Default Boost drop after 5000 rpm - 09-11-2021, 02:11 PM

Good day! Please help me to disassemble the log, when dialing 5000 rpm under the hood you can hear a crackle of 2 seconds "trrr", and then the boost falls. Turbines are hybrids Turbosystems, the car does not eat oil, does not smoke, the mileage on new turbines is 8000 kilometers

If you have silicone inlets, check and make sure they are not collapsing under boost.
Especially the newer VRSF.

Agreed.... you can see the boost drop and WGDC increase. Collapsing inlets, boost leak, intake filter issue, or ?

I pressurized the system according to the instructions from the forum, lost several small leaks, installed new solenoids, but the result is the same. The inlet inlets examined them intact, I assume that the rear one sucks, what could be the reason, the poor quality of the inlets? The new K&N filter is in its regular place.

If the inlet is collapsing, that's kind of hard to diagnose/see since it only happens at high boost.

Nice job...you can definitely see it get sucked in!
