Have I talked about this before....

I understand......

this would be practically unfeasable. It was just an idea to spark conversation. How about coating the impeller blades and inner housing of the centrifugal supercharger with thermal coating. This would effectively halve the heat the inside the supercharger itself. The coating are extremely thin so there isn't a worry of clearance. I don't think. Maybe .001 would make a diference, but it may be as thin as .0001-.0005
The air into the intake may become lower than ambient temperature with the right intercooler. Especially if some type of gas is used. Now that right there is free power with no drawbacks.

RE: I understand......

Why would coating the blades with thermal barrier reduce the temp? The temperature increase in and forced induction setup is a result of compressing the air. Each type of compressor has a different efficiency, but you still have too follow Boyle's and Charles's Law (or the General Gas equation).

Because....

Coating the impellers and housing means the surfaces aren't as hot. So you would effectively reduce the temperature since the heat soakes the metal. The metal plays a part in maintaining the heat of the gas. Just like coating a piston top. When the intake charge hits the top of the piston it contacts a 600 deg. surface instead of a 1200 deg. surface. Same idea.

After all this bullshit just get NOS for a few hundered and dial in you HP gains.

More projects doomed to be over engineered and under built. This thread seems to be right up there with electric superchargers

This is more practical than Electric superchargers and is applicable.

Peltier Plates (electrothermal coupler or heat pump), I have 36 volt ones that can freeze dry ice. I also made a electrothermal exchanger for a class project and only sinks 7 amps at 24 volts, 4 at 12V and is able to produce a 25 degree ambient drop in air temp with 700cfm at 24 volt, 400cfm at 12 volt. Currents were limited due to condensation droplets getting into the intake. It can freeze the exchanger.

I have an assortment of the typical electronics gear head in my back room.

I remeasured it, and it is about half the size of a stock air box on a 91-93 lumy.

After all everyone has their ideas, and should expect some input, although it may not seem right to some...This is no reason to down right critizize a person for having it and make assumptions and comparisons to that which you know when the facts of a person ideas are purely unfounded to be anything of that comparison.

The only real temperature increase too the intake charge is a result of compressing the air, not from anything else. There is a minor amount of heat transfer down the turbine shaft, but it's minimal.

Perhaps for....

superchargers....but I have heard of this done on Turbos to help increase bearing life and cool down the charge. Heat is a huge issue for turbochargers.
