I bet there is a disc valve and expansion boxes in ther somewhere...
I still thinkt they'll say it will struggle to break the 200mph barrier due to aerodynamics.
Does anyone remember the CBX1000? looks remarkably similar.... this time round I cant see how making the indicators the size of dinner plates, or painting it silver will make the thing look smaller though.
Anorak time here but i think they are Rolls Royce Griffon engines. They produce about 2500hp at 2750rpm and we used in later marks of spitfire (XIV etc). The right hand one i think is a marine version as used in air sea rescue launchs or it might be from a tank.
