ws9 smooth power great top end x10 smooth power good top end F11 brute power bottom to top its not about port its the characteristic of the engine. The ws9 never had brute power but had great top end and very smooth.It was made for 1/8 buggy not truggy same as the x10 made for buggy.The f11 was made for brute power.Even reno said he races the f11 in his truggy not buggy in the usa.
