ive been looking around and havnt got any answer to my leak

well here it is , when i start the car i can hear a loud air leak from the IM area
but i cant able to fine where it is , i think its under the IM
and when i start rolling the air leaking gets louder and after boost come in
it covers up the noies. but im sure its leaking real bad

my setup is to boost 9psi
but right now it only boost up to 0.4bar

mods are PFC. apexi intake. down pipe .greedy profec B boost controler

anyone having the same thing happening ?

i checked most of my couplers then they all in good shape.

thanks

 

Probably a baked and cracked vac hose. Take the "IM" off and look.


later

 

im gonna do that tomrrow. but befor doing it i whould like to narrow it down as good as i can

and im also hearing small turbo surge flutter from 0-3k rpm coming from the driver side, it doesnt do that befor,i have a apexi bov
also the air leak sound is louder on the driver side aswell

 

Check all your intercooler hoses---- the black ribbed ones crack around the circumference of the ribs.

 

hmm i checked all couplers.
but no good stil cant find it

if its a vacuum hose that poped off
whats the symptoms?

whats the symptoms for cracked coupler ?

my car idles fine befor(1k) after i mess with the crossover / intercooler
its starting to idle real low(700-900 )and rough but after it warms up it goes back to 1k


i can hear the air vent really loud while on the throttle
and turbo surging under 3k rpm

my boost only reach 0.40bar on both turbos

pattern is like 6-2-6

 

You have a boost leak

Check the coupler at the top of the 'Y' pipe connecting it to the cross-over pipe.

 

Yes, I agree. This is where mine was leaking when I bought my car. It is hard to see and can LOOK okay when it is not.
