Porsche 911 3.5-litre twin plug MFI engine running Classic Retrofit CDI+ ignition! 380hp/330 ft lbs

Porsche 911 3.5-litre twin-spark engine running a pair of Classic Retrofit CDI+ ignition upgrade units (seen to left of stand). Appearance of our famous CDI+ spark box is identical to the original Bosch units - it can even be built into an original case - but the CDI+ offers mappable dual spark. It is suitable for road and race cars - we manufacture models to suit all applications.

The units are dyno proven to increase power, torque and driveability. Fuel economy is increased as you need fewer revs for the same output! Idle is much smoother on both road and race cars.
Classic Retrofit has designed 3-pin, 6-pin and 8-pin CDI upgrades for everything up to and including Porsche 917! We also ship worldwide. See our webshop at www.ClassicRetrofit.com and get in touch with any questions.
Engine build by Jaz Porsche. Setup on the dyno at BS Motorsport. See our other videos for more dyno action!

This is an awesome motor! I am considering a 3.5 build muself! I was wondering what C/R Piston you're using? A 20/21 Cam? What is your design for your twin plug setup?
Thanks

Hi and thanks for the comment. It's not our engine unfortunately so cannot help with technical questions. JAZ Porsche built this engine. Good luck with your build!
