Re: What does a spoiler do?
I need more grips myself! Tire! Tires! Tires! But the price for tires is
an exponential curve but the frictional gain is incremental. I was
thinking of racing with the Falken Azenis next year but decided to stick
with the Kumho Victoracers.
Anyway... I didn't realize those are all AWD's now.
The examples I brought up was merely to show that FWD vehicles benefit from
rear spoiler since someone had mentioned that many vehicles with rear
spoilers are FWD cars.
Other examples of FWD vehicles that have big rear spoilers are the Realtime
Integra/RSX Type R's, the Mazda Protege, and Sentra SE-R are all winning
vehicles in the SCCA touring car challenge.
As for my EVO - lovely car! With 320 HP at tapped - it's a clutch burning
fun! I have not messed with the upside down airfoil in the rear end but the
angle of attack adjustability is a nice thing if I ever race it someday.
For those who have studied aerodynamic you'll recognize this formula:
L=1/2pV^2SCl
L=lift
p=density
S=surface area
Cl=Coefficient of lift
Noticed that velocity is squared. Yes you'll get expotentially more lift at
100 MPH than 50 MPH but as long as you have airflow going through the
airfoil you will get lift. It has been 8 years since I was last in an
aerodynamic class so please don't quiz me on it. Notice that if you have
more surface area, you get more lift. This is why you see those AM SCCA
cars with double or triple decker spoilers that is sometime bigger than the
vehicles, it must work because they sure produce really fast time around the
track.

Re: What does a spoiler do?
I need more grips myself! Tire! Tires! Tires! But the price for tires is
an exponential curve but the frictional gain is incremental. I was
thinking of racing with the Falken Azenis next year but decided to stick
with the Kumho Victoracers.
Anyway... I didn't realize those are all AWD's now.
The examples I brought up was merely to show that FWD vehicles benefit from
rear spoiler since someone had mentioned that many vehicles with rear
spoilers are FWD cars.
Other examples of FWD vehicles that have big rear spoilers are the Realtime
Integra/RSX Type R's, the Mazda Protege, and Sentra SE-R are all winning
vehicles in the SCCA touring car challenge.
As for my EVO - lovely car! With 320 HP at tapped - it's a clutch burning
fun! I have not messed with the upside down airfoil in the rear end but the
angle of attack adjustability is a nice thing if I ever race it someday.
For those who have studied aerodynamic you'll recognize this formula:
L=1/2pV^2SCl
L=lift
p=density
S=surface area
Cl=Coefficient of lift
Noticed that velocity is squared. Yes you'll get expotentially more lift at
100 MPH than 50 MPH but as long as you have airflow going through the
airfoil you will get lift. It has been 8 years since I was last in an
aerodynamic class so please don't quiz me on it. Notice that if you have
more surface area, you get more lift. This is why you see those AM SCCA
cars with double or triple decker spoilers that is sometime bigger than the
vehicles, it must work because they sure produce really fast time around the
track.
HAPPY NEW YEAR EVERYONE!!

an exponential curve but the frictional gain is incremental. I was
thinking of racing with the Falken Azenis next year but decided to stick
with the Kumho Victoracers.
Anyway... I didn't realize those are all AWD's now.
The examples I brought up was merely to show that FWD vehicles benefit from
rear spoiler since someone had mentioned that many vehicles with rear
spoilers are FWD cars.
Other examples of FWD vehicles that have big rear spoilers are the Realtime
Integra/RSX Type R's, the Mazda Protege, and Sentra SE-R are all winning
vehicles in the SCCA touring car challenge.
As for my EVO - lovely car! With 320 HP at tapped - it's a clutch burning
fun! I have not messed with the upside down airfoil in the rear end but the
angle of attack adjustability is a nice thing if I ever race it someday.
For those who have studied aerodynamic you'll recognize this formula:
L=1/2pV^2SCl
L=lift
p=density
S=surface area
Cl=Coefficient of lift
Noticed that velocity is squared. Yes you'll get expotentially more lift at
100 MPH than 50 MPH but as long as you have airflow going through the
airfoil you will get lift. It has been 8 years since I was last in an
aerodynamic class so please don't quiz me on it. Notice that if you have
more surface area, you get more lift. This is why you see those AM SCCA
cars with double or triple decker spoilers that is sometime bigger than the
vehicles, it must work because they sure produce really fast time around the
track.
HAPPY NEW YEAR EVERYONE!!

The reason they benefit is because those spoilers are meant to "spoil" the lift
that the body shape creates at speed. They are more stable at speed with a
spoiler. Thats why Audi had to retrofit all the original TTs with an automatic
spoiler, they were found to be unstable at high speeds. Has nothing to do with
traction in that application.

They have to be that big because of the speed at which a typical Solo II is
conducted. Even an A-mod on a very open "Nationals" type course will rarely get
over 80 mph, which is about where a typical wing becomes effective.
As an interesting aside, I used to tow a Formula Coninental on an open trailer.
I noted that it sure towed hard for an 1100-lb car on a relatively lightweight
trailer. Then one day I got about 2 miles from the house and decided to stop and
take off the rear wing. What a difference! It was like I had been driving with
the emergency brake on. Made the trip to the track a lot more pleasant after
that. for all the downforce the make, they also produce a lot of drag.
Nothing's free.

Ah, but don't forget - the coefficient of drag also increases as a square of
velocity - so the faster you go, the more drag that wing is creating. The
more lift created by that wing, the slower your top speed.

Nope. The COEFFICIENT of drag is independent of speed. The actual DRAG
is what increases with the square of velocity.
