Firstly, I think if you ceramic coat the car, Mother Nature or a light hosing will handle any dirt. And can’t you also ceramic coat the plastic that surrounds the engine?? So it stays black and doesn’t get water spots? And don’t people dry their cars after a wash??? Apparently some even use a leaf blower. Lol. Hey whatever it takes man. I think it’s a darn small price to pay to showcase that beautiful engine. But hey, that’s just me.
Have zero idea how many hours my 32-year-old Ferrari 328 has in the rain..... but it's a LOT - louvers let in water.... 'tis a fact.... Drive it, enjoy it....
To quote myself,"No one on his death bed ever said I wish I'd driven the Corvette less."
Were that true, then how did the C7 get through the water test without it's foot well/s getting filled with water, as one member's new C7 did when driving in the rain, (or was it a car wash.....) as reported on forum? Several C7s made it through assembly without firewall putty applied by robot.
It's true. It's a fairly short test, so it is certainly possible that heavy rain could cause significant water leak compared to the water test at the factory. Every car produced at Bowling Green Assembly Plant goes thru the water test before it goes out to the shipping lot.
Here's a description of the Assembly Line from CorvetteBlogger:
In a nutshell, the frame with cockpit assembly moves through Trim, then on to Chassis I where the marriage of the frame and chassis takes place. The Engine Dress line feeds into the Chassis Subassembly where the chassis is assembled and then mated with the frame as it passes by. Chassis II is next, followed by Skillet I and Skillet II where the body panels are installed. The Corvette then moves through Chassis III where wheels are installed and fluid reservoirs are filled. Wheels touch down for the first time in the Final Line before it is started and driven off the line. From here, the new Corvette goes through Alignment, DVT (Dynamic Vehicle Test), a Water Intrusion Test, and final Quality Control Inspection.
Here's a video of a C7 going thru the water intrusion test:
With my 2000 psi pressure washer, I can shoot water through the side vent on the right side of the car and it’ll shoot out the side vent on the left side. Pretty cool huh.
My only point is there has to be a SOLUTION to the water getting all over the TOP on the engine- say a piece of ABS plastic was mounted
1 1/2 inches lower than vent sloping on a 45 degree angle away from the motor- this would allow for air to escape and DIVERT water away
from the engine- Or as on the Lambo have 3 vents in a row to let heat escape in a row on each side of the rear window- thanks

and the point that's being communicated back to you is that it doesn't matter and stop worrying about it. There is no solution needed for a non-existent problem.

Simple solution...don't buy one, or get the HTC if this is something that concerns you so greatly. My 72 Super Beetle engine would get soaked any time it rained on it or if I washed it. Just driving in the rain in general soaks most car's engines due to the mist being created by cars and trucks in from of you. The few times I ran my C7 through a touchless wash, I would have to dry the engine and engine bay after wards, its just a part of car ownership and really just seems overly nitpicky. I personally don't care about water intrusion in the engine bay because it gives me another excuse to pop the hood and clean it up, I also use this time to inspect the engine for anything worn or degrading. My sports cars have all been through car washes, and they all ended up with water in places you don't think about until you open the hood. God forbid you run your car through a car wash that has an underbody cleaning option...

People are concerned about reduced air flow as a result from putting screens with 70 - 80% porosity to protect their condensers. I can't imagine what a piece of solid plastic would do to restrict airflow and increase temps in the engine bay.
Most mid engine cars have vents to let the heat out. However, most of them are also exotic, which means it's not a daily driver for most people. They have other cars they can drive in the rain. Like others have said, if you are that worried about water getting in and/or the engine looking dirty, get a HTC.
