The Rallyrific Roof Scoop
I've always said that I think a roof scoop would be
very cool but only if it's functional. I've seen countless ones at car
shows, none of which are functional, and all of which make me just shake my head
and think the owner must be a tool.
There's two reasons to have a roof scoop and only one applies to our cars.
Obviously if you've got a mid or rear engine car, you can use it for engine air
Otherwise, they're used to bring fresh air into the cabin such as most rally
cars have. This would be the function on our cars and doesn't have to be difficult
Basically you need it to draw air in and you need a way to seal it
As anyone who's ever had a leaky sunroof knows though, sealing it isn't a trivial
task. That will be a challenge in itself.
As for drawing air in; well that's not really trivial either. Unless you've got
some way of modelling airflow before you go cutting into your roof, the end result
is going to be a crap-shoot. If all goes well, you could get nice air circulation along the roof,
down the back window, and throughout the car. Alternately, you could have a gale-force
wind shooting straight down at your head.
In the end... if you want to do this, I say more power to you. If, however, you
just want to slap a fake scoop on the roof like countless other ricers... well go
ahead but don't act like you didn't expect it when people just make fun of it later.
