I recently had an opportunity to get the car up to 150mph, but whilst doing so, the rear wiper flipped up and remained up, almost snapping off the arm. Anyone else come across this little feature? Anything I can do to make the spring stronger? Or should I be looking at some other fix?

Will you be doing 150mph alot from now on then.

Maybe the spring has become weak, or its a side effect of the WRC wing and the aerodynamic change at speed causing the wiper to lift.

I thought it could have been the wing however, the air has passed the wiper before being affected by the wing....I am ...of course...not an aerodynamist.

Has been fine upto 130mph previously....but then again this is Q driving...not another thing you've broken?:(

Wasn't there a modified rear wiper arm for the Octy MK I due to it coming up or snapping off at speed?

Only where permitted of course

I certainly didn't have it on my previous octy, so the wrc wing could have some effect on it

I'm merely testing the claimed performance... someone has to do it

Not sure, but it does ring a bell... I'd do some more searching

Probably prevent it from happening, if you were to slow down.

The next time you're planning this - About 10" of duck tape should keep it down.

Dont worry Aaron, as it only happens at 150mph, so it will never affect your Honda.....................:P :P :P

Now I only need to find out my VIN number...

It's on the windscreen.

Perhaps a swap to the aero wiper will sort it.

believe this was a recall, if you need the range of affected VINs, PM me

I'd suspect a weak spring in the first instance. OTOH it's also possible that the arm is in a low pressure pocket due to the way most production car aero works (it doesn't actually produce downforce, just redirects air to reduce lift.

I'm not an aerodynamicist, but work with several.

What's that all about then?

Major coachbuilding project?

A limousine body has a full height partition between the front seats and the rest.

the air may have already passed the wiper once but the wing may swirl it around and lift the wiper from the back if you see what i mean.

aerodynamics is a funny old thing, on my brothers car if you travelling at around 40mph(i think) and water drips off the tail gate you can see it getting thrown back upwards by the aerodynamics

:iagree: - well, I'm not certain about the wing creating a rotor from behind it to back in front of it, but it certainly could create a standing rotor in front of it, in the area where the wiper blade parks. If you then get a yaw component hitting the arm that could create a localised lift force on the arm, although there's still a net reduction in lift on the tailgate.
