Description
 
Just as the 2010 Porsche GT3s start to reach local dealerships with a new 3.8L engine direct from Porsche, Evolution MotorSports, in conjunction with Performance Partner SharkWerks, has upped the ante once again. Back in 2007, we built a similar 3.8L engine for the GT3, and after 19 months of testing, tuning, hundreds of dyno runs, countless track miles, and several state highways worth of road testing, we have upped the stakes once again. We continued the development process on Sharkwerks’ Viper Green GT3 RS to engineer an even bigger displacement engine upgrade package. Further improvements have been made with our proprietary intake and exhaust camshafts. Read on to discover how we can transform your 3.6L 997 GT3/RS into a 500+ HP MONSTER that will sing all the way to 8800 RPMS. Click here to access the: 3.9L Press Release

Listed below is a quote from the editor of Excellence Magazine when he reviewed our 3.9L conversion in Sharkwerks Viper Green 997 GT3RS:

What’s on my mind ...weeks after the RS leaves...is the winner of this match up, and it’s not a car. It’s an engine, and I’m a handling guy. As that sinks in, I realize something else.

Much as I love short-stroke 2.5s and 2.8s, today’s GT3 engines eclipse them. But this 3.9 vanquishes every GT3 flat six I’ve tried. Including the ones in the 997 GT3 Cup and RSR? In a word, yes —in part because they’re overshadowed by a sequential transmission that makes F1 noises and in part because they’re not built to be enjoyable — they’re built to be raced. The 3.9 feels RSR strong but more refined than the production 2010 GT3’s 3.8. Put simply, it’s the best normally-aspirated flat six I’ve tried.

That ranks it up there with my top two Porsche engines of all time: the 469+hp, twin-turbo flat six in 1988’s Ruf CTR and the 605-hp, 5.7-liter V10 in 2004’s Carrera GT. It’s hard to see how a flat six can get any better, but perhaps Porsche under Ferdi­nand Piëch will show us.
