Go with the electric pump. On my ride the switch was worth .2 tenths pump/fan.

Its a tough call as to witch one to pick. If you have the aluminum housing Id consider either a Moroso or Meziere drop in. But I dont think they are nearly as efficient as the complete bolt on counterparts.

Summit has their own pumps now too but their listed price doesnt include the manifold housing.


As far as the pumps motors continuous duty, Meziere claims 2000 hours.

And as comparison Summit claims 10,000 hours.

Ive not seen nor recall any claims from Moroso on thier pumps life.

But my advice, go with a electric pump as I know your looking for extra hp. And any of the pumps listed above should be enough to cool your ride and then some. mike
