Oh boy! Neil you are breaking almost all records with your xA. Sorry I was dragged into too many things and could not get back to my xA's mods. Recently with Dallas's 100+ degree adventure for continuous 41 days and my AC running full speed all the time has reduced my mpgs to avg 36 mpgs. I also took away upper grill block to make sure my car can survive the heat. (It may not have been necessary but as a precaution I did it.)
To answer your old question my car does average around 2500 RPM near 60 MPH.
I was wondering instead of creating a bottom pan for covering the parachute/read bumper can I make holes into rear bumper and apply a grill to let air out. Will that really make any difference?
