What are the advantages or disadvantages to go to an electric water pump instead of stock?
Makes you think it aint worth the 10hp. Picture coming back from the party and your waterpump goes bad. Might pop a head gasket or spin a bearing. What do you feel is better mechanical or electric reliability and hp speaking?It is on the chance that the one you have on the car goes lol
Well if it did go, electric or not, I would pull over to the side of the road and use my celly to have someone scoop me up.Makes you think it aint worth the 10hp.

Have had a "spare" EWP in the trunk for years...along with serp belt, qt oil, tools, etc. mainly because buying one at a "local" auto parts store won't happen. With that said I have never needed it in the 9 years I have had the EWP. If it ever went out I would have AAA get me home. If I was out of state or in a place where towing would be a bigger problem....swaping in the new one would only take minutes. I also have the "quick bleed" nipple on thermostat and a small tube to feed into colant tank so bleeding the cooling system is simple.I see most people who go Electric usually keep a spare pump in their trunk. Is it that much of an issue that you really need to?
Thanks. I have already installed a couple other items from Gary (headlight, battery harness). I will be picking up one of these also when I buy the EWP.Meziere 118 HD. many places to buy, Summit
If you can change a stock WP and have basic wiring skills...this is not a hard job
Really???They free up power by moving LESS water. If you use datamaster to watch water temps you will see higher temps at 75mph than at 30mph. Not too high but high enough to verify that it moves LESS water than stock mechanical.
I noticed that coolant temperature got slightly cooler at highway speeds with an electric waterpump even with steep gears. At full throttle it may be a different story. It's the rpms, not the mph, that affect the flow. The behavior you are describing can happen if the car does not have the lower air dam.They free up power by moving LESS water.

All electric water pumps flow significantly more than the stock mechanical water pump AT IDLE. (The Meziere 118HD flows more than all the other electrical choices.)They free up power by moving LESS water.

Though this is true, they started whining, and eventually squealing, before they failed, at least in my case.They are also more likely to suddenly completely stop than a mechanical.
The closest my wagon has ever been to a dragstrip, is Francis Lewis Boulevard, and I'll never dare do more than 48MpH on it for fear of being accused of drag racing there (too many cars have been impounded there on the accusation alone).IMO the ONLY reason to use one is for that last .1 at the dragstrip.
My car is garaged, slow, and it's no queen. I've been abusing it since 2003, for the past 95,000. (If you saw it, you'd wonder why it runs so much better than it looks.)96capriceMGR said:Since early 2000 the only cars I have owned have been 94-6 b-bodies, having put over 200k miles on my cars for daily driving and fun I know my way around the platform. Not one of those guys with a slow garage queen. Just this fall I put 650miles on the "racecar" in two days without leaving the state.
You need to consider the experience level and success of those giving you "information", and ignore the guys with the slow garage queens. If they knew what they were doing they would not have slow modified cars and if the actually DROVE their cars they might have a clue what the long term implications are of certain modifications.
I don't necessarily disagree with this statement, but the Opti-Spark didn't take any antifreeze baths either - when you change an electrical pump, it will only get on the Opti if the car is pointed uphill.In my experience the parts store remanufactured pumps work just fine. I have had the opti get coolant baths a few times BUT they always worked fine. ANY distributor will act up if it gets wet internally, people just BLINDLY hate the opti so much they ignore that fact and replace distributors that needed nothing but to dry out. If you are competent you will assemble it so that even if the WP pukes the opti will stay dry internally.
