Sure flow mod on koralias?

[tkeracer619]

It has to do with a term I cannot place atm. The motor is not strong enough to turn the prop without causing it to fry. It would be similar to putting a kias 4cyl into a chevy pickup truck and trying to tow an oversized load. Sure it will get you from point a to b but how long do you have to floor it to get it up too highway speed? 10 minutes? During that time the motor is getting too hot and stressed, eventually it will let go. This is similar to what is going on inside a k4 when you do this. It can never get to full speed so the motor slips well beyond what it was designed for.... eventually burning up the motor.

... looks for EE text books.

If you have a koralia and want more flow, buy a $18 maxijet to use with the sureflow. It will last a lot longer.

i put a a maxijet magnet from a mj1200 into my k4 a piece of hard airline and a prop from a hobby shop and it seems to work ok only 2 months on it. does the larger magnet help the motor out at all. also i think a little less pitch on the prop will help extend the life but also cut down on the flow... but still way more then stock!

Just gotta wonder is it worth it. Why not just buy another pump. The pumps are so energy efficient to begin with. How much is the modification $20-30. Compared to buying another pump you might spend 2-3X that and you have an unmodified pump that is in good working order and under warrante, as soon as you modify the pump the warrante is out the door. You should get years out of the pumps instead of months. The modification was not made for the koralia. I have not looked at all the specs for the modification and what it was intended for. But if the motor size, energy consumption, impellar size or anything is different about the pumps- there is a chance that a modification will not be compatible. Especially if you start cutting the impellar to make it fit. The stress is different when you start modifying the mod. IMO just buy another koralia to suite your needs and take the guess work out of your pump possibly dying on you. IMO its not worth the hassle, stress, and guesswork. Also how much more are you really getting out of the pump.

Magnet does not matter, it will fry eventually. I ended up trimming the prop down to almost stock levels. The stock prop is designed to move water in a broad direction and has a lot of downfalls if you are trying to move a lot of water. As soon as you stick the big prop on it turns it into the same amount of flow as with a maxijet. A maxijet, sureflow mod, and suregrip costs less then a k4 with a sureflow mod and will last 10x longer.

If you want more flow, get a different pump. koralias are not meant to be driven harder then stock. I would not be surprised given the size of the stock magnet / motor assembly is already being overworked to get stock flow.

Hey guys,

I bought the Sure Fow Mod and then noticed that it's a counterclockwise rotating prop while the Koralia is a clockwise prop....So how exactly is everyone getting this to work????

Looks like the Koralia would have to run backwards to work...I got mine to work but its very hard to get started again (backwards)
