I have been running Meziere eletric water pump on my '03 Mach 1 for about a year now, with absolutely no issues. Considering that this mod alone gave me about 3-5 hp on that car, I am thinking about doing the same mod on the '05. I assume it would be the same pump for the 4.6, but are there any other issues I might run into on the newer car?

 

MMR has one for $369. I however have no basis for price, so maybe someone can tell us if this is worth it.

How much extra power do you normally get from underdrive pullies? Might be a cheaper alternative...seems like a bad idea to use both at the same time.
