How much reliable hp & tq gains are seen with the addition of this water pump. I've been told from 5-10 hp.

I currently have a 160 degree thermostat, so water temp is not an issue...
But I'm looking to free up some power without going to a reduced pulley on the alternator.

I gained zero hp and torque when I switched the Meziere for the stock water pump on the same day.

Save your money for something else.

I also gained 0rwhp from mine too. Wish I had that $$$ back to spend on something else.

ok.. No gains. What dirreances did you see else were, if any.

I made a pump replacement casting so have no pump mounted on the engine at all. It has water passages enlarged to the size of the gasket dimensions and is much smoother on the bends. You could also open up the block to suit, use any stat you want and run an inline pump mounted on the hose. It doesn't have a bracket for the idler as it wasn't done for stock cars but I did it to increase coolant flow with flexibility for retrofit cars. I prefer the idea of an inline pump with temp control.

What do you mean by any other differences? The Meziere keeps the car very cool for sure.

And the Meziere does look alot better than the stock waterpump, especially a chrome one.

At the track the Meziere would be good, but for street use forget about it.
