2007 997TT With EVT775 Kit, Champion RS171 Wheels & SharkWerks Suspension

This 2007 White 997 TT came to us straight from the Porsche dealership and originally for the venerable Stage IV kit. We set about changing the exhaust, cats and headers to allow the car to breathe better and let the turbos spool up faster and also sound more aggressive. On the second round in order to step up to the EVT700 we added the EVO intercooler kit, EVT700 turbos and clutch kit. Custom 19 inch HRE 893R wheels were also added.


The first phase is to get the car on our super-low profile lift, remove the front bumper and let the car cool down.


On goes the MillTek Exhaust system matched with a pair of TechArt dual tips


Next we tackle those restrictive looking factory headers (carried over from the 996TT). Notice the unequal length tubes, which are also rough on the inside causing turbulence instead of free-flowing exhaust gases that your turbos require for a quick spool.


Next we remove the stock turbos and replace them with the EVT700 turbos and the EVO
BRV's.


Out comes the transmission and stock clutch in order for our beefier Stage II clutch. Higher clamping force is needed for this level of power.


Our beefier stage II clutch kit is used to hold the power and keep it
streetable


After the intercoolers are removed and housings taken apart, with some minor
modification, we are able to install the EVO intercooler kit.


One of the final touches is the less turbulent Plenum from IPD.


19 inch light weight HRE 893R wheels were choosen.


There she is all ready for home...

A few more changes were made to this car since its original trip to SharkWerks, including:
EVOMS Turbo Ducts
EVOMS Crank Pulley and Belt
EVOMS Ignition Coils and Plugs
EVOMS Headers
Fabspeed 70mm Exhaust
EVOMSit Software "Switcher" for multiple octane maps

The car was tested and tuned at Evolution Motorsports in Arizona, including a live dyno tune with EVOMSit proprietary ECU emulation software to ensure maximum performance and reliability.

Here are the results using 91 and 94 octane:


A few of the suspension parts on tap waiting to go in:


The customer wanted to maintain a factory-level compliant-like ride so we choose to use the TechArt lowering spring kit (lowers the car by 20mm).

In go the front springs:



In go the rear springs:


Also in the rear you can see we've installed our upgraded upper control arm adjustable rear links:


These kits allow the negative camber in the rear to be correctly adjusted to factory specifications, improving handling and road feedback. On lowered cars, the OEM links do not allow for sufficient adjustment, which forces an improper alignment and leads to excessive tire wear. The Adjustable Rear Link (AKA, "Dog Bone") Kit was designed to eliminate this problem. Additionally, the neoprene bushings have been replaced with steel monoballs, resulting in more direct handling feel and less movement among suspension components.

Also you can see the lower control arm was replaced with an upgraded adjustable toe-steer / bumpsteer kit:

On lowered Porsches with a factory toe steer link, the limited adjustment results in incorrect toe geometry. This part replaces the OEM part with a fully adjustable unit, allowing the toe to be adjusted to factory specifications.

The inner, neoprene bushing is also replaced with a steel monoball, which reduces dynamic changes in rear toe and further tightens up the car's handling.

What you can't see is that we also installed a solid monoball control arm kit. Our Monoball Lower Control Arm Kit replaces the neoprene factory lower control arm inner-pivot bushings with steel monoball joints, giving more direct handling and better road feedback. This increases the precision of the pivot motion of the control arm as it travels up and down under cornering.

Buttoned up with a set of the RSS adjustable front/rear sway bars the car is VERY driveable and doesn't bob/weave either. It certainly sticks.... I really like this set up and drove it daily on our 2009 997S project car as well.

Finished:




The car was also given a set of Champion RS171 light weight wheels in black and there she is ready to go home:)
