Dumping the pressure close to the TB doesnt dump any of the pressure on the other side of the system near the turbo so there for, its all going to go into the compressor and stall the fan slightly etc… but if its as close to the turbo as possible then it will dump/vent all the pressure on that side instead of it bouncing back into the turbo… --- _[View the full topic](https://forums.speedlife.net/t/intercooler-question/106996)._
