Water to Air Intercooler doing its job
hey guys
I have had a load of problems getting my Water to air intercooler running correctly, I went through 2 Davies Craig ancillary water pumps. these are
the worst parts I have ever used, no flow and becomes off balance after running for a couple of minutes with inadequate water supply. with this pump
my intake temp climbed to 80 degrees at about 13 lb, since re researching water pumps I learnt that most new luxury cars are using a similar pump to
recirculate hot water to their heater cores.
I purchased 2 x Hella water pumps from a 7 series BMW pumps for $150 from a BMW wreckers, straight away it flowed at least double the Davies Craig
units and soon after installing the system had bleed all the air pockets out and my temps are now down to a max of 45 and a low of around 25 degrees.
Time for more BOOST!

Hi
I used a Grocco agricultural pump on my 1302, they're used for hosing down deck on fishing boats and feeding live bait tanks. I later found that MRT
used them on Liberty upgrades.
I had heaps of trouble getting it to prime. What I ended up doing was fitting a garden hose connector into t piece before the pump and pressurise the
line until the pump ran by itself.
