This is on a GSR manifold. And i was looking around threads and i even saw a video but i cant really tell if my secondaries are always opened or not. When i rev and look at it them they dont move (and i rev to 7500). So are my secondaries connected on, or are they closed or what?

Heres a pic:



TIA!


Edit: Also when i move it by hand the only way i could turn it is down ( clockwise)

 

not 2 steal your thread but can you rev you engine 2 5800 and watch to see if it opens up, or does the car have 2 be moving?

 

I dont think you need to be moving, because i found in the archives (cant remember the thread sorry) of a video where the guy just reved his car to VTEC, then went further and the secondaries turned on. So you could do it without moving.

 

just zip tie them open

And which would be opened and which would be closed? Thanks for the help

No, because the ECU does not expect that kind of airflow, so it has to make big adjustments. that means it will actually run worse. no matter what your butt dyno says.

thats nearly the same as just running vtec all the time. stupid idea.

While your first statement was correct, your second one is totally off... its no where near the same as engaging vtec below the stock point. its chaning the timing, cam lift duration, overlap, ect.

Much different then "letting more air in" But yes it is a stupid idea to zip tie it open.....

BUT, a few people i know running turbo gsr's with stock Mani's keep theres open, as it will not open under certan conditions, i believe its after 7psi of boost when it will not open up.

i was trying to make a comparison they could understand, i know its nothing like running vtec all the time.

 

it wont run worse,but in lower it will take of slower. once it passes 3-4rpm,s it takes of.

 

Ok we got off track but i dont mind because its information on the subject. But can someone please tell me if my secondaries are open or closed from the picture. Thank you

 

nope ur secondary aint hook up

 

So in that picture thats them closed then, correct?

um slower = worse lol

 

They're spring-loaded open, so if they aren't hooked up or there's a problem with the vacuum, they'll still be constantly open.

Correct.. i made a thread about this and some people were trying to say they were always closed.. thats wrong.. they close when there is vacuum (engine on) and open when there is a signal to the switch.. but if its not wired up they wont close at engine startup..

 

So there always open then? Next question, is there anything bad about them always being open? Like would i have a problem with it, even though i havent had a problem for over a year and i didnt know about it til now.

 

No i doubt they could cause a problem.. I've also been driving around like this since i got my swap.. 6 months or so.. no problems..

Others swear that you lose a lot of low - mid end power.. I don't doubt that you loose power but I never driven with them properly functioning so i wouldn't know the difference...

The only problem would be a performance loss... how great that loss is I wouldnt be able to tell you..

 

o ya always open haah hook up the secondary

 

i know on h22's that if you take the secondaries just completely off that you lose just a few lbs of tq but gain almost double the amount of hp that you lost in tq. i'm sure its the same way...

at least thats what we saw on the dyno....
