Back to working on the EFI project.

I kept having problems with the original 12Volt water pump and eventually it burnt out. So I found this little beauty lying around the workshop and plumbed it in for a temporary fix. The unkind suggested I put a skate board under it and ride the outfit in the side car class. The up side with the 12V pump being temperamental was that I found the engine boils up nicely without any damage, did it quite a few times.

28rwhp @ 12k rpm, not bad for a un ported MC21 Honda NSR cylinder on a Suzuki GP100 bottom end with a de stroked crank (48mm stroke for 110cc), and a Kawasaki KE175 rotary valve which opens 135 deg BTDC and closes 65 deg ATDC, mild as.

A reliable water cooled all day, never fade 28hp should be fun.

great perseverance TZ ... " HE WHO DARES,,,,, WINS"......

You may need an older (heaver) rider at the GP for that bike. I know a guy on the come back trail.

Thanks for the suggestions. I now have a couple of these coming, not sure how good they are but will give them a try. Big issue is current draw, I am not sure what it is for these, but hopefully small, as I have limited current reserves from the engines alternator, 2-3 amps is all there is to spare.

do you happen to know the weight of one of these buggers ? adegnes says they pump about 20l/m so how would that compare to the mechanical oem pump driven from the crank on the yami twin ? was thinking about a small spal fan (1.5lb= 652g) and perhaps a small electric water pump as well (assuming it would be a advantage over the mechanical pump). now I just have to some how convert my generator to DC and figure out how to wire in the fan and pump (maybe). electrical stuff isn't my specialty as you can see .

is that the same one as this bosch ? says its 1 kg and 20 l/m http://www.frozenboost.com/liquid-ai...02-p-1001.html

I thought it was but looking at the Ebay add again it looks like my enthusiasm for saving a dollar has lead me down the garden path and I have purchased a (Chinese ?) knock off. Time will tell if its any more reliable than the last lot.

From memory, given an adequate radiator, I think the rule of thumb is a flow rate of 1L/min per hp is required to maintain an engine temperature of 40 deg C. So I fear that at 20L/min ( with no head) the Bosch and copies are going to be a little marginal for that, and I may have to settle for 50-60 deg.

found this test of a few small pumps including the bosch. problem with some other pumps is I think they require higher than 3a and they can be well over 200usd

while im thinking of it, anybody tried something like this ? maybe its stupid idea but could you hook one end of this cooler to the carb and put a airfilter on the other end. then use a small pump and heat exchanger. http://www.frozenboost.com/air_water...ers-p-226.html

Would it be easier and possibly less expensive in the long run to buy a Davies Craig pump and possibly the controller too?

I don't thinck it will do the airflow any good

Thanks, yes that Bosch pump does not look so bad. Its max rated flow (20 l/min) is at 6 psi. At a guess I would say the head pressure of my system would be less. Maybe 2 psi and at that pressure the flow rate is near 30 l/min and current draw is < 3A.

There has been lots of good information posted about suitable pumps, thanks.

Pewee that is a heat exchanger based on an marine oil cooler.
They can be used as a water to air intercooler their airflow restiction is not too bad but the water temp and intake temp used for a NA engine means it is irelevent.

Or see if you can find a wax with a suitably low phase change and throw the radiator and pump away.

A quick look don't look promising, though... http://www.irmwax.com/products/Phasechange_wax.aspx

Edit: or fill the wee cooler with brine, freeze it and fit it just before race?

...and while it's cooling the engine it'd be heating the intake charge.

yes I know its a water/air intercooler for a small car I suppose. wasn't sure if it could be connected directly to the carb but then you would need a pump, water, and another radiator. rather heavy system . what about a small ice box plumbed into it ? then you could have cold air but not feasible on a small bike I guess
