im loosing 2 pounds of boost. and i can hear what sounds like an exhaust leak from the fire wall inside the car, but cant hear it outside. it sounds like the intake manifold is leaking, has anyone had this problem, or any ideas of what else it mat be. its not the sharge piping i tightened it as tight as i could. thanks

 

well, it wouldn't be too hard to inspect your intake plumbing through the turbocharger and intercooler to the throttle body and intake manifold to find a leak.

also, check your vacuum lines for leaks.

 

its supercharged so theres only one charge pipe. i was just wondering if anyone has had a problem with the crappy plastic intake manifold leaking.

 

people put 400+ hp through that little crappy plastic mani dont think the trd has the bawls for that lol

 

Are you using the stock bypass valve? If you are that could be your leak right there.

Edit: I noticed your using the turbo xs byv. Maybe you have a vac leak where you tapped for the boost gauge?

 

nope i super glued it! itd ticking low on the back side of the motor. plastic manifolds are **** to cracking and warping i was just wondering if anyone has had this problem. to make sure it could be the manifold

 

ok... here is a question. Did you make any adjustments to the BPV? If it's not adjusted properly, I think it will lose boost. When I installed mine, I was only boosting at 5, while with the stock BPV it was 7. Take a look at that. I doubt its the "crappy intake manifold"

 

ok after trouble shooting for two hours. the dumbass who put my plugs in didnt tighten down the # 3 plug it was finger tight. one of my friends helped me put on the s/c i wasnt there when he put the plugs in. thanks for your help guys!
