Evolution MotorSports - High Energy Discharge Ignition Coils
 996/997 Twin Turbo, GT2 and GT3 Applications

Design Inspiration:

Evolution MotorSports High Energy Discharge (HED) ignition coils were developed out of necessity and proven affective on our 1200 HP 996TT engines to provide increased spark energy and improve overall engine performance.  Our development process began more than 2 years ago when we had reached the limits with the output of the stock coils.  Since we continuously push the flat-6 engines to the extreme, we developed an ignition coil that improved performance and could withstand the punishment that we inflicted on them.  Although we developed the EVOMS HED ignition coils for the Motorsport environment where extreme heat, vibration and high RPM's are common place, our ignition coils also make a significant performance improvement to any power level Porsche. 
 

Fits all 996TT, 997TT, GT2, GT3 Applications from 2001-2010

Test Vehicle: 2003 996TT

 

Modifications:
EVOMSit ECU Calibration, Hitachi MAF w/ EVOMS V-Flow Air Intake, Sport Exhaust - No Catalysts, 91 octane fuel


The increase in power shown in the above dyno graph is due to the installation of the EVOMS HED ignition Coils only.
Better, more complete combustion and cleaner burning spark attribute to the increased power and torque

 

Conclusion:

When Evolution MotorSports pushes the Porsche engine well beyond its engineering limits, we are usually the first to not only find these limits, but we find and develop a solution to them.  The development of these coil packs was no different.  Our process began with figuring out the limitations of the stock coil and determining a proper way to solve the problem.  Like all of our product development endeavors, designing the best solution is top priority no matter the expense involved.  No other company devotes the time to properly design, engineer and test performance components like we do.  The products we design in our various performance systems are properly matched for the rest of the components which yields peak performance today, tomorrow and for years to come.
