I have not the slightest idea, Im just a pulley and fan belt man myself. Try posting a new question with that in the headline. Good luck [img]graemlins/waving.gif[/img]

Just based on what I've read here, the elec. water pumps are better suited for strip only.

But, like anything else, there's always a successs story to be found.

Yah I wonder what size radiator and water flow is typical for the electric pumper. It might be a case of lighter smaller radiators for the drags. I'd figure since I've got the direct drive fan and water pump I'd free up some hp.
Kinda pricey those pumps. My last look at them got the no way reaction.

I'm running a pulley and fan/pump (Stewart stage ii) as well, but I did look into the Stewart elc pump and I am quite impressed with it comparred to a lot of others out there. The good mechanical pumps put out the same or even more flow at top rpm but the nice thing about the electrics is the good flow at low rpm and idle. Stewart has a pretty good question and answer area online and they respond to questions quite fast as well. If I can find the (claimed) flow comparisons I will post them. Barry

I just found my reply from Stewart and they claim:
Their elec pump puts out 55 gpm which is equal to their mech pump at 2500 rpm
They said all things being the same and with stock pulleys the mech pump will put out
150 gpm @ 7000;
25 gpm @ 1500;
17 gpm @ 1000;
When I quizzed them about power to run the pumps they said your stock pump will use
7.2 hp pumping 100 gpm @ 6000 where as their mech. pump will use 2.9 hp.
I never did find out what their ele pump will use pumping 55 gpm but I guess that depends
on your charging/electrical system.
I think my neighbours kids car uses about 12 hp to run his STEREO system lol.
Hope this helps - Barry

You know what. I wonder about the life span of the pump for people who have to run a thermostat.

[novaderrik]

if you run an electric water pump, i don't see why you'd need a thermostat.. you could use an elecctric fan temp switch to turn on the water pump when it needs to be on.
