View Full Version : I want to dump my water pump.

I see all types of cooling mods, under drive pulleys, Mazmart replacement water pumps.

I want to throw away my water pump.

Yes, I want a plate to replace my pump, and use a remote electric pump.

:naughty:

Knock yourself out.

Its not like your alternator is doing anything important, anyway.

That's it!
Eureka, The electric alternator too.....

I have a 40 GPH pump in mine...still in the testing phase...mounts up sweet...and looks cool....

You don't need the water pump to operate the alternator. Since the belt adjustment is on the alternator all you need is a new belt with the appropriate circumference/length.

I was wondering what the appropriate sizing/flow rate might be relative to radiator capacity/fluid dwell time?

I think that an electric water pump would resolve the whole cavitation at high RPM thing.

We will see.......It pumps a lot of water......:) Still testing the temp stuff though so no comments yet

BTW...so I don't forget later..the belt length would be a 300 series...or 30" belt

Anyone know where to get a 5 rib 30" belt :) I have a 4 rib Gates belt on now...but they don't make a 300 belt in the 5 rib style...

It has much more wrap without the water pump pulley...so I don't think there will be a problem with it slipping

lol :evil_laug

But how about the other way around?

I wasn't talking about the belt.

I was talking about the 8 amps it pulls from an alternator that already gets up to 280°F from the load it is under in normal operation.

I think that an electric water pump would resolve the whole cavitation at high RPM thing.

What makes you think there is a high RPM cavitation issue? Data?
Do you know how many GPM the OE pump flows across the RPM band?

nice edit :evil_laug:evil_laug

It's not a cavitation issue per se, there are a number of reasons for doing it

try reading the other responses too, somebody has to start somewhere and more than one person already is

don't you have customer's asking silly questions to attend to instead? :cwm27:

What edit? Read what I posted more carefully.

I wasn't talking about disconnecting the alternator, I was talking about the fact that it is already overtaxed.

I guess my post wasn't dripping with enough sarcasm.

No. I have enough time to deal with all the silly questions - even this one.

Pump draws 4A......even less running :)

No stupid stereo or anything else drawing a lot of current.....should be OK ;)

go man---i talked about this over 2 yrs ago and i called Merize(spelling) and others about it.
The concept seems taylored made for us. Just think of the increased cooling at low rpm's and stop and go traffic. Since the ewp can provide CONSTANT speed of circulation (a 2 speed pump can be done) ---it just makes sense. Besides stopping a 5-7 hp parasitic drain aint bad.
You can also program a ewp to continue to run after you switch the car off for a set amount of time.
Remember years ago we never though we would have electric power steering either!
Now I was never able to get a firm figue of the flow rate that was needed for our cars. I did logically think that if they could cool a high hp v/8 then it should be ok for us. But???
And on a side note --if you ever need to pump you basement out---taadaa!
Like to be in on this with ya.

Doing it right requires manifolding the pump outlet directly into the irons, but that's a tale for another day ....

I sent you an e-mail on the 8th regarding your website. No worries at all I thought maybe it might've been spam filtered or something since its not an address you recognize. Its signed with my name and my handle on here.

Dan remount the alternator down where the a/c used to be---you dont need that anyway do ya?
I have been thinking about that but I have other stuff going on---my poly motormounts are working pretty good now.
True what MM said --the dang thing gets HOT--i have melted the edge off the belt before.
I think our 5 rib gaterback belt is 31inches long?
What temps things are you seeing?

So far I haven't driven it much...and the weather here is cool..so it's difficult to tell right now how well it works. The pump is used on high HP V8's so it should work on our little barrels :)

I have it running on a turbo timer type circuit off the Haltech, and that works sweet.....can run after the car is off.....that really cools the engine off a lot faster.....especially with the fans on :)

PS: used a remote mount pump...alternator is in the stock position and the pump mounts in a sweet spot.....

I don't see the point on a street driven car. It won't last anywhere near as long as an OEM waterpump and it will put additional strain on your electrical system.

can run after the car is off.....that really cools the engine off a lot faster.....especially with the fans on

and drain the battery more. running the fans on shutdown is good enough.

Lets see........4A drain.......likely less when it's running.......should run for a long time ;)

Way less than the fans.....

As far as cooling....the fans on and the pump running will cool it down way better than just with the fans alone............


who said anything about a street driven car...unless you call driving to the track " street driven" The trailer is the newest MOD for the car....
