SO I think I have a boost leak, how do I figure out where it is coming from??


ALSO! I launched my car today, and it didnt go very fast, but I ran through all of the gears still, and it just didnt go fast, it confused me very much..

Sorry if I cant give everyone a lot of information, I am confused, i think its just a bad boost leak but idk how to fix it or find out where I am leaking air

 

Get a book leak tester. Mellon Racing sells them and they are like $100. As far as not going fast enough, maybe you're expecting too much or cant drive. Hope this helps

 

Search "boost leak" and you will learn a lot. I just did a boost leak check on my car last week for the first time: https://www.evolutionm.net/forums/ev...k-results.html

 

What he said.

There are a bunch of threads. You can make one for really cheap. I made one myself and I'm going to be testing once I get a chance.

 

First off op you need to SEARCH! first a simple keyword of "boost leak" will tell you all you need to know.

Forget mellon for a $100 for a leak tester thats ridiclous, BUY THIS if you want to save the hassle or dont know how or make one yourself. This tester is quality worked VERY well for me and helped me find a bunch of leaks. HIGHLY RECCOMMENDED

They also make ones for 4inch inlets and so on for guys running bigger turbos.

 

Honestly im not trying to knock Mellon Racing I have alot of respect for them since they help out alot of people including myself. Its obvious the op does not have the knowledge enough to build one himself so I would get the boostleak tester and fine and air compressor do this when the car is cold or your going to burn yourself.

Then attach the air compressor to the boostleak tester and apply air through the valvestem but remember make sure that boostleak tester is equiped with t-bolt clamps or its gonna pop off the clamps and that **** will probably hurt. Then while its on and air is applied in the system listen for slight leaks or hissing sounds coming from the piping. If there are leaks in the system if the couplers are damaged replace them. The stock clamps dont work so try to get tbolt clamps if you can help it.

 

+1 ^^

Mellon Racing is good stuff but the $30 eBay tester works just fine. I did a boost leak test with one similiar to the one for sale above. Worked perfectly. Yes, when it arrived, I realized I could have made one myself but $30 was a small price to not have too.

 

Or just build a home depot racing one on the cheap. Do some homework OP will make your life easier. Lots of help on here. Doing a boost leak test can be trickey if you dont understand what you are looking for

 

make one for 15$ and find the issue. I made one from parts at Lowe's for about that price and people have done it much cheaper. If it makes the car that terrible i would think that a coupler has completly come off or the FPR hose has came off. Go to the plumping section of Lowe's, measure your intake pipe inside diameter and find a coupler that is close, then just find the combination that will close off the coupler (reducer, etc), pvc glue, and a valve them to intall or an air hose coupler however you want to do it.

 

I made one myself execpt the gauge didnt work, oh well I ended up using my Boost Gauge to monitor pressure and found the leak, EGR... so I am pitching the EGR

 

Honestly you dont need a guage just get a boostguage and monitor that imo and watch the pressure

 

so wait you think you have a boost leak because your car isnt performing at 100% and instead of fixing it you say screw it, and launch it???? i can see it now 'F/S Clean Evo never been abused.........'

 

I'm not sure where the 100 dollar price came from, ours is 59.00 always has been http://www.mellonracing.com/index.ph...roducts_id=840

 

theres a how to on how to make one for under 10 bucks. and i agree with warstang. if your car is having issues you shouldnt be launching it.
