Fresh new build running & sounding great but not getting any boost after test drive. This is on a stock ecu stage 3 build 1100whp on E85 waste gate and all pipes look good no boost leaks visually..

 

What are your BOV's set to? Have you done a leak test?

 

Yes leak down test has been done...

 

What PSI did you pressurize it to and how long did you hold it there?
Boost leaks are a huge pita to track down. My problem turned out to be the diverter valves.
Do you hear the turbos spooling when driving?

 

No boost spooling...

 

Just my opinion but I would venture to say your builder/tuner would be the first one to reach out to. Surely that build just cost you a pretty penny. In terms of customer service they should be more than willing to help you sort this out as I'm sure there are non-stock components that only they are familiar with. Good luck, sounds like one hell of a ride.

 

Appreciate the feedback 🙏

 

^This. With that kind of power and mods, only your tuner/builder would be able to effectively troubleshoot this.

No boost would be pretty high up in the list of things you would want to check out on a build like this, and I would imagine any reputable engine builder would have done at least this basic level of testing.

1100 whp on a stock ECU sounds quite interesting. Do you have any dyno sheets and a mod list?

 

had similar issue and it was the charge pipes, as others have mentioned leak test is a decent starting point.

 

Thanks for the help...

 

1. Boost leak test - you need to know the air circuit is solid
2. Pull some measurements with a reader (demand boost/actual boost, maybe some other turbo related items)

Did you ever have boost? If not, as others have said, you need to get with whoever sold you the stuff and find out what's not working.

While the turbo loop isn't complex, everything has to be working in order to generate any boost. If you replaced the stock stuff, and you had boost before the replacements, then you have the answer to the question, "What changed?" - In this case many things, and you should verify each one is working, from the tune, to the air loop, to the components.
