Panchito 044™ has dyno proven, horsepower making, ports cast
right in. These port designs are race proven winners with years of use
in engines around the globe. Countless hours were spent on our
Superflow™ 600 flow bench designing the intake and exhaust ports. Our
goals were to achieve the highest port velocity and air flow through a
40mm x 35.5mm size valve. The 40mm intake port has an extremely small
port volume of 62cc and flows an incredible 161 CFM and over 300 ft. per
second port velocity, right off the shelf! The 35.5mm exhaust port has a
reduced bowl size and increased short turn radius creating phenomenal
port velocity. This higher port velocity allows for improved low end and
mid-range performance without sacrificing top end power.
CB Performance has also added extra material around the combustion chamber to give the Panchito 044™
more strength and support for larger bore cylinders. The all new high
quench combustion chamber has a volume of 57cc (54cc prior to 7/29/2019), a perfect size for small
displacement engines. The
Panchito 044™ is designed to incorporate bore sizes from 85.5mm to 94mm. With the added combustion chamber material we can machine your Panchito 044™ heads to the depths necessary for high compression applications.
As an option the Panchito 044™
can be purchased with a CNC machined combustion chamber in bore sizes
of 92mm and 94mm. The larger 61cc CNC'd chamber pushes the intake flow
numbers to an amazing 171 CFM through a 40mm intake valve!
