Description

CB Performance is setting standards with VW cylinder head innovation. Our latest in-house design incorporates the cooling efficiency of an original VW head casting while still offering amazing performance results!

CB Performance has been working directly on the Panchito 044™ with the engineers of AutoLinea, an OEM supplier to many of the world’s top automotive companies. AutoLinea is a tier 1 supplier with a ISO9001:200e quality control standard. This ensures that each Panchito 044™ has passed very stringent metallurgy and machining inspections throughout the production process.

The all-new 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 162 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!

The Panchito 044™ comes complete and ready to run. So give us a call today, and bolt on a set of built-to-last street performance cylinder heads.

Designed to fit 1600 based engines for the T-1, T-2, and T-3 VW. Sold Individually.
