Part 1
Hi Mayf,
I read a lot of opinions to your spoiler issue.
Let me explain something to "spoiler"
Turbulences - if they come from a roll cage or something other is in the first
view uninterested.
Issues which you have focus on, are:
1. how is the spoiler mounted to/on the vehicle
2. what kind of profile you like to use or you have to use
3. what kind of effect you like to get
4. how is the basis balance of the car
Depense on the kind of spoiler you like to use, you have to know where the air
has to go behind the spoiler - sounds funny but this is important.
If you like to have a spoiler like Keith on his racer, you have to check how
long can be the side pads - means the left and right upright closing pieces.
If they can be designed very long, the angle of the spoiler can be lower, with
this you reach the same pressure with less speed reduction as a configuration
with short side pads and a high angled spoiler.
Next point is, how is the "flip" on the top end of the spoiler designed,
depends how this flip - if you got one - is designed, you get different air
flows behind the car. You need a air flow which match to the air flow which
will be create by the shape of the car. If you get a different air flow the
mix of this air flows will effect the driving of the car.
