They top is a turbo, bottom is an SC.

Both completely awesome!

 

How did I miss that? :lol:

It would be so awesome to get one of those aircraft modified ea81s. :slobber:

I would take the supercharged one, it looks like it would fit in the engine compartment better.

The SC one would probably work better for a car anyway, probably has better torque curve.

 

With that gigantic turbo it would have AWFUL lag. Probably doesn't make power until around 4000. Which is perfect for an airplane, spool is irrelevant. You run it up and leave it there until you land. But on the street it would be like driving a honda :P

As I understand it with an aeroplane, this turbo setup would be used primarily on take off. Not in use much of the time otherwise.

No, actually. Air is thinner the high up you go.

Take an N/A engine. At lea level there's at atmospheric pressure of 1bar, or about 14.7 PSI. Go up to 10,000 feet and there's only around 10 PSI of pressure. That means less manifold pressure, that means less power output.

 

Turbocharged airplane engines have a unit called something like automatic density controller to keep the same manifold pressure at all altitudes.

So at lea level maybe the turbo is putting out 5lbs of boost, at 10,000 feet the turbo has to put out about 10lbs of boost to produce the same power.

 

So yes, it would help greatly taking off from a high altitude airport. But the point of the turbo is constant engine output at all altitudes.

The turbo does, in fact do work when flying.
