they SUCK

anyone improved em? stronger motor? better arms? faster swipe? intimate setting (intermitant imean)?

anyone though about this sort of mod? i was going to try twin water sprays aswell but this may require a stronger water pump

also for you auto elecs (phunk ect.), is there an easy way to mod the current system to provide one or two high speed swipes and maybe even a sparay at the touch of a button rather than pulling the knob in and out, or is that a big job

firstly i say whhhhyyyyyy?

secondly yeah you can have 2 sprays just like a 1200 sedan without changing the pump
you can have a spray button just by putting a button
and you can have 1 high speed swipe on a button but 2 swipes needs a wiper control relay

when rallying you often get a splash of water/mud across the screen which just requires a quick swipe or two to remove but you dont want to have to muck around because you dont have time to take one kand off the wheel to do that sort of stuff, i know its being picky but its one of things that would be nice to have

when i say twin spray i mean two jets per squitter piece totaling four lots of water hitting the window for better quicker coverage (i doubt sedans have this do they?), im thinking a strong pump might be the go anyway cause the current spray is strongly affected by wind anyway, spraying totally diffrent places like straight over the roof or more towards the passanger at diffrent times but never in the right place!

its quite scary lossing vision on thin roads with shapr corners coming up and big trees waiting to tell you you made a mistake trust me

cool,

i doubt sedans have this either, it would work still but if you are not happy with the pressure just change the washer pump or bottle and pump for one with the desired pressure.

hello,
you must try a spray in the wiper like the mitsubishi canter, you put the spray in the arm of the wiper , in normal circulation it guves excelente results .

bye

change the water tank for better pressure as phunk said and maybe cut more holes and fit more tubing to possibly three sprays ( six holes, 3 nozzles) depending upon how u wan your car to look and whether its just built for rallying if it was me and i wanted what u want id make more nozzles on the bonnet... should be easy enough

You can insert a needle into the squirter nozzle and alter where they point...

Isn't the problem with most older cars and windscreen wipers the springs? That they loose springyness (Techinal word)?

Also, I have found that the silicon wiper blades work heaps better than any single, twin, multi, etc rubber ones that I have tried...

I was cruising on a freeway road in the rain at 120mph once (1200 sedan CA18DE non-turbo) and I found the wipers were almost useless, I had to slow down.
Using a "rain-ex" treatment on the glass can help to improve the visibility through a rain covered window, this is important between wiper sweeps.

If we estimate that a 1/4 cup of water hits your windscreen for every square meter you pass through. Assuming the surface area of a 1200 windcreen is 1.0 square meter, at 180kmh you pass through 750 cups of water / second. 1 cup = 236.5mls therefore 177.37 litres of water hits your windscreen every second at 180km/h.

This is why 1200 windscreen wipers aren't much good when you drive fast in the rain.

surely that cant be right????????????

im thinking swap the water bottle for twin nozzles and trying to find a replacement spring might work for now but im going to investigate putting in a diffrent motor for the arms for a bit quicker swing

Quote:A 1200 sedan? Surely you mean 120 kph (just kidding, I know your car is far more powerful than a stocker).

Isn't that what those wiper arms with the airfoil are for? High speed usage. The airfoil is supposed to keep the wiper arm against the windscreen. I never tried them myself (that is, not at high speed).

On the other hand, the 1200 wipers are inadequate at normal speeds in heavy rain. I would think other car's blades (or aftermarket) would fit on the splined posts. A longer blade might help. But I think the motor might need a little more juice.

Variable speed and intermittent is possible with a little add-on box, like JC Whitney sells. To do intermittent, you either need to use the manual method (turn it off and on every so often) or use an electronic circuit. Some older vehicles had mechanical intermittent IIRC, but this wouldn't be easy to make. I seem to recall a cam-based system on some older cars. (I used to rebuild and test wiper motors, but that was 20 years ago). It might be pretty easy to swap in a different OEM unit (say from some newer Nissan model).
