High Performance Water Pump ???

[Foggy]

Has anyone found a higher performance LS3 Water Pump for our SUV's ???
I have found a couple that are for the LS3 in a camaro/corvette, but those are
different than our Truck style set ups.

You don't need a HP pump. If you need cooling capacity you need a custom radiator. GM designs and builds radiators that are for HP installed....

Since you put a SC on it you need a higher capacity radiator, more rows etc....

i would just make sure what you have is working tip top, no leaks, no air trapped, no air getting back in. thicker core if you dont have the largest available is good advice. it gets worse the more you watch it lol. i think stock the engine will run anywhere from like 200-230 perfectly normally. heating up shouldnt be a concern but if it cant shed the heat afterwards then you need to be concerned

im still fighting with mine - but its pretty unconventional tho

A Tru-Cool oil and trans coolers will be a big help keeping the engine cool.

I've got the big Mishimoto Radiator. And I did the AC delco new water pump
when i did the SC last spring... I even tried a second different Mishi Radiator and
diff temp thermostats... I still get too hot while towing at highway speeds.
I have not added an additional trans cooler to the the HD extra cooler that's oem.
I did, however, put on the big deep trans pan with cooling fins...

I had been reading a lot of old threads about water pumps and had a "thought" that
maybe I got a bad pump or maybe could find a "better" pump, So was looking
for some options as it will be towing season in a couple of months..

IT's -20 wind chill here now... so some "overheating" sounds good BTW
