If it goes bad in the remotes of TX, see the above post about the creek and the paddle! With that said, I'm already regretting not having went with the CSR or Meziere. Maybe once the bugs are worked out I will take care of my oversight. This has been a good read.
Thanks,

Interesting thread...

I chose a bit differnt route...

Low tension Radius tooth belt drive is fairly efficient as the tooth rolls in the pulley. I worked with the engineers at JRP to get drive ratios in line with my usage... I have street gearing for my accessories and race gearing. I also opted for an overdriven water pump and alternator on the street. I have no issues with lights, ECM, Electric Fuel pump, Main SPAL Fan and Aux Fan for the oil cooler with Denso Race Shop 86A alternator. Idling at 800 RPM. The beauty of the alternator is that it is internaly balanced and blueprinted and dyno tested to hold together at continious High RPM's. I lunched two Delco over the counter remans with 5800 Engine RPM bursts.

Thanks for your support, as this is what the forum is all about

Hey, maybe we will see each other on the road someday...and not on the side of the road because of an elec water pump

I am 1/2 hr north of dallas if your close let me know.

Forget about an electric water pump. go with a team G or
edelbrock.

This is something I found on the howard stewart water pump website

Yes, I have. I think the electric motor looks stupid. Just my opinion. I have a factory pump, no fan, and no shroud. Looks pretty clean to me.


Agreed.

I've got a brace, too.

And how often is that necessary?

I can, too. With a hose. Several flush/fill kits out there to do this...

True, but why not let the engine idle for a few minutes? With my setup, I've never seen the engine break 200 degrees, and that's running normal a 50/50 mix.

There must be some secrete NASDAQ stock out there for mech water pumps since most folks are telling me to buy them.

I guess some folks will never see eye to eye and that's OK..it's what makes the word go round and round. Imagaine where we would be if everything and everyone was the same.


By the way nice set up.

Darin... Welcome to TX...and the temp has definitely increased since we did the AER show a month ago!

What was your final decision (electric water pump or mechanical)???

I'm also about to go with an electric fuel pump and would appreciate your insight on this decision / design.

Thanks... Ed

Hey Ed!! WOW it did get hot. I am actually visiting home this week and it is only 55-60 since I have been here....cold!!

For now I went with the mech version, but I want the CSR elec version bad. I just dropped in the new engine and installed a new March under drive pulley set up and was worried about an elec water pump and a dual elec fan. I do not want to replace the alt again because of the lack of power (amps). I also need to install an elec fuel set up to do the NOS correctly so that is even more amps.

There is so much to do as I am in the middle of switching everything over to AN fittings throughout the car.

So you about to install an elec fuel and water pump?

What show is next on your list…we should get together again soon.

Darin... We just returned from a week in Colorado...nice about 60 in the mountains...back in the DFW heat now... 104 today!

I did the March underdrive pulleys with an Edelbrock water pump, Dewitt radiator and dual spals... no issue with the cooling...in fact one comment I read was that the reduced flow allowed the radiator to work more efficiently as the water is in there longer...don't know about that theory...but all is working Great for me....you should be OK.

The alternator was a different story.... the reduced pulleys slowed down the unit to the point that it would discharge at idle and really struggle when the fans were on and low engine RPMs. I ended up removing the new pulley from the alternator and went with the original chrome pulley that came with the unit... all is OK with the charging system now.

I'm going to need to do something with my fuel pressure as it's been dropping for the past couple of weeks....now about 2.5lbs...must be the pump giving out....filter is OK. Am thinking about going with an electric pump as I really liked your NOS setup at the show. Have some questions for you on the NOS the next time we are out.

We should check out the Cruisers or Burger Street shows when you are back on the road. My 80 is back at JBs getting some small items taken care of following the exterrior facelift.

Thats why you run a thermostat. It will control the flow of water through the rad and thus control the output of your pump.

lebvette

That's what I was wondering about. It seems like the thermostat is the most restricted area of the system....so only a certain amount of water is going to pass through, no matter how much you are capable of. Larry

The next time your head is under the hood of a vehicle with electric fans, listen to the engine rpm's drop momentarily as the fans come on. If it weren't for the computer idle speed control motor, the rpm drop at idle would be significant, proving the additional load on the alternator uses more engine power. The same principal is used on "Eddy-current" dyno's. The engine is loaded down by changing the magnetic field around a generator...

Check out the Stewart mechanical water pumps (thru Eckler's), mine made a big difference, and it was under $80.00.

anybody rebuilt their W/pump ?????

Ed 2.5lbs? What is the PSI and do you have a regulator? If you thinking about the NOS than I would strongly suggest an elec. fuel pump if you have to buy one anyway not too expensive and it will be done right. I put in a Holley mech. fuel pump for the Holley 4150 with a regulator and all is fine. I am actually going to do the same thing for the NOS by adding a new dual fuel metering block. One fuel inlet for the 4150 regulated and another for the NOS regulated. This way both can be independently regulated with the proper PSI.

As soon as I get back I need to take off the Holley and clean her out. I needed to get her back in my garage before I left for vacation and skipped the fuel filter. I just mad it home as the mech. secondary float got dirt in it and stuck open. Now it always thinks the fuel bowl is empty and poures fuel in all the time.

Talk about black smoke…..

I can get together as soon as I get back and clean the Holley out.

You could I think, but it would not be worth my time, maybe yours though.

125 bucks or less and you have a brand new one.
