Clipping water pump impeller?

[SledPuller21]

Anyone have any pictures or advice as to how much to take off or to which fins? This is going on my puller, not worried about any long term or DD effects. Thanks.

IDK for sure, but when i did mine i start ed at the top of the fin, and tapered. I took off about 5/16 at the top and tapered to the end. It works, but i still had problems. I would do a bypass kit.Enterprise Engine, makes a nice kit worth the coin. They say that the CR can see PSI #s in the cooling system as high as 100 PSI, thats crazy, i would find you a cheap gauge and see what kind of psi your running after clipping the pump. 55psi is enough to push freeze plugs out. I think the bypass kit opens at 35psi

Im interested in this also.... i was about to start a thread like this but you beat me to it!

what about an electric pump?

 

[SMOKIN93]

That's just extra money that can be spent on something else, clipping the stock one is free and works good.

adding more electrical stuff just increases the chance of failure. thats if you wanna DD with it. theres nothing wrong with it for competition tho

 

[jeff115]

mine gets to about 60psi now i have 2 reliefs set a 50psi and 4 holes in my thermostat and i have not had one problem sled pullin

if its going on a puller only i would get a dr. performance electric pump and be done with it.

i did this to my old puller got the idea from bigbaddodge years ago i dont know if he still has the pics. you need to cut off two of the blades across from each other i used a dremel to do it. before i could blow the top off the coolant bottle free reving after clipping i could run over 5k with no issues it also eliminates blown freeze plugs

I just installed a Enterprise bypass kit $125 shipped to my door & I called it done. I never clipped my pump & have had zero problems.

All the way to the center? I'll give it a try. Most likley gonna make a bypass kit too.

What size holes.

yes, completely remove two blades

 

[zstroken]

I trimmed mine down. Just basically cut the fins down past inside the cones.

 

[cummins724]

Wouldn't that make it unbalanced?

 

[BgBlDodge]

If you do it on opposite sides of each other you shouldn't have a problem.

he said directly across from each other that should still keep it somewhat even
