Magnehelic® Differential Pressure Gage

I've had one of these sitting around in the garage for a few years and wonder if anyone on the forum could suggest a use for it in evaluating possible aero mods to my Solectria Force. (97 Geo metro 4 door body)

My thoughts are that it would be educational in determining the pressure difference between various locations on the vehicle at different speeds and after and before mods.

Any recommendations or insight would be appreciated.

I didn't find any threads doing a couple of simple searches.

Thanks

You can do lots with that Magnehelic. Look at the following:

If you can come up with a copy of Paul von Valkenburg's " RACE CAR ENGINEERING it will show you a bunch of things you can use the MAG for.
They can also be used as an airspeed indicator ( 1-3-inches is a good scale ).You'll have to re-face the dial.
Dwyer makes some nice pitot tubes and they also make a wind-seeking head which will allow for relative winds ( important with vehicles ) which a fixed pitot would not.
