Recommendation on 12V water pump for W2A intercooler

[PeeBee]

I am looking for feedback from those who have installed a reliable 12V water pump for use with their water to air intercooler. I have found a couple of pumps but looking for recommendations. I think I want a flow rate around the 25-30lpm mark at a guess. Here are a couple I have found. There are some cheapies out there but not interested.

bosch 0392022002 for sure
as u can see in the video there is still plenty flow/pressure after going through the whole system.

I have a Davis Craig 80L/min pump on my W2A kit

Thanks Guys. Bene, I think this flowrate is too high for the port size on the intercoolers I am looking at. The 20Lpm Bosch unit is probably on the lower side also, however the flowrate is specified against a pressure drop so perhaps this is a good fit.. The ports are 19mm or 25mm depending on which unit I go for.

Davies Craig. 80-120lpm pumps. Flow is king with w2a. I would be using the unit that is 25mm lines.

The last w2a I setup had 1" lines and a Davies Craig 120lpm pump running flat out all the time. Although the pump actually tested closer to 100lpm. This was run through a 1200hp w2a core.

You can afford to oversize things on our diesels due to always being on boost and I would going the biggest unit practical since you are using a supercharger.

OK, another great justification, thanks beneboy, nissannewby, I will go this way. Right now its looking like a Plazaman w2a - custom unit - same config as they make for the TD42 turbo set-up, then running the water thru a FI interchiller unit so the inlet air will be frosty cold pre the blower. Waiting on comment from FI re the need or not to add a reservoir of some kind to the chilled water circuit - or just simply run whatever volume is achieved via the storage volume in the hoses.

Ended up going a bit bigger, based on the Davis Craig selection table. I can then connect this to a return chamber for full flood feed of the pump. Purchased off ebay at half the price direct from Davis Craig. I am sure I wont get the flow rate, absolutely guaranteed, but it will give me some margin to play with.
