The Vivid Racing 630 Horsepower kit for the Porsche 997TT was developed from our very own Project Car. Partnering with Porsche aftermarket tuning leaders such as Agency Power and Softronic, we have put together a package that will take your vehicle to the next level of power and performance using your stock turbochargers. At our Arizona facility, we have dyno tested each one of these parts individually and as a package to showcase their performance capabilities. Our vehicle and products have been put through rigorous driving tests to ensure their strength and reliability. In 5 days, we ran the car 2500 miles in the 2008 US Leg of the Gumball 3000 Rally. This included high speed runs, mountain roads, and race tracks. The consistency, reliability, and pure excitement of this package are one to consider.
Every turbocharged vehicle needs to breathe well and have less restriction after the turbos to produce strong horsepower. Our VR630 Horsepower kit starts off by improving the exhaust flow and efficiency with the Agency Power Exhaust System. The exhaust has 200cell high flow catalytic converters and a muffler design to sound aggressive through the revs but not drone in the cabin. The exhaust design was developed to provide maximum power with a clean race tone. Besides saving almost 30lbs off the rear end, its OEM fitment and style uses the stock tips or other aftermarket ones. In addition to our Agency Power exhaust, we add high flow headers to improve turbo spool and low end torque. The Agency Power headers are a direct replacement for the stock units. They feature a better collector and equal length runners for the best exhaust flow possible. The headers are all stainless steel and feature high quality robotic TIG welding. The exhaust components will reduce restriction which causes your boost to not build up fast and drop off tremendously with the stock exhaust system. You will notice faster throttle response and stronger pull throughout the entire RPM range.
Along with the exhaust components, we include the upgraded Agency Power Boost Recirculation Valves to help boost come on sooner and hold pressure more consistant. These OEM replacements feature a piston and spring design over the diaphram unit. To help with the increase in power, we also change out the spark plugs with Denso IK22 Iridium plugs. The biggest change in the Porsche 997 Turbo performance is with the ECU upgrade. Vivid Racing has developed an incredible tune using Softronic ECU Tuning. They use the latest technology to bring out the aggressiveness in your 997TT while keeping your vehicle safe and reliable. Softronic is the only company that can flash your ECU through the OBDII port. Each timing and lambda table are tuned to give you the best overall package no matter the RPM or throttle position. Softronic retains the Sport feature and if you do not have Sport, Softronic can activate it for you. Flashing can be done for 91 or 93 octane. There is no need for a race gas map as the ECU will adjust accordingly. You can also flash the ECU back to stock with your true original file at anytime. For questions in regards to this process, you can contact one of our Porsche Specialists.
The finally upgrades on the VR630 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.
We have tested our horsepower numbers on our Mustang All Wheel Drive dyno. You can read more about our dyno and how it works here. The Mustang Dyno reads much lower then some of the other dynamometers out there. As tested in AWD and on 93 octane, our Porsche 997TT made 511awhp and 508ft/lbs of torque. With a 25% drivetrain loss, this equates to 638 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.
