The DV+ T9354: Performance Without the Noise

Are you looking for a boost in performance without any of the fuss? The DV+ T9354 is your go-to solution! This product is all about delivering results—quickly and quietly.

Your Essential Mod for 30% Quicker Boost

By keeping the factory ECU control and recirculating the vented air, the DV+ T9354 focuses purely on performance. Here’s what you can expect:

• Sharper throttle response
• Faster boost recovery during gear shifts
• Resolution for boost leaking issues
• Built to withstand the test of time

Dependable Technology for Optimal Performance

The T9354 is a fully recirculating, direct factory replacement for the pneumatic diaphragm type BPV (Bypass Valve) found in Ford, Volvo, Porsche, and Borg Warner Turbos. Enjoy the performance you crave without the distracting noise!

Thanks to GFB's TMS technology, the T9354 can bring your engine back to peak boost up to 30% faster than a standard diverter valve when you shift gears. Let’s talk about why this matters:

Addressing Key Shortcomings

The factory BPV has a couple of notable drawbacks in its design and function. For starters, tuned engines running high boost generate significant heat in the charge air. Since the BPV is located right on the compressor, it’s exposed to the hottest part of the intake charge, which can lead to the diaphragm rupturing. If this happens and goes unnoticed, it can damage the turbo as the ECU attempts to compensate for lost boost pressure.

Secondly, the factory BPV isn’t designed for optimal throttle response. Its soft spring and solenoid valve mean it can only operate in two states: fully open or fully shut. This lack of progressive operation can hinder throttle response, especially when you’re not completely lifting off the throttle. The T9354 addresses these issues with its robust metal and silicone construction, ensuring that the DV+ lasts a lifetime, no matter the conditions.

Performance That Shines

With a carefully selected spring rate and adjustable spring preload, the DV+ operates progressively to enhance throttle response. This is at the heart of GFB's TMS principle, which significantly reduces the time it takes to reach peak boost during gear shifts by 30%. You’ll especially notice this benefit when you’re modulating the throttle to balance your car in a corner.
