- For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 1.98 in (50.5mm) valve; we believe this is the largest valve available with the highest flow capacity.

- The V-Band design aluminum mounting clamp gives a very clean and unique appearance. The clamp is anodized and uses Stainless Steel hardware for a long lasting, corrosion-free appearance.

- The valve seal utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance.

- The Blow Off Valve also comes with our own machined aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb for quick actuator response. The actuator has a high temp silicone Nomex-reinforced diaphragm for long life.

- An aluminum or mild steel weld base mounting flange is furnished with each unit. Stainless Steel is available at an additional cost. The use of 6061 aluminum allows the housing to be anodized with a selection of colors where most cast aluminum alloys can not be anodized. This allows the individual to match, or coordinate, the engine compartment color scheme. The clamp, valve, and housing will be offered in Silver, Black, Red, Blue, and Purple to allow you to mix or match the clamp, body, and valve assembly to create a look unique to your application. You may also purchase a plain or unassembled unit to anodize or color-coat as you like.

The Super AVC-R is the premium closed-loop electronic boost controller on the market. The AVC-R allows flexible control over virtually every aspect of boost control and adds new innovative functions such as injector pulse monitoring and gear specific boost control.

Some key functions include: RPM-based boost and solenoid duty cycle control, scramble boost, self learning mode, 2D ghost map trace mode, analog display mode, real time replay and peak hold data modes. The AVC-R utilizes an ultra-fast microprocessor and a high quality solenoid valve to control boost. The result is ultra-fast response and accurate, stable boost control.

Nelson Performance offers a unique tuning solution. For our customers that are running 5 psi of boost, Nelson has a base tune for each of the vehicles. To ensure no downtime, Nelson sends a PCM with the tune out it and you return your old PCM to Nelson after the new tune is installed and working on your vehicle.

If you're not happy with the tune or if you would like to run more boost, Nelson Performance guarantees their tunes and will change it for free as long as you own the car. All you have to pay is shipping on the PCM.
