    I use pressure outlet and see what the massflow is, if you set a target massflow higher than the max. flow through the restrictor fluent would try to achieve the target massflow by lowering the...

    In a test of a magazine the CR of the new ZX6R was given as 13.3:1, which would be pretty good fo a mass produced engine with tha bore to stroke ratio. From my own experience I can say that the...

    I did another run with short intake duration but 10% more lift. This gives me exactly the same results for ve as in the low lift case. Beyond 9000rpm the restrictor makes it's job pretty good, so you...
