do you guys at all think it could be the intercooler? possibly a leak somewhere in the intercooler?

Re: terrible boost leak. need help
 

maybe. fill the bathtub up with water and plug the ends and put the intercooler under water and see if you see any bubbles

Re: terrible boost leak. need help
 

good idea. i'm also beginning to think that it might be the wastegate. maybe the wastegate flap is either chipped or cracked, the only thing that i could think of that would only allow 1 lb of boost

try the soap and water test and take couplings off spray hairspray on them put them back on that fixed my boost leak

Re: terrible boost leak. need help
 

so the boost leak isn't as bad as i thought. i hit 6.5 lbs yesterday in 2nd gear at 5400 rpms, but that's the fastest i really drove it. i'm going to go out and cruise around today, see how much boost i can make. maybe the wastegate got stuck open, and then it repaired itself? we'll see what happens after today

Re: terrible boost leak. need help
 

is your wastegate closed shut really tight? You should be making full boost around 3k.

Re: terrible boost leak. need help
 

yea i know, that's what i need to check once i get the turbo off

Re: terrible boost leak. need help
 

that happened to me before, but it was stuck open because the flapper got stuck on the o2 housing when i bolted it up. felt hella dumb lol.

Re: terrible boost leak. need help
 

so i am officially confused, since today i hit 7.5 lbs, but couldnt hit that boost level at all after that

Re: terrible boost leak. need help
 

maybe the waste gate is getting stuck. If u boost that high and not at all after that then its probably not a constant leak (like a hole or somehting like that) so it would go to the component responsible for regulating the pressure. WG.
