I can feel it stop maken power after it hits 7psi. bad gauge? got any ideas?Maybe kinked or crimped some how??

 

whats your setup?

 

stock motor for now. but for turbo:

herms fab log mani
turbonetics t3/t4oe 60 trim
38mm tial wg
open dp
450 injectors.
crome tunnin

thats the gist of it.

 

anyone?

 

i sprayed some wd40 in the WG an Bov. I think the BOv is also sticking. but i took it for a quick drive. i couldnt get up on but it seems okay. maybe because of the opem Wg an the heat shield i have right in front of it causen it to stick.anyone heard of this before?

 

well i went an looked at the whole setup. i think maybe my WG is sticking because i dont have a pipe an i have a heat shield about 2-3inchs from it. so when it open up it doesnt have a good place to vent causen it get some type of carbon build of. em i fetching here?

i sprayed some wd40 in it along with the BOV. I can accully her the bov now..i couldnt before. so i took it some more. 5k it was a 10 psi. nowi think thats about right considering the open dp. but it sure didnt get to 15psi. but it is about 40 degrees colder. would that play a factor. i would think it would be more boost if it was colder. i dont know.

 

up

 

don't know but i'll bump
i am in mid build and would like to know

 

FIXED!!!!YESSSSS...

Well i went to fo look at the wg flange an make sure i had the right bolts. well moved the vac hose connected to the turbo to the wg..well this is what i found :eek



easy fix took it for a spin..7psi no prob.

 

 

thanks..im just surpised the motor held 15psi a few times..crazy.
