ttocs Posted October 17, 2013 Report Share Posted October 17, 2013 Curious what people thing about these? When/while I have my motor out to smooth the engine bay I have considered one of these but wasn't sure what the real story was. I know it can free up some hp and I have a 200 amp alt so I have the power to spare, how is the reliability? Link to comment Share on other sites More sharing options...
Sleeperstang1994 Posted October 18, 2013 Report Share Posted October 18, 2013 i plan on putting one on my motor. The older pumps did not last very long. however a good quality pump from a company like meizier or moroso have a decently long life. Link to comment Share on other sites More sharing options...
iRoush Posted October 18, 2013 Report Share Posted October 18, 2013 if you plan on any extended high RPM's don't do it. Electric water pumps spin at the same rate at all times, they do not speed up or slow down like a belt driven pump would. You could PROBABLY get away with it on a daily driven vehicle, but I don't know of too many that run one for anything other than drag racing.

It's not going to hurt the motor in a 14 second or less pull. I'm talking about road racing you're just asking for since you're constantly at high rpm.

Schiffy Posted October 18, 2013 Report Share Posted October 18, 2013 I had one on my 351w powered fox, but that was ring built solely to drag race. Link to comment Share on other sites More sharing options...
ttocs Posted October 18, 2013 Author Report Share Posted October 18, 2013 ah gotcha - racing - funny I forgot there is more then one type.... I am good to stab it every once and a while but mainly happy just to save my tires and try not to draw any unnecessary attention to me so it shouldn't be a problem there. So then I guess is just the question of reliability. Link to comment Share on other sites More sharing options...
Duff Daddy Posted October 18, 2013 Report Share Posted October 18, 2013 Reliability is there,but anytime you change a mechanical to electrical system, you will ALWAYS lose reliability. Also depending on the pump/motor it will change how soon you will need to have the unit rebuilt. Current rebuilds from Meizier is in the 150-175 range + shipping. But remember they dont call them miserie for no reason. I have one on my car, All was good once I took care of a clearance issue from impeller to block.

BMW manufactures these so it makes sense that they last but, aftermarket companies not so much. some people have failures after 2000 miles... but others will last a lot longer. There's just no consistency to the part. Link to comment Share on other sites More sharing options...

My 3 series pump lasted to 90k miles, but I've read accounts of people having them go out at 5k miles and multiple times. Link to comment Share on other sites More sharing options...
Duff Daddy Posted October 18, 2013 Report Share Posted October 18, 2013 you cant really compare a factory part to an aftermarket ..... r&d build specs, parts, life expectancy ....wayyyyyyyyyyyy different. you buy a new 40,000.00 car or a used car with a 300.00 pump..definatly going to see some differences.

ttocs Posted October 18, 2013 Author Report Share Posted October 18, 2013 not sure why we can't compare stock/aftermarket personally yes they are different, could not be any more different but there isn't a reason we can't say it is or is not as reliable as the stock piece in the name of freeing up hp for the motor.

copmagnet Posted October 18, 2013 Report Share Posted October 18, 2013 5HP isnt really worth the 350$ IMHO. you can do march pulleys and free up more power while maintaining a mechanical pump.. Link to comment Share on other sites More sharing options...

I was just using this point to counter iRoush's claim electric pumps were no good for daily drivers. BMW doesn't even make the pump, so my point is sill valid; electric pumps seem (in my very limited experience) to work just fine in a daily driver. That being said, I probably would never spend the money to replace the mechanical pump that is functioning just fine. Link to comment Share on other sites More sharing options...

At that rate BMW or Brand X if you will, would have it put in to their 10 or 15,000 mile service to have the waterpump rebuilt....... see where im going with this Link to comment Share on other sites More sharing options...

I was playing Devil's advocate. I've actually gotten lucky with my two electric BMW pumps. One lasted 90k miles and the other is at 80k (will probably die now that I said something). There are a ton of people that have dead BMW pumps around 15k miles. Link to comment Share on other sites More sharing options...

Froush Posted October 18, 2013 Report Share Posted October 18, 2013 I actually just bought one cheap that needs a new impeller yesterday. Only reason i got it is because ive been stranded twice where i shredded a belt. This was when i was still trying to get everything aligned. With the electric pump, i can actually drive the car until the battery dies. lol. I do carry an extra belt and tools now but thats not the point Link to comment Share on other sites More sharing options...
revhead347 Posted October 20, 2013 Report Share Posted October 20, 2013 Funny how all that works. I think just about every car has electric power steering now. They are getting rid of all kinds of mechanical parts in airplanes and replacing them with electrical components. I am not a fan. There must be 50 damn computers in the airplane I fly, and it really drags on you. Always stuck somewhere because some computer is giving you a nuisance message.Kurt Link to comment Share on other sites More sharing options...
ttocs Posted October 20, 2013 Author Report Share Posted October 20, 2013 looks like it has its good and bad points just like everything else but sounds like we don't have much real-world exp with them actually in mustangs for me to say its worth taking the chance for me. Thanks fella's I will certainly end up spending that cash somewhere else... Link to comment Share on other sites More sharing options...
Duff Daddy Posted October 21, 2013 Report Share Posted October 21, 2013 To summarize 1) electric water pump, is just and idler or removes the pulley all together depending on the set up. 2) makes more hp available 3) has a rebuild spec which needs to be followed to prevent failure.4) Unless this is a track car which will see the occasional car show or meet, don't waste your money.
