Dr. John C. Morrison is one of the foremost authorities on the analysis of the induction and exhaust processes of high-speed engines. Together with Philip Smith, he gives a thorough explanation of the physics that govern the behavior of gases as they pass through an engine, and the theories and practical research methods used in designing more efficient induction manifolds and exhaust systems, for both competition and street use.
Chapter topics range from Simple Flow Problems and Sound and its Energy to Designing a System for Racing. This authoritative book will lead you through the complex theory to an understanding of how to design high-performance exhaust and intake systems for your own particular application.

The main purposes of a Heating, Ventilation and Air-Conditioning (HVAC) system are to help maintain good indoor air quality (IAQ) through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in schools. The choice and design of the HVAC system can also affect many other high performance goals, including water consumption (water cooled air conditioning equipment) and acoustics.
Yet wind, stack effect, unbalanced supply and return fans and constantly changing variable air volume (VAV) systems can cause significant under- or over-ventilation, which can affect IAQ and energy costs. Combinations of these effects can even cause the intake system to actually exhaust air.
Ensure that all system components, including air handling units, controls and exhaust fans are easily accessible. To help ensure that proper operation and maintenance of HVAC system components will be performed, it is critical that the designer makes the components easily accessible. AHUs, controls and exhaust fans should not require a ladder, the removal of ceiling tiles, or crawling to gain access. Rooftop equipment should be accessible by way of stairs and a full-sized door, not a fixed ladder and a hatch.
Many misconceptions exist surrounding how exhaust systems are tuned and what terms like backpressure and scavenging really mean for performance. Hopefully with this reference you will be better equipped to devise what your specific exhaust system needs are and how to reach that destination.
Runners are designed to promote unrestricted flow, while encouraging high velocities. This is the reason porting must be done with care so as not to disrupt the engineered fluid dynamics of the head. When the exhaust valve opens the expanding hot gasses rush out of the exhaust port backed by the upstroke of the piston. In OEM applications this generally means a bank of cylinders dump collectively into an exhaust manifold.
Exhaust manifolds are generally the first line of disappointment when it comes to exhaust routing. Because the cast construction has been designed for ease of production, they are generally heavy, and do not offer desirable mingling of the exhaust pulses. Though some manufacturers have improved on the unequal length manifold, they are often discarded in favor of aftermarket solutions.
Tuning an exhaust system to a given application is a case-by-case basis challenge. The displacement, exhaust valve size, induction system, cam profile, exhaust port design and RPM range all factor into deciding what form the exhaust system should take. General rules of thumb are easy to grasp, but applying them correctly is where things get tricky.
To generate the most aggressive scavenging effect is a delicate balance, one heavily driven by camshaft lobe separation (generally narrower equals more because increased valve overlap leaves the exhaust valve slightly open, drawing this vacuum while simultaneously the intake valve is open), and exhaust sizing.
Mufflers are a necessary evil in the eyes of most speed freaks, but they need not be a hinderance to performance. OEM style mufflers generally reduce noise by forcing the exhaust gases to navigate a maze of chambers, perforated tubing, and tight bends relying mostly on the slowing of exhaust gases to achieve their goal.
