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
My first thought was turbo, second was oiling.
@@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
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.
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.
I'm definitely excited to see you slap it on literally anything
Can’t wait to see the upgraded parts list for this engine. Looks like a cool engine. Can’t wait to see you build it and put it on Gravy Bones!
Pressurized oil is massive. Very interesting. Can't wait to see more inside this thing.
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.
Looks like they decided to step up there game on the predator big block 💪🏼
Can't wait for the parts list and build.!
I want to build something even more now. That is a pretty sweet set up for a usable bike or buggy
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...
I just did a governor bypass on mine and now I really love it
Can't wait to see what you can do with this motor!
Just bought one of these engines today.... destined for a small hobby tractor.
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 think I'm going to buy this for my atv snowblower build ,looks like a good engine
Awesome improvement
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.
If your pumped I'm pumped. LOL Waiting for the breakdown.
I got to say I am impressed
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.
Did you see the dyno Warped Perception built? That was pretty simple
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?
First I’ll take my wife shopping then I’ll buy the engine. This engine is perfect for my spider box yerfdog.
I can’t wait to see what these can do! I want this on my Coleman Uex
Gotta do a comparison between this and the duromax 440cc
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 🤙🏼
I had no idea about the oil system! Just saw it at harbor freight over the weekend
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.
I'm enjoying mine with avacado 👍🇺🇸. Thanks RB.
What an awesome giveaway that engine would make sitting on my go kart. 🙏🏻🙏🏻🙏🏻
Going on my next air trike!
Lots of potential
I put one of these in a 1968 Ski Alpine snowmobile. So far,so good.
Can you post a video?
Great video
Now I wanna see perf numbers (actually tested) between this and the 440 duromax!
Do a couple rips up your driveway with it stock,and then once built so we can see the difference,please.
Very nice!
I gotta get one. It’d look good on my buggy that I’m building.
Put that mother on the mb200-2🤔 love y’alls videos! Thanks
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
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 👍
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.
These engines have come a long way in quality
I think I want two.
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?
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
We need parts!
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 !
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
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
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.....
I would like to the same oil cooler and filter
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.
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.
I had a generac small block with an oil filter.
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!!!
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?
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!
YEAH BUDDY!
I hope I can get one…. Nice engine… pressureized oil system.. now I may just get one….
So do the 212 aftermarket parts fit? Or is GPS making new stuff for the 224 and 459’s?
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.. :>)
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
What torque converter set up do you recommend for this engine ? Not much info out . One guy guy says 40 series and another says you have to use the 780. Only upgrades will be bolt on for my 2 seater manco . Thanks love your videos !
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
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
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
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.
Need to see if I can mate one to my genset.
I would love to see a Harley type twin cylinder set up. More cc smaller cylinders
When will you be putting aftermarket parts on the engine
Seen this video a few times this part always makes me wonder 3:25
Headed to harbor freight now. BTW you mentioned in an earlier video about upgrading from mechanical disc to hyd . What was the video title if you dont mind
Gravy bones that bad boy
This is not the first one with a pressurized oil system. Zong shen made a gx390 clone that came in some generators/welders that had a full oil filter and a pressurized system.....we see them at the scrap yard from time to time and wore slap out. Does the 459 have a charging system ? The rocker style starter switch is awesome
Would you reccomend a high zinc oil to help on break in? Or just synthetic?
Do you recommend this engine for my mini dirt drag bike build? Looking to get fast without a ton of aftermarket’s
So Red Beard, I just bought one today. I’m going to run it on one of my race mowers. We can run up to 3650 in rpm’s before being teched out. We can not be over…
I see on the box it states a lower rpm from the factory. Tell me how do I tweak the governor to bring up the rpm’s? Thanks
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?
You should make a video of the go karts and utvs at rural king!
I'm curious if these would make a viable replacement engine for old garden tractors.
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
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.
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.
Could you compare this engine to a duromax 440 and Vegas carts 460, I’m wanting to put one in golf cart and just don’t know witch one to go with, I know the 460 is discontinued.
What's the Oil Pressure and can an Oil Cooler be Added. Is a 34mm Carb the Largest it can use? Total Weight would be nice.
Turbo!!!
What would you recommend for the go kart set up?
The mikuni will be fine. The intake stayed on two Inch Center to center mounting.
I have the same motor and I noticed the exhaust is bigger than a normal predator motor?
How well would this engine work in a garden tractor ???
Thanks
JP
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?
780 series would be your best bet
@@randallbaker9055 i installed a 420 on a club car carryall2 ,with a 4 inch lift and 22 inch tires, has plenty of power and torque. great combination!
@@DWinnie67 what cvt did you use
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.
Turbo is easy now
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
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
Is the governor removal the same as the 420 cc
Hey Redbeard will the 459 Predator motor fit on the Motovox mini-bike
I wonder how many psi the oil pump makes one and two that would make it way easier to install a turbo and or oil cooler adding even more to the longevity the only thing I don’t like about the hemi version is valve clearance because they’re at an angle but I guess you could fix that with a different piston but otherwise I totally agree with you Redbeard I just bought one myself and for that $50 savings bare minimum you could put a header carb upgrade or air filter upgrade one last thing kind of low compression Ratio in my opinion 8.8:1 but that would be pretty good for forced induction and as always great videos red beard personally my brother and I are going to build a mini truck go kart with a craftsman dump bed and craftsman hood then I’m going to fabricate a cab i’ve already got the frame built rear end suspension front end my hope is that we can do some mild off-roading even though for the time being it’s going to be two wheel drive but by the time I’m finished it will be four-wheel-drive
There's one of these on the open box shelf for $200 near me. Should I get it??
When are you going to do the update on the 459???
What's your opinion on using this motor as a John boat mud motor?
