no boost?

[89s13silvia]

ok so first off all my lines were run by someone else so I'm not sure if thats causing it or now

but i doubt it

so i have defi guages and when i give it on the throttle the vacuum will decrease a bit but i won't make any boost

i have my lines hooked up like the following.

wastegate to bottom of profec a controller

top left of profec A to ic piping right before the i/ mani
top right t's off to the defi boost gauge sensor and to the end of the fuel rail

that t's off to the the bov and the intake mani itself

so there are 3 t's run off the one line

not sure if that could be why but all my ic piping seems to be connected tight so i'm not sure what else it could me

thanks

too many t's

tee off your fuel pressure to intake mani to the defi


mines like this.

same for profec (i run smae setup)
but the one thats off the profec tees from the wastgate to profec and to manifold
defi and fuel pressure same vacuum
and bov goes to greddy controller box inside and mani



thats how it is i think...

[89s13silvia]

so i have a t off the wsategate line? that goes to the mani?

i was told that the bov should go directly to the mani

so run a solid line form the fuel pressure to the defi boost guage?

you also won't make nearly any boost at idle if thats what you are trying to do

Theres a good chance the boost gauge works fine and so does the turbo and hes just revving the car in neutral

true that, you either rev the shit out of it to get alittle boost, or actually drive the thing and get the thing under load to build some boost.

hah thats right
w/o being in gear and driving
just reving you'll hit 0 vacuum
at idle will be negative
