Simple Variable Boost Control For cars With Turbochargers

摘要

Quite a few cars have turbochargers these days and these can provide even more performance if the turbo boost pressure is increased. However, you don't want permanently increased turbo boost because it increases wear on the engine, so you need a variable boost control, as presented here. This Variable Boost Control is a simple circuit to modify the factory boost levels. It was originally designed to suit a Subaru WRX, but it could be adapted to many other cars and four-wheel drive vehicles (FWDs) fitted with turbochargers. It employs a small PC board and requires only four wire connections to the car's electrical system.
