Tempering Horsepower Heat: Keeping Your Cool with Heat-Handling Accessories
Engines produce lots of heat, and the more horsepower they make the more heat they generate. Only about 35 to 40 percent of the heat energy released during combustion in a gasoline engine performs useful work by creating pressure that pushes the pistons down their bores. Diesels are a little better at 40 to 45 percent efficiency thanks to a higher compression ratio and reduced pumping losses (no throttle restriction). Even so, all internal combustion engines waste more heat than they put to good use.

Manifold Matchmaker – Tips for Selecting the Right Manifold for Your Engine Build
Every engine needs some type of intake manifold to route air into the engine’s cylinders. With carbureted engines, the intake manifold has a wet plenum and runners because the manifold has to flow air and atomized fuel at the same time. Consequently, the manifold runners can’t turn or twist too sharply otherwise the heavier fuel
