Default Recomanded Air inlet with Webers

Hello

A friend has a ERA with 48 Weber Carburattors.

When accelerating the Engine is not Running nice.

I guess that is because the Intakes are too near to the scoop.
And no fresh Air Flow is arround the Carburattors.

It is getting better with More speed. (Better airflow)

Is there a good Solution for the intakte Air Flow with 48 Weber?

Best Regards and Sorry for my bad English ….

Lemmy,

Ihr Problem ist höchstwahrscheinlich nicht das Design der Motorhaube. Denken Sie daran, dass Shelby diese Autos mit diesen Webern und dieser Schaufel gefahren ist. Ihr Problem besteht mit ziemlicher Sicherheit darin, die Weber für die von Ihnen verwendete Motorkonfiguration abzustimmen.

The Carburattors are been adjuted on a Dyno,
Thats what the last owner did.

Puts out 400 HP on a 427ci, with 48 Webers
I guess with no hood tested.

Next Summer i will Check with some Airflow modifications.

Best Regards
Andy

Der Luftstrom ist nicht das Problem. Der Spritfluss ist das Problem. Weber sind außerordentlich einstellbar und auch außerordentlich schwer einzustellen.

Die Abstimmung auf maximale Leistung ist nicht so schwierig. Das Tuning für eine gute Drehmomentabgabe und gute Fahrweise bei Teillast ohne Renngeschwindigkeit ist ziemlich schwierig. Während es hilfreich ist, Zugang zu einem Prüfstand zu haben, geht nichts über einen erfahrenen Weber-Tuner mit all den vielen Düsen und Entlüftungen, die für ein gutes Fahrverhalten unerlässlich sind.
