recently i just changed my Turbo elbow, to a full 3" one and the only things i took off are upper inter cooler pipe, heat shield. before when i had the non restrictive one it use to boost up to 6-7PSI but now when i finished installing the new turbo elbow after 3krpm it dosent blow the bov. and i feel it slower plus it shows 0psi or 1-2 psi.
iv double checked everything, no poped off hoses(hard pipe) ect.

i think it might be boost leak but i was wondering how to do that test. where do i block off things?
i have boost cut as well.


any suggestions?

This is *not* an appropriate response. If you're going to play the part of the search police on SM, you need to explain how to search, and provide search terms that you have already vetted.

Otherwise, your post is worse than useless.

This isn't exactly helpful. :nono:

Roadboy- there's a DIY for making a boost leak tester in the Articles section:
http://www.supramania.com/forums/showthread.php?t=19718&highlight=boost+leak+tester

You can try that. Otherwise, go over all intake piping with a fine tooth comb, concentrate on the charge pipe right off the bottom of the turbo, and the coupler at the throttlebody. They're generally the ones that crack most often.

How to check a boost leak something WELL covered probably once a month. He's been a member since Jan 2008 with over 100 posts. This should not be new him.

It definitely sounds like you have a boost leak, as it has been pointed out. With your non-restrictive elbow, you might have made enough boost to spring a leak somewhere. The turbo outlet hose would be my first suspect, because it gets very hot, and chances are it's the original one. This hose sometimes springs a leak on the hidden side, or it's not fully seated on the turbo itself. Don't forget to double check the rest of the hoses and all the intercooling system clamps, too.

siliconeintakes.com has boost leak testers, that is if the diy thread does not satisfy you. they are like 30 bones i believe but weigh out your options.

Whether it's new to him or not isn't the issue. Whether he can search or not also isn't the issue.

Take two scenarios.
1. Question is asked, and answered using your method.
2. Question is asked, and answered using my method.

Now, fast forward a couple years, with this happening quite a few times over the course of time, as we all know is going to happen.

Scenario #1.
Someone needs to know the same information, logs in and searches for it. The search returns dozens of threads - and they are all USELESS, because the contents are the same - "Search, noob." User searches again, with different terms, finding about the same results with each. The actual answer has been diluted to the point that they need to read hundreds of posts to find the information they need. The server running Supramania becomes overloaded with people searching and finding nothing. The staff puts a limit on searches, making you wait a few minutes between searches, or disables it entirely to make the rest of the site respond in a timely manner. Sound familiar?

Scenario #2.
Someone needs to know the same information, logs in and searches for it. The search returns dozens of threads - and they all either have the answer, or instructions on how to find the answer. No extra load, no knowledge dilution, everyone wins.

Now, would you still like to pick option #1?

I made my own as well, offered the site cause along with that they also have other useful things relating to turbos.

I went through hell making mine, took awhile to find the correct size coupler, they just didnt have the right ones in stock

While I see your point Grim, I feel we both make valid ones. You are the admin, so obviously I can't win right or wrong as you have final say. BUT, one of the top 'rules', or maybe in better words, understandings, is to search first before posting. Now if he had made a comment along the lines of "I searched for a long time but found nothing helpful" etc, I would completely understand as i've used the feature countless times and have seen the results but he didn't. In my experience with forums (overall), most people will mention this fact, as they are frustrated and tired of dead-ends and just looking for some sympathy for answers. Maybe he did, maybe he didn't, I just went with my gut instinct on this one with no. Not to mention, if you can't find something good using SM's search, try google's.

Either way, I feel this conversation is over. I'll avoid responses like before and just leave the thread to die like many do with obvious, or well covered issues.

On a side note. If I saw he was new or even relatively new i'd have been much more helpful. Sorry OP for a pointless post, but, remember, google/search button is your friend. BTW, hit Home Depot for your tester parts and use google to find out what you need.

Ha! If being an admin makes me automatically right, will someone please tell my wife? Seriously though, I don't win debates anywhere, least of all here, by relying on my 'rank'. Among other things, consider that I didn't start out as an admin here - at one time I was a regular user, just like most of us.

Leaving the thread alone is a good option - teaching the OP how to search is a better one, but there are plenty of people who are willing to help with that. The frustration level that comes with answering the same questions over and over will mean the group of people willing to deal with it is always changing, and this is ok.

be advised that when you put on a larger elbow you increased the flow the turbo produces down your exaust if your cataletyc converter is old it may be holding your turbo back i only say this because it happened to me and it did turn out to be the converter just thought you should know would hate for you to be searching for a boost leak and it be the converter the whole time like i did well good luck bro.
