Description
The DV+ for Toyota and Lexus turbo models!
GFB’S DV+ SOLUTION COULDN’T BE SIMPLER – KEEP WHAT WORKS AND REPLACE WHAT DOESN’T.
- Uses factory solenoid coil for seamless integration
- Replaces plastic valve parts with metal for reliability and strength – especially important on tuned engines
- Direct-fit replacement with GFB’s TMS benefits
- Exclusive “pilot-actuated” valve mechanism for rapid response at high boost
The solenoid coil itself from the factory-fitted valve is great- the ECU opens it faster than any pneumatic valve so why replace it? The weak point however, is the valve mechanism itself. GFB’s DV+ solves this problem by replacing the valve parts with an anodised billet aluminium housing, fitted with a brass piston machined to exacting tolerances.
The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve, or include a solenoid valve with the diverter. These approaches add unnecessary cost and additional parts.
GFB’s DV+ on the other hand is still the fastest responding and highest flowing diverter valve solution on the market. It’s also less expensive than the competition and comes with a lifetime warranty!
GET BETTER PERFORMANCE, FASTER BOOST RECOVERY AND DON’T PAY FOR WHAT YOU DON’T NEED!
The DV+ story: Better performance – more reliable
The current generation of Toyota and Lexus turbo engines uses an ECU controlled solenoid-type diverter valve which is common practice these days. However, even though these types of valves have been around since the mid 2000s, they still have significant reliability and performance shortcomings that the only the DV+ can solve.
Problem 1: Leaking
The factory diverter uses a piston that, owing to its moulded plastic design, cannot be effectively sealed. This results in leaks that are large enough to cause slow spool up and high RPM boost drop off.
The DV+ ensures your hard-earned boost gets to the engine by using a bonded silicone face seal and a precision piston-to-bore clearance and surface finish.
Problem 2: Reliability
In the factory diverter valve, the solenoid is required to move the piston through a large range of travel, which significantly weakens the magnetic force that the solenoid can apply to open the piston. This means a weak return spring must be used, leaving little headroom to accommodate increases in boost pressure or friction in the valve assembly without causing sticking and reliability problems.
These issues also exist in other aftermarket products that retain the factory solenoid and continue to direct-drive the piston over a long stroke.
The DV+ solves this issue by re-purposing the solenoid to control a short-stroke pilot valve for super-fast reaction time and higher actuation forces. Using the pilot valve, the DV+ uses boost pressure to open AND close the piston. This means the acting forces are directly proportional to boost pressure, and therefore the movement of the piston can respond accordingly. If boost is low, the piston only opens a small amount. If boost is high, it opens all the way. Once the solenoid turns off, the boost pressure then slams the piston shut. This way, the DV+ completely eliminates sticking as a result of friction and weak solenoid forces, and blowing open at high boost.
The DV+ is the original performance diverter solution, offering faster response, better performance, and unrivaled reliability with a lifetime warranty.
