Standard or Electric Water Pump?
I'm going to order a new Dyna-spark unit tomorrow for my 93, the original is DEAD.
I will take the forum advice of replacing the WP while I'm at it, and also my Intake Gasket as it is leakin oil from the front & rear. My OPTI probably has oil in it due to my leak ( I get about a 50 cent piece size puddle on the floor over nite after running the car).
How do I decide which type of Wp to my?
My car has 18k miles, I only will put abour 2,500 miles/yr on it. I don't take it to the track, only to cruises or shows. Sometimes some spirited driving on the open road.
What are the benifits of electric? What are the downfall?
Do you use a diffent belt, as the pully is gone? How does that work?
How do you wire it it?
Thanks

The LT1 water pump isn't belt driven in the first place. That's what makes the LT1 the perfect candidate for the electric pump.
I've written it all up before so I really don't feel like typing it again. Take a look at my web page here
http://www.wku.edu/~nathan.plemons/h...rformance.html
and read the section on "The Water Pump." That should tell you all the basics, if there's something not answered there, feel free to ask.

The belt is the same. Since you have the LT1 the WP is driven off the front of the cam. I have the Electric on my LT4. I love it. I drive it HARD. the only issues with installing it, are removing the stock WP drive from the engine. And closing the hole in the Timing cover. the electrical part is a peice of cake. the benefit is a constant flow of coolant and cooler temps. It should free up a little power, but it is one more load on the electrical system. Over all, I say do it...

I just did what you're proposing to do.
The electric water pump conversion has a great tech tip already written up bt Strick... https://www.corvetteforum.com/techti...=231&TopicID=2
Benefits of the electric pump:
1. No hole through the timing cover to leak.
2. Easy to replace the pump compared to stock when it does break.
3. Imperceptable HP increase.
Drawback:
1. You have to pull the timing cover off to weld up the water pump drive shaft hole. (which requires a ton of work - and the oil pan has to come off)
2. It's expensive.
3. It's not indestructible
The biggest deal is having to weld up the timing cover hole. Then the drive gear has to come off (which is driven off the big sprocket of the timing set.)
I had oil pan leaks anyway - so I figure what the hey! If I had to do it all over again, I might have stuck with stock.
There is no belt change because there isn't a belt on the water pump. It's driven from the back.
The wiring information can be found in the tech tip

Actually, you don't really need to do anything to the hole. If you were really lazy, you could just leave the gear driven stub shaft there and leave it at that. That way you don't need to remove the cover to do anything. I had the engine out when I installed mine and actually used an appropriately sized freeze plug. No welding required.

I did the same on my 383 i forgot what size freeze plug but i looks a lot nicer than welding the cover
