Standards = about 400
Non standard could do a lot more (1000bhp ones in the states running as road going daily drivers http://www.houston-imports.com/index.ph ... &Itemid=35 )
Its not all about the engine at that level.... chasis, brakes, gearbox, running gear etc etc.
Yeh I think he was upto about 500, but I think Alex may be getting more...
