12a port timing question
Does anyone know if the primary and secondary intake ports open and close at the same time?
|
Yes |
Thanks. Looking into intake runner length and resonant supercharging and if they open at the same time you can get the supercharging effect with a shared throttle body per rotor where as you usually need ITBs.

Opens the same if they are ported the same |
Mazda did that with the vdi intake on the s5 it was worth 35 hp |
