Alex,

A couple of guys at NYLOC have tried to conquer this problem, I have talked to them about it as I was thinking of doing the same "mod"
One answer was to use an MGF (I think it was) deflector, my mate had to make up some brackets etc to get it to fit in. He reckons he has a good fix.
The other answer although you have not got a roll bar ( which I have ) was to use some 2.5 mm micromesh from http://www.norfinenets.co.uk/netting/netting.html this company, using velcro strips to fasten it to the roll bar. Again it is said to work quite well.
I am sure with your "Elan skills" you could make a collapsible frame to house some micromesh.

Regards,

Doug.

P.S. Will keep an eye open for your Elan at CLM 2010, alas I will not be in my Elan this year. I'll whisper it, Elise instead
I will be in the Lotus parking area though.

Hey fellas
You don't need much to make a very effective wind blocker for your elan,
see link to previous posting some months back.

Thanks everyone/ Doug.

I can't get the link to open in that post and the picture is quite small. Saving and zooming just destroys the detail but It does look to be a neat solution. Anyone with a bigger more detailed photo?

I have saved the details regarding the netting and another big thanks for that head up...That is exactly the right material. A nice frame from light alloy now and a good method of fixing and job done.

My mate with the Daimler dart is looking to make the same, so we can compare & co-operate with design and welding etc, & we are both thinking of doing a welding course to improve our mig/tig skills.

Pictures of the wind blocker for elan...note that this design suits an S2... later models may differ.
I built the blocker after being blown to bits from several hours of blasting around the alpine roads in th elan,
works well to... gets rid of about 70 - 80% of the wind buffeting effect....yeah. I'm getting soft, but
hey, we are allowed a bit of comfort aren't we?

And that is exactly why I want to make and fit one. Why not if it makes our car more usable and comfortable/quiet.

Great pics and info.. many thanks Col.

Just a thought whilst I am twiddling my thumbs.... Do you (anyone / All) think it might be possible to utilize the tension hoop in the existing hood frame? If this was able to be 'braced' in the up position with all the hood stowed and cover on, all that would be required would be the attachment of the cloth netting. It might even be possible to make the attachment of same permanent. Looking thru' it with the hood up is not to big an issue. I know this 'caus my wife's car rarely has the screen removed and stowed.

Just a thought... Probably talking tosh again which I will find out when I go and look at the car. Which is nice n comfy below its cover awaiting salt free roads. :wink:

Roll on summer...

Alex,
I have not been on here for a bit and just saw the thread. I made one from some plastic sheet from B & Q as a trial. I fitted it onto a Spyder roll bar with Velcro straps. It worked well in general and stopped all that air around your neck that makes you neck stiff the next day.
However, the wind found new places to get into us. This was around the arse region. The difference was that the pressure had increased and I got a savage velocity around my lower back and bum region. Then had a rug around my behind. In the end I gave up and took it out. I settled for keeping my window down, a bit, and blasting the wife. The window down tends to help. Call me an old tart, but I wore a hat (she did to) and had my fleece collar up. Even when the sun was cracking the flags.
To be honest, I think some people are more susceptible to drafts. Even the tough wife got a bad neck by going bare necked in 27 degrees C. She had laughed at me. I am talking about proper days out, runs of over 200 miles plus. Not around the block and back.
My DHC Elan has gone now and it did spoil the enjoyment. I don?t know whether the actual roll bar helped mess up the air flow and make it worse. I never drove it without a roll bar.

I made a wind deflector for my Elan that fitted on to the hood hoops. It worked but was clumsy. I can post a photo if you would like. I now have a system that is made from bits of alloy tube from B&Q! and a screen that velcros on to it with poppers around the rear. Whole thing fits under the folded hood when not in use. If you would like photos just ask and I will take the camera out to the barn..........................


PS I may be a softy but when you do over 800 mles a day with the roof off a bit of extra comfort does not go amiss - and I can hear the satnav lady.........

Does that mean you have a lot of people going over your head ?

Thought I would bump this topic up as I have just completed a prototype wind deflector for use with a Spyder roll bar, first results are very encouraging as there is very little buffeting or wind in the back of your neck up to 60mph. The fixing bolts are elongated as I'm experimenting with different angles at the moment. Once I've decided whats best I will use some black plastic nut covers to tidy up the fixing point.

It's made from 6mm clear polycarbonate "Lexan" and is edged with Woolies rubber window trim for 6mm glass. Fixing to the roll bar is via the 9/16 threaded inserts at the back of the headrests. It stays in place with the hood up and doesn't interfere with it's operation, just means you can't use the parcel shelf while it's in place. It's very sturdy and rigid with no rattles or squeaks and apart from the fixing bolts as explained above looks very neat in the flesh and almost original equipment.

Alan

Does that not create a buffering effect on the motorway? The dynamics of wind direction within the cockpit at motorway speeds must be all over the place, which is why most OEM wind deflectors are fine mesh, thus allowing somewhere for the wind pressure to be dissipated?

Any way, it looks a neat solution. The Super Sprint Targa!

Hi Tim,
I borrowed the idea from those that are available for Porsche's, . On the S4 there's actually plenty of free space behind the door frames down to deck level before you get to the deflector, so this allows equalisation. I still need to test it above 60mph, but any convertible whether it's fitted with a wind deflector or not is going to be pretty noisy and draughty at motorway speeds.
