any technical bods know how much downforce (at at what speeds and angles if you know em?) of the WRC03 onwards spoiler, the one with the slats in it

thanks

lol the amazing knowledge of scoobynet

I don't have exact details, but I do know that it's far too much for a road car

I thought spoilers only had an effect over 74 MPH, which is why the Porshe ones pop up at approx that speed

Any spoiler (or in this case mostly wing) has an effect at all speeds, its just that its effect increases with speed. For a wing in clean airflow (so not on the back of a car!) it increases with roughly with the cube of speed (double speed = 8x downforce), mind you, so does its drag!

Why do you want to know, out of interest?

If its adjustable its more likely to be used to drastically affect mpg figures than actually do anything on a road car

The 03 on WRC rear wing isn't adjustable.....(prohibited by WRC regs)

lol how can it be too much? If you could find out cos google is not my friend today cheers mike

out of sheer curiousity, i remember somewhere ive got the escort cosworth facts somewhere and the difference between the whale tail and WRC spoiler were quite big, escpecially at angles. I just wanted to know the differences tht a few years have made and why exactly does it have to be quite so ugly

On a road car you want balanced aero at all speeds. Too much downforce or lift at either end gives strange and sometimes dangerous handling at high speed. Too much rear downforce at the rear will make the understeer at high speed which is fine until it's that bad that the car lowers itself too far and bottoms out or the wind gets under the front of it.

For a road car we trim the rear spoiler to give a small amount of downforce at speed bearing in mind that the shape of the body on most cars will give lift, hence they feel unstable at speed.

If you watch the rally car, quite often you'll see it fly nose up, sometimes to the point that it looks like it'll do a back flip. Richard had a huge moment in Australia (I think!) one year over a particularly fast jump for just this reason. This was because the spoiler gives huge downforce but the front lip stops working at higher rideheights, particularly when the wheels are off the floor.

so anybody creating a replica should be weary of this, such as the launsport car or do copies, through their copying process or just inusfficient knowledge of the design, lack any aero properties?

so the sti-04 spoiler on my car actually works to an aerodynamic degree? what sort of downforce does this create? I should 'hope' their is some data on this.....

So what about WRC replica kits? Does the front bumpers offer the same degree of downforce as the genuine article (like the cosworth front splitter) or would it be lost in the 'replication' and 'reproduction' process?

Oh and a last question....

when designing the car (as in the classic to bugeye transistion) did prodrive set any parameters for the car design? As in weight, torsional strength, length, height etc and all the other car technical specs? And (i presume you did) how far did you go in that design?

What about the aero and cooling packages? Who designed the final kit? Prodrive? Subaru or a 3rd party? Unlike mitsibushi ()was aethestics part of the requirments?

Do you mean like this one.



And there is not too much downforce for a road car because i use this on the road.

mmmm can i have more piccys of your car please? and where is yours from?

Pete Warburton

Why do you want more pics of my car?

automodellistagt

so i can look at it?

What did you think i wanted them for lol?

unless offcause its not yours?

Pete Warburton

Pete Warburton

Its mine alright.

Do you post on the SIDC?

automodellistagt

occasionally

automodellistagt

pete can i have a load of piccys of your car so i can see how the WRC spoiler looks without the rest of the kit? PM me if you want to avoid the normal scoobynet cronies :P BTW where did you get the spoiler from?

The rookie

All due respect to pete, but the latest WRC ones (which I have the pictures for - not sure about all in that style) have a much bigger angle of attack on the wing, so I'm guessing thats a copy made for road use?

Simon

chief-long-shin

Very silly question but i love these spoilers.

I may be saying a very dangerous thing here but would they fit on a classic?




Does anyone have any pics of one that has been put on there to either persuade or make me see sense


I sense i will be shunned from the world now for that comment

Gary C

Yes, and he kept the throttle pinned and was yelling like a maniac at the end of the stage

Pete where did you get this item from and actual cost if you dont mind. Cheers

Hi

Wanted to re-activate this thread. If Pete Warburton still posts here or if anyone else has a WRC replica rear spoiler like the previous pics of Pete's car can you please advise where you purchased it & how much it cost?

Also, what material was it made from e.g. FRP, etc and any problems with flexing / paint cracking?

Any regrets about fitting it? i.e Rear view, handling, etc

Cheers

If I remember this correctly, Pete bought the spoiler from someone in Scotland called Gumball.
And Gumball bought it from drmotorsport who had it on one of their own cars as a development spoiler.
I don't think Gumball has a Subaru anymore or where he is about.
