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.

wow, thanks Aaroncake

If anyone has had dyno results with the ports not working and then cleaning them and dynoing again post the before and after numbers.

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

Well.......
I do have the Duals:bowdown:

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

5th and 6th to me cuz I have a six port engine just like every one else here ass hence 1st 2nd 3rd 4th 5th and 6th ports idiot

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

WOW, is he a troll or something? Did I missed something?

I duno but I kinda like the guy already. :)

LOL! this is all too familiar.

LMFAO!!!!!!!!!!!!!!!!! now THIS is what im talkin about, LOL.... tell em tiger.

Wow, there are some really immature people on this board. :o:

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

I will!!!....:D

I am not immature just an ass.

What are they officially called by Mazda?

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.

I thought all 2nd gens were 6 port?

I think all FC's have six. I never heard that aboutl TII's I think you might be mistaken dude.

TIIs are 4 port. NAs are 6 port.

wow

Yup, all TII's are 4 port. all N/A's 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?

Ask Aaron, he should know the answer to that. ;)
