air pump
got a question. i have an 88 na engine in my 87. i have removed the air pump. does this affect the 6 port actuation. i have racing beat cat replacement pipe and silencer with the return pipe running back to the actuators.
thanks i love my 7! |
You should fine. 89 was the first year that the airpump was required for 6-port actuation.
|
In the '88, the sixports are opened by the backpressure from the cat. Since you've removed that, you probably aren't opening the sixports.
|
There is sufficient back pressure in the RB front pipe and resonator to actuate the ports on 86-88 cars.(assuming of course that actuators are free).
