HP server fan pressure test #1

Using a BMP180 barometric pressure sensor and a Coke bottle I am assessing the pressure one of these HP server fans can produce. It only makes about 0.1 psi over atmospheric pressure. Not thinking this will do much for a car's performance when used for forced air induction.

Thank you! This saves time to do some research. This is becoming a fad on small gasoline and diesel engines in Asia.

I know these things are 'stupid' for "real automotive use" but, I always figured these would make an appreciable difference on 'Small Engines'.
Every small engine I've seen is quite 'suffocated'. I wouldn't expect 'boost' but, I would expect 'some improvement'. Since, the HP Active Cool 200 can be found for $10-20 ea. it'd be a fun and cheap 'experiment'.

These appear to be HP Active Cool 200 cooling module fans. Any testing/work w/ the HP-integrated ESC?
If the HP 'stock' ESC could be 'hacked', one could get both ESC and fan for $10-20, rather than $30-50 for a 'kit'.

yeah.because an AXIAL FLOW COMPRESSOR it take multiple stages and a lot of blades per disk combined with stator but what if you change the fan into a CENTRIFUGAL COMPRESSOR?i guess this thing is only good for cooling the led lights on the car?

C OC or could be used to power an RC plane or a Dustbuster vacuum.

@@davidperry4013 1st thing that comes to mind (after 'crazy PC cooling') is a DIY battery-powered leaf blower. By-spec, 1 HP Active Cool 200 should be 'right up there' with your low-mid tier handheld batt.-powered dust/leaf blowers.
HP apparently had a higher-level employee interested/involved in Hobby R/C; old publications show HP was very 'open' about these fans being heavily-influenced from Electric Ducted Fan R/C (hobbyist) aircraft.

Hi Stephen, if we apply pressure mechanically on BMP180 will it sense it?

No
