There all pretty the the same unless you get an electric w/p. Meziere has a heavy duty version but reqiores some cutting of the passenger side fan shroud.

There is no high-performance, cam-driven water pump per say. As mentioned, the only way to add some hp is to go with the electric version, in which case Meziere or CSR make one. Check out the supporting vendors, several sell them as do Summit and Jegs.

Ok, excellent I checked them both out. I noticed someone stated that i'd have to do some work to the fan shroud in order for the Meziere pump to fit. In your opinion which one is the better of the two? Also what would I hook the pump up to?

I don't know about the CSR, but I did have to trim the fan shroud a little to fit my Meziere. It wasn't too difficult with a dremel and cutoff wheel, it probably took about 5 minutes to remove some of the plastic ribs that interfere.
As far as wiring, I used the power circuit from the AIR pump (which i had removed), including the fuse and relay, with the relay triggered by the fuel pump circuit (so that it's always running when the engine is).

Be aware electrics free up power by moving A LOT LESS water.

Do not know what your definition of "high performance" is so this is something you should be aware of.

The stock pump is pretty good moves a lot of water with realatively little cavitation at least compared to older designs.

Its up to you, if you want to add a little extra power and don't mind going through the additional steps in installing an electric pump, then it may be for you. Otherwise, just go with another mechanical driven unit and bolt it right up.

I thought electric pumps freed up power by being, well, electric.

CSR requires grinding of the aluminum housing. Nothing big but an additional step. However, no shroud mods.

I am very happy with my EWP.

I don't know about the whole "electrics move less water" bit but for what its worth I have installed three different electrics on three different motors and none of the three ever overheated due to "less movement of water" if anything they move more water when your sitting still which is when you would want it to be moving. The electrics move the same amount of water weather your sitting still or doing 75 down the freeway. The electrics free up hp by not putting resistance on the engine. as to which electric you go with depends on your pocketbook or you desire to cut platic or aluminum. Meziere has two models for the LT1 the regular model only requires a few cuts on the fan shroud. the hd model requires more removal of the shroud than most people feel comfortable removing. I have done both and unless your going to be running nitrous then go with the standard model.
Good luck

My engine stays nice and cool w/ my electric WP.. as cool if not cooler than my stock WP setup. It can idle forever without getting warm.

I haven't heard of the "alot less water" thing either...

I don't know where the info came from but I've read several times on here that the stock pump flows 25 gals/min at 6000 rpms. The electrics flow about 35-40 gals/min at all times. I recently added a CSR pump and am very happy with it so far. I ordered a temp sensor from longacres and am going to wire up a warning buzzer to let me know when the car gets above 230.
