Which vacuum lines are OK to block off? Can anyone draw arrows pointing to what lines are ok to block off or re-direct?

As you can see below, I am blocking that line with a screw. Where can I get the REAL "blockers"?



And what do I do with this? An aftermarket intake doesnt have a place to put this like the stock one does.


I wonder if anyone is gonna help. This forum tends to ignore my requests for help. For anyone that does help, thanks in advanced!

bump for the night crew! good night!

 

The line for the air boost valve that you have in the second pic might not be needed at all. JDM motors do not have an air boost valve so I wonder if you could just uninstall the whole unit. Does it have any sensors attached to it?

I'd also like to know where to pick up some "blockers".

Also, the rubber boot on your throttle cable needs slid up so it covers all of the cable.

 

So does anybody know if I can just cap it off? or just leave it open? maybe route it somewhere else?

 

when i installed my intake, i ended up removing that entire blue circled piece in the second picture. not just the blue circleded rubber part, but even the plastic part after that.

i ended up plugging two lines, one in the back of the IM (red circle) and one in the front (where that plastic tubing leads to). you can get vaccuum plugs at napa, autozone, etc.

 

If you pull the secondary butterflies then you can plug that vaccum line up as well.

 

I agree, i believe that line controls the secondart butterfly's, so if you remove them of, keep them open, you don't need that line hooked up

 

essentially you should beable to block off all your vaccum lines. your car should run, but who knows how good it will run. block it off or 'T' it to another line, as long as your not throwing a code right?

 

what if you still want to use the secondary butterflies? what would you do?

 

Not sure, The when you get an intake mainfold rebuilt nice they usually take them out, its is one of those tricks of the trade to get a little more juice out of the motor

 

I'd leave that line connected then.

 

wut are pros and cons with the secondary butterflies?

 

but like the original poster said.. there is no place to connect it to in an aftermarket intake.

 

If anyone is interested this is probably better than just disabling the butterflies since it removes that impediment from the airstream entirely.

Though you really should buy some 1/8" vacuum stubs.
