Title: engine bay temps
Post by: Tintin on October 08, 2004, 10:12:49 PM
I was fiddling around in the engine bay the other day and I had an idea , but I\'m unsure if it will actually have any benefit

If I removed the cover thats on the underside of the bonnet , removed the engine bay undertray and vented it to direct airflow into the engine bay would this help lower the engine bay temps :confused:

The way I see it removing the bonnet cover will allow heat to pass through the bonnet easier and obviously the more cool air coming into the engine bay the better , but will venting the undertray allow water enter the engine bay :confused:

Do not remove the under tray. This helps push air through the radiator. Thats assuming that the radiator is in the stock location.

no mate dont remove the undertray. i think i am right in saying that it is vital that a low pressure area is created in the engine bay with a high pressure area on the outside. removing this will upset the balance. ie air will not flow as well through the rad but bounce off it.
