The Vivid Racing Stage 3 Horsepower kit for the Porsche 997 Turbo gives you everything you need to get the job done without touching the turbos. Giving you faster turbo spool, huge torque increase, aggressive pull through the top end, better sound, better throttle response, cooler running temperatures. _x000B__x000B_Every turbocharged vehicle needs to breathe well and have less restriction after the turbos to produce strong horsepower. Our Stage 3 Horsepower kit includes all the parts from Stage 2 with the addition of our 800HP intercoolers, larger CTT 78mm throttlebody and plenum, and our full cold air intake kit. We also include a set of our high flow racing headers to further the exhaust performance. _x000B_ _x000B_The finally upgrades on the VR650 package include the addition of improved cooling using the Agency Power high flow intercoolers and silicone boost hoses. These intercoolers support up to 750 horsepower and have 40% more cooling capacity then the stock ones. The silicone boost hoses are replaced with OEM style CNC machined fittings to keep pressure consistant and reduce the chance of blowing a hose off. We also include our Agency Power Carbon Fiber Cold Air Intake Kit. This cold air intake kit features dual K&N high flow air filters that are contained in a custom carbon fiber housing to work with your stock air inlets. This intake greatly improves throttle response and mid range RPM pull. _x000B__x000B_As tested here at Vivid Racing, the Stage 3 kit performed quite well. The Mustang Dyno we use reads much lower then some of the other dynamometers out there. As tested in AWD and on 91 octane, our Porsche 997TT made 511awhp and 508ft/lbs of torque. With a 25% drivetrain loss, this equates to 648 horsepower to the crank. Our vehicles baseline was at 331awhp and 317ft/lbs of torque. Both tests were done in the Arizona summer months with an outside temperature of 100F degrees. _x000B_ _x000B_ _x000B_Vivid Racing Stage 3 Porsche 997 Turbo Kit Includes - _x000B_ _x000B_Agency Power Titanium Exhaust System _x000B_Agency Power High Flow Headers _x000B_Agency Power Boost Recirculation Valves _x000B_Agency Power High Flow Intercoolers _x000B_Agency Power Silicone Boost Hoses _x000B_Agency Power Carbon Fiber Intake _x000B_Agency Power TB/Plenum Kit _x000B_NGK 1 Step Colder Spark Plugs _x000B_VR Tuned ECU Flash Kit _x000B_
