Here's a small snippet of data taken from a part of the course that is relatively flat (so pressure should be related mostly to speed and not elevation). It seems the pressure sensor's resolution is in 1/100th's of an inch of mercury... so it's a bit "discrete". In any case I think it illustrates how pressure behind the intercooler drops with increased speed...

Note that the pressure sensor is behind the intercooler and a few inches above the engine's valve cover (see http://www.lotustalk.com/forums/atta...calibrate1.jpg)
