly
Now, think about your own car, if it's flat out at (say) 160kph, and you wanted to push it up to 180kph, what sort of modifications would you need to do? now push it up another 20kph, and then another 20kph. But what you've gotta remember is that every little bit faster you go, the air gets harder and harder to push through. Maybe that first 20kph takes another 15hp, then the next 20 takes another 30hp - and you've only just broken the 200kph mark... that extra 20 is probably another 50hp
The aerodynamic forces on a mini are huge - and that car still has it's body seams
and then make it survive repeat runs over a long distance at the utter utter limit of it's power
what those guys are doing is absolutely astonishing
