I installed the new 20g on my car frinday and wanted to run the nopi event this weekend in west palm beach Flroida so first pass I ran 13.544@103.49 I said wats up car feels slow second pass turned boost up and removed some fuel and ran 13.069@99.35 boost hits a 26psi then falls to 17psi by redline I definetly have a leak or the wastgate acuator is not holding boost. I think this turbo makes good power I just wish I had time to dial it in before the event. How can you tell if your bov is leaking?

 

Thats one looooooooong sentence you wrote.

This is too vague because you didn't give us enough details.
What octane?
Tuning with wideband?
Why did you remove fuel when you raised the boost? A/F ratio?
Have you done a compression check?

 

That must be one big leak. Even with only 17 psi you should be trapping better than that. Do a pressure test on the system and check your EMS logs to see what's up. I don't think your BOV could cause this unless it's installed completely wrong.

 

will do I will replace the bov and pressure test and go back to the track on friday to retest

 

93 octane a/f was 12.2 then goes to 11.4 by redline

I removed fuel because it is my understanding that the boost compension tabel will add more fuel to scale.

good idea I will check it ..

 

Do you do all of the tuning yourself on the AEM EMS? You're running slower than a stock 05 currently, so I would imagine it's all in the tuning...

 

I am runing on my old map from a different turbo and was tuning at the track when the car would not hold boost.

 

Whats goin on man! You just keep changing and updating parts on your car! How has everything been? Also what happened to the bigger turbo?

 

yea I am trying different turbos to see which one I like best it seems you can NOT have your cake and eat it also I really want the best pump gas set up. I still have the br580 kit in the garage. good to hear from you.

 

Somthing is def wrong, those MPH's are horrible.

 

I think you should hook up your br580 kit and sell me that crappy 20g for cheap

 

if I do not like the turbo I might take you up on that offer. I was thinking of a gt3071r if the 20g does not work. I am trying to fix the bov tommorrow.

 

If it's the clipped 20g version from BR for cheap I like that as well

 

This is a useless thread. I wouldn't even have posted this unless the car was running right.

 

Man.. your car is running horrible. I think you have more than just a leak issue, you are boosting 26PSI but can even trap 100MPH with all the mods?
