GFB is proud to introduce the latest addition to their DV+ lineup: a direct-fit performance diverter solution designed for GM vehicles equipped with the 2.0 LTG engine.
You might be wondering, "Why replace a solenoid coil that works perfectly in the factory-fitted diverter?" Well, the answer lies in the valve mechanism itself. GFB's DV+ tackles this problem head-on by overhauling the valve components, replacing them with a meticulously crafted anodized billet aluminum housing, complete with a precision-engineered brass piston.
But the improvements don't stop there. In the DV+ assembly, the solenoid no longer directly operates the piston's movement. Instead, it controls the piston's action using boost pressure—a technique known as pilot operation. This amplifies the actuation forces within the valve, enhancing its operational speed and reliability. Moreover, the piston can now move progressively in response to the precise amount of boost pressure required for venting, rather than being limited to a binary fully open or closed state, as is the case with the factory diverter.
The outcome? Sharper throttle response, lightning-fast valve actuation, the capacity to withstand substantial boost pressure, and an operation so dependable that they back it with a lifetime warranty. You can delve into the full DV+ story below.
In contrast, other manufacturers opt for products that replace the entire diverter and solenoid, resulting in a significantly higher and, frankly, unnecessary price tag. Some simply swap out the valve within the factory solenoid without implementing the pilot actuation system. This fails to resolve the throttle response issues plaguing the factory diverter while being slower and more prone to sticking.
GFB's DV+ solution, on the other hand, offers enhanced responsiveness, affordability, and eradicates compressor surge, turbo flutter, or chirping sounds—clear indicators that the diverter isn't functioning as it should.
The DV+ Story: Unmatched Performance and Reliability!
The GM 2.0 LTG engine employs an ECU-controlled solenoid-type diverter valve, a common choice in many modern turbocharged engines. However, despite their presence since the mid-2000s, these valves still suffer from significant reliability and performance shortcomings that only the DV+ can address.
Problem 1: Leaks The factory diverter utilizes a piston with a molded plastic design that lacks effective sealing. As a result, significant leaks occur, impacting spool-up time and causing a boost drop-off at high RPMs.
The DV+ rectifies this issue, ensuring that your hard-earned boost reaches the engine by employing a bonded silicone face seal and meticulous precision in piston-to-bore clearance and surface finish.
Problem 2: Reliability In the factory diverter valve, the solenoid must move the piston through an extensive range of travel. This weakens the magnetic force the solenoid can exert to open the piston, necessitating a feeble return spring. This leaves little room to accommodate increased boost pressure or valve assembly friction without causing sticking and reliability concerns.
These problems also afflict other aftermarket products that retain the factory solenoid and continue to directly drive the piston over an extended stroke.
The DV+ ingeniously overcomes this challenge by reimagining the solenoid's role, using it to control a short-stroke pilot valve for lightning-fast reaction times and increased actuation forces. Leveraging the pilot valve, the DV+ uses boost pressure to regulate the piston's movement. This ensures that the acting forces are directly proportionate to boost pressure, allowing the piston to respond precisely to the situation. Whether boost levels are low or high, the piston adjusts accordingly. When the solenoid deactivates, the boost pressure swiftly closes the piston. This design entirely eradicates sticking due to friction and weak solenoid forces, as well as the issue of blowing open under high boost.
The DV+ is the original, patented performance diverter solution, delivering swifter responses, superior performance, and unmatched reliability, all backed by a lifetime warranty.
