Lost Turbo Pressure! Durametric Log - Comments Please
After the Intake Plenum bendable tubing upgrade my 996TT only run 0.7BAR (before upgrade 1.2/1.3 BAR - Billets K16....)
https://www.6speedonline.com/forums/...sure-help.html
Today log 3º and 4º gear with durametric.
This time the engine cut power when the boost hit 0.7 BAR (3 gear).
Please can you see the log and try to detect a possible problem?
Thanks,
VS

The problems are resolved and the car is running like a beast.
After another inspection I fount the problems:
1. The vacuum tube that passes beneath the F hose and is connected to a check valve is disconnected. Is difficult to see because the DV and F hose.
2. The intercoolers hose (from intercooler to Ypipe) is not completely connected. !Strange! I did a leak test and didn´t detect this leak! The left and right hoses are connected and apparently OK, but after remove the hoses and connect only the metal connecter I saw that the retainer spring was not completely closed. Consequently, under full boost one side of the hose get up and the pressure was gone. My silicone hoses and connectors are from AP, I think the connectors are not 100% compatible with 997.2 GT2 RS intercoolers.
How to resolve? I use a clamp to close completely the retainer spring.
After these correction the car did quickly 1.1 BAR, but in third gear the engine cut the power!!!! I had another problem to resolve!!!!
3. I decided to verify the wastegates setup. The problem was here…. I setup each wastegate with 2 full turns on the nuts. Although the waste gates springs had the same nuts turn, I verified that one is start open at 0.8 BAR and the other at 1.1 BAR. This difference caused a engine cut.
How to resolve? With a hand pump I setup the waste gate to start open at 13 PSI
Now the car is running strong and without problems.
