Upgrade Your Heavy-Duty Truck with a VGT Conversion
Unlock the Potential of Your Turbocharger with a VGT Conversion
Variable-Geometry Turbochargers (VGTs) are engineered to optimize the aspect ratio (A:R) in response to your vehicle's changing speed. This design results in minimal lag, enhanced boost at low speeds, and maximum efficiency at higher engine speeds. However, VGTs may present certain challenges over time. By upgrading your Cummins 871 or Detroit Series 60 with a VGT conversion from Big Rig Power, we can not only improve your engine's performance and reliability but also reduce the risk of engine damage caused by turbo failure.
Challenges presented by vgts
As previously mentioned, although VGTs are designed to optimize performance and enhance fuel efficiency, they do have some challenges associated with them:
Carbon Deposits:
High temperatures and pressures in the exhaust gas make VGTs susceptible to carbon deposits. Over time, these deposits may impede the movement of the turbine vanes, leading to decreased turbocharger efficiency and impaired engine performance.
Vane Sticking:
Turbine vanes in a VGT can occasionally stick or fail to move freely due to contamination, carbon buildup, or mechanical issues. This can result in the vanes becoming stuck in a single position, leading to inadequate boost control and reduced power output.
VGT Actuator Failure:
The actuator in charge of controlling the position of the turbine vanes may face failures. These can arise from issues like electrical malfunctions, sensor failures, or mechanical problems. Actuator failure can cause improper vane positioning, resulting in suboptimal boost pressure and diminished engine performance.
Turbine Lag:
Some variable-geometry turbochargers, particularly older designs, can experience turbo lag. Turbo lag is the delay in the turbocharger's response to changes in engine load, which can cause a slow throttle response. While advances in VGT technology have alleviated this issue to a certain degree, it can still be a concern in specific applications.
Complexity and Cost:
VGTs are more intricate and costly than their fixed-geometry counterparts. The inclusion of movable vanes and actuators adds to the overall system complexity and may potentially result in higher maintenance and repair costs.
The VGT Conversion Solution
Prevent potential engine damage and optimize performance by replacing the VGT with a recommended aftermarket turbocharger. This durable and reliable alternative provides a more efficient method of creating boost.
