are there any gear drives for lt1? thats the leet way to go.

 

I think there was a post about this a week or so ago, dont think gear drives will work on LT1's

I remember seeing someone who did a gear drive on an LT1, he had to grind some on the timing cover for clearance but did get it to work

 

Maybe Summit has a new pump but i thought most of the other pumps are only rated for 2500 hrs. Also once the pumps stop you almost instantly over heat. My buddy had a connection problem on his pump and the pump would just shut off sometimes and instantly peg red on the gauge. The Factory pumps may start leaking but at least they usually still function some what. I've had my ED LT4 chain on now for 1.5 years, 20K+ miles, and many 6k+ blasts. No problems here. Last i knew the LT4 ED was the only option. I did use the Cloyes oversized Crank gear with mine to help take up the slack. LT4 ED's are known to be a little loose with out one.

 

true. EWP's simply stop when they go out and youre screwed since its more than likely to take your opti. stock mechanical WP's can go out over time to where your car will still run, but it wont just stop working and most likely, if you find its leaking in good time, your opti wont be affected.

 

I dont think if the electric wp burns out that will make it leak , wouldnt it just stop spinning ????

 

where does the water go? id imagine that the EWP itself wouldn't leak, but once it stops and your car overheats, the longer you drive on it the more prone it is to springing a leak through a gasket.

 

First of all...once any WP stops your engine will begin to over heat. If the pulley comes off of a mechanical or the fuse breaks for the electrical. Either way they engine will begin to heat up.

Second of all...The EWP will get rid of alot of the drag from the mechanical WP. Your engine will, in some cases, remain cooler. The only thing you need to watch out for with the electrical water pump is the fuse to break...which is why you carry fuses in your car. Or if you had problems wiring it which is what seems your friend had.

Third of all...it is the same price to go with the LT4 ED and the EWP with a cloyes timing set, and you get more bang for your buck.

The EWP will work better for my application because I dont drive the car in the winter at all...and rarely at all cause I dont have it here with me while im away at college. The car sits in a garage and goes out on weekends. I guess it depends on your situation also.

 

Correct!!

 

1. Obviously once the pump stops the car will begin to over heat. What tends to happen on water pumps is the seal goes out and then the coolant starts to leak out the weep hole. It isn't long before the coolant eats up the bearings in the pump after that, but it usually isn't an instant thing. They tend to give you a little notice, unlike an electric pump. Also we don't have a pulley to come off of our pumps. They are cam driven. Go out and take a look at your car.
2. Yes the electric pump will get rid of drag but there are certain things some of us like to have. I like to have a "safer" water pump system, just like i take on the loss of power caused by using my powersteering and AC. Once the pump motor goes out it will blow fuses constantly. You will go through your little boxes of fuses immediately and not make it 10ft farther down the road.
3. The Cloyes set is actually alittle more money than the LT4 ED, but once again i want the "safety" of the mechanical pump.

Yes i know the wiring problem is partially my friends fault but he does very good quality work on everything he does and doen't half *** anything. His waterpump install was very clean and the wiring job was excellent to. What i'm getting at is if one little thing goes wrong, a loose wire, or whatever your pump can stop and you can blow a head gasket if your eyes aren't on the gauges at all times. Then that better "bang for the buck" mod just bit you in the Azz big time. Thats just my opinion though. I know others have theirs, but I wouldn't ever run an electric pump on a daily driver car.

 

the small gains seen by an EWP over the stoch mechanical WP can be made up elsewhere. id rather have the peace of mind in having a mechanical, cam-driven WP instead of depending on yet another electrical component.

 

That was my bad. You are correct about the cam driven..i was getting confused.

Like you said, i dont know if i would put one on a daily driver...maybe i would...but like i said before..it depends upon the situation.

Another thing...since I will be down there anyways and putting in a new cam...why wouldnt i want a little more gain?? There really isnt anymore security over an electric or a mechanical...either one can fail at any time...you must be ready either way!

 

mechanical WP's last much longer than electrical ones do. That's a given... Retard your timing a bit more or lean your a/f ratio out to make the gains seen with an EWP, and retain your peace of mind...but that's just my opinion...

 

you can ride around with your belt off longer if you keep the mechanical waterpump. (just saying)

 

Im curious about this...How so?? if you dont mind me asking.
