The above chart explains
Turbo-Lag
The secret is out ... now you know why even conventional ball
bearing turbochargers still have Turbo-Lag.
-
A 4" journal bearing is
requiring over two horsepower just to turn the bearing.
-
A flooded ball bearing is
still requiring almost one horsepower to push the balls
through the oil.
-
The answer is the
Aerocharger®
2.0.
It has balls rolling free in a
light mist of oil allowing almost all the power
generated by the turbine wheel to be directed to the
compressor to make boost.
Aren't you just a little envious?
-
The extra horsepower required
to turn a bearing is coming from the turbine causing
back pressure on the exhaust ... NOT good!
-
The bearing drag also
means less power to the compressor for boost ... NOT
good either!
The
Aerocharger®
2.0
has less back pressure on the exhaust
and more boost of the engine without noticeable Turbo-Lag
... life is GOOD with boost!
Graph below shows a
comparison of different forced induction systems coming on
boost:
-
The Advanced
Aerocharger®
-
Conventional
Turbocharger
-
Positive-Displacement Mechanical Supercharger
-
Centrifugal Supercharger.

All the units ended at the
same Max Horsepower . . . but one of them came on much
earlier than the rest!
Questions: Which one finishes the
quarter mile sooner?
Which one exits the corner quicker?
If you were on a snowmobile racing your buddies, who wins?
Come on guys, this isn't rocket science ... it's the
Aerocharger®
Now this is a Trick
Question . . . which one cost more?
Answer: It depends - the Aerocharger® 2.0
turbocharger cost more, it has more parts, tolerances
and specifications more difficult to manufacture to say
nothing of the space-age materials. But what is the answer
after you take out the waste gate, pop-off valve, oil lines,
coolant lines and consider the ease of installation!
Reliability?
The Aerocharger has spent hours on the test stand (in the
field), at high boost levels (ATVs), very dirty environment
(Sand Rails), long duration at full throttle (Snowmobiles)
and let's not forget the vibration test (H-D Motorcycles). I
bet you didn't know the Aerocharger passed a 1000-hour
endurance test by a major OEM or that it ran on a continuous
duty cycle for over 2 years on a specially modified military
piece of equipment.
