I have extra radiator from my datsun from when I was troubleshooting the Cooling system. I'm going to sell the rad for about $250, then take $50 of those dollars to buy a small cheap civic rad. The rest will help pay off some bill.

The reason I'm going to buy a huge rad is because

A) its much wider and thicker than any other rad out there for extremely cheap.

B) A widely know fact that bigger fans are quieter and can puch much more air.

Nothing is wrong with 1/2" ID tubing on 1/2" barbs... It won't be as snug as the 7/16" ID tubing on the barb initially, but that's what clamps are for

7/16" is fine fwiw. You lose a little bit of flow....

I'm thinking of using the 7/16, because I think pressure is my biggest problem and the 7/16 will have a tighter seal than the 1/2

Two words "Galvanic Corrosion"
This is what happens when dissimilar metals are placed in the same cooling loop.

this is what you will get if you use a Civic radiator (Aluminum) and a Copper water block
You will need to ether get a rad. that is made out of brass and Copper or make your block out of Aluminum

7/16 tubing will have a higher resistance to flow then 1/2 tubing thus raising your system pressure, remember pressure is merely a function of resistance to flow

Very good point. This is a major issue you will encounter. Although you should, to make sure, make your block out of aluminum or get a copper rad, I think you can buy some additives that prevent galvanic corrosion. <-I'm not sure though...

A pump that puts out 1500 g/h will dump a lot of heat, possibly cause pressure leaks, and I seriously doubt it will have fittings that fit it, or would work on 12V, ie need external power supply.

As an aside, the D5 has 10 feet of head with translates into 5 PSI. The mcp 35x has 14.7 feet of head which converts to 6 PSI (assuming a few standards)

The PSI listed for D5/mcp 355 pumps is not the pump output PSI, it is the max tolerance of the housing to pressure. For example the D5 brass pump is listed as 150 PSI (meaning it can withstand 150 PSI prior to leaking/bursting). The D5 noryl plastic is listed as 21 PSI, some are listed as 50 PSI. Nothing to do with performance, just strength of material/construction. Mcp 35x rated at 22, means plastic housing will withstand up to 22 PSI without leaking/bursting, etc.

Problem with pumping power, is at some point you will reach diminishing returns in performance, and simply be overshadowed by the extra heat dump. And 1500 gph, be prepared to come home to a mess when something leaks from the pressure that pump is likely to generate. Even Iwaki RD-30 only puts out 1/5 of that flow.

Car batteries are around 12-12.6V. That's not to say there couldn't be a step up/down circuit that normally feeds the pump, but 12V equipment isn't that hard to find on a car.

opt33 is correct, that is the maximum continuous pressure rating of the pump, not the output pressure.

For example, if we look at the Black Ice GTX 480 rad it has a maximum continuous pressure rating of 24.7psi (look at the "features" tab). If your D5 really was putting out 50psi then you would blow your rads, blocks and tubing apart the second you powered up.

Incidentally I believe this is why some people think that the D5 is a better pump than the DDC for high restriction systems, due to it's "high pressure rating".

As to the OP's question:

Yes, you can have too powerful a pump. If the pressure gets too high (see above) then you can physically damage your components. This is unlikely though, unless you really do have an uber pump. Do you have a maximum pressure rating for it?

Also, as opt33 also pointed out (I like this guy!), at some point you will be dumping more heat from the pump than you will gain in performance. Where exactly this point lies depends on the pump and the loop, it would be difficult to work out without testing.

Be aware that the flow and pressure ratings of a pump only indicate two points on it's PQ curve; maximum and zero restriction. How the pump will actually perform on your loop depends on the PQ curve and your loop.

Too much heat dump..anything over around 50Watts will cause more heat harm than flow good..not to mention most watercooling gear isn't designed to hand much more than about 20psi. I've seen a damaged GTX rad from household water pressure which is in the 50psi range.

I've also exploded tygon tubing using using household water pressure myself..face full of water..
