wastegate question
 
what would happen there was no line from the wastegate to the compressor?

Re: wastegate question
 
Your wastegate wouldn't open, you would overboost, then you would probably blow your motor.

Re: wastegate question
 
you will blown your engine cyz wg never will open.. why? becuase there are not boost to spring of wg..

haha sorry brother.. :-[

i try again ;D

you will your engine because the wastegate never will open. Why? because there are not boost for to move the spring of the wastegate.. right? :D

Walter, the WG needs to sense the pressure to have it operate and open at the desired PSI. Without a vaccum source the WG doesn't read anything and will never open. You need a vaccum source to the WG from somewhere that way when you build boost it WILL open at the desired PSI.

i dont know to explain good in english.. :'(. someone can give me class of english hahah..

but here i have a pic about it. (though it's in spanish ;D).

i did study this topic about turbos ago a long time so far ..i love the turbos haha , it's a puty that my enligsh is bad because there are a lot info about some stuff (about engine, camshaft,etc) in english.. but little by little i learn english more.. :y

it needs a boost reference, not vaccum. The only vaccum source you have during boost is your pre-turbo intake, and that will not open a wastegate.

walter, are you spanish? As I read your bad english, I was doing a russian accent in my head. lmao!

Ha, I know, but try explaining that too him. Hook up a vaccum line to the WG, Walter.

Hhahaha not, i'm peruvian but i live in Spain ;)..

about the vaccum source yes, the exaplain by samson be strange cuz he saids that the vaccum source will open WG haha..

Sorry for my english though i'm learning everyday :D

I'm sorry. B16CRXT was right in telling you his way then. :-\ It will read PSI and MMHG (vacuum) though now with boost in the lines. Those "vacuum" lines do have vacuum in them and show vacuum until boost is created and there is now pressure in the lines. Any vacuum source will work because when the car boosts there is no vacuum and now pressure in the lines instead. I'm trying my hardest buddy to help you, I really am.

Re: wastegate question
 
what I did was get a vaccum manifold from a guy on here named djfob. I put that manifold on teh brake booster line, and ran a good size line from it to the wastegate. But I had a turboxs dsmbc on that line as well to switch from low to high boost.

no problema. thank you for youy help , i appreciate it brother. ;) ,where would it go connected the vaccum line? in above pics that i did put , only see a one line.. or only one line read the boost and vaccum?

samson 05-06-2006 12:32 PM

Re: wastegate question
 
Run a line from the WG nipple to the Turbo nipple which SHOULD be on the turbo outlet. That will work just fine.

The one line has vacuum in it at first then as boost is built the engine is pressurized. then the line that had vacuum in it a few seconds ago now is pressurized from boost building in the engine.

yep, you can do it this way too. But for accurate boost control, you should use a boost reference after teh intercooler. It's not entirely necesary, but you could be wanting to run 10psi, and only be running 8 or 9 once it gets past teh intercooler.

Walter 05-06-2006 07:51 PM

Re: wastegate question
 
mm , do you have some pic about this? i try find one but nothing.. only see WG with one nipple that it goes to manifold..

example.

i will continue searching..

B16CRXT 05-07-2006 07:35 PM

Re: wastegate question
 
putting it to the manifold will be fine, if you have enough open vaccum sources. I wouldnt let it share a small line with something else thoug. That's why I got the vaccummanifold....to split the brake booster line and give me a large source to share on.

Hmm, I understand what you're saying now. I didn't know you lost a psi or 2 through the IC like that. My gauge is off by about 2psi anyway from comparing it to the dyno. I might re-route my lines straight up to the empty source on the intake mani.
