Boost By Gear Dual Solenoid Expansion Kit

This kit allows users to expand their existing boost by gear harness, allowing it to accept 2 individual solenoids. Created to solve a demand for turbo setups that run 2 solenoid valves due to the application having 2 individual wastegates. This allows greater control and accuracy splitting the demand between 2 valves instead of 1 single valve working both wastegates. The efficiency is much better using this method and users report greater boost stability and higher adjustment ranges.

The kit is designed to work as a plug and play unit in conjunction with our standard 3 port BBG kit. This means you will need an original BBG kit to make this a working component. We include the expansion harness, additional 3 port solenoid valve, a set of push lock fittings strictly for attaching the second solenoid, and 15 feet of premium DOT rated air line.
