CVR Electric Water Pump Adapters for the FE

Cool so you are ready to rock Jay, is this the longest thread ever LOL......Jon

Jay as always simply amazing work! A couple notes to this thread, but in full disclosure I have a 385 motor Mustang currently so take this with the appropriate skepticism or not.

I always end up using Ultra Grey Silicone on the smaller diameter o-rings that come on the CSR and Meziere pumps where they connect to the timing cover and block. Otherwise they eventually leak.

On the age old use a thermostat to slow the water down I'd refer everyone to the Stewart water pumps tech pages. They make NASCAR water pumps which are mechanical but they debunk that old wives tale for similar reasoning to Jay's

I don't run a thermostat on my electric fan/electric pump cooled street car. It currently makes around 1000 HP and does fine in all kinds of driving conditions including track days, auto-x and even pulling a trailer. I have two Drag Week jackets, not three or four like Jay but I think its proof that the all electric system can work.

Rather than try reverse cooling I'd suggest pulling water from the back of the manifold/heads to facilitate combustion chamber cooling. This means changing the size of some of the holes in the head gasket. I got my info on this proceedure from Jon Kaase at Engine Masters for the 385, I'm sure someone (maybe Barry R.?) as tried this on an FE.

I now run an Afco dual pass radiator which made a significant difference in a similar size form factor. Jay's setup allows that and I'd look seriously at Dual pass if you don't want to cut your radiator cradle.

Good to hear from you Bill, and thanks for the detailed info.  I'll watch those O-rings; hopefully they are beefy enough to survive...

I have already drilled my block and heads for more circulation and cleaned the burrs off the holes.Also cleaned up the block for better oil return. Does not everyone do this kinda like thread in oil journal plugs. Standard issue engine building stuff.

Looking back it is amazing to me that this took so long    I expected to be finished with this stuff a month ago.  Oh well, I'm in production now; here's a shot of some complete and some partially completed adapters:



There is an ad in the vendor classifieds and a link under the Products and Services button on the main web site for anyone interested - Jay

Ok so its roughly 10-15 hp gain for the electric pump. Any Idea what a SS flex fan or a non clutch fan uses?  From what I see 15-25hp can be gained from using both. Thats pretty cheap horsepower. I know the alternator will be doing more work but in a race car you can disconnect the alt for your quarter mile pass with a simple switch.  I remember my friend ha a car and we put a vacuum switch to disconect the ac compressor at WOT.

Car Craft fan test (sorry it's a Chevy!).

I did that test a long time ago for a guy on the FE Forum, but I can't find the data at the moment.  The test was somewhat suspect too, because the fan was just hanging out in front of the engine, not positioned right next to a radiator like it would be in the car.  But if I recall correctly the test showed about a 10-12 HP loss due to the presence of the flex fan.  For sure there's at least some horsepower to be gained by removing the fan...

Edit:  Never mind, I found it.  Here is the data:

looks like roughtly 20 hp to me. I recently installed a 4 core aluminum radiator and twin electric fans. I need an electric pump lol. That would raise my very dissapointing 415 rear wheel dyno results a bit. Since that time I went to a 3 inch magnaflow exhaust, Which feels like 100 hp over the flowmasters. and an 850 dbl pumper from a 750. I will probably find out at Beaver Springs Fe reunion what the 1/4 mile times are.

   I hear you there .... The only problem is the magnafolws sound HORRABLE ! I switched from flowmaster 10's to magnaflows and I dumping the magnaflows and going back ! I kid you not, the sound of the magnaflows drives me insane ! there like driving a stock muffler only slighly louder when you get on them.

 Im so glad my system has flanged mufflers for easy changing !

Just got the adapters today and started putting things back together.  Fits great and even the lower hose worked out fine.  Thanks Jay.

[jayb]

It's cool seeing those things on another engine 

[afret]

Put water in and found some seeping between the adapter and the body of the pump on passengers side.  Might be due to the really thin O-rings CVR uses there.  Took the adapters off, cleaned and put a thin layer of silicone there on both sides to play it safe.   I'll let the sealant set up and put it back on tomorrow.
Should be fine now.

[jayb]

Hmmm, I didn't see that on mine.  When you took the adapters off did you notice any burrs or anything on the adapters themselves that would have kept the O-ring from sealing?

[afret]

Nope, no burrs, the adapters looked really good. 

[jayb]

cdmbill said that he had to use a thin layer of silicone on his CSR pump to get it to seal despite the O-rings; maybe that is just going to be required in some cases.  I think I'll add a recommendation to that effect to the instructions sheet.
