Agency Power has developed these OEM Boost Recirculation Valves (BRVs) for the Porsche 997 Turbo VTG turbochargers. Like on the older 996TT, the stock valves use a rubber diaphram which will leak boost on the higher RPM. This part also deteriorates over time leading to boost failure. The new Agency Power BRV uses a piston and spring design like our other popular diverter and blow off valves we have been producing since 2005. This design holds boost pressure all the way to redline and with the VTG design, helps boost come in stronger. The 997 VTG Turbos have the valve mounted directly on to the turbocharger. To add this enhancement on the 997 Turbo, Agency Power had to engineer a product that would be a functional OEM replacement.

Each valve has been CNC machined from 6061 aluminum. The base of the valve was precision engineered down to the ten-thousandth to fit into the stock VTG turbocharger. Inside the base is an aluminum piston that has been 3D machined. This piston is hard anodized and inconjunction with the provided grease and o-rings, provides an air tight seal as the piston moves up and down. Agency Power then had to get the proper spring rate to handle stock boost or high horsepower cars. The top of the valve mates to the base and then 3 allen head bolts fasten it to the turbochargers. The top features a boost nipple for easy connectivity of the stock vacuum line like the OEM unit. The top features a laser engraved AP logo and Agency Power text while the entire assembly is anodized in either brillant blue or stealth black. As tested in a VR750 package car, these valves held boost consistantly. The valves are sold in pairs and fit all Porsche 997 Turbo and GT2 vehicles. These are Made in the USA.

very interested, please PM price quote plus shipping (residence PA). can my porsche dealer service tech install this new design? what is the difference between AP BRVs compared to EVOM BRVs?; i was about to get EVOM BRVs installed. any increase in hp, or just boost response? difference with "butt" dyno? TIA

 

I will PM you now. The install is SO BASIC as it is 3 bolts remove and insert new ones. Probably take 30 mins. The difference? Well there are some changes I am sure, but I am not familiar with their product. With boost response quicker, you should see initial torque come on higher too. As well as improved horsepower at top end holding boost. PM coming with a special price so you can give us your feedback.

 

Any "blow off valve like sounds" with this products Merl?

Thanks for the order KA! Look forward to your review and pics.

 

Here is a couple of pictures to show how they look installed in the turbos -

It’s so true, the sound is unique; it almost feels like you have a jet engine.
