What is best for a street driven car, 35 or 55 GPM?

 

Anybody??

 

Does nobody have a third gen camaro with a electric water pump? I find that hard to swallow.

 

I know of three.. all of them overheat constantly, seriously the electric pumps are not rated for "normal" street use.. one guy I know has a moroso that he cant even mount any accessorys to so his belt is constantly falling off the reason you don't have any answers is because it's a bad idea .. even the ones that say they are for street use don't work as well as an aluminum stock type pump will and not give you any problems with accessory mounting or no room for belts ...

 

I would agree that an Electric water pump is probably not the way to go with a daily driven camaro that see's stop and go traffic. But in my case it will be a weekend only vehicle with hopefully very little stop and go traffic. I'm looking into the CSR,Mezeire and Proform. I just want to know if the extra 250 bucks is worth the extra 20 gpm (55-60 gpm)Vs the standard 35-37 gpm units.

 

I would say if you are going to "street drive" the car at all I would suggest finding the largest capacity on you can afford It will not only help with the street use but cool quicker in the pit lanes at the track , just make sure it leaves you options for accessorys like the alternater and P/S pump if you have one , thats one of the biggest difficulties I have seen with the electric pumps is not being able to line belts and accessorys up so they will work together and not spit belts off all the time ...

 

Thanks for the info.

 

Exactly. I had to have a friend fabricate two brackets so I could mount my alternator to the wp.

 

Is that specific to the moroso or all electric pumps?

 

All I have seen dont include any mounting provisions at all for any accessorys which makes street use a PAIN.!!

 

Personally, I would never use an electric pump for street use.

If what you're after is max gph without horsepower loss, then get an Evans Cooling coolant pump.
Web site is http://www.evanscooling.com.

For 3rd-gen small blocks, the numbers are EP3122 (V-belts) and EP3122R (reverse rotation for serpentine.) See their on-line catalog.

At one time, these pumps were rated at 92 gph. I just went over their site, and I don't see that claim any more, so that may have been inflated a bit. But I have the EP3122R on my '88 Formula, and I can tell you from experience that these things move more coolant than any other performance pump. Combined with a good aluminum radiator (I have a Griffin), good fan, and proper lower air dam, cooling is NEVER an issue. Their impeller design not only moves lots more coolant, but it seems to do it without robbing a lot of power, too.

Tip: Remove the rear cover. Buy a Fel-Pro Performance rear cover gasket, and use "Indian Head" gasket shellac (available at NAPA) to reassemble. These pumps push so much coolant at high rpm that they will actually cause their own rear-cover gaskets to leak. But horsepower loss? I've never noticed any.

I have also used their waterless coolant, and was very happy with it. Zero steam pressure is great. But I went back to normal coolant because I was doing a lot of work on it and losing a lot of the expensive waterless stuff. My fault, not theirs. Once I'm satisfied that my present build is complete (I may replace heads later.), I'll probably start using the waterless coolant again.

By the way, I'm not connected with Evans Cooling. I don't get anything for recommendations. I'm just very happy with it.

 

Looking through Summit I don't see any that have accessory mounts. I have a Be Cool aluminim rad with a 12.5:1 383, and I havent gotten to the point where I need to turn on the fan. The pump is only 16-18 gpm, but does the job. A good rad makes a huge difference in heat transfer. Main drawback will be mounting. Like I said before I had a buddy who could weld fab some brackets for me. It was 3 years ago but I think we used some 3/16 or 1/4 plate steel for the lower alt bracket. Bolted that to the head in two places then to the lower alt bolt hole through which it pivots. The top bracket is a conglomeration of 2 or 3 gm brackets (looks pretty good. really) It has an arm bolted to the passenger side face of the water pump, and on the DS an arm going through both wp bolts. It arcs over to the top alt mounting hole where the adjustment takes place. The power steering is mostly stick gm. I had to cut one of the mounts off, I believe, and used some hollow tubing for a spacer. No problems throwing belts to 7000 rpm, but I NEVER would have been able to build, let alone devise, a way of doing this myself. It caused me to abandon my project for a couple years due to not being able to figure out a way to run my acc. BTW the you could only do this with a weiand. The Moroso doesn't have a flat face, and all the other ones I've seen are built differnetly from mine.

 

I have a 83 Z with electric water pump and fan. I purchased the custom bracketry over the internet and ran a low mount alternator and power steering pump as well as underdrove all accessories. I have had no cooling issues and thats with a cracked lower air dam that needs replacing and a STOCK radiator . I am putting in a different rad soon and a new lower dam though just for insurance. This all cools my built 383. I run a CSR pump.

 

Thanks for the Info. So not all Hope is lost. Is your CSR pump the standard 37 GPM or the larger 60 GPM?

 

the company march does offer accesory mounts for electric water pumps. usually they are not listed in catalogs. i got mine from jegs. they are specific to the brand of pump. both summit and jegs can order directly if not in stock. i believe the alternator mount and power steering mount were each about 40 dollars for the csr pump.

 

i have seen a few guys running electric water pumps on their street cars and are doing just fine. just make sure you got a good radiator and low thermostat and keep an eye on your gage. it shouldnt overheat at all. a radiator and low temp thermo will keep the motor cool.

you cant beat the hp gains that electric pumps offer. thats a big plus

just get one thats rated with alot of hours of operational life.

 

I have a Griffin aluminum Radiator for my 406. I'm leaning towards the mezeire 55 gpm or the CSR 60 gpm. We'll see if it works.


Yeah I have one of those MARCH kits for electric water pumps, For Sale. There are no provisions for use with a blower. I have to use Prochargers Brackets.

 

i just bought a CSR electric water pump, i bought it for my daily driver because i plan to make it my summer vehicle and itll have close to 450hp soon and i have the money now so i decided to get it. buying the pump was easy, finding brackets to mount your P/S pump and alternator was the problem, MARCH racing makes brackets and kits for every electric pump and every setup even with AC compressor.

an electric water pump in daily driving is still ok, you block will just be cold for longer and itll take some time for the windows to defrost (small price to pay for cool parts under the hood tho).

 

why do people go through all the hassle torun an electric water pump ..... Like how much power do you gian , 5 hp ? Ain't worth it to me IMHO . It's not like they will cewl the car any better than a belt driven unit , will they ?

 

anyone that has a problem mounting accessories with a electric waterpump..... isnt enough of a racer/car guy to need one.


whaaaa! my performance part didnt bolt on easily... whaaaa!!! geeze grow up a little.











anyway, theres literally 1000s of guys running the 55GPM pumps with no problem.... the 35s will work, if you have a good radiator and enough fan for when you're stopped in traffic in summer.... the 55s actually flows more at idle then your stock GM cast iron does.



D's89IROCZ:
they "cewl" the car better with the engine off then ive ever seen a belt driven pump do.... also, they flow the same sufficent amount, regardless of engine RPM.

 

I've had a Meziere water pump installed on my car for over 5 years now driving in stop and go traffic with the A/C on and I live in Florida. I haven't had any overheating issues yet. All hail Mezeire for making a superb product!
