Guten Morgen,
ich spiele auch mit dem Gedanker einer anderen Haube. Mopar oder eben AEV. Zu Mopar habe ich nichts gefunden aber AEV steht auf deren US Seite Rede und Antwort und schreiben dort folgendes:
Does the Heat Reduction Hood really reduce temperatures?
Absolutely! Of course we designed the hood to be aesthetically pleasing, but we also put a lot of fluid analysis into the location of the vents. There is a low-pressure area created at the front edge of the hood when the vehicle is in motion, and we placed the central vent of the hood in a position to take advantage of this. Since air likes to move from high pressure to low pressure areas, the placement of the center vent causes cooler outside air to be sucked through the radiator and up through the hood to fill in the low-pressure area.
Chrysler has tested our hood in both the wind tunnel and on one of their most severe hot weather tests, the Davis Dam Grade outside of Laughlin NV. This is about a 15-mile grade with very high engine RPMs, high ambient temperatures, and high loads. Here are some excerpts from Chrysler’s “hot trip” report: “3.8L engine coolant temps ran approximately 5 degrees less with the AEV Hood. AEV hood was then put on a diesel (2.8L) JK and very positive results were experienced. The vehicle ran 5 – 7 mph faster up the grade with a trailer.”
When Chrysler subjected the hood to a different test in the wind tunnel, the results were similar “DAVIS and USCTY were run to evaluate AEV hood. AEV hood helped coolant temp (2.5 degF), Trans temp (4 degF) and Air box inlet Air temp (8 degF). It also helped some thermal protection components during Davis55.”
Besides engine performance, the AEV Hood can help significantly with the heat buildup in the under hood electronics, such as the TIPM (Total Integrated Power Module) which will shut the entire vehicle down if it gets too hot. Don’t be fooled by other hoods that are designed solely for aesthetics, they won’t help cool your vehicle (many have the vents placed in useless areas from a thermal dynamics perspective).
Was das Wasser angeht so mache ich mir da keine sorgen, wenn ich da sehe wie manche Motoren nach einer Geländefahrt so aussehen!!!! Da ist wasser von oben quasi lächerlich.
