Ok I ran in to a problem today, my turbo kit I had bought has an external wastegate and a place to hook up a vacuum line well my turbo THAT CAME with the kit doesnt have
a vacuum line tap.... So is this necessary or should I go get it tapped tomorrow (which I planed on doing)?

thanx!!!

 

bump b4 bed...

 

vacuum is vacuum.

You can just t it into an exisitng vacuum source.

 

Really? I was just told to run it from the turbo... Thanks.... is there any other opinions?

 

You could probably spend an afternoon reading through all the threads regarding this topic. just tap it and see what works better for you. you can always stick a plug in there.

Personally, getting the signal from the source (turbo) makes more sense to me but I haven't really played with a lot of boost control toys.

i really hope this is a joke

 

do a search.

There are tons of people who say you can either tap it, or t it into another source.

Dont make a mockery out of what I say.

You have no idea how many times my friends dad(who is an engineer) has bitched me out over this subject. I ask him about tapping the turbo, and he's like blahblahblah vacuum is vacuum, it doesnt matter.

It may be slightly slightly off, and i mean by a tiny amount, but its not gonna be that big of a difference.

Your car is either pulling vacuum, or its in boost. It's not gonna be in vacuum in some places, and not in other places.

the wastegate does not need to see any vacuum ever. tial say's to put the boost pressure source before the throttle body. so at any point before the throttle body, charge pipe or even on the compressor housing of the turbo is where you want that hose connected.

the wastegate needs a pressure source....not a vacuum/pressure source......maybe your "engnieer" need to spend more time in school......

 

but isnt it all still the same? You can t it into the brake booster or fpr correct?

I apologize for some of my wording being incorrect, Im fairly new to the subject. I didnt mean to say or imply that the wsategate needed to see vacuum.

And dont insult the engineer, you have no idea how intelligent he is.

 

re read what non vtec said. It needs a pressure only source. the fpr or brake booster is a vacuum/pressure source because it is after the throttle body. the source on the compressor housing is a pressure only source. it is either at 0psi to xxpsi.

 

I know it makes sense what he said, but its going to get a pressure reading no matter where its at.

It's probably optimal to hook it up to the compressor, but if it was 100% necessary all the time, wouldnt they come pretapped?

Also, my wastegate isnt connected to a nipple on my turbo. It's t'd into the brake booster like. The pressure from the turbo goes through all of the vacuum lines. So why would it matter where it's placed?

I did some searching, and people have recommended either way, without any way that's right or wrong.

I simply stated the easiest way for him to do it.

If I'm wrong, find a link or something explain it to me.

But through searching, ive read tons of threads about this topic, and none of them say either of us are wrong. but my way is a lot easier.

 

sorry for not read this whole post but you need a vacum sorce that sees vac & boost like your intake manifold.

and yah serching is a good Idea for well covered issues. Welcome to Honda-Tech

perhaps in other areas, not this one
you arn't familiar with pressure drop are you? or over speeding a turbo?

turbos, wastegates, BOV's...this is what WE do, your engineer buddy does not

 

I am familiar with pressure drop.
thats why I said there would be a small difference. 1-2 psi. Aboslute pressure is going to be whats going into the manifold.
Pressure drops through the intercooler and whatnot, so even though you may be controlling the boost to 8 psi before the intercooler, it may lose some pressure before it goes into the tb. Thats why you need to get the absolute pressure(the pressure the intake manifold actually sees).

Maybe my logic is completely retarded, as well as the posters in like 20+ threads I just read, but that's how I see it.

are there any tuners or someone who could come in and explain it to me if I'm wrong?

And TiAL, i'm not insulting you in anyway, so why are you insulting me or my friends father? He has been a car guy all of his life, I think he knows what hes talking about.

So youre saying that all the people in all threads I read were wrong? I mustve seen around 10 threads that said it was okay to t it into the brake booster or fpr.

tapping into the compressor will make the boost vary depending on the outside temperature.
Colder air is densor,

 

connect the vaccum from the wastegate to the intercooler piping, the side that cherges back into the intercooler

 

Hmmm so some of you are saying that it bad to use a source that have vaccum/boost? Anything pre-throttle body is definitely wont have any vaccum but how would this be better? i ran my wastegate vaccum and all other vacuum off my vacuum manifold which is tapped of the brake booster line(will have vacuum and boost pressure)

Thats exactly what I'm saying. There are a lot of people who run it to a vacuum manifold or t it into somewhere along the way.
There is nothing wrong with this method.

It's a turbo kit, I would assume, ebcause he said the turob that came in the kit didnt have a tap for a vacuum hose, so what kind of company would send you an untapped turbo if that;s the only way to do it?

I gave my suggestion because its the easiest way possible, he probably doesnt want to wait to get stuff in the mail froma company.

 

According to previous posted, the wastegate only reponse to a pressure only. So it wouldnt do anything at all when it sees vacuum, so i dont see how it would *hurt* using a source that have vacuum unless it bad for the wastegate and i dont see how it would be bad.

As for TiAL, as a distrubutor it would be better to educated the mass of your product if they are misinformed instead of posting phrase as i hope you're joking etc... but that just my opinion, i hope the people that know the product best is the maker.

 

The compressor is going to be your best bet. The wastegate is controlling the boost in your system, so getting a reading from the point that you want to control is smarter than using anything else. Using the brake booster is probably not the most intelligent way to control the boost in your system. If I were you I wouldn't just read online content-instead go to a book store and read some published information.

As far as your friend's father....did you let him know that the wastegate is controlling the boost in your system? If he is an engineer I'm sure that he wouldn't tell you to "T" off of the brake booster.

My 2 cents.

There is nothing wrong T-ing of the brake booster line, it the biggest source of vacuum in the car. If im not mistaken, most people use the brake booster line for their vacuum manifold that including myself.

 

Who is "most people"?

 

I welded in a barbed fitting to the piping coming off the turbo instead of taping the turbo itself... in previous years i have ran it from the intake manifold, but i had slight boost creep... coulda been anything though

thats the whole point of tapping it from the manifold, post throttle body. if i buy a 1 bar spring, i want to see 1 bar in my intake manifold not 13.3psi after pressure drop through my intercooler.

and for reference i have mine tapped off the compressor housing because my EBC directions state thats where it needs to be so i do have experience with both ways.

Thank you for helping me clear that up,
I appreciate it.
