$800? Is that a lot for a water pump?

 

How does the stock water pump cause "costly supercharger replacements"?

 

Thread to discuss the R53 Electric water Pump from 1FastMINI

 

+1 I would like to know since I no longer have a warranty.

 

The water pump on a MCS is bolted to the back of the supercharger, which is what actually what drives it.
In between the two is the water pump drive which consists of two fairly thin gears that mesh together. There is lube for the gears when the supercharger is assembled, but over time it appears that the lube is pulled past the shaft seal and sucked into into the supercharger. Once the "gear case" has been sucked dry, the water pump drive gears will self destruct, and you will have no coolant circulation.
As far as I know, there are no replacement gears and the water pump drive only comes with a new supercharger.

I'll see how the exchange rate is doing here vs the USD on the 20th of Oct. The dollar has gained crazy in the last week! Hopefully it will come back down in 2 weeks time.

Just a quick question, a supercharger will only fail once the pump dies correct? Or are there other ways it can break?

 

Yes, as of now the failures we are seeing are due to the water pump drive.

 

Thanks for the clarification

 

Were any of the failures perhaps due to high percentage SC pulleys?
This is the first time I've heard of SC failures due to the water pump, though I'm sure it is possible.

 

If I may interject....

It's been seen time and time again where there is a S/C failure it's not so much the S/C that failed but the water pump gears hanging off the end. The ones that we have seen here on NAM have run out of the oil in the water pump area and the gears grind them selves to bits. Water stops being pumped, heat builds, bad things happen. So it's not really a S/C failure that people are calling a S/C failure. See this thread https://www.northamericanmotoring.co...ead.php?t=7467

There has been no correlation made at this time with good hard data that changing the pulley, whether it be JCW, 15, 16, 17 or 19%, has contributed to the failure. That could be there is not enough data logged to see it as trend or it could be the pulley is not an issue.

 

Thanks for clearing that up, will def be interested. Need to wait until 20th and see if our currency improves. It went from 1:7 to 1:10 to the dollar in one week. All since the bailout - hoping it comes back a little by then.

 

Hello, great forum!

I am curious- has anyone installed such an electric water pump system?

Are there any photos available of a finished installation? How is the open end of the supercharger covered up?

Where is the 'new' water pump mounted? same place- or are there new hoses in the set as well for a new location.

And lastly, is it necessary to repair the 'old' water pump gears on the supercharger- that are usually worn out? Do they have any other purpose other then driving the stock water pump?

thanks,

 

There are pics in my gallery.

Pump is mounted in the stock location.

No need to repair worn/broken water pump gears, just install our block off plate and go.

 

thanks for the quick reply,

 

A few questions regarding your set-up.
1) is the thermostat removed and the flow managed by exclusively by the electronic controller?
2) Is the controller analog or digital?
3) What temperatures can it be set at?
4) What are the min & max flow rates from this pump?

 

Holy crap...the electric water pump is 900$ now... how much is a normal water pump replacement?

 

Rebuild Super 450.00
water pump 217.00
shipping guess 60.00
with out labor 727.00

 

Actually, I have never found any damage to the shaft seal or proof that the oil is sucked into the supercharger past the seal (though it is possible). The
thing I notice when rebuilding the rear gear drive is the lack of sealant between the plate and the rest of the housing. Of course I don't get to
see the car (if there is proof of oil under the supercharger near the seam).
Either way the oil does escape and the gears do fail very quickly. I have after about a year of testing and such now replace the drive gears (as well as the shaft seals, bearings, etc.) The biggest problem is the stock gears always made a bit of a whining noise, and my replacement gears do the same (even a little louder for the first 500 miles until they wear themselves in). Our magnetic oil fill plugs we install make sure that any bear or gear particles stay out of the oil after the break in period. But I love to hear any
information from the user end of this problem. We only get to see the results of the failure - never during!

what are the contact details for this guy? tryed the email no response...anyone know how to get hold of him?

 

1FastMINI is now E2 Services... you can get the contact info from the website at: http://www.e2orlando.com/

On the r53 super charger the m45 the seal goes bad on the pto end plate and behind the pto gear on the end of the sc. This dosnt mean the sc is bad it just means you have to fix the gears, bearing and seals sum which have to be pressed. Easy fix is ewp80 electric water pump cost about 200 250 shipped an if you also purchase the controller "extra" 150 200 you can have control over engine temps unlike a new stock water pump that runs off the belt thru the sc. Your choice

 

Tbird... I am going to go with the Davies electric water pump, but the question in my head is replace bearing/seal that seem fine otherwise and instead maybe fill the chamber of thicker gear oil that might not be so easily sucked through? My thought is if the oil was sucked through, I don't want the bearings now being dry and going bad if I caught the issue soon enough. I've read taking the SC apart to get to these bearings is of high risk regarding timing if not marked and ensured put back together correctly. I have access to a press but am also having issues finding the correct bearing online, so figured I'd just have to go to the local bearing specialist shop. But if I can save myself some time and go my alternate route, I'm thinking I should be able to rack up several more miles. Thoughts? Thank you
