Electric or Mechanical Water pump for street/strip

[73dart360]

I purchased a 67 coronet 500 with engine out of car ,it has an electric water pump already attached ,I do want to turn the car more streetable when i can afford it ,it has 12-1 compression,electric fan which i think needs a clutch fan with a shroud but while the engine is out am i better off with an electric water pump or a mechanical ,its easy to change now if so.

I'd say with more street driving than track run the stock non A/C pump or some max cool setup. The benefit of an electric pump is really for track use where you can circulate water with the engine off to cool it down in between runs. Also the electric pump will put more electrical load on the system, and if you run it on the street, you may need to upgrade your alternator. Nothing is free!

meep is correct,as usual.switch to a mechanical pump,even if you run the electric fan set up.you will be much happier in the end.biggest thing is that you wont know if the electric motor fails untill it is way too late.when you are racing,you pay much closer attention to the guages,and will catch an over heat before it dose any damage.

I ran a stock type pump but ran it with a Moroso electric motor drive kit. http://www.streetsideauto.com/c/coo...mp drive kit&gclid=CODzufL8gbcCFQTd4AodbmIAMA

I run a stock belt driven waterpump on my 63's 440/493. I just added an electric fan on the outside of the rad as a pusher for when stuck in traffic in 95 plus degree days as it helps keep it below 195 when stuck in traffic. Ron

Here's some food for thought........If an electrical ran system fails (be it the wiring, relays, pump, fans), typically your dead in the water. A mechanical pump driven system has less stuff to go wrong and if it fails, usually you will have a heads up the end is near by water coming from the weep hole. On that end, you may have some time to get it home or get it fixed before you're stuck on the side of the road with the hood popped up. It's also cheaper! A lot cheaper!

A good mechanical pump like the Mildon HI-VOL w/ anti-cavitation plate, 180* Thermostat, clutch with vicious fan, shroud and decent radiator will have no issue cooling that car. Looking at a lot of cooling systems folks are putting on their cars these days is kinda of comparable to what some are doing with fuel systems. They toss a ton of money at fancy pumps, electrics and bling all while creating an over-engineered complex system that has lost reliability with all of it's additional components. In the mean time, the electrical system is over taxed and the basic dynamics of how the system actually works and why is lost, thus leading to issues. Do your homework...keep it simple and stick to the basic principles of the system you're trying to build. It will be cheaper, probably work better and be more reliable. Good luck.

You are correct!

This is another way to look at what Will is sayin' .. go with the K.I.S.S. principal
