Q: What are "individual throttle bodies"? |
|
A: The factory induction system of the NSX uses
one single barrel type throttle body to regulate airflow into the intake
manifold and combustion chambers. Individual throttle body induction uses one
throttle body per cylinder. |

Q: What are the benefits of individual throttle
bodies? |
A: Individual throttle bodies allow the engine to
operate more efficiently by decreasing pumping losses to achieve more
horsepower. The runner length can be tuned, injectors placed at optimal
positions and angles, and air flow speed maximized. The system can be tailored
to the engine displacement, compression, cylinder head valve train design.
A properly tuned system can dramatically improve throttle response and decrease
intake tract restrictions to increase horsepower.
Manufactures typically prefer the single throttle body design as the system is
much less complicated and less costly to produce compared to an individual
throttle body system. |

Q: What are the benefits of the ScienceofSpeed
Individual Throttle Body System? |
|
A: In general,
individual throttle bodies are much more complicated than a factory induction
system. The general design including throttle linkage, placement, and flow
becomes exasperated by a V type engine such as used on the NSX. Individual
throttle body systems in general are designed for racing applications that do
not have the long use durations before the system can be serviced. Our system is
designed to provide reliable operation with extended service intervals. The
design and engineering exceeds other products through advanced CAD modeling
(such as the 3-dimensional port matched manifold) and airflow analysis. Every
component was designed to work together rather than being retrofitted from other
applications.

|
Q: Can the individual throttle bodies be used
on a stock engine? |
|
A: The ScienceofSpeed Individual Throttle Body
system has been designed to be used with modified engines. The stock induction
system is suitable to a stock engine. However, as the engine becomes modified,
the stock induction tract will become restrictive and lose efficiency. |

|
|
Q: What type of engine management is required? |
|
A: At this
time, The ScienceofSpeed Individual Throttle Body system requires the use of a
cable throttle linkage and stand alone engine management. We offer the AEM
Engine Management System with a supplied base calibration for our engine
packages. |
|
|
|
Q: Can the individual throttle body system be
used with forced induction? |
|
A: In theory
the system could be used with forced induction. However, due to the pressure and
heat generated, the system would need to be significantly modified. We have not
tested this configuration, and do not offer support for it's use.
|
|
|
|
Q: What does the system use for air filtration? |
|
A: The system
uses a carbon fiber air box that supports hatch induction or side vent
induction. A large filter element is enclosed in the air box that provides
excellent air filtration and flow. |
