Re: Any thoughts
Man, I know nothing but do not believe for one second that the Germans did not think of that. You don't know what happens to the air under the car and there is a chance that this might just suck in hot air. Could work if you could connect a pipe to this leading to a air intake in front...all sealed off course.

Re: Any thoughts
AFAIK - The idea is to get rid of the hot air in the engine bay and sucking in the cool air from the vents.
Thats why all the tins and seals are in place.
Is your engine running hot ? If it is, get to the root.

Re: Any thoughts
that'll suck in hot air if the car is moving slowly.
There are people who have done something similar, but they have run a duct (flexible tumbledryer style hose) to the front side of the gearbox. But again, in slow moving traffic on a hot day, you are sucking up air that is pre-heated by the black tar

Re: Any thoughts
Agree,....sealing off engine compartment is 1st prize,.......then if you are bored or spare cash lying all over your work table,...then devise a plan to get air into the engine compartment ! It will help. I believe today's temps are definately higher than 40 years ago!.....or add ann extra oil cooler !?.....now this idea can get a reaction !!

Re: Any thoughts
Ive often wondered why Volkswagen made the cooling so complicated on a beetle, there must be a reason.
Here is one of my solutions

If you need an extra oil cooler on a stock engine, then you have other problems.
I think the VW cooling setup is one of the simplest cooling systems around. Nothing complicated about it when you look into it properly, including the position of all items, and also take into account the oil cooling system.John Alves wrote: ↑Tue Feb 18, 2020 11:53 am Ive often wondered why Volkswagen made the cooling so complicated on a beetle, there must be a reason.

Also, your pictures, that duct leading to the vents... that is exactly how the system works, just, it doesnt need a duct.
Engine bay is sealed, fan and carb suck air, creating a low pressure zone, air from high pressure zone around rear window flows into engine bay. Cold air pushed over engine, expelled out the bottom and if this air does make its way to the rear window area again, it is so diluted, its added temp makes no difference.

Re: Any thoughts
I just thought that my system would eliminate the need to seal the engine compartment, however the carb would probably also need to be connected to
the ducting system, I don't know enough so will leave it to the experts.

Re: Any thoughts
The T3 works like that but the ducting does restrict flow as air will not move effortless
against a wall of the ducting.
Thats why they have gone back to the sealed engine bay in the T4 engines.
