We are planning to use an electric water pump on an F4i motor, we were wonedering if anyone out there has used one on that motor. If so, what was the flow rate that was needed to have the engine run reliably?

The ideal water flow rate will be determined by three things. Heat load of the engine, the radiator used, and the fan flow rate. Only when you have all three of those things can you determine the water flow rate, or if you have the water flow rate and of those things you can determine what the other needs to be to perform ideally.

The Davies Craig Pumps work great, most of the Australian Teams run them.
Choose either the EBP or EWP depending on your ccoling requirements Regards, Scott Wordley http://www-personal.monash.edu.au/~fsae |

Thanks BeaverGuy and Scott for your inputs. This will help a lot.
Scott, I was wondering where one might be able to get the pumps which you mentioned and how much do they cost? Once again, thanks for the help. Sami Ahmed UMD Racing Team FSAE "Drive it like you stole it." |

I use two EBP's in series to overcome problems in pump startup (EBP's don't like having to suck too much) and as a backup in case one fails.

Reduce parasitic losses in engine.
You can also have control over when the pump is on or off. No need for thermostats. +1 for Davies Craig, just don't drop them Fred

A good idea would be to plot flow rate of your current pump, figure out what sort of heat transfer it achieves at those rates with your radiator setup, and shoot for the minimum flow rate that dissipates the correct amount of heat with your electric.
