well 5 year lifetime doesnt sound very loud
??? Care to explain what the hell that sentence means?
i might look for a more efficiant pump
So I'm assuming you have a great knowledge of pumps then? If so...why don't you give him suggestions instead of simply saying "get a more efficient pump"...it's inefficient compared to what exactly?
1/2" OD (outer diameter) Nozzles is what 1/2" ID (inner diameter) tubing goes on.
the D5 pump is quieter and apparently has variable speed controll...don't much care for the variable speed, but the quieter is better. D4 = MC650 BTW, so I'm assuming the D5 is probably the MCP655
Those are basically the best pumps you can get in that price range..your other option would be an AquaXtreme 50z in which it's like AMD vs Intel...some people say 50z is better, some say the D4/D5 is better.
The next step up would be something like an iwaki Z pump which run for about $175 and are pretty big but they pump crazy amounts of water.
heatercores do give you better performance than a normal radiator....heatercore is water passing through small fins whereas radiator is copper tubing with (generally aluminum) fins attached to it.
heatercore may look uglier, but you could always paint it yourself.
I can see why you have a poly "T" in there for the danger den fillport so you can simply use a t-line, but why do you need a "y" splitter?
Other than that, everythings fine
Pretty much exactly what I have except I bought my own heatercore from an autoparts store and modded it...it's a bit different from yours...I think it's thicker than that particular one...but yeah, same block, same pump, fillport...I have the maze4 but I have the brass top.
