cold air induction

was looking on the net and found a cold air gun used in factories to cool presses. works off of compressed air, looked the gun up and found one that showed at 80 psi it took 70 degree air and made it -40 degrees. i know a blower motor dont have 80 psi but it does have 40 to 50 psi. and was wondering if someone has ever tried to put this design into an intake of spacer between the blower and intake? if so is there a website? a 110 degree change is alot with no moving parts, just off of how it moves the air. thanks for any feed back jeremy

 

I don't know anything about the gun but I know just enough about physics to tell you that it probably uses say 80 cfm of air per minute to make 5 cfm of air a minute at -40 degrees.

Again I am no physics major so these numbers may be way off in either direction but the point is there is no such thing as a free ride in physics.

sorry it was -30 degrees not -40 still very cool air and says the more air flow the better the gun works.

 

so basically an intercooler? which are illegal in pretty much all blower classes

 

maybe could be used to cool the clutch between rounds?

 

This looks just like the Clemco cooling tubes used by sand blasters to cool their breathing air. It works using the venturi effect of rapidly increasing the velocity and decreasing the pressure, creating cooler air. These have been around for 30 or 40 years. You might be able to design a huge version of this to move the cfm's we would need in a blower but it would probably be bigger than the car.

 

no such rules in mud racing. do you have a website for intercoolers?

I looked up the information on this systems efficiency since I could not give you an exact answer earlier.

Its efficiency is about 5 percent. That is the 200 watt unit needs 4 scfm of air at 100 psi, your average compressor that provides that kind of output requires around 1.7 hp or 1267 watts input.

So as you can see this system is great for the use for which it is intended
(cooling a very small tool bit) but it is far to inefficient for any use like an intercooler or cooling a clutch.
