CRAP! boost (woosh) no power.

CRAP! boost (woosh) no power.
ok today I took my car out for a test drive with the CAI however after about 10min of driving and about the 3rd time to boost I heard a loud shhhhhhhh noise comming from what sounded like right in front of me when boosting. So I figured maybe just a vac cap came off or a vac hose however it didn't mess with my idle so I then thought that maybe it was only when there was air passing threw it at boost..........hum......well sure enough I look under the hood at all the vac caps and hoses and all are in place and zip tied down. Well where to go from here. Is there any good way to find something like this??? All the ic hose clamps are tight and none are broken. Damn this sucks I hate this kind of leak.

check to be sure a hose didn't split or get cut on a sharp piece of metal or worn through by a pulley, etc. a split in a hose could hold vacuum so the idle would be decent and leak under boost, it would also not be visible easily to the eye, try squeezing the hoses to see if there is any cracks or splits.

that does sound grusome and I just installed the turbo on the car and there was very minimal side to side shaft play and no front to back play and turbo spun freely so I don't think the turbo is to blame and that wouldn't make that loud shhhhhh sound when the turbo kicks in.

I just put this turbo on like 100 miles ago guys it's not that! the shhhhhhhhh noise is comming from a hose somewhere right infront of me in the engine compartment. I can hear it. It does build plenty of boost just escapes out of whatever vac hose or seal around pov that is busted or leaking.
#16
yeah I'm going to check again. I have a pov right there as well so I'm going to make sure the sealant on that thing isn't shot as well. I only have like 3 vac lines left in the hole car so it can't be that hard to find I'm checking it tomorrow again for any split vac lines etc... After that I will post the results of the cai.

Check your gasketts..... My car is making a loud SHHHHHHHHHh sound when the turbo kicks in... I'm still makin 14PSI of boost, but i should be avle to make more with my turbo....... but something aint quite right... I think something is leaking somewhere...
Idle isn't always affected.... when my car was still stock... the damn bolt that goes THROUGH the UIM has worked loose and the car was idling fine... when i sprayed carb cleaner under the UIM... BINGO... died... the damn bolt broke when i tried to tighten it up too....

well I checked all the the vac caps and found that one had a slit in it so I replaced with a nice heavy duty one however this was not the problem so I took off my pov and made a gasket for it instead of just using rtv. I'm now waiting for the rtv to dry or cure however you say it and when it's done I will tighten it down all the way and take a drive and post the results both here and in the cai thread.

Just tried got finished with the pov gasket and rtv replacement and that didn't work either. Next I will do like some of you had said and remove the tid to find out if there is anything wrong with the turbo even thought I still don't think thats it because I can actually hear the pressure comming out of something! Grrrrr......

I'm wondering if the pov that came with this intercooler was not working and started working now??? it always starts around 7psi witch they have a 7 to 12lb spring and then a 13 to 18lb racing spring. Hum........ Does anyone have the hks pov???
#25
yeah I did disassemble it today to make a gasket for it and to add new rtv. I need an idea how to keep the pov closed so I can see if this is the problem. If I can some how keep it closed and no boost escapes I'll get a higher pressure spring. They come in 5-7psi 7-12psi and 12-18psi so I'm going to get the last one if this is the problem but don't want to spend the money if I don't have to .
