CVFwater pump question.
« on: January 02, 2019, 04:44:23 PM »
Hi
 I wanted to order one of the CVF electric water pump for my 428 useing jayb's adapters.
They have a Ford #B-BBF-EWP and  I needed to know if this is the pump that every one is using.
This is the same pump I ordered for my 71 Ranchero [429] and if I remember correctly it flows 35 gallons per hour. The post I have read say they flow 55 gallons per hour.
I can't find a 55 GPH pump anywhere in their catalog.
This will be for a street motor that will only see the strip 4 or 5 times a year but I still don't want to over heat it in our Oklahoma summers where the temps in the summer can hit 112 to 117 at times.

Download the instructions at the link below.  The CVR part numbers are included in the instructions.  The one for the 429/460 is not the correct pump, CVR has a universal 55 gpm pump that is used with the adapters.

Thanks Jayb
I had read your page but didn't click on the instructions.
I am going to CRV's web site and check on the pump.
Thanks again
Greg

Looks like they have stopped making them as they are no longer listed on their site.
Guess It will be the stock pump.
Thanks for your help.

I think you might be looking at the wrong brand.  It is CVR (Clay Valley Racing).  Summit Racing shows them in stock, see the link below.  Just to confuse everyone, Summit uses the CVS prefix on the part number ;D  There are three other colors available besides the plain ones at the link below.

Thanks jayb
I must be getting old or something. I was confusing CVR with CFV.
Ordered the pump and will order your adapters as soon as I build up some more spare change.

One thing to keep in mind for using the CVR pump on the street..... The pump does not have an outlet for the heater core like the stock pump does. If you want to maintain your heater you'll need to drill and tap Jay's adapter for a fitting. I like the idea of keeping the heater in-tact for street use in case something goes wrong and the car is overheating.

thanks a lot.
I didn't even consider that but I will need a heater.
Your pictures helped a lot.

One other thing I just thought of. I can tap the other side for my sensor for my EFI.

I'm no EFI expert, but I believe they would want actual engine temperature. Tapping the adapter will give you the water temp flowing INTO the engine, which will be much cooler than the actual engine temp.

Good point.
 I will have to rethink that.

Greg,
I am in the DFW area and we have the same temperatures. I never have an issue with my 1967 Shelby GT 500. The only cooling system change made was the Edelbrock polished aluminum high flow pump. The radiator is the original Ford 3 row unit.

Here's one other thing to consider when using any electric water pump.  They don't have a bypass like the stock water pump does, which means that the water won't be circulating in the block and heads until the thermostat opens up.  Normally when the engine is cold water still circulates through the engine, by way of the stock bypass.  If that doesn't happen, by the time the thermostat opens the water in the engine is very hot, and you will get a big temperature spike on the gauge as soon as the thermostat opens.  It will cool down very quickly, but its still not a desirable situation.

There are two ways to skin this cat.  First is, as previously suggested, drill and tap one of the adapters for a hole, but instead of using a single outlet, put a tee there.  Run one side of the tee to the heater core, and the other side to the water pump bypass nipple coming out of the intake manifold, or in your case, the intake adapter.  If you don't want to do that, you can also drill 3 or 4 1/8" holes in the periphery of the thermostat.  This will let water pass by the thermostat even when it is closed, so that you will still have water circulation when the engine is running.  Those holes will not affect the normal operation of the thermostat, and the engine should still come up to the thermostat's rated temperature.  Just make sure that the holes are not covered up by the gasket when you install the thermostat.

Hi
Keith thanks for the info. I will be running a 3 row aluminum radiator so hope it makes a difference. I all so am adding a Vintage air unit to the 63 as I just like cool air in the summer.
jayb
 The ideal of the t in the line is a good one. I was planning to drill the holes in the thermostat anyway but had planned on 2 but 3 or 4 will be no problem.
Any idea where to run the temp sensor for the EFI and still have a Temp sensor for the gauge?
Again thanks for all the help.
Greg

All the EFI systems I've used, or seen, put the coolant temp sensor right up by the thermostat.  You can use one of the 3/8" pipe holes in the top of the intake adapter.
