So according to some info I found 'round here that I think may have originally been posted by Aerohead (?), the cooling system or just the engine bay in general is responsible for about 30% total aero. drag. By blocking off just my upper grill I achieved (conservative first estimate) 10-15% increase in FE. It will be interesting to see if fully isolating the airflow from around the engine will actually increase my overall FE to anywhere near the theoretical 30%. I know I have a whole lotta work to do in fabricating what I want and also the testing testing testing.
Does anyone know if the SGII or UG can compile select data for a spreadsheet? The easiest way I know to determine if variables are effective is to show it on a graph and plotting by hand is super tedious.
As it's Sunday, I think today is a good day for cardboard mockups and a trip to the hardware store! don't tell my wife...
