Frequently Asked Questions

  • Why carbon fiber?  Carbon fiber composites are often used for visual effect rather than for functionality.  As a matter of opinion, we agree with many that the natural finish of carbon fiber can be a bonus, but we refuse to build products for appearance alone.  The fact is, fiber reinforced composites’ properties can be tailored for the individual application to optimize performance.  In the case of our induction components, the following design considerations were made:

¥       Strength:  Under extreme boost conditions or backfires, the stress on a manifold is tremendous.  Compound that with high temperatures and the material requirements are extreme.  Properly designed carbon fiber reinforcement, combined with a specially developed epoxy resin, achieves strength much higher than that of aluminum or steel.  A similar injection molded plastic manifold would require a very thick wall to achieve the strength necessary for boosted applications and would therefore be much heavier.

¥       Weight:  At less than 4.5 pounds versus 16.5 pounds for a cast aluminum manifold… what more do we need to say.

¥       Shape control:  Our unique Lost Core Resin Transfer Molding (LCRTM) process provides an economical way to produce shapes with smooth external and internal walls.  Very tight tolerances can be held as well.  Our process is similar to the one utilized by automotive manufacturers to produce injection molded plastic manifolds, but with the highest performance materials and much lower tooling costs.

¥       Heat capacity:  Heavier metal induction components absorb heat that is transferred to the intake airstream; thus robbing power.  Carbon fiber composites have unique thermal properties that can be tuned.  Specific heat is the measurement of how much thermal energy a material can hold (J / (g x C°)).  Pound for pound, carbon/epoxy composites have about the same specific heat value as aluminum.  However, being much lighter and by tailoring the properties, we are able to effectively reduce the heat capacity by approximately 87% over a stock manifold.

¥       Cost:  Yes, cost.  In addition to high material and labor costs, our induction components require a tremendous investment in tooling, capital equipment and development.  Conventional cast aluminum manifolds are much cheaper to produce, but do not perform as well in the areas mentioned above.  However, a quality custom sheet metal or CNC race manifold can easily be two to three times the cost of our manifolds (and may perform worse).
