BIG SPOILERS and TOP SPEEDS

[weight]

Any comments.............???

 

[BenR]

um, they dont go together.

it is possible to create downforce with minimal drag increases, but you generally have to have an f1 car on the drive.

 

[weight]

ok, what im getting at, how big a reduction of top speed do big spoilers have on road cars??

I know its a insanely hard question to answer as there are so many variables (gearing/torque/spoiler size/drag)

but could a quite large spoiler reduce top speed from say 135 to 115??

 

[BenR]

yes.

Not to mention that the actual increase in downforce will not be outweighed by the increase in drag.

Not to mention the fact that amatuer aerodynamics can serioulsy affect how a car handles at speed. you could end up with a light front and sticky rear.

sounds messy

TY

 

[BenR]

TY????

yea, it wont help really........since ligt is generated over a cars whole bodya nd there is a singular point where the higers lift is felt, so youd have to find that first.

 

[weight]

TY = thankyou

and, i have no idea what u just said........lol

 

[BenR]

oops, my spelling!

revised version!

since lift is generated over a cars whole body and there is a singular point where the higer lift is felt, so youd have to find that first.

 

[KDF]

higer lift ?

I thought this was the revised version ?

 

[weight]

lol

 

[BenR]

DOH!!!!

aint you guys nevere heard of higer lift!!??

come one, its only the singular polar moment of inertail bi tortional negative pressure differentials!

 

[weight]

oh! that higer lift!!??

So basically what youre saying is that the Suzuki Escudo Pikes Peak spoiler I fittet to my Cup yesterday is going to loose me top end speed! Why was this not documented with the fitting instructions?

LOL @ Frosty! Looks at the size of that thing!!!

 

[Mike Wright]

LOL @ frosty! Bet the driver thought he was driving a F22cross!!!!!!

BenR surely you are forgetting a mulitude of combinational factors such as inviscid flows; potential flows; vortex motion; Aerodynamics of airfoils; viscous flows, boundary layer theory, transition and turbulent flows. .......LOL

 

[BenR]

didnt i mention them?

 

[McBunny]

such a nice car that got to see it a few years ago at the motor show it was bloody huge

Someone please post that pic on the Saxo forum!!!!!
