To me, a pressurized oil system means you actually have a place to tee off of to feed a small oil to a small turbo without having to run some sort of electric pump to feed it
@@bradmaas6875 could also probably run some kind of oil cooler(depending on how much pressure it makes since pressure drop could be an issue) but turbo would run a restricter anyway so that should be fine
The lower black cap that you called an oil drain is actually an oil filter. The GENERAC 459CC XT8000EFI ENGINE looks a lot like the new Predator 459. The replacement oil filter for the Generac is part# 10000027013.
Me personally, want to see an all out bolt on style build. Meaning no rod and flywheel. Just to see how much you can get from it before needing that expensive stage 2 kit. Turn it 5-5500k RPM, Carb, springs, header, possibly a shaved head? timing key etc etc. Basically all you could do before you gotta drop $500 on the stage 2 stuff. On another note, this beast still has less rated torque than the duro max 440 ~1.75. Maybe less of a big deal because RPM @ 2800 vs 3600 on duro. HP don't really matter to me so much as torque, proven by off road karts, torque is all that matters. But Duro is rated more HP there too by over 2. Redbeard you need a dyno at the house!! Give some legit before and after numbers. That dyno go power sports has can't cost that much can it?
operative word... RATED (by mfg) @ xx HP @ xxxx RPM's. some pppl have been knkown to ... stretch the truth a little to make a sale. I KNOW, that is unconscionable!!!! and u are offended... but it is the truth.
cast flywheel above governed speeds is taking a dangerous gamble. It might grenade or it might not. Losing the engine is one thing, but catching flywheel frag is a worst case scenario. It's not worth the risk. if you don't swap the rod and it lets go at 5k at least it will be contained.
@@angryroostercreations5194 People everywhere turn them to 6k no problems. The magnet is first to fling off and is actually well contained in the fan shroud. This is a myth that some how gained traction as being "oh so dangerous." When in reality, it is mildly threatening at best. I turn all my cast flywheels to 5500-6k and have yet to see a failure. Don't believe me? Plenty of old vehicles used cast iron flywheels and turned 6k rpm from factory. I assume then those were all on the ragged edge of exploding too? No built in safety factor?
The only single cylinder air cooled engines I know of that had oil pressure lubrication was certain Generac engines they also had oil filters and Kohler command engines, but this is awesome
I'm thinking one of the biggest things that needs is an upgraded oil screen, it looks like it has one on the side cover that unscrews but it would be good to see one that will pickup small carbon deposits not just large debris that the standard screen catches. I've seen many golf cart engines with oil screens that had ruined bearings because the oil change interval was too high and the screen didn't catch the smaller deposits.
Predator is definitely not the first ones to make a big block single pressure lubed engine. I have a generac 460cc single that is not only pressure lubed, but has a spin on oil filter as well, and it's from 2020
The rod is splashed lubed, the main bearings for the crankshaft are pressure lubed. Basically 1990s tech. Teledyne did that with their military engines(I have a 4a032), the crankshaft main bearings are pressure lubed, the rod is splash lubed
Cool how they packaged it bolting down to a piece of plywood, I bought a new Briggs for a lawn mower from northern tool and it had styrofoam packaging which was crushed into a million pieces til it looked like packing peanuts , luckily my engine was still ok but looking at the packaging you’d have thought they kicked it out the back of the truck while running 100 mph down the hiway 🤙🏼
Earlier was mentioned about turbo oiling. I also am interested, as well oil cooling and filtering. As you do your build if you could at least comment on the feasibility if not actually filter the oil, I would be interested. Your comments on oil starvation given pickup location and the gyrations the engine will go through on a personal mobility device (kart, bike) would be cool . Thanks very much Red Beard for all you do!
Oh, reading more I see that it already has a filter, very cool. Can a cooler be added and could you also comment on the possibility of mounting an alternator similar to what you did on the 640? You should also call HF to see if a modified twin is coming.....
so what youre saying is the only thing pressurized is the crank ends and rocker area? The most important is the rod being pressurized but its not, its still the old fashion oil splash lubed?
On the harbor freight website they do not mention the oil pressure lubrication, but it's on the box and you see the sensor and oil passage on the sump pan 👍
Oh thank the lord it is electric start! With the key switch missing I was concerned. Well, as long as I can do a different ignition or swap to key start on something I'll be a happy panda!
Those engines are made by Loncin and the generac 8500efi generator has the same engine I'm about positive, so you could throw EFI on the predator 459cc basically plug and play accept for the o2 sensor set up, idk if it would be tunable tho that's the question 🤔 but for sure worth looking into
I'd like to see you force feed oil, into that hole, that you pointed out and said that pressurized oil is sent, from the oil pump, through it. I'd like to see the oil draining from whatever gets pressurized oil. Like the camshaft. I didn't see if it has hydraulic lifters, like a Kohler Command. Just curious, if it does. What do you think about the block thickness?
So I have a question if you mention it in your next video about this motor. Alot of people use predator engines for Mud motors on boats. I'm curious if you could talk about the charging systems in these motors as it's something pretty important to us for our lights amd so on. I just need to know if it's worth buying and possibly saving some money before I go and get a Kohler with a 10amp charging system.
Looks like I know what engine I am using for the turbo cart build.. already working on a blow through carburetor for these carts. Billet from scratch carb design based on Holley modular architecture.
I’d love to see you guys get a dyno and have real number comparisons and how much each kit can add. I don’t know how much a small engine dyno would cost but with the variety of engines and different stages of build you have it would be very interesting
What size shaft is on here, I’m gonna buy one and put it in my spider box but I’m going to go with a clutch set up rather then torque converter cause I’m 13 and don’t have the money to buy the 190$ torque converter. I just need to know the diameter of the shaft so I can order a clutch for it
Definitely would like to see it stock in something but then I would be curious so see a couple bolt on's to see what it'll do. Predator is really stepping up the game!
Like the idea of more torque for say a small wood chipper - but leery about no bearings on the crank anymore maybe - on a little drum chipper these'd get beat up a bit? Can you have a good look at the bearing/ bushings during a teardown pls? Rest seems great.
Very nice and complete review thank you very much ! Just wonder if that can be a good plan to swap that engine on my 13 hp 45" troy bilt snow blower ? Thanks !
You have inspired me, gotta (save $$$) get me a tig machine, your delivery and explanations are perfect and I like how you say oyeell...that's awesome. Can't wait to follow this build.. :>)
I think it's definitely worth the extra because of the pressurized oil system but I think the dipper on the rod is a bad thing. I think it would aireate the oil which is a bad thing to do. I would hope the aftermarket 4od would take it off. I don't think you could just cu it off a stock rod because it would mess with the balance of the rod and piston. I think I will definitely have to go and pick one of these up now.
I got one for my go-kart it is stock ,, I hope it works for a long time & reliable most of all ,, ,, idea I would like to see two of those engines on a go-kart work side by side that be cool
That pressurized oil system is a game changer. WHEN will the STAGE 3/4/5 billet parts be available? Especially billet Rod, Flywheel, 1:3 roller rockers, larger valves, valve seats, bronze valve guides,and MOST of all, will you please build a bracket and put that 30 amp 670 alternator on it and ALSO that A300 supercharger, with that game changing HD FWD/Reverse gear box you had in another video with the HD 80 torque converter pulley. If you can get these parts made and this build achieved, I'll buy two of them myself, for my own Trailmaster karts! I can't wait!!! PLEASE!!!
Govenor removal and stage 1 kit. What type of cvt system to use and belt. Header as well? Also for an off-road go kart is this better than the tillotson built 223 that make 17hp?
Hmm, I need one of these for my goof cart... I'd say hop it up to the max. See how much power it can make with an ultimate build! Maybe a turbo build since you now have a way to feed it oil?
Im running this same motor bone stock, im using it as a mud motor for my aluminum boat. I noticed that when running at high speeds i have a constant blue flame coming form the exhaust.. Does this mean its running rich ? How can i fix it? Thank you for your time.
Do you have a video or segment on how you like to break in this or any other Predator engines? I just got the the 459cc, for a work vehicle. Any thoughts or direction would be appreciated
I have a 1961 Simplicity that has a 8HP Briggs on it and my 460 will probably find it way in there (probably going with a V_Twin so instead of trying its hardest to cut grass it will be a minni skider heck I have a plow/dozer blade for it
Ya could cut the cylinder off the block, and swap on a motorcycle jug and head! If you could aluminum weld, and access to a mill, just make a rod that fits the crank and piston, would be the simpler way to do it, especially if it has pressurized oiling, put about a 500cc jug on it, maybe 4valves! Probably get near 40 HP, if it will spin fast enough, because the head makes all the power, everything else just uses it!
You know what I would love to see done is put it in a little artic cat 120 I know that sounds lame but I really would like to see how my son has one and it's time to make it faster
Awesome. Been planning on buying a 420 to put in an old electric golf cart. This seems like a better buy for sure. What belt/clutch would work good with this and a gearbox for my application?
You should do a stock build and get test runs and build it and see what test runs are or just throw it on a frame you have really curious what it it's like stock vs fully built
Everything about this says to me they took the 420cc as a base, and improved it with this 459cc, aiming it specifically at fellas like us who hot rod them and throw em in go karts

My first thought was turbo, second was oiling.

oooo tiny choochoo noises.... im ok with that idea
Can also add an oil cooler 👍
HI, pressurized oil system means nothing if not getting to con. rod big end bearing. Please let me know. If this is the case with this engine.

Looks like they decided to step up there game on the predator big block 💪🏼
First I’ll take my wife shopping then I’ll buy the engine. This engine is perfect for my spider box yerfdog.
The only single cylinder air cooled engines I know of that had oil pressure lubrication was certain Generac engines they also had oil filters and Kohler command engines, but this is awesome
a lot of kawasaki single cylinders have pressure lube and spin on oil filter.
Do a couple rips up your driveway with it stock,and then once built so we can see the difference,please.

I had a 440cc duromax on an old dirty dog and was all proud of myself. Now this! I gotta go get one of these now...
Predator is definitely not the first ones to make a big block single pressure lubed engine. I have a generac 460cc single that is not only pressure lubed, but has a spin on oil filter as well, and it's from 2020
I'm definitely excited to see you slap it on literally anything
Pressurized oil is massive. Very interesting. Can't wait to see more inside this thing.
Now I wanna see perf numbers (actually tested) between this and the 440 duromax!
We have a 15 year old 27hp Kohler motor in craftsmen with a oil cooler and it runs amazing with that oil system and it running cooler.
If your pumped I'm pumped. LOL Waiting for the breakdown.
I put one of these in a 1968 Ski Alpine snowmobile. So far,so good.
Can you post a video?
I want to build something even more now. That is a pretty sweet set up for a usable bike or buggy
Just bought one of these engines today.... destined for a small hobby tractor.
Gotta do a comparison between this and the duromax 440cc
The rod is splashed lubed, the main bearings for the crankshaft are pressure lubed. Basically 1990s tech. Teledyne did that with their military engines(I have a 4a032), the crankshaft main bearings are pressure lubed, the rod is splash lubed
I just did a governor bypass on mine and now I really love it
What an awesome giveaway that engine would make sitting on my go kart. 🙏🏻🙏🏻🙏🏻
I think I'm going to buy this for my atv snowblower build ,looks like a good engine
These engines have come a long way in quality
Cool how they packaged it bolting down to a piece of plywood, I bought a new Briggs for a lawn mower from northern tool and it had styrofoam packaging which was crushed into a million pieces til it looked like packing peanuts , luckily my engine was still ok but looking at the packaging you’d have thought they kicked it out the back of the truck while running 100 mph down the hiway 🤙🏼

Can't wait to see what you can do with this motor!
Would you do a video of putting this motor in a golf cart in it's stock form? Would like to see how much better it runs vs the 420 in the golf cart.
That’s what I want to do is install one in a golf cart but not sure about the switch on the side and I would want a key switch I could mount up front
so what youre saying is the only thing pressurized is the crank ends and rocker area? The most important is the rod being pressurized but its not, its still the old fashion oil splash lubed?
Nice I’ve been waiting for u to do a vid on this engine. Much appreciated.
Really excited to see what is capable with this engine.
Seen this video a few times this part always makes me wonder 3:25
Can't wait for the parts list and build.!
I'd like to know how much of the engine gets pressurized oil? Is the crank drilled for pressure to the rod or is that why they used the dipper rod?
No the crank is not drilled. I've killed two of them because of oil starvation to the rod.
This engine is awesome the best one Ever built I hope you build this wild put in a big radical Cam in itWait for you to build this one
I got to say I am impressed
I had no idea about the oil system! Just saw it at harbor freight over the weekend
Put that mother on the mb200-2🤔 love y’alls videos! Thanks
Turbo is easy now
On the harbor freight website they do not mention the oil pressure lubrication, but it's on the box and you see the sensor and oil passage on the sump pan 👍
Oh thank the lord it is electric start! With the key switch missing I was concerned. Well, as long as I can do a different ignition or swap to key start on something I'll be a happy panda!
An oil pump just to lubricate the head? That's dope. Oil feel for turbo.
Those engines are made by Loncin and the generac 8500efi generator has the same engine I'm about positive, so you could throw EFI on the predator 459cc basically plug and play accept for the o2 sensor set up, idk if it would be tunable tho that's the question 🤔 but for sure worth looking into
A problem I see on the side case is a lack of a big roller bearing.
They don't have the bearings when they are pressurized oil system. 670cc is the same way.
I'd like to see you force feed oil, into that hole, that you pointed out and said that pressurized oil is sent, from the oil pump, through it. I'd like to see the oil draining from whatever gets pressurized oil. Like the camshaft. I didn't see if it has hydraulic lifters, like a Kohler Command. Just curious, if it does.

I can’t wait to see what these can do! I want this on my Coleman Uex
Awesome improvement
Shit now I have to upgrade my snowblower
Looks like I know what engine I am using for the turbo cart build.. already working on a blow through carburetor for these carts. Billet from scratch carb design based on Holley modular architecture.
We will play with that soon. Only problem is no billet flywheel is on the market as of right now.
I’d love to see you guys get a dyno and have real number comparisons and how much each kit can add. I don’t know how much a small engine dyno would cost but with the variety of engines and different stages of build you have it would be very interesting
I'm enjoying mine with avacado 👍🇺🇸. Thanks RB.
I have the same motor and I noticed the exhaust is bigger than a normal predator motor?
I would love to see a Harley type twin cylinder set up. More cc smaller cylinders
So do the 212 aftermarket parts fit? Or is GPS making new stuff for the 224 and 459’s?
What size shaft is on here, I’m gonna buy one and put it in my spider box but I’m going to go with a clutch set up rather then torque converter cause I’m 13 and don’t have the money to buy the 190$ torque converter. I just need to know the diameter of the shaft so I can order a clutch for it
Pressurized oil system means time for a turbo kit
Definitely would like to see it stock in something but then I would be curious so see a couple bolt on's to see what it'll do. Predator is really stepping up the game!
yeah doing the testing in steps would be really neat. do a stock 420, then this stock, then this with various mods, then with all the goodies
I think that alot. Wish they would do a comparison of out the box, no governor, then stages.
Like the idea of more torque for say a small wood chipper - but leery about no bearings on the crank anymore maybe - on a little drum chipper these'd get beat up a bit? Can you have a good look at the bearing/ bushings during a teardown pls? Rest seems great.

Modern oils have anti foam agents, as long as the oil is not hugely old it should be okay
When are you going to do the update on the 459???
Lots of potential
When will you be putting aftermarket parts on the engine
Golly mister, you're really strong
Your making me blush lol
I'm interested in not only building a crusty scab outta a Schwinn but, also a huffy WCC bike

Ok, now pull the governor and rev the Red Beard out of it!
I hope I can get one…. Nice engine… pressureized oil system.. now I may just get one….
I gotta get one. It’d look good on my buggy that I’m building.
Going on my next air trike!
This should bolt right up to a Coleman bike 😊
I see a bypass oiling system, a dip and slip rod and no ball bearins on the crank.
That style oil pressure switch is an on/off type not a variable. Also the black "drain" is actually an oil filter.
Govenor removal and stage 1 kit. What type of cvt system to use and belt. Header as well? Also for an off-road go kart is this better than the tillotson built 223 that make 17hp?
The better low end torque will show off-road with the added displacement.
Hmm, I need one of these for my goof cart...
I'd say hop it up to the max. See how much power it can make with an ultimate build! Maybe a turbo build since you now have a way to feed it oil?
Great video
