Thomas,
No doubt they both have tight internal clearances, but
Eatons seem to be more resiliant when it comes to case flex than Whipple style
chargers. From the Eatons (M45 and M62) that I have held, I would guess the
weight to be in the 25lbs range plus bracketing, I have
not ever picked up a Whipple, nor would it be a direct comparison
since the smallest whipple does 1.2L/rev displacement, where as the M62 does
1.0L/rev. All in all you would probably be a little heavier than a
turbocharger setup due to the added brackets... plus you would want mufflers
which you do not have to have with turbocharged engines. Now on the other
hand... if you want to talk about noise... an Eaton will scream like a banshee
when you get the engine up to speed, a Whipple is a little more tame in its
banshee qualities.

Jonathan,
I never had either charger in my hands, but the system
seems to be about the same.
Eaton having bigger rotors, but it also must keep
tolerances very accurately or you get the same "failure mode" you wanted to
avoid.
Do you have any idea about weights between these
two?
