Loosening chargepipe clamps can be a common issue on the Nissan GT-R, particularly if the car is modified or driven hard. The chargepipes are responsible for delivering compressed air from the turbos to the engine, and loose clamps can result in a loss of boost pressure and reduced engine performance.
To address this issue, it's important to make sure that the chargepipe clamps are tightened to the manufacturer's specifications. This may require the use of a torque wrench and the correct torque settings for the specific clamps in question.
In addition, some GT-R owners choose to upgrade their chargepipe clamps to aftermarket options that are designed to provide a more secure and reliable connection. Some popular options include T-bolt clamps or worm gear clamps, which are designed to provide a more secure and reliable seal compared to the factory clamps.
It's also a good idea to regularly inspect the chargepipe clamps for any signs of wear or damage, and to tighten them if they become loose. By taking proactive steps to address this issue, you can help ensure that your GT-R is running at peak performance and reduce the risk of more serious issues down the line.
