Default Re: Lighter wheels = any E.T reduction?

Gentlemen--- Car Craft Magazine had an article a while back whereby they tested different transmissions and the Horsepower required to turn a transmission. I do not know if these are totally stock trans or were modified in any way, I also do not know if theTorque Convertor was used in these tests. These are THEIR results:

Powerglide---18 HP
Turbo 350-----36 HP
Turbo 400-----44 HP
C-6--------------55-60 HP
C-4--------------28 HP
A904------------25 HP
727--------------45 HP
