[. . . ] Unfortunately, the high cost of these systems--and current emissions regulations--prevents their wider acceptance. The simulation model for the Individual Runner choice in the Manifold Type menu assumes that the runner sizes and the carburetor venturi diameters are of "medium" dimensions. Runner length, that is, the distance from the valve head to the top of the carburetors, is also assumed to be "mid-length, " and so the simulation uses a mid-range rpm power bias. applications, since this induction system is commonly used on street engines or in road-racing applications that require good throttle response and a wide power band. menu selection can also model fuel-injection systems with small-diameter, medium-to-long length individual stacks. For large-diameter, short-length injectors, like drag-racing systems, the tunnel-ram manifold selection provides a better induction model (see the previous tunnel-ram description). Tuned-Port Injection Manifold The TPI manifold was introduced by automakers in the mid 1980's and millions of them remain on the road today. It represents the first mass-produced induction system that clearly incorporated modern wave-dynamic principals. Dyno2000 Advanced Engine Simulation--53 Sequential-Fire Injection Modeling Tuned-Port Injection--This manifold was introduced by automakers in the mid 1980's and millions of them remain on the road today. It represents the first massproduced induction system that clearly incorporates modern wave-dynamic principals. To optimize low-speed torque and fuel efficiency, the TPI manifold has very long runners (many configurations measure up to 24-inches from valve head to airbox). The runners on most TPI systems are also quite small in diameter--again, to optimize low-speed power--and, unfortunately, create considerable restriction at higher engine speeds. Characteristic power curves from this type of manifold are slightly to significantly above a dual-plane up to about 5000rpm, then runner restriction and an out-of-tune condition substantially lowers peak power. The TPI is a single-plane design that functions like a long-runner tunnel ram. Each runner is completely isolated until it reaches the central plenum. This design tends to maximize pressure-wave tuning and minimize wave interactions. Since fuel is injected near the valve, the TPI system delivers precise air/fuel ratios with no fuel distribution or puddling problems. There is a wide range of aftermarket parts available for the TPI, including enlarged and/or Siamesed runners, improved manifold bases, high-flow throttle bodies, and sensor/electronic modifications. The Tuned-Port Injection selection in the Manifold Type menu models a stock TPI. However, increasing the airflow (from the Induction Airflow menu) makes it possible to model some of the benefits of larger runners and high-flow throttle bodies. There are now many "TPI-like" EFI (electronic fuel injection) systems available for small- and big-block engines. Some of these custom packages are based on a shortrunner tunnel ram model. Do not use the TPI manifold model to simulate these manifolds, instead, select a single-plane (for small-runner systems) or the sequenMany TPI and EFI (electronic fuel injection) packages are based on shortrunner, high-flow tunnel ram bases and use sequential-fire electronic injectors. Some longer-runner systems, like this manifold from Induction Technology, allow much greater airflow than the original factory TPI and still provide substantial low-speed torque. [. . . ] Smallblock--A generic term that usually refers to a V8 engine with a displacement small enough to be contained within a "small" size engine block. Stroke--The maximum distance the piston travels from the top of the cylinder (at TDC) to the bottom of the cylinder (at BDC), measured in inches or millimeters. The stroke is determined by the design of the crankshaft (the length of the stroke arm). Top Dead Center or TDC--The position of the piston in the cylinder bore at its uppermost point in the stroke.
