Why is my car losing boost at about 4 1/2 - 5 rpm, all the way through 1st too 5th,
My turbo leeks. I hear a wooosh sound under the hood near the front of the drivers side.
I have very little mods cat-back exhaust, and turbo gauge.

I checked my bov and I dont think there is any cracks but it is stock plastic krap..
definitly going to be replaced.

can it be any thing else that would cause me to lose boost.
I also tightened all the hoses and clamps.

any help would be awsome!

thanks guys and gals

 

If it was the BOV u probally wouldnt hear it. well I didnt here mine all i knew is that i would hit like 19-20PSI then INSTANTLY drop to 16 and hold. I had an MBC on also. Might have a crack in the hose.

 

I checked all the hoses and I didn't see any cracks, and I just remembered that it doesn't do it in fith gear. my car only has about 5200 miles on it. and I know it wasn't like this before.

 

bump

 

does it spike to 19/20 and go down to about 15/16 after 4 1/2 rpms?? if so thats normal, stock boost taper, get a manual boost controller.

 

make sure your "ram air" style snorkel (thing that goes into the airbox) is clipped down to the frame.....i bet its sucking up to the hood

 

Thanks dude, I bet your right! I lost both of the plastic plugs that hold it down when I changed the air filter.
Why do you think this would cause this, and where can I get some more plugs?
Im going to go take a look and see if I can use some zip ties for now..

 

I was going to say the snorkel thing too. Do a search someone use something else and it worked fine.

 

Yup, you right, just to let every one know. Make sure your intake box is strapped down or you will have this problem
