Electric chargecooler pump installations


Recommended Posts

Aye. I've put the order in to a friend who has an engineering firm (currently on lockdown due to CV19 so twiddling his thumbs) for a blanking plug. I refuse to pay £40 plus postage for one when a bottle of red will suffice ;) . Ordered a Bosch 0392022002 pump which is the one used on the supercharged cobra so should be more than adequate. Need a few feet of hose to make good the circuit and Roberts your Dads brother!

Hard to imagine that thing was actually turning.

I reckon your whole charge cooler system could do with a flush/clean out. The charge cooler and especially the rads may well be in the same state.

Both correct. The insert was turning free and the whole system was gently flushed today. The vanes inside the charge cooler itself were very clean so I can only assume the crud in the pump was a result of stagnation and heat transference at that point. All required items now ordered and en route. Hopefully the whole system will be installed, primed and functioning in no time.

Bosch 002 pump is pretty weak (low pressure pump). If you necessarily want to stick w/Bosch brand, then use 010 pump. Price is not prohibitivePumpCharacteristics130421-page-2.jpg.861a336a9997cc74343e3260fa6f19a3.jpg

I need a new electric chargecooler pump, does anybody sell a kit including the pump and blanking plug? I thought PNM did but can't find it on their website. I need some piping for it too.

A new chargecooler twin header tank would be a good idea too.

Alan,

Yes they do. I bought mine there, incl. plug and everything. It is very far from all ther Lotus parts that show up on their webpage, which is slowly expanding.

So, if need be, just give them a call and have a kit.

I am still using my kit many years alter and it works perfectly.

Kind regards,

Jacques

Cheers guys, I'll give PNM a call in the morning. I'll ask if they do the twin header tank too, SJ's version is £195 ex vat.

Hi alan,

Oh yes, they do that as well. I installed that on my car years ago, and it's fine.

Contrary to the rusting original item, which will leak and send rust into the cooling system - great...

Kind regards,

Jacques

Unless the curve from the original engine-driven pump is plotted on the chart, there’s no meaningful comparison to be made whatsoever.

Here is a Davies Craig EBP-40 which I'm using for years.15444292_Coolingpumpcharacteristics.JPG.1562bc22b69fb6f2990bfc85a97b236f.JPG

I used the commonly available Bosch 0392 022 010 pump (more flow than the ~002 pump) and 3/4" lines for my install. Seems to work fine with my low resistance heat exchanger. I mounted it inboard of the gas tank and don't hear it running at all. 

I always was curious what the resistance to the pump flow was, I would guess that it should operate at a low pressure across the pump if the lines and heat exchanger are big enough.  Time averaged results versus the engine driven pump should be better just on account of the electric pump running at full speed all the time.
