my csr pump runs hotter on the highway then at idle. Thats because its fowing the same at idle or at 2500 rpm. Where the stock will flow more when at higher RPM's since its running ogg the engine. So when its flowing the same at idle for 2500rpm, its gonna run hotter because it cant keep up. But mine still isnt breaking the 210deg. mark when im crusing at 70mph with 3.73's and 2500rpm.


And as for the power gain, deff. for sure. When i had mine off i was spinning the prop with my fingers and it was pretty heavy, now imangine that trying to flow heavy liquid through the motor. DEFF! a power loss there. I deleted all my acc. and only running a alt belt and EP, no power steering...... my motor revs so much faster because theres nothing dragging down the motor. Sounds like a built motor whth how it sounds. Its all about making everything run effciant = power.

 

with the E pump it is not going to make any difference on the alt.... the Epump barely uses any power to run at all and is not even noticable on the gauge...i have had mine on for about 6 months now and noticed no change in charging, but havent been to the track to see any diffence in times..

when i placed mine on i noticed no diffence in temp either... slightly hotter on a summer day on the high way... but i never get over 195 deg...

 

especially if you run it off a relay, which you should do anyways!! That was just retared to say about the alt. power thing, lmao.

 

I did before and after dyno testing on a Mustang dyno on the same day and got 9-10 rwhp across the entire tested rpm range using the Meziere EWP...I do run a bit hotter at cruise which was explained earlier due to the EWP turning at a constant speed regardless of engine rpm, consequently I'm way cooler at idle and in traffic, which is a big plus...Mine is wired with the Painless wiring kit with a relay and has been great for a year...If it fails, its way easier to unbolt the EWP and replace it with another...I'm thinking it should last me 4-5 years...I think its a good mod...

Okay, it makes sense now. The electric pump simply pumps less water than a mechanical pump at anything above idle, and that's how it takes less power away from the engine. That's fine as long as it prevents the engine from overheating.

 

no dude... it saves power by not having the cam dragging the pump gear... you remove that and it just less drag on the cam/timing chain... thats how it saves power...

 

exactely, case closed!

 

But, how bad is the car driving and steering wise after you deleted the power steering. I may decide to go down that road one day if it isn't to bad.

 

sucks.... period

 

Your just not getting it man.

 

hey, how do you get the e pump to run when the engine is not running?

 

I wired mine up to a relay which was wired up to the ignition IIRC and I can turn my key oin and it run but the engine is off.
Also on ws6.com they picked up like 8whp and 10rwtq

 

Yea me and my dad wired my EWP on a relay. It has run great ever since iv had it about 1 year. Its built to not leak on the opti when it goes cause the weep hole it relocated.

 

ALSO changin and EWP only take a the outer bolts on the WP housing and its done. You dont have to pull of the whole thing after you install your first EWP. Thats why I got it...well the few ponies didnt hurt anything...besides my tires.

 

I got skinnies on the front so for me its fine. It doesnt "suck period", some people are a**holes. Its personial opionion, i like it. PERIOD. BAck to the topic and help him understand a waterpump. thats what were here for.

 

thank you for calling me an *******... its ok that you drive a race car

 

haha, i called you a A "star" "star" HOLE, he he. Everyones car on here is a race car.. you race it and it becomes a race car. My moms geo is a race car. This is retarded.


Just buy a EP and be done with it. Its worth the money!!!!!!!!!!!!!!!!!

 

pretty much, and the electricwater pump operates at a constant RPM if i'm not mistaken. and the alternator should be able to power a water pump just fine because i dont think that with what all is on the car right now the alternator is at its maximum capacity

 

I understand what you are saying. I also agree with you. The EWP is performing less work than the manual pump. If an EWP pumped the same amount of water, there would be little or no power savings because of the extra drag from the alernator.

Electricity is not free power. That's why a 5,000 watt portable generator uses a bigger engine than a 2,500 watt unit. As the amount of electricity used increases, so does the amount of work required to produce the electricity.

 

lots more difference in 2500 and 5000 than there is in a 100 amps and 104 amps. I think the EWP takes a whopping 3-4 amps to run... not gonna cause a loss of HP. It is retarded to think it is going to slow down due having to run a 4 amp EWP. I mean I can see where this stuff makes sense because when I hooked up that amplifier in my car I slowed down 2 tenths and 3 MPH... oh wait no i didnt
