GFB?s DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to "pilot actuation" to ensure better performance on stock or modified engines. , Furthermore, these...

The factory BPV (bypass valve) has a couple of key shortcomings in construction and operation. First of all, tuned engines running high boost also produce a lot of heat in the charge air. Because the BPV is situated right on the compressor, it is...

These engines come from the factory with no diverter valve of any kind, resulting in turbo compressor surge every time the throttle is closed after boosting., , The intake is acoustically tuned to surpress the fluttering sound of compressor surge, it...
