Correct position of front lip
Discussion
Morning,
It's mainly for stability at higher speeds. Nothing to do with forcing air into the rad and it should face forward not backwards and should be mounted towards the back of the nose just like the pictures of Simon.b's griff from the thread link above.
Hope that helps.
cheers

I'm going to disagree with Reeso on this. I don't have my car at the moment but I'm fairly sure it's best mounted a little further forward than shown, but behind the rad intake.
Whether inadvertantly or not, it does aid lower speed cooling in my experience so it is worth having - cheap as chips to buy too. TVRPower have just put a new aluminium one on for me after I broke the fibreglass one what was on there

Actually it was fitted to aid cooling not stability, that's why it's mounted just in front of the chassis on the underside of teh body.
Have a look at this on Dave Spensley's page if you fancy making your own

The lip creates a zone of negative pressure behnid it and so sucks air through the radiator. It actually does work as when it's on it stops the bonnet flapping up and down at the front at speed as it sucks it down (oooh Matron). Any other aerodynamic benefits are co-incidental.
ETA I actually think Dave's is a bit too far forward and should be right on the edge as shown in the picture in the link above, that's where mine is when I haven't knocked it off.

Heres a pic of mine as fitted to my Chimaera. Its main purpose is to create negative pressure directly behind it, as this helps to draw heat from under the engine bay, hence the added bonus of keeping the bonnet from flapping at higher speeds. I have driven the car without it fitted [it got ripped off by....yes you guessed it a speed ramp] and the handling of the car was no different. Definetly helps to keep the under bonnet temp down though.

You're all wrong, rubber is the only way... Strong enough to cope with wind pressure yet flexible enough to deform over speed humps

My Griff hasn't had a splitter fitted whilst I have owned it but it is obvious that it has had one fitted in the same position as shown on the photo posted by RichB.
Mine has twin fans sat on the radiator and when on they pull cold air through the rad from outside either from the front or the aperture under the car in front of the splitter. The warm air then exits through the gap between the front of the bonnet and the body. When I fit a splitter it will be as shown with the lip facing forward to force more cold air into the rad.
Do Chims have the apperture under the front of the car? I wouldn't have thought it was needed.

No there is no aperture, but the rad on a chim is vertical,the only air for the rad comes right thru the front, but the splitter in creating negative pressure behind itself, helps in drawing the hot air down and away under the car. This all seems a little improbable but having run with and without one fitted, the chim is cooler under the bonnet.I only posted the pic just to show that it should be facing forward.
