Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Spray on Inside of Windscreen

Short of taking the car to the full size wind tunnels at Williams or Red Bull Racing I'm not going to get any real evidence and even if I did what can be done?

My considered view is that the air exiting from under the car is the cause of a low pressure area towards the back of the car which is made worse by a low pressure area behind the screen. So air rushes in from the sides, including spray from the rear wheels.

The answers are not going to be simple: changing the airflow under the car isn't done easly and can have unwanted side effects. As someone said, altering the screen rake isn't easy either. It would be very interesting to hear from the owner of a Speedster to know if the lack of screen changes the airflow in the cockpit.

I think answer is that there is no answer!
Reminds me of the story about a clever marketing person who analysed a gap in the market to death, only to discover that the reason there was a gap in the market was that there were no customers in that sector, so no market.
