Electric Water Pump Options

[tim510]

I'm not sure what generation controller I've got on the mr2, but so far it's worked perfectly. It warms up quickly and keeps a constant temperature.

the newer one has the digital read out, mine as has pot adjuster on the top of it.

i just run the pump flat out.

Has anybody used one of the electric water pumps to experiment with reverse flow cooling?

I will be with the 4AFE I'm building.

Ive got a Moroso external water pump drive like the one shown in the pic, havent had a chance to test it out,

IMO the only real benifit to running a electric water pump is the fact you can still have the pump and thermo fans running after you have turned off the motor

VPW sell the one i pictured.

Ben, you run yours between the themo housing and the bottom tank dont you? But without a thermostat i guess. Any way of doing it with the thermostat still in there?

[Ben Wilson]

Yeah - Mine is in the bottom hose. If you use the controller having a thermostat shouldn't be a huge problem, it shouldn't start until the thermostat is open.

My new car runs one as do many of the turbo MX5 racecars around. They work well and the newer controller seems to work well too. It's a good idea to have a dash light so you can make sure it is running - no water pump kills a race motor real quick!
