Question about the Rain Tray

[rp930]

Tray out. Love the look. Can always reinstall.

How about a contest on who has the most cobra/shelbys instead?

HA! Even better! Lol

There is zero doubt that more heat escapes with the rain tray removed. There is zero doubt the hood lifts a lot less with the rain tray removed.

In my personal experience being caught in a heavy rain, and then leaving the car in said heavy rain, after stopping for several hours, only left me with minimal water on my air box cover & degas bottle. Same results washing the car.

Good enough for me.

Any idea around what speed the hood lift starts happening? That's an interesting aerodynamic observation....especially if it's below 80mph or so.

I can only speak of mine, but driving it home from purchasing it on the freeway the hood near the windshield was vibrating and bouncing up and down at 60-70 MPH. So much so that I pulled over to open the hood to see it something was loose. Got home took the tray out and went for another ride and the vibrations and shaking were gone.

I live in the SF Bay Area and never drive the car in the rain so not worried. I've washed my car a couple dozen times with garden hose and spray nozzle and no water gets in. Of course I'm careful spraying on the vents I usually just lightly spray that area and clean with a cloth. The rest of the hood I just spray around the vents.

Interesting, I have it in still, I took her up to 120 on a nice open no traffic stretch and I did not see any vibration or hood lifting.

Mine was shaking around 60-70 as well. Steady as a rock with the tray out.

The question answers itself....why is it removable? Why do you remove it at the track? Because it has performance improvements without it. (Heat removal and aerodynamic benefits)
My guess is that it is installed with the thought of sitting for extended periods of time out in the elements before purchase, and for the owner that doesn't know anything more than they have a cool, expensive car that gets driven to and from cars and coffee events.

It’s been raining all day and I drove to work so here’s a quick video of the effects of leaving the rain tray out on a Python hood vent.

Great post Evolvd thanks for sharing. I think your Engine is now toast though will "all that water" in the engine bay. lol

If you didn't open the hood what little water in there would have vaporized once the engine comes up to temp.

Nice post, good information, thanks.

I can add that I had even less water in my experience.

I think it’s funny people stress so much about this. The majority of the water intrusion was from the car sitting still in the parking lot and 90% of it was on the radiator support and intake tube…exactly where the rain tray dumps any water it collects.
