The exhaust turbine side can be likened to the pulley of a blower, although it is
not truly dependent on engine rpm to dictate turbo rpm. Many factors come into
play to determine the boosting point of a turbo system, such as exhaust turbine
diameter, turbo housing sizes, and then downpipe and muffler restrictions. Since
the turbo is not directly connected to the engine other than by exhaust flow itself,
boost is not a constant number per rpm like that ofa supercharger. For instance,
you can ...

2.14 SUPERCHARGING/TURBOCHARGING 2.14.1 Introduction As we saw in
Chapter 1, one of the ways of increasing engine performance is by increasing the
inlet density. This can be done by manifold tuning, as we have seen in Section
2.12.3, or by supercharging or turbocharging. Supercharging used to be the
generic term for using some mechanical device for increasing the inlet density;
now it is taken to refer only to positive displacement devices, and turbocharging
is used to ...

The GM performance parts LSX block is listed as “GMPP LSX” when referring
directly to that engine block. Also, when referring specifically to small or large
power-adders, I would use the mindset of “small” being something the original
equipment manufacturer (OEM) engine would handle. For N20 this would be 150
shot or less with the proper safety precautions and fueling. With boost, I would
classify “small” as what the supercharger or turbocharger kit does in off-the-shelf
form.

But with the turbo came the additional challenge of dealing with heat under hood
that is not present with the supercharger. “We wanted to deliver that big broad flat
torque curve that you can get with the supercharger,” says Stephens. “When you
drive a car, if you don't have a lot of displacement or low-end torque, it doesn't
feel as good as a supercharged engine. And that instant throttle response with a
supercharger feels pretty good in the Cobalt.” The supercharger GM installed is
an ...

While supercharging has been around since the earliest days of the automobile,
EFI allows more freedom in supercharger design, which has resulted in a growth
in the number of different styles of superchargers as well as a surge in popularity
of turbocharging. This growth is spurred by the ease with which an engine builder
can now control fuel. While Roots blowers have been around since the '50s, multi
-point EFI has opened the door for centrifugal superchargers and turbochargers ...

A1 is left of the surge limit. Therefore, in a two-stroke engine the induction of
additional air – for the optimum acceleration of the exhaust gas turbocharger at
the low end – has to be done via injection into the compressor (Fig.7.9). Only at
high loads, direct injection upstream of the engine is feasible. For a four-stroke
engine, the ... In order to solve this problem, a first possible method is the addition
of a mechanically powered compressor in series with the compressor of the
turbocharger.

FUTURE POTENTIAL The variable compression ratio (VCR) engine, pioneered
by Saab (which is now part of GM), is reported to achieve a 30 percent fuel
consumption reduction (equivalent to a fuel economy gain of 43 percent)
compared to a naturally aspirated conventional engine (GM, 2001). The Saab
VCR uses a supercharger to achieve the same power as a larger engine. Most
engines, in particular supercharged and turbocharged engines, must have a
lowerthanoptimal ...
