The biggest rear wing I've ever seen

[AMST09]

Back to the OP, I've seen it driving round welwyn garden quite a few times recently

He has competition...

Or that there's a reason for the phrase ''Slicks and Wings''. Wings and ditchfinders is not so wise.

That is sexual.

Not the biggest but it does have a certain something...

Talking of which, have you seen the gearstick housing on marc's S1 Exige? Truly a work of art. Now that is how to engineer a car properly....albeit I appreciate that is more of a money no object build.

Got a link? Im planning to put a mini-fire extinguisher in the vacant bit under the mech.

Has a purpose, gets used, is purpose-built and has ample power. Looks silly, goes silly fast. Winner.

Wrong way up?

You're clear for take off cap'n

(I know its actually proper - but the photographer had one job - "Roger told me to show off the car's speed and downforce...")

Bigger than this?

I would love a drive in that lotus...sad to see it burnt out.

The biggest wings in an actual, real racing series has to be from the World of Outlaws Sprint Car Series in the USA.

[2172cc]

Still not been able to find a picture of the car I saw in the original post but impressed with the level of wing development going on out there.
Time Attack seems to be where its at........

I wonder how much of this actually works?

I was wondering that myself and the wings on the sprint car. Not that I wish to denigrate the things but just how effective are they?

[Digitalize]

Considering how competitive Time Attack is, and that any wing adds drag, thus slowing the car, I'd imagine any added piece of aero they feel is making a difference to the downforce. Cornering speeds are ridiculous in the top tier of Time Attack, really is impressive to see.

[ikarl]

are (really) large wings ok if they've been wind-tunnel tested? and proven to make a positive difference to the car?

I agree, although not wind tunnel tested (because ££££) I imagine their aero is effective, when you see the cars doing ~55 second laps at the Tsukuba Time Attack!

I believe this holds the current record - Under Suzuki's carbon bodied S15 Silvia:







You'll have to excuse my ignorance of aerodynamics but the way I understand it is - the faster you're travelling, the more downforce is created. For example you hear of supercars with a (relatively) tiny wing producing 300kg of downforce near it's top speed.

So I'd assume to produce anywhere near that figure on a lower speed circuit like Tsukuba, hillclimbs etc, you'd need much more aero - more surface area and higher angles.

(Snipped picture)

BriSCA F1 is pretty close to that, tarmac more like the World of Outlaws but shale wings are something else!

[SonicShadow]

Time Attack, you say?

[KarlMac]

I know the time attack Evos such as 'Black Mamba' and SVA's car have their Aero properly developed using cfd/computer models, not sure how much physical testing happens but they do a lot of data logging so would have some baseline to decide if its working or not
