Evolution Powersports Maverick X3 Plenum Reinforcement Brace
The Clamp is here!!!
It was developed as a collaborative project between Evolution Powersports and CA Technologies to prevent the OEM intake plenum from blowing apart and ending your trip. There have been many cases of OEM plenums failing on stock engines and modified engines producing even modest boost pressures. We have had countless failures on our in-house X3’s over the years and knew there had to be a way to solve this. EVP is excited to share a solution to this common issue. The Clamp is a lightweight but durable brace that “clamps” around the OEM intake plenum, preventing the premature failure of the plenum by reinforcing its weak points.
The Clamp was developed using the latest technologies, including 3D scanning to give it a perfect fit. Constructed of 6061-T6 aluminum, this CNC machined brace was designed to have optimal strength while being mindful to overall weight. It has been extensively tested on race vehicles and highly modified engines to ensure its effectiveness and durability.
Simulated Test: We have conducted an extensive simulated testing regimen on The Clamp. The validation consisted of repeatedly applying pressure to OEM plenums – one with and one without The Clamp. As you can see in the video here, the plenum with The Clamp withstood ~70 PSI of pressure with no stress or damage. We then tested identical plenum without The Clamp installed. When tested in the same manner, it blew apart at ~35 PSI of pressure.
In this test we were able to simulate boost pressure, but real world factors such as heat, vibration, shock and engine pulsation could not be accounted for. This is why non clamped OEM plenums fail at much lower boost pressures. While 35 PSI may be an unrealistic amount of boost for you to push in your vehicle, keep in mind those other variables that play a part in real-world applications. Experience has shown countess plenums failing at boost pressures as low as 22 psi and some at stock (15 psi) of boost pressure.
