If engines are members of a choir ensemble, which would be the soprano? I’m wondering, purely on hypothetical grounds of course, what the highest-screaming engine would be on a budget. Ideally parts should be readily available and relatively cheap.
The Honda F20C looks nice with its 9,000 rpm capacity, but it only has four cylinders. Are there any other engines (within the realm of four-wheeled vehicles) that sing high without being prohibitively expensive? *cough* *LFA* *cough* *any V12* *cough...*
