Hello all! Progress has been slow but here are some pics of the engine and new intake manifold. As many of you have guessed this project will have very radical running gear for a Cobra. The engine is a Mazda 20B 3 rotor Rotary. The engine weighs just under 200 pounds and should produce around 400 HP. With triple DCOE Webers this build is very radical even for 20B fans. HP to weight ratio should be about 500 hp per ton. For those of you that follow the Rolex and Continental Tire series this is the same engine that all of the RX-8's have run in previous years. Except I won't be limited to 8600 rpm's to make it fair for the other competitors. This engine transmission combination should really balance the car for handling as well as acceleration. I have always believed in Colin Chapmans ideas of "Simplify and then add lightness". I also have a Lotus 7 powered by a 13B 2 rotor. 225 HP and 1300 pounds.
