CBR 600 F4i Water Pump Corrosion

[Shawn Madro]

We have been fully redesigning our cooling system this year in order to remedy many issues we have experienced over the past few years. As part of the design we had to consider whether or not to go with a mechanical or electric water pump. We have decided to stick with the mechanical variety as it seems to be much more reliable.

one concern is the rust build up from the mechanical water pump's impeller. Has anyone come across a mechanical water pump with a non corrosive impeller for a Honda CBR600 F4i? We would like to either buy a new pump that mounts on the stock mounting points or buy an impeller that we can replace the rusty one.

I don't really think this is an issue, unless you have oxophobia. Hundreds and hundreds of cars run straight water. The blades do get a bit rusty, but it's rarely that damaging. OE's switched to plastic impellers in some cars, which always look nice until the vanes snap off in 15 years and you blow a radiator up on the freeway.

A little anti-corrosion additive (a miniscule amount, as per the rules) and you're not likely to damage an impeller within the FSAE cars service life.

Also, if you have a lathe, a mill, and a couple of rotary tables, why not make one?

E36 you say?

Or, save some weight and add some control with a Daveys Craig electric booster pump! Simple.

FYI, 99% sure this changed last year; can't add any watter wetter, etc anymore (@ least while at comp).

Using clean water helps - so distilled/filtered &gt;&gt; crap out of some old garden hose.

Mazda MX-6. Poor little car. It's since been bequeathed to my brother and has been repaired.
