WTF is THAT!!!
Maddog, do you have any of these left?
Is anyone clued up with the technical side of underside car aerodynamics? Basically I have been doing a lot of reading about Formula one cars in the late 70’s with the discovery of ground effects. Most importantly the John Players Special Lotus cars. Anyway to cut a long story short is it possible to include this technology in a diffuser or any under tray that could fit to an Exige. I know it helps if the car is v close to the ground etc. The technique is basically an upside down aerofoil wing on the underneath of the car in a tunnel and then vented out through a venturi tunnel similar on an Exige. I don’t know if there is even enough space or if a lot of tiny upside down aerofoils would work or even make it worse. The effects were so great in the late 70’s that by 83 ground effects were banned in Formula One because of ridiculous cornering speeds. Ground Effects were still used in Le Mans and other various motorsports such as the 83 Rothmans Porsche where they found the best place for the ground effect tunnels were between the front and back wheels at the sides of the car. I don’t really know what I’m talking about it’s just from articles I have read but it would be amazing if replacement underside panels and diffuser could be made to use this effect that is basically so good at providing downforce its banned from almost all motorsport and so you dont really hear about it. Could something be done or am I talking rubbish?
The exisiting undertray uses those principles (although the body is too far drom the ground for what you’d call downforce)
There’s no real scope for creating deeper venturis due to the packaging under the skin - it’s packed in there pretty tight. You get S1 diffusers with longer (separated) tunnels to add a bit of stability and I’m sure the S2’s could be increased in size. It’s just grounding it out that proves a problem.

I’ll have some next week they are being dropped off at the anodisers on fiday and I will get them back next week.
I’ll keep one aside for you

as shug says these will improve stability a little, but I think most people buy them cos they look cool, in short it creates a low pressure at the back of the car and cleans up the air exiting from underneath the car.
Simon McBeaths book on Aerodynamics goes into it in great detail and its quite an easy read
…as they say…yo d’ man!..
I’m a no holes man and are they still �190?
is the fitting within the capabilities of a mechanical novice? or should I send it to plans to put on when they fit my new Zorst?
many thanks
fitment is really easy, no need to spend money getting someone else to fit it, unless of course they do it for free when they fit the exhaust
they are �190 + �20 postage and packaging (its a Big Box)
have sent you a pm with my address etc… thanks
Will the diffuser fit the same as the std one against the number plate suround and mesh , also the Exige S that i have now has extra fixings along the back edge of the defuser than on my NA 04 Exige, is there an option on fixing slots ? Thanks.
A word of warning; cars with LED rear lamps not only have extra fixing holes at the rear, some of the older holes have been moved by a couple of cm.
I have had them fitted to s2 elises and exiges up to 05 reg, not sure about the additional holes on the cars with LED lights. sorry I couldn’t help more
Can’t wait to get mine fitted!!!
Can’t wait to get mine fitted!!!
Sent yours and Jimbers45 on Friday, should reach you guys by monday
had a few done in Silver (Satin finish) aswell if anyone is interested
thanks Dave. Look forward to showing you the finished article.
did you ever move forward the front splitter?
I have a broken front splitter but not got round to modifying it yet as things have been a bit manic as we’re moving in a couple of weeks
Picked mine up yesterday, cheers Dave.
I will get it fitted sometime this week and post a piccy.(sure it will look great along with the new exhaust!)
