Good to know. You had me worried there for a bit thinking that you ate LBZ pumps as well. I've run mine a fair bit so far and plenty (to much) RPM as well and it's still together.
I'm a bit concerned about localized hot spots due to decreased coolant flow of an electric. Maybe a non issue, but so long as the LBZ pump works I'm happy with it.
If we spin this one off we'll know it's pressure related. If not then it's inertial which is my theory.
Are you going to have a spare on hand for the DPC?
Murphy's Law: If you bring a spare, you won't need it, if you don't have a spare........
And good luck to you in the challenge (You were one of my three votes).
After seeing a truck with an electric on it, I don't think flow would be an issue. That sucker would push coolant past the t-stats it had so much flow. On the other hand I prefer a mechanical pump for a daily driver over an electric.
Probably 2 spare LBZ pumps plus at least one LB7 pump and cover.
Thanks for the vote!
once i drilled my t-stats and put in the 32 lb cap, I didnt have any flow issues with my Stewart pump. Like I said, I don't even turn my fans on anymore on test runs....If I was hot lapping...that's another story.
what did you have for flow issues prior to that?
when I get a chance i will try and take pics of my setup . its the same as what Dustin from DA did .
on WOT runs it would pressurize and blow out the overflow on my tank. I was romping on it pretty hard to get some decent logs. I'll post pictures of my t-stats in a bit. I run the bypass out of the bottom of the t-stat housing still too, and the heater core is still being used as bypass. That's going to change soon though, as my ducting is gone, AC gone, and heater controls are gone.
Edt: orginal cap was 16lbs

My tstat frames are all that remain on mine. We gutted both of them. No issues keeping cool, even repeated dyno runs.
maybe thats what is going on with mine! i thought i might have pushed a cup but maybe i just need to try a cap rated for more than 16 lbs...
i went thru 2 lb7 pumps last year and the third one i have in there now is welded both sides and havent had issues yet. i have a welded LBZ sitting here that im going to throw in next if i have issues.
That would be LB7 pump AND cover. Only for the event that my LBZ pump fails catastrophically in that the cover is damaged as I only have the one LBZ/LB7 customized cover.
OK after further reflection I came out of the fog and decided that I would simply bring a second LBZ necked down cover and skip the LB7 pumps altogether.
So what is the max power a stock LB7 pump can take for any amount of time? Has there been a fix for this yet.

Its more of the sudden change in rpms that will spin them off. So far my water pumps have not had a single failure.
I wish there was a belt driven option that would fit where the vacuum pump is, or behind the fan.
