I went to my shop today they were installing my truboost.. they said they had to tap into the turbo to install it does that make any sense to anyone? i have the dezod s1 kit and hes like the turbo didnt come tapped or something..
i thought the control solenoid just goes inbetween the vacuum and the wastegate connection??

what am i missing here

 

Interesting....

You can source vacuum from the compressor side (same as side of wg) but you still need to tap into the top of the wg to manipulate boost.

so what ur saying is they didnt have to do that?

so tell me what they should have done to avoid doing it so i can bring it up :D cuz they charged me more money to do so

 

bump anyone got a clue?

 

^^ yeah you can do that on the compressor side as what todd said! no need to do it on the turbo though, you can still get a good reading from another vacuum source like your brake booster or throttle body.. I think they are following the instruction on the truboost, some turbo have ports compressor for boost reading..

make sure they tap it right or in a good location..

 

hmm.. i hope they didnt do this yet so i can tell them they can just tap into the compressor side.. ;/ either way it will work fine correct?

 

the only way to do it is the compressor side? lol, if they know what they are doing they should only tap on the compressor side, its where the turbo build boost that goes into the intake manifold/vacumm source

 

well he wanted to tap into the turbo..

 

I tapped mine in the compressor side, I figured the longer the vac line the more chance of a leak which you don't want on your wastegate.

 

compressor side as in ON the turbo? im lost someone help me out.

 

You can see the vac line go from the wastegate to the compressor side

 

so ur turbo was already tapped? mine isnt..

 

then tap into the pipe right at the turbo compressor outlet.

 

i think they already took the turbo off to get it tapped.. they coulda just got a source from the throttle body to make it easier.. gah..

 

^^ he tapped it right on the compressor outlet..

in my opinion/preference, i want to use/ tap a vacuum source closest to the manifold as much as possible (like brake booster, throttle body) that way its the closest boost reading that is actually forcing air into the cylinder.. if you get leaks after the tap on the turbo compressor (like on the couplers,intercooler,bov, pipes) then your actually manifold pressure might be slightly lesser than your turbo compressor reading

 

Most compressor housings have a spot cast into them for the "tap".

But your shop didn't need to do this.....

Granted its their decision but it wasn't necessary to make the controller work.

The wg has two ports for a reason

ya they tapped into an intercooler piping for it... idk why..
anyway does the TRUBOOST come so it can read boost aswell as be a controller .. there trying to tell me that i needed to by an extra wire or harness thingy so it would read boost.. my main reasoning on buying it was to replace the boost gauge..

 

tapping intercooler pipe will do too.. and yeah truboost will be boost gauge too, no extra harness lol

 

what an idiot.. im so sick of this place

 

lol good decision taking your car out of that shop.. its good you didnt trust them completely
