Default BOOST LEAK TEST?

Just wondering if its possible to check for a boost leak without using a air-compressor? I have one but im scared i might do something wrong by using it. I was also told i have to make sort of a suction inlet thing and all this other crap. Is it possible to check it with the car on and applying boost that way to find a leak? Im pretty sure there is one because stock gt run about 14-15psi and im only getting about 9-10psi max. Thanks for the help

Stock GT boosts 9-10 lbs so you are normal.

10-11psi at most and that'd be due to weather/altitude.

You do know you boost slightly less to achieve the same power at a colder temperature than that of a warmer temperature.

Yeah, if you do a search you'd find out how. I've explained it enough times myself

I do have a boost leak tester that, I was supposed to send to someone but I don't have their PM or anything. It's just a 3 or 4 ply silicone coupler; one end is open (for the turbo) and the other is sealed with a valve stem on it.

You'll need an air compressor with a regulator and filter (to keep moisture out). Connect the hose to the valve stem, run 20psi (not 1 psi more!) through the system with the key in the ON position and well, that's your boost leak test. The rest is self-explanatory.

Yea I was hoping there was another way without having to use a compressor. There no way to feel around by pressing the accelerator and forcing air out through with the turbo?

The td04lr turbo does pump out 14psi but that is only on the SRT 4 neon, our pt gts only push 8 to 9 lbs stock even tho the utilize the same turbo idl why Chrysler did that but they did anyway.

Give me your address then!

To the OP, harbor freight is your friend. You can pick up an air compressor for under $50 bucks either there or at Walmart even.
