An eliminator is not a performance part, it is a performance reducing
part because the fan is always turning at full engine speed, but it does
eliminate a potential failure point (the fan clutch) so it makes your ride
more reliable for being in the middle of nowhere, but saps power from
the engine, about 5-7 HP on average as a guess.
If you want a little more gas mileage and power from your Samurai
(who doesn't) you should go with an electric fan setup instead.
