Decided I would give some aero mods a go. So i went with the airdam idea and half blocked upper and lower grills.
I have no results yet as they have just been fitted.

This is before shot

grill blocks

airdam on, grill blocks painted

showing hows its shaped to direct air around the tyres

Ahaha yes! I love these cars. Looks like good work - I would focus more on getting the air to join back together more gracefully at the rear if I were you, but deflecting more air to the sides is always a good thing especially if you have moon discs or wheel skirts. Welcome to EM and keep up the festiva fiesta!

Yes a rear kammback would really help, may be some rear wheel skirts too.

Looking good and great start! Welcome to EM! Hope you get more inspiration the longer you're here.

I was actually looking at Festiva's before buying another high mpg car several years later.

My wife kept wondering why I was staring at the small parked cars in the restaurant parking lot while we were making our way inside.

Looking forward to your progress!!

Sweet! I'm in to see your gains to an already economical car.

121madness · 03-06-2010, 06:53 AM

ok so i got some better fuel economy results but i ended up doing more freeway driving than my previous fuel logs.
so there most likely is a benifit , just not as much as the results show which is nearly 11% ( i highly doubt)

EDIT
11% might be close actually because its 2 aero mods i done. problem with carby cars cant get precise data. but a gain is a gain

updated my fuel log.

nicely done.

i have a question though.

wouldnt you benefit more by actually blocking the grills in front rather than behind the entrances?
i would think that the air is still not flowing very smoothly over those surfaces?

anyways i would like to hear any updates.

Here was my upper block. Note the Aussie Capri

And here it was with the full air dam, this thing was ridiculous haha
