Electric Water Pump???
I know this has been discussed to great lengths and I've even seen previous posts on the subject here, but can't recall them now, nor is a search fruitful when you type in "Electric Water Pump".
What are the CONS of running an electric water pump? In other words, what do you need to be mindful of? (high volume, high pressure, get better battery, better amp alternator for increased amperage load???) Also, is it really worth it? For $350, does it free up that much power?

They can fail suddenly and leave you stranded. Some people dont get good life out of them. The only advantage IMO is being able to use a standard type double roller timing chain. Only frees up 5-7 hp.

I don't know if they are worth it. I used one because I want to cool down the engine quickly at the track without starting the engine.

And that would be IMO the biggest advantage of one... being able to keep coolant flowing without the engine running. A helpful feature if you have a car that sees alot of drag time.
If you do any other kind of racing with sustained high rpms such as autocross or road course, then stay away from EPs. They wont flow as much as a stocker, especially under such conditions, or so I've heard.

Sounds good to me... didn't really want to drop another $350 anyway.

So wait a minute.... you're telling me that you bought an electric water pump and it only lasted 2 years and you

Oh yeah that's right, you've got an LS based engine. How much more difference in tensile strength/ stability would you think the LT4 extreme duty timing chain (my current chain) and the stock LS2 chain have? Any ideas??

I put a meziere on my 95 and i traded out to a double roller chain cloyes clo-9-3145 i did have to clearence my timing cover nothing major works great but you have a 96 and a crank sensor you have to ditch the sensor and have a tune disabling the crank sensor to get rid of the reluctor ring

not if you convert your pcm to obd1 then you dont have any downstream o2's or the crank sensor the crank sensor kinda helps out when you have a missfire it will tell you what cylinder is missing when you get an ses light,thats why with a obd1 system you never get a specific cylinder misfirse because no crank sensor other than that thats all its good for IMO pcm for less can delete it thats where i got my tune

Already deleted the downstream O2's.... but hmmm, food for thought.

The LT4 ED chain set is good. You will be good to go with either that setup (if you want to keep a mechanical water pump) or a good standard SBC double roller (any name brand one will be a stout piece) if you will switch to an electric pump. I would definately get one or the other though as it will be a blown engine with an already increased load on the crankshaft.
