After nearly 8 months of development, testing and tuning, we have completed the latest generation of our 997 turbo EVT Performance Systems, the EVT850. The EVT850 process began with a complete engine development approach which addresses all aspects of the 997TT engine including internal strengthening. Our complete approach to developing this level of performance comes from our vast knowledge, technical experience and absolute comprehension of the 997 turbo power plant and vehicle as a whole. Our years of accumulated knowledge are the backbone of our engine development program which has been perfected with extensive engineering and hundreds of engine builds. Our methods behind creating the ultimate Performance Systems include a systematic approach which maximizes strength, reliability and optimized performance for today, tomorrow and for years to come*

*There are many companies that don’t believe in OUR method of reliable engine development. Installing bolt on components that are haphazardly constructed and are not well developed or tested is the type of shortcuts many so called “tuners” take. This inexperienced approach is what causes very costly catastrophic engine failures. When one of these engines lets go, the damage created is far more expensive than the cost to build it properly from the beginning. If someone is looking for a “HP number” and doesn’t care about how long the engine will last, then we are not the right company to build their Porsche. If someone is looking for a Performance System that has been meticulously engineered, has had systematic analysis conducted, engineering, extensive testing and tuning where all aspects have been developed in house from start to finish, EVOMS is the only choice.

Road trip for East Coast performance verification?

 

Uhhh YES! You read my mind. After the East Coast trip, I am sending her across the pond!

 

Hey Todd,this is AWHP ?If so,very strong indeed.

 

Yes, AWHP and AWTQ. That was low boost. We will test higher boost levels next week.

 

Please PM me East Coast trip itinerarys .

 

holy shnikies......can't imagine what thats like to drive...nice work!

 

My God! I still think my GT660 kit is violently fast. I can't imagine what that car feels like. I am so lucky to be living in the same city as EVOMS. I frequently make excuses to stop by, say hello and walk around.

 

Very nice Todd.

 

Cool.

One simple question. Since it won't be using the VTG's, shouldn't it be called a GT850 instead of an EVT850?
