Product Information

With the success of our VR825 kit achieving a 206.2mph at the Texas Mile event in March 2010, we thought we had squeezed the most we could out of the 997 Turbo... But we were wrong.  This is where we introduce our VR900.  Built and based off all the principles and products of our other kit, the VR900 goes 1 step further with larger injectors and a special custom tune from us.  Having proved its power capabilities in cars all over the world, we reflash the ECU via the OBDII port to make the 997 Turbo a true monster.  With increased fueling from 80lb injectors over the stock 57lb ones, we are able to run the 997 Turbo to a new level.  Our test vehicle was a 2009 997 Turbo Tiptronic and on 93octane at 1.5bar of boost, we were still slipping all 4 wheels on our Mustang Dyno while putting down 788awhp.  The Mustang Dyno generally has a 20-25% drivetrain loss from crank horsepower.  Do the math and that is over 900bhp.  What makes the VR900 kit just as unique as our VR825 kit is its usuability and driveability in normal conditions.  The cars are smooth, idle normal, and at partial throttle, cruise through the streets like any other un modded 911.  However when you take that throttle to 100%, your 911 Turbo becomes an animal with 1 goal in mind and that is to rip the heads off whatever is in its way!

The core of the VR900 kit is based around Garrett GT3076 .63a/r turbochargers. With a 4inch compressor inlet, these ball bearing turbos spool up making peak torque at around 5000rpm. Making 400ft/lbs of torque at 3800rpm and almost 550ft/lbs to the wheels at 4500rpm, there is power to be used in any driving situation. In conjunction with the Garrett turbos, we utilize Tial 44mm or Turbosmart Gate40 .8bar external wastegates which bypass the stock exhaust system to create brain punishing torque at full boost. The use of these turbos and wastegates requires special headers as the fitment is different then stock. Our headers are hand built in-house using 16 gauge, 304 stainless steel that is TIG welded. Our thick water jetted flanges and custom made merge collector provides you the best performance. The headers bolt to the heads the same, except use a 4 bolt flange to mount the Garrett turbos and require an extension just off the collector for the external wastegate. The turbos cannot make the power on their own and require additional products that we have manufacturer specifically for the VR900 kit. In addition to the headers to mount the turbos, you must also change the oil and water lines. Porsche uses proprietary fittings for their oil and water lines to the VTG turbos. We supply new AN fittings, steel braided oil lines, coated water lines, and banjo bolt fittings to mount to the Garrett turbos. So customers can retain their stock mounted aftermarket exhausts with the Garrett turbos, we include steel black oxide coated exhaust adapters which mount to the turbos to bolt the exhaust too. This enables you to retain your favorite aftermarket exhaust sound and style with out having to get a custom one made.

Turbocharged vehicles need to receive air, and cool air for that matter. Because the stock air box or aftermarket intakes still do not provide the flow and cooler air temps we require, we have relocated the intakes to the fender ducts over the intercoolers. The custom made Agency Power aluminum intake pipes feature appropriate diameter and bends to give you the clearance and retain OEM trim pieces. Once installed, the filter sits on top of the intercoolers inside the modified plastic housing to receive direct and cool air away from the engine bay. The intake pipes include a 1-inch return port for the blow off valve to recirculate. Each intake pipe is connected to the turbo with a 90 degree reinforced silicone coupler. The OEM MAF tube which is removed from the stock intake fits between a high flow K&N cone filter and provided silicone coupler to complete the system. Continuing with our cooling system, we modify the Agency Power high flow bar and plate intercoolers and include the lower 5ply silicone boost hoses that connect to the turbochargers. These intercoolers are 40% more efficient then the stock units. The modified intercoolers feature 76mm aluminum outlets going into the Y-Pipe. This allows us to maintain a full 76mm diameter all the way to the throttle body. The aluminum Y-Pipe features smoother transitions and an internal air guide to efficiently bring air into the engine. Since the stock VTG internal boost recirculation valves are deleted, we include dual Agency Power adjustable blow off valves off of the Y-Pipe. These valves are designed to vent 50/50. This means that 50% of the air is recirculating back into the intake pipe 50% is going to atmosphere. This keeps the MAF sensor happy eliminating any stalling or idle issues 100% vent BOV;s cause while helping the turbos stay spooled between shifts by venting out 50% of the air. The Y-Pipe features a CNC machined mount for the stock MAP sensor and a side mount for the Greddy Profec B boost controller required to use with the Garrett turbos. The kit also includes a special laser jet aluminum plate to separate your moving pulleys and belts from anything that may fall in the way. Not only is this for safety, it also cleans up the engine bay. Next to achieve more air into the intake manifolds, we use the Agency Power race plenum kit. The plenum kit includes the 78mm Cayenne Turbo throttle body mounted to our matching larger aluminum T plenum. All of these pipes are then finished in your choice of powdercoat for an OEM or show look.

Because this kit is using external wastegates, it is not possible to control the boost with the factory solenoid. We include the Greddy Profec B boost controller which enables you to have different boost settings for pump and race fuel. The Greddy has a high and low boost setting as well as a digital boost read out, memory for peak boost, and even a warning feature in case of over boosting. What brings all of this performance together is the custom ECU tuning. ECU flashing is done through the OBDII port of the vehicle. The ECU flash for the VR900 kit is designed to eliminate any warning lights from the removal of the VTG turbos. The flash will also raise your rev limiter by 500rpm's and will retain the sport mode feature for better throttle response. For those running catless, we can raise the O2 sensor limiters to avoid any check engine lights.  With the appropriate MS109 octane fuel, the car can safely run 1.6bar of boost and on pump fuel, 1.3 bar.

To further the fueling needs of this more aggressive kit, we have added 80lb injectors in replacement of the OEM ones. These injectors flow quite a bit more then stock to give the engine the fueling it requires. With the ECU dialed in to control the fuel based on your throttle percentage, rpm, and load, this combination allows for more advanced timing to be run and ran safely.

The VR900 is a complete kit requiring modification to OEM parts. The kit includes everything you need except for the transmission upgrade parts for either a 6spd or a Tiptronic and a exhaust system. This will be hands down the fastest thing you will have ever driven!
