Boost leak!

Re: Wierd boost problem
 

I'm not 100% sure, looks like a HMT downpipe mated to a crappy ass catback.

Thats the first thing that came to mind but I cant find the leaks, this thing is a mess though, all rigged up.

My friend had the same problem, he told me the same thing; until I want and took a look at it my self. Rev it up with soapy water.

Re: Wierd boost problem
 

Good idea,

I got a coupple PVC ends with holes drilled in em, one has a pressure guage, the other had an adapter for a hand pump, I stick one on each end of the chargepiping. I'll prolly try both tomorrow.

I had a problem like this before The valve on my wastegate was just chilling open because the lock nuts fell off.
---- pissed me off bad.


Im gonna go with fire ring on the waste gate or boost leak or MUFFLER BERRING.
BTW Im ------- wasted. ;D

Re: Wierd boost problem
 

I held my hand over the dumptube while bouncing off the launch control, we got 3psi, and the wg was not open or leaking, I took the dumptube off to doubble check at watched, same thing 3psi but no piston movement. I'm going back over there now to take a better look.

Re: Wierd boost problem
 

Thats has to be a boost leak in the piping!!!

Re: Wierd boost problem
 

yup sounds like a muffler bearing to me.

i think its a combo between clogged cat/shitty exhaust and a boost leak somewhere.

the compressor houseing on that mad tite CDM chingcong autoshit turbo probably came halfway unglued :1

Re: Wierd boost problem *UPDATE* No charge leaks.
 

I pressurized the entire charge piping from end to end, found the BOV was leaking slightly, and 1 couppler had a small leak, Fixed the leaks and went for a drive. The boost raised from 2.9psi yesterday to a whooping 3.7psi today. WTF?

Exhaust is 2.5in. downpipe to a 2.5in. catback, BUT the cat that's in there is a STOCK CAT, wtf? anyway do you seriously think that the stock cat would be restricting the exhaust that much? well the car went to the body shop, it will be back friday and I guess I'll find out.
