Question How much hp would non-operational 5th and 6th ports take away?
I recently discovered that one of my auxilary ports is stuck closed. how much hp am I loosing? I will clean them during springbreak but I want to know how much power I have been driving without. I only discovered that the port did not work after I got my True Duals and removed my air pump.

It's rather subjective, but my opinion is 15 HP. Both stuck closed would be VERY noticable, and probably a loss of 30HP or more top end.

I saw a streetported car make about 150HP closed, and about 180HP after they were wired open. This was with a full exhaust.

just for clarification the two ports on the lower intake manifold are both six port actuators, not a fifth and sixth. FYI

It is a logical numbering because you can't have two sixth ports dumbass. They are "Auxilary" ports anyways so STFU

I've been calling them 5th and 6th (because they are the 5th and 6th ports) for years now. Want to correct me?

Auxillary ports... People just use 5th and 6th because thats what they are , a 5th and 6th port. The T2 has a 4 port engine, and the N/A FC engines are 6 port.

ohkay.. well i'm learning lots here.. so if a turbo is put on a NA.. would it put out more power, because of a higher compression ratio and more air at higher RPM's?
