V8 guys, Electric water pump?, Is it a solution or asking for trouble Options

[Cheapsnake]

I just saw a thread on a water pump failure and there was a comment about electric wp's being not a good choice due to their lack of longevity, intended mainly for drags and short runs.

I'm just about to install an electric pump in my Rover 3.5 conversion when I saw that, but before I do I'd like some input from those that have had real experience, good and bad with electric pumps. and while you're at it, throw some make and model out there.

Thanks Jamie, you just dashed my hopes for just ONE job that didn't require hacking and welding. (IMG:style_emoticons/default/headbang.gif) However, since you've been there, I have to give some credence to your predictions.

Mark, do you have any more info on that pump you're using? It looks just like what I have in mind, but they are not too common an item.

Drive-ability, the engine is a Rover 3.5L, the LT-1's little aluminum brother. It's actually a British reincarnation of the Buick 215 that Jamie is running. I'm building "the mutt", 3.5 block, 4.0 heads and headers (higher compression, better flow), Buick timing cover, valve covers, intake manifold and oil pan, ...... With a boosted cam, higher compression and a few other tweaks, I'm guessing to be in the 200 - 210 hp neighborhood - just enough to get me in trouble.

I've been promising Jamie pics for some time now but every time I think I can actually finish a job worthy of pics, the mutt throws me a slider. However, I think I'm through the hard stuff and hope to have the tranny mounted this weekend and THAT will be an occasion for pics. Stay tuned.

It may be doable Tom. I think with the right pulley in front of the harminic balancer you can move it back some. Mine is a dbl pulley with the belt on the outside to line up with my pump. I am sure without my water pump as it sits I could move that back at least another 1/2-3/4". It might work but it will be very close to the firewall there. My alternator also comes through the firewall. Again that is part of the overall belt driven system as it sits. I would still recommend the tranny adapters as it will only make the space issue up front a little easier to deal with. (IMG:style_emoticons/default/idea.gif)
