electric pump yes or no?

i was looking for an easy way to add some power to my l67 ... i know a cam costs just about as much , but dont feel like tearing it all apart right now ... i have seen where people claim that the meziere electric pump can add up to 10 hp on top of better cooling over the stock belt driven pump. I was just wondering if its worth it , money isnt the question im just wondering will it do anything for my car thats noticable? O yea im also on club gp just figured i would come get some more opinons from people on here since they are most likely different. .. thanks alot guys!

The only Meziere electric pump I am aware of for our cars is the water pump. So I'll assume thats that you are referencing. When I read your title I first though you were possibly talking about a fuel pump.

At any rate.

The electric pump can be used reliably. I dont have one installed but it is in the works to get one and get it on. The do cool better in the respect that its not tied to engine rpm, so that gives you way better cooling in situations like summertime city driving.

They do NOT add horsepower to the engine, rather they free up horsepower. Think of it this way. Your engine has a certain level of output that it can give. But a certain amount of that power is required to drive the accessory items. So if it takes 10 hp for instance, to spin the belt driven water pump, then you will get those 10 hp back to be use to move the car. So your not gaining hp, you're just getting back what was being used elsewhere.

On my last vehicle I ran a complete set of underdrive pulleys, wp, alt, ps, etc. I think it was a 10% underdrive or in that area. What I noticed more than anything was better throttle response.

With the GP I would much rather see a complete set of lightweight aluminum pulleys for everything including the crank and then being able to run the electric water pump on top of that. I would venture to say more than 10hp could be reclaimed to say nothing of the throttle response.
 
I can attest that the electric w/p does free up a little hp on the top end and it does help keep the engine cooler in hot weather city driving. The only downfall I know of is, they have a short life span on a DD.
BUT... at the track... with the Caspers high speed fan switch added, less than 5 minutes between runs!
 
I would think the added current drain on the battery would require the alternator to work a bit harder. There would be more load added to the accesory belt but probably not as much as having the water pump on there.

Better cooling at low rpm's makes sense but does it flow as much as the belt driven pump when at higher rpms?
 


I've thought about getting one of these for a long time now. I donno if it be worth it though. I've heard others on ClubGP say it didn't help any and consider it a last mod for squeezing ever bit of HP out...
 
We have one over at NAIOA who has one on his L36 (not too modded) and said it feels better at the top end. Another is working on putting one on his heavily modded L36 (still N/A) and I'm eager to hear his results.
 
I love my Meziere.

I bought it through INTENSE, and got the Casper's wiring kit for it so I didn't have to cut and splice factory wires. Plug and play simple install.

I can attest as well, matching this with a manual high speed fan switch allows for extra quick cool downs at the track.

If you have a drilled t-stat even better results can be had.

In the pits, or staging lanes, turn the key to RUN, and turn your fans on high, and the pump will circulate the coolant with the engine off, and as it passes through the radiator the fans do their part. The drilled t-stat will insure that the coolant will still flow even if it gets cold enough to close the t-stat.

Though it does help to have a good power system.

My set up is a stock alternator (but has been rebuilt and polished by me) and a Optima Red Top battery. No alternator hot wire kit, or high out put voltage crap on my car. :th_thumbsup-wink:

I like my Meziere so much on my GP, I am going to buy one for my LT1 motor I'm stuffing into my Sonoma pick up.



~F~
 
I'm also looking at getting one , but have been told by many not to trust the thing on longer trips. And seeing as the tracks is a 1.5 hour drive from here, and the other one is about 2.5 hours.

I'd like the car to be running for more than a few weeks this year... should I put the WP on ? or ?
 
Hmmm...I may contact Meziere and see what they have to say about it being used on a daily driver.Couldnt hurt i guess. If i get some free time today:th_shakinghead1:
 


I bought mine in...lets see...'03 or '04, and have taken several long trips way away from home, and never gave it a thought about it going out on me.

A stock one can go out just like this one, and who doesn't know somebody in the club who has never had to replace their stock water pump?

But for the sake of protection, I carry a few extra fuses for it just in case.

~F~
 
Yea but with the mechanical pump you can hear the bugger going.

Oh well. Farns is the decider on this one, I'm buying one !
 
At a minimum (going to and from work) I drive around 2 hours a day. So, in simple math terms that would be 1250 days of driving to and from work. 1250 days is around three and a half years. I dont think thats too shabby for all it does.

I've never heard of the stock pump on a 3800 failing, but you could just keep the old one around for a just in case type of thing. For me, that would last more than 3.5 years.
 
I can attest to the fact they fail (mine locked up solid)

Stands to reason. Nothing is perfect.

And, the oldest 3800s I'm used to dealing with were the 2000 year model (when the Impala was reintroduced), so I figured they had to fail at one time or another. I just had no examples to cite. :)
 
cool , looks like i will get one later on down the road ... thanks for the imput guys! ... i mean mine has about 193k on it now [stock pump] so umm , pretty soon its gonna go and might as well upgrade instead of just replace :) :th_thumbsup-wink:
