Engines that make no vacuum — diesels in particular — can't trigger one. The HKS Super SQV4D solves this with a Boost Drive Controller (BDC) and solenoid valve that operate the SQV using positive boost pressure instead, so it works on diesel engines as well as conventional turbo cars.\u003c\/p\u003e\n\u003cp\u003eThe controller gives you control over how it behaves. An on\/off switch turns the SQV function on or off at any time, a trigger switch fires the valve on demand, and two adjusters set the accelerator point at which the SQV activates and how long it stays open. Indicator lights show when the system is in standby and when the valve is operating.\u003c\/p\u003e\n\u003cp\u003eThis is the universal kit. Fitting it to a vehicle also needs a flange, pipe and hoses to suit, which are not included.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Super SQV IV sequential blow-off valve with HKS Boost Drive Controller\u003c\/li\u003e\n\u003cli\u003eOperation: positive boost pressure via solenoid valve — no manifold vacuum required\u003c\/li\u003e\n\u003cli\u003eWorks on diesel engines and conventional turbocharged engines\u003c\/li\u003e\n\u003cli\u003eController: on\/off switch, on-demand trigger switch, activation-point adjuster, operation-duration adjuster\u003c\/li\u003e\n\u003cli\u003eStatus indicators: green (standby off), red (standby), trigger lamp (valve operating)\u003c\/li\u003e\n\u003cli\u003eMade in Japan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSQV unit\u003c\/li\u003e\n\u003cli\u003eBoost Drive Controller\u003c\/li\u003e\n\u003cli\u003eSolenoid valve\u003c\/li\u003e\n\u003cli\u003eSmall fitting parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired extras:\u003c\/strong\u003e an SQV mounting flange, charge pipe and hoses to suit your vehicle — HKS notes these are not supplied and must be sourced before installation.
