larger h/e water pump E-force
Will adding a 20gpm pump to the e-force kit help temps? I'm wondering if the faster water flow wont give the h/e ample time to exchange heat.
This is the pump I'm considering

I am also considering RSD's Maggie cool-down kit behind the driver fog light opening.

How should I plumb both of these h/e? From the pump to the one away from the radiator first to keep most of the heat away from the engine then to the stock Edelbrock h/e?
Has anyone done the "daisy chain" h/e yet?

I would be curious on the outcome it you do this. I think the higher capacity will help more than the higher flow pump, but both would be good. Its hard to tell in the pic but the inlet/outlet on that tank look small to me.

Yea it is for a C5 but I e-mailed Steve @ RSD some pics and called him the other day. I think well try to work on a "kit" that'll fit better. His 10"X12"X4" H/E (with fan) is a little big i think. If I'm using it in conjunction with the stocker I think I can afford to go a little smaller.

Wasn't it Corvettes of Westchester that was working on a heat exchanger upgrade kit for the EForce? The key is getting a bigger/better h/e fitted. Better air flow through it helps big time too. Bigger pump won't do any good without h/e upgrades. I've heard that just adding a high flow pump actually makes the problem worse. Bigger coolant tank delays the hot temps, but once hot, you're right back where you started.
Seeing those big honkin' air/air coolers that the centri/turbo boys use, you'd think that a bigger air/water cooler wouldn't be that difficult. I'm actually adding a full size radiator with e-fans for the h/e on my Maggie blown truck project. It will have the 20gpm pump also. Wish my vette was that easy to upgrade.

We have done significant testing using larger pumps, and the simple answer is no.
Changing out the pump alone with more than likely hurt your temps. The E-force is already using the larger Bosch pump.
The cooling system is a fine balance of capacity, flow, and heat exchanger surface area. By speeding up the flow, you will lower the heat exchangers ability to pull the heat, by reducing the amount of time the coolant is in the heat exchanger. If you slow it down, the coolant over heats in the head unit.
If you plan on making a change, do it to the entire system. not just 1 or 2 parts. You could get away with a larger heat exchanger AND pump, but you would be better served doing the reservoir as well.
A while back there was a large write up about this very thing in the mustang world. It had quite a bit of good info in it. I would do a search for it.
HTH!
