Has anyone ever made a front splitter and actually seen any difference in handling?

Anyone ever made a front splitter?

Never noticed a difference between splitter and no splitter.

Have you got any pics of it rob?

Correct Tom, I made this one. Made from HDPE with stainless tie rods.
I think you did it first. The lines of yours look better than the orange one.

Cheers mate, I was and talked the other guy through how to make the orange one and where to buy the tie rods from.
See picture below, the subframe tensions it across the car by pushing it down slightly, it doesn't weigh very much at all. I've paired it up with some home made carbon arch liners too. (Front sections only).
Only picture I could find sorry...
Msphotographic I think...

those look cool!!!!!
are the just attached to the bumper?
is the bumper strong enough to deal with the forces?

Hey yer the black bin wagon is mine, im sure iv some piccys il dig out.mines attached onto two existing holes on the sub frame

Iv got this design on an cnc template and one that isnt as big which il be having made over summer to see which I prefer

They look good, its close to becoming a how to article for the members section ;-)
Any chance you could recommend the gauge and dimensions of the material you used, and where you sourced it, and also the hangers?
Are there additional fixings underneath, a pic would be great?
Cheers

All well and good and looks like a couple of good quality pieces of kit but do you really benefit on track with either of these? Have you carried out any lap timing with and without and noticed an average time saving across a lap?
just curious

There will be improvements from having something like this fitted as it reduces the amount of air flowing under the car generating lift. For it to be really effective though, it needs to fit as close as possible to the wheels (obviously allowing cut outs for full lock) and ideally be coupled to a flat floor and rear diffuser.
Bi? Lol

Addressed!Lol. Addressed.
You need to sort your Occupation out in your profile

I understand the principles behind it (discoveryHD haha) but a lot of people seem to bolt things to there motors with no real evidence how it has reduced lap times etc.
As the for the sexuality reference.... Team Mincing Racing says it all haha

Doubtful as you need to test it on the same day, same track, same conditions, same consistency of driving style, etc etc.

If I was designing such a item that would be my idea of testing.
Set a number of laps without it fitted to gain a average lap time and then same again with it fitted.
Same track, same day and same conditions fingers crossed but guess you can always rely on british weather.
download and read aero insight in trackdriver magazin editions 14 ,15 and 16 i think ,
http://trackdriver.com/trackdriver_shop/shop/issues.php?c1=Magazines
if i can be arsed?find the time , i'll scan them and upload for you .

Find the time haha
This picture is so apt.
Unfortunately aero is so impossibly complicated it's barely worth guesstimating. Particularly with no satisfactory way of verifying performance.
Sufficiently accurate testing will be extremely challenging so I'm interested to see what you come up with!
Track days scream of placebo, gaining experience lap on lap, natural variation in lap time, traffic, different lines, bumps, evolving tyres, no data, better balance not necessarily outright grip etc.

You need a wind tunnel or use a dynamic design modeling program.
The only way to see whats going on.
Aero is worse than geo to get right

This is what I would expect, as said the principles behind the idea prove that spillters, under trays, diffusers and spoilers all work but race teams and manufactures spend millions in development and design on this things.
There's clearly more to it then bolting on some plastic.
It is very easy to add a splitter which to all extents and purposes looks "about right" and does increase downforce on the front axle, but actually reduces the total downforce of the vehicle because it disrupts the underbody flow which in turn disrupts the wake and the roof line flow.
Unfortunately cheap (and not great IMO) CFD seats start at £5k and being able to use/interpret it properly is something money can't buy. Well besides consultation. You know what I mean.
Oh my point entirely, I was just trying to be less defeatist/realistic to minimise the danger of being flamed :rasp: and to not appear an engineering geek by using all my longest CFD related words :rasp:

And this is the very reason why I'll never bother with it!
I have played with splitters diffusers and spats on my carbon westfield , yes they had a measurable effect but there are many other issues to consider , as to do it properly you want a total flat floor ,and then you get into cooling considerations.
We had the constant issue of the carbon diffuser creating downforce but pulling itself down due to mounting issues
Absolutely.
PHD/industry research is starting to get to the bottom of roll centres etc with derived maths. In the mean time (using ye olde roll centre theory lol) we can make pretty damn accurate simulations with maths/physics/equations that go all the way from the start to the answer.
Anything in aero is just giving a computer a (very clever) set of rules and getting it to approximate where every individual "piece" of air is and then go back and check every "piece of air" is in the correct place before approximating where it will 0.01 seconds later! Then repeat that till the cows come home and most importantly make lots of colourful pictures of vortices and pressure distributions to stick on the front page of your report!
On a more constructive note if you really do like DIY, it's much harder to go wrong with a basic diffuser than with a splitter. But watch out for the hot exhaust on said flat floor. You will also scream "britcar" or "time attack" if you turn up with an aluminium sheet diffuser.
Of course you could pay lots of money to have a consultation company develop a lovely optimised relatively-issue-free aero pack for your clio :rasp:
EDIT: type far too slowly these days, beaten to the flat floor comment.

Fortunately developing a 7 type car means less issues with exhaust as its out the side from the primaries
Home made carbon splitter
Temp issues that were a concern were rear diff and gearbox , even witth 2 low pressure ducts in the floor
And just because 3 different carbon weaves against the nice green of our sport 160 at the time

ill just pop down to my local wind tunnel, for an hour or two ... I have a spare £100,000 lying about ha....
