Today we experiment with a Harbor Freight Predator 420cc Engine. We show how to install an oil filter, oil cooler, and oil pump. We saw 30-40 degrees difference on the temp of the oil. With the added filtered oil this can extend the life of your go kart or mini bike engine and help make more power. We will be putting this on a 150cc go kart. Check the links out below.

Hi Red!: Thank you for your great videos + dedicated work on these small engines with a lot of potential to improve basic factory features; >How about installing the cooled + filtered oil (At least, part of it..), thru the valve cover to do perform a couple functions: >Lube + cool the valve train. >Cool the head itself *The rest of the cooled + filtered oil, to be returned thru the governor hole, thru a copper or brass tubing (Could even add a small nozzle..), to squirt oil to the mechanical moving parts, probably including the piston skirt iself + cylinder wall. *I'd also keep in mind the positive pressure built inside crank case to partially help the above circuit. >Bottom line is a cooler working engine should be a longer lasting one. Of course the oil pump itself should be strong enough to fully keep moving the cooled + filterd oil, and overcome the crank case pressure.. (Just my two cents)😢

For most inferred temp guns, you have to hold the gun 1-3 inches away from what ever you are measuring for the most accurate results. I have to use them in the oil refinery I work at, and it does make difference between holding them a foot away and an inch away from whatever it is you’re temp checking. Awesome video once again👌🏼👍🏼👍🏼👍🏼

@ryans750 3 жыл бұрын

Good job with that setup. If nothing else you have the ability to have a pre/post oiler for those all-day hoon sessions. I think the cases being the same temp on both engines is a result of them being designed as a heat sink from the factory and wicking heat from the cylinder. I bet if you got a temp probe you'd prove yourself right on the lower oil temp, which is the more important factor and might let you run a lighter weight oil and give you a little more power. Also if there was a way to dump the return oil out on the exhaust side of the head but still flow back to the sump quick enough, I bet you'd also pick up some power there too. A piston squirter on the return might also do the same.

@FPVSlacker 3 жыл бұрын

Instead of the oil cooler you could also have an external oil tank. This would increase the total volume and heat capacity of the oil.

@olsonspeed 8 ай бұрын

Is there enough space in the crankcase to run a loop of copper connected to an external radiator? I very much am interested in trying a liquid cooler or oil cooler on a 224, I have Honda Odyssey 250 that was modified with a liquid cooled head, it worked very well on convection flow.

I'm thinking about doing this for my 459cc predator generator and was wondering if the pump has held up well. It doesn't need to move a huge amount of oil but it's a gas/diesel pump, not designed for thicker and hot oil. The good part is that if it stops working the engine would just be back to operating like it was, pretty safe! I really appreciate this video!

I Pump FRESH WATER 💧 through this one and it heats water up in my water heater . It curculates water 💧 in my tank heating up my water tank , for hot 🔥 water to use for bathing or washing dishes or washing machine for clean clothes , i also use my generator to charge 3 AGM Battrys 150 amp hour battrys giving me 450 amp hours of DC current at 12 volts ⚡️ DC for my 3000 watt ac inverter. I controll everything with a marine generator controller.

Old video but I watched it and wondered if you could use the oil level wiring fitting as the return hole and make it more of an oil squirter system aimed at the bottom of the piston. would probably require a higher pressure pump

It's definitely a good idea to have the oil filter I did the same idea on my off-road tractor it had the 440 Duramax I use the drain plug for the pickup I didn't buy that nice pin I just drilled the hole at the middle of the tube to it and then head of it going through the pump through a radiator and then I went back into the valve cover it worked all right it's just over time because I had no filter everyone the pump
