Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Shall I remove wind deflectors

Top post - not seen this before

Very interesting

I have Simmonds wind wings, beautiful, not very effective, and expensive.

But Duncan Charlton in the above link says:

"The solution was to fabricate a simple mount from aluminum angle, attach it to the side curtain mount knob..."

Easy to do and a smart solution if it works. Who have tested?

I know I've posted this before but why not make them removable ?

Here is a picture of Andy's from Lifes Motors 4 seater Roadster with a long removable pin/rod holding the deflector on - easy to remove when using sidescreens

The Simmonds wind deflectors are held on with 2 hex screws each side, so hardly a major effort to mount/dismount them.

I would be a bit concerned that a QD solution might result in them not being firm enough to resist the wind blast, and end up with them constantly swinging inboard and requiring adjustment, maybe?

The brackets/hinges prevent those type from swinging in any further than shown in the photo Tim. At least mine on RTA did...

Ah, of course. The Simmonds type are designed to swing all the way in so they can sit inside the sidescreens.

Just my personal experience:
I removed the deflectors and noticed increased turbulences so I put them on again. Not a big difference - but not a disadvantage to have the deflectors fitted.
And I like the style! 😎

Yes interesting post.
I don't have side screens or roof on my +8. Have used wind deflectors for a number of years and for me they do partially work. However, still get buffeting around the back of my head. Have experimented with a number of rear wind deflector options but never found one to work. So wear a flying helmet now for journeys over a 100 miles, but think you look naff!!

Today I visited my 93 old Mom, which means in total 220 km highway with speeds between 100 and 130 kmph, with the side screens off and wind deflectors on, this provided me an opportunity to experiment!
Me moving front and back--to "study" the distance from windscreen effect--must have looked strange to other drivers. However, for science one has to make sacrifices!
It is clear that shorter drivers have an advantage over taller ones (not because they sit lower, but further back: more turbulence). When I move forward/backwards, clearly turbulence decreases/increases. Also, the stream of air that comes into the cabin just back from the side mirror (as discussed above in this chain), can be greatly diminished by having one's arm just outside along the top of the cut away. I conclude that a flange like structure, secured like the side screens, could do the trick. I am afraid that one will not win a beauty contest with such balcony, but it should reduce the turbulence comming from there.
Another thing I learned is that, under similar conditions, Lindberg stick on sunglasses do stay on with side screens on, but blow off when they are not in position, and wind deflors do not provide enough protection!
There was virtually no wind today, so effects from driving only!
So far the experiments today!
Cheers,

So,one of the few situations in which there's a benefit to being a short arse like me!

I must admit to have concluded similar. Sitting closer to the screen does reduce buffeting.
