997 GT2 ECU Tuning &
EVT670 GT2 Performance System
|
Evolution MotorSports launches
its EVOMSit
Performance Engine Software and EVT670
Performance System for the new 997 GT2. The EVOMSit
intelligent ECU Tuning, combined with EVOMS VTG Headers,
HJS 200 Cell
Catalyst Pipes, Clubsport intercoolers and EVOMS BRV's completes our potent performance system
that produces a safe and effective performance gain from the 997 GT2 with
bolt on components. Our EVT670
system
replaces the restrictive ceramic catalysts with a more efficient 200
cell HJS metal substrate catalysts. Additionally, the restrictive
OEM headers are replaced with our
hand built VTG headers with pyramid merge collectors. The EVOMS headers
have been engineered with the proper length and diameter primary tubes
to match the flow and output of the modified GT2 engine. They are
then ceramic coated to help keep
the heat inside the tubes which helps with exhaust velocity and
improved overall efficiency.

EVOMS Dyno
Facility / Methods: |
The EVOMS 997 GT2 is pictured in our
state of the art AWD dyno cell. Note the proper ventilation and
custom fan system that replicates wind speeds of up to 100 MPH.
Our cooling and airflow system has been perfected over the past
two years specifically for the Porsche 911 models. Our methods are
extreme, however this helps enable us to conduct the MOST accurate
testing and best performing tuning systems in the Porsche
community - BAR NONE! Our dyno methods demonstrated here is
what helps define our core belief:
Intelligent Tuning.......
......INSANELY tuned |

All of the EVOMSit
Performance Engine Software has undergone rigorous testing under
extreme conditions. We have evaluated and tested with various octane fuels
in the heat of the dry Arizona desert, the cool temperatures and humid
weather of the California coast, the high elevation of the Colorado
Mountains, the heat and ocean humidity of Mexico and the frigid elements of
Minnesota.

Once again we have demonstrated that our intelligent tuning stands ahead of the rest. Not
only are the power gains and overall performance phenomenal, we were
able to improve the power while solving
a problem that Porsche chose not address - making safe and
reliable power on 91 octane fuel! Our upgrade is 100% 91 octane friendly
and utilizes our
IST (Integrated Switching Technology) which allows
automatic switching for 91, 93 or 100 octane fuel. |
