updates! first pic is of the standard bellypan that was on the car. this model fiesta is not sold with a belly pan. the belly pan is not even for this make of a car it has a audi and vw badge on it. this is how i bought the car. i took a peace of wood and coroplas and just cable tied everything together. the back of the coroplas is going to be trimmed to stop it fluttering and im looking into making some vortex generators off the end of it. this is not a full bellypan maybe 70 or 80% and it has been sprayed black since this pic just not fitted yet.
did some tuft testing as per image on the wiper blades. decided to get some more streamlined wiper blades and bend the arms of the blades so they sit closer to the windscreen and tuck behind the hood bit better. pic shows before and after position of blades and arms.
before of smaller blade
after. also the big blocks that they clip into have been trimmed down to the smallest profile possible. as mentioned in a previous post i trimmed the top piece of the wiper blades too.
difference between the 2 blade types. (not from same car)
longer blade tucked away. unfortunately i dont have a before pic but this was the biggest gain.
Grill block v1.2:
coroplas was covered in some black ducktape and cable tied behind the grill. openings were left on the right and left side for the air intake and a some cooling. however i decided to close the left smaller opening completely after the pics were taken.
there is about a 1 to 1.5cm or half inch gap between the top of the grill and the bonnet. i put a seal strip there so they can sit flush and the covered it in ducktape aswell. if you see closely you can spot the unevenness along the top of the grill. this will be improved some time.
final product
nice pic showing all the work. new grill block and tucked away wipers
once again i am not planning to go crazy with the mods like campacks or covered wheel arches, just simple easy things to help improve the general efficiency and most important keeping the car looking stock. so far gain with all these mods has been between .5 and .6l per 100km. looking forward to adding that bellypan!
