Spool Turbo With Water?
#1
Hi,
now don't shoot me, but i got a strange question:
would it theoretically work, to inject water into the exhaust manifold, to spool big turbos? the injected water would become steam and thus expand rapidly. that would be a kind of antilag, or am i missing something?
i said theoretically, because you obviously would have to work out something special, since you can't just screw in a water nozzle in a super hot manifold and expect it to work.
but what about the idea itself?

i think the sudden drop of temperature will greatly slow down the exhaust air because warm air moves faster , and also, it will make the exhaust gas more dense, so whatever expansion the water will make will make the exhaust more dense.... i could be wrong though

When you inject water into the exhaust it will boil and increase the manifold pressure and decrease the exhaust gas temp. This will allow the turbine to extract more work, however the increase in manifold pressure will also mean increased backpressure on the engine.
This will make for an interesting thermo problem. What is the typical flow rate and pressure through the manifold?
