Here is the info on my project. At this point I have molds made to replicate the stock hood. Next version will be with venting near the radiator, like the Daytona Coupe. If anybody wants, loan me a LAT hood and I’ll gladly make a copy/mold of it for later use. Labor and materials to be discussed when needed.
Actually the shelby BP race tiger experimented with a bonnet vent behind the radiator like the gt40/ daytona early in its race development.
I’m working on this design to add cooling at low speeds and in traffic. My car runs just fine when moving but a bit warm in traffic. Letting the air out before it has to pass the headers and exit might be a better idea. If not, there are many other options.
I think the horn hole blocking plates are probably a more effective solution for stop start and low speed over heating issues
I’ve done that already. I figure every bit helps. Now to fit the prototype hood and see where the vent will go.
Here is the latest photo of the vented hood project. Measured to vent just behind the radiator.
Nice thing about fiberglass, it is trimmable and then re-shaped if needed. It should be no issue.
I have never experienced this problem with my LAT hood. The hood "exhausts" are at the rear corners. The intake for the vents are centered just in front of the windshield. I guess if the wind is blowing just right and the car is sitting still, hot air coming from the hood outlets could get to the intake for the vents. But I do not know what would cause the hot air to be sucked into the vents, only into the heater/defroster blower. At speed, the air in front of the windshield is moving a lot slower than the air at the corners of the hood. Slower air is higher in pressure than faster air. (That is how an airplane wing's shape provides lift to the wings.). So when the car is moving, I cannot fathom how air coming out of the hood outlets would be pulled towards the middle of the windshield's base. Maybe I am missing something, though.
