no boost, what's wrong?
 

hello everybody.
i drove the car around tonight and from the second i started it till i turned it off i didn't felt the boost at all.
there wasn't any unusual sounds

the gauge shows 8psi's but its barley moving.

i checked for blown charge pipes but i didn't found anything,

the setup is:
log manifold
volvo 760 turbo
turbonatics wg
2" charge pipes
2"dp
apexi twin chamber bov
smic
safc and 450's
stock fpr


what could it be?

leaking bov ?

turbo?

so wait, the gauge reads 8 pounds, but you dont "feel" the boost, how much boost are you shooting for and how big is the turbo?

Re: no boost, what's wrong?
 

What the hell does that have to do with anything^^?

Is the guage creeping up to 8 like it normally would? I would mayeb check the bov or even the wastegate for possible leaks. That still wouldn't completely explain your gauge reading 8 psi but it could explain lack of boost. Maybe your gauge is messed up.

are you stupid, turbo size has everything to do with it, especially if a turbo is out of its efficiency range, there was a thread awhile ago were a guy was running to low of boost on to big of a turbo and didnt make any power at all :1

dont fight guys... lol

i raised up the boost abit and its fine now....:S

i think this wg has problam holding small amounts of boost.
