The New Werks B7KE "Kortz Edition" .21 Racing Engine
Hi guys, I thought that I would take a second and start an official thread to discuss our new B7 Kortz Edition engine that we are getting ready to launch! This has been something that we have been testing and developing over the last 2 years and I believe is arguably the best engine that we have ever made!
Here is the official press release on it:
Introducing the .21 B7 Kortz Edition, Werks Racing’s newest addition to it’s “Team Line” of engines. A special engine to celebrate the 10+ years that RC Pro Jeremy Kortz has been competing with Werks Engines! Designed from the ground up to represent the ultimate .21 off-road racing engine incorporating all of the best features and machining possible!
The B7 Kortz Edition starts off with our proven case design that features additional stiffening ribs around the sleeve area to help better control expansion due to heat. We have significantly modified the top of the case to reduce mass and developed a new recessed cooling head design that completely envelopes the top section of the engine case. This new design not only greatly reduces the overall height and CG of the engine but also significantly improves cooling!
A new long stroke 7 port design offers tremendous torque with exceptional top end with what is to date the smoothest, most linear power band of any engine that we have ever made! This super linear power band allows easy modulation of throttle inputs, ideal for racing!
The B7 Kortz Edition also features a new lightened, epoxy filled and tungsten balanced crankshaft. These features reduce mass for quicker acceleration, improve fuel flow and reduced harmonics. A CNC from billet piston with knife edged connecting rod, ceramic rear bearing, new high quality double shielded “Swiss” front bearing, new o-ring sealed turbo head button and revised carburetor for better stability and idle performance have also been incorporated in the B7-Kortz Edition.
Designed from the ground up with Jeremy Kortz using input from his 10+ years racing with Werks Engines, this is the pinnacle of high end competition oriented engine design. The B7KE is a fuel efficient motor that provides tons of torque and overall HP with a super smooth and drivable power band allowing you to put down the power exiting corners without excessive wheel spin and able to compete at the highest levels. The new B7 Kortz Edition, an engine worthy of carrying the Kortz name, a driver that proudly represented Werks Racing in 3x 1/8 Off Road Worlds finals, multiple national buggy and truggy finals and win after win during the last decade!
