Aperta Windscreen install on a VS Speedster

The third picture was taken before the lower screw was installed on the bracket. That lower screw stabilizes the bracket so that the pivot point for raising or lowering the screen itself is at the junction of the screen and the bracket, not the bracket and the car.

Bob - how about a link to the place you bought this?

Hi Bob.  Will the top completely go up and latch with the wind screen in place?

pkdfw:

I removed the roof before the install. If my measurements were right, I simply have to lower the windscreen to accommodate the roof being up. That would be more for visibility out the back window than anything else.

@Panhandle Bob, what keeps it from rotating around the bolt attaching the screen to the bracket when in use?

Michael:

Friction. You just crank down on the fastener.

Thanks Stan.

Bob........What is the material of this windscreen ?  Plexiglas ?  Screen ?..........Bruce

Bruce:

It is a very tight fabric mesh on a round aluminum frame.

The mesh has some give to it, but is stretched tight on the frame. There is some visibility through it.

I can take some close ups if you would like.

Bob......No,  that's ok.....I was curious if it was screen or an acrylic sheet.  My guess is that the screen allows a little air to pass thru and thus eliminate the slight  "buffeting" or "fluttering" that a solid acrylic screen does at specific speeds unless it is fastened down fairly well..........Bruce

Correct, Bruce.

When you drill into the sides inside the car (behind the seats) to mount the brackets, what type of material is that?  Is it metal, fiber compound of some type, or something else?

Thanks

I don't understand the question, sorry.

But let me try.

I drilled through square weave carpet and the fiberglass body, forming a pilot hole. Then I screwed in the mounting screws. It is a very sturdy connection.

Is that what you wanted to know?

Thanks Bob.  Yes you answered my question. I was wondering what the material was and if it would be strong enough to hold the windscreen with all the wind.

I haven't picked up my VMC speedster yet, so I don't know what the inside panels are made of.

It's all part of the fiberglass body back there. If you bought it with a carpet kit, then it probably covers all of that area. On mine the fiberglass is pretty robust and thick in that area.

Bob,

I'm curious what your thoughts are after taking a drive with the screen installed. Is it markedly quieter in the car? I've never taken a ride in a convertible that had a screen installed, so I'm curious about the benefits. It would be nice to be able to hear the stereo better.

There is a decrease in noise and turbulence, but not as much as I expected. I don't have a radio in the car. I'm guessing a 50% reduction.

I have a pretty loud sidewinder exhaust that dumps behind the passenger as well. I'm looking to have it plumbed to a center rear exhaust, and that might reduce some noise as well.

Stan told me that he runs his with the windows up and the screen in place on his IM and it makes a big difference. Being a VS, to get a similar effect I'd have to put the drop in side windows in, and I haven't done that.

Your "moderate improvement" does not surprise me at all. The windscreen is only half of the equation. You've got to get something for the sides as well.

This is where Troy's "Cruzin' Windows" would make an enormous difference. Something full-sized in hard acrylic like Lane had in his red car would work even better.

Bob, most of your "exhaust noise" is coming from those big Dells. A lot of people expect a noise drop with a muffler change, but the lion's share actually comes from the intake.

That's quite true.

I installed a pair of "Turbo Hats" and the intake noise got quieter.  Not a lot, but certainly noticeable.

Danny:

That's a sound I can live with!!

I think I've figured out how to easily redirect the plumbing to the rear without messing with the overall exhaust system. I like the look of the center exit exhaust as well.

I found that on my Speedster that just turning the exhaust tip down towards the pavement helped make a noticeable difference..........Bruce

Eh - it's wind buffeting that I want to avoid. The exhaust/intake noise is music.

I can’t speak to a Speedster, but I can listen to the radio on the freeway with the wind deflector and the windows rolled up in my 968. Much like a sunroof in a coupe.

Speaking of Cruzin Windows, Jack, the fellow that owned and restored Dean Jeffries’ Carrera posted this pic of a custom Karman Coupe from Amelia Island. Among the many nice touches was this side window carrier.

Also had a Polo motor in it.
eta: Someone else found a link. Pretty interesting read.

@dlearl476 nice 944. How are the screens installed in the 944. Are they foldable/collapse when not in use ?

It’s a 968, but the interiors are the same ‘86<. (And they use the same screen)

There are two L-shaped bars on each end that fit into holes in the rear shelf area and elastic straps and bars that go against the trunk access panels.  It folds just like the Aperta one, it just has factory mounts. Sorry I don’t have a better picture. it does fold flat. And it talks all of 5 minutes to put it in or remove it.

Mine is a little different than this one. Rather than the “W” shaped support, it has two straight ones that fit into the corners of the cargo shelf.

See that plug? The windschott comes with one with a hole in the middle that the L-shaped bar goes in.

So here is an example of a screen done by IM Windscreen
