[QUOTE="ALBundy, post: 110151, member: 15"] As mentioned previously by F8 in another thread, the formula to higher Bhp is mainly due to engine compression ratio and also the rpm. WE have seen an increase in bhp over the years and there is nothing high tech about it. Engine theories (gas/combustion cycles specifically) still remain the same after 100 years. What is happening is the advancement in the field of metallurgy (which allows lighter and stronger internals to be built) and mechatronics (control systems and etc) that allow engineers/designers to maximise the potential of these theories. For instance, usage of exotic metals has allowed designers to increase compression ratio to above 11 and rpms above 8000 in many of the cars listed above. :) Al [/QUOTE]
