eBG76 Electronic Boostgate 76 Charge Air Valve The Turbosmart BoostGate 76 is an electronically controlled butterfly-style valve designed for charge pipe boost control. It is manufactured from Billet Aluminum for reduced mass and features the kind of control and flow you expect from the StraightGate series of Turbosmart products. Unlike a traditional external wastegate, which bypasses gas around the turbine housing aiming to reduce turbocharger shaft speed and effectively, boost levelsCharge Air control is a controlled bleed of the compressed air on the cold side of the turbocharger system. Mounted to the charge pipe, the BoostGate 76 can be used to modulate this air flow directly, rather than the indirect method of traditional control. Charge-Air Control is specifically suited to applications such as drag racing where turbocharger specifications have already been optimized, and the turbine housing is not the limiting performance factor. The BoostGate 76 is a zero offset butterfly-s
