Predator 212cc Cam & Head Gasket Upgrade Dyno Test ~ The Road To Horsepower Ep4

[@paulmccoy3785]

Awesome series. This is exactly the type of content I have been looking for. Keep up the good work. I'll be impatiently waiting for the next video.

[@mikesbarn1858]

Waiting for the next episode of this series is like waiting for the next episode of the Mandalorian. Very exciting.

[@chrisgunn325]

Lol, so true!!

[@shootermcgavin2819]

that series is so overrated. whats wrong with you people?

[@trailblazer8380]

This is the way

[@kalikiller1771]

@@shootermcgavin2819 it's cool people enjoy it and television is rather lackluster of late so a good show is like cold water in the desert

I have a huge respect for all you KZbin builders/makers out there you literally produce and market Hollywood quality content weekly without aides or other actors just you some friends and your garage all the while working your daily jobs and raising a family the majority of you.. it's pretty nuts honestly....you sir are an over achiever and have no gripe about a small issue with filming issues. Keep up the phenomenal job

[@2000r0283]

I don't even mess with small engines but as a drag racer and car person I love watching parts comparisons and dyno test.

[@KrimsonSpeed]

Man I literally spent hours upon hours throughout November/December doing research and building a Predator 212 for a big minibike race. 99% of info about these motors on the internet is subjective or a secret due to Kart racing teams running these motors competitively. Thanks for making these videos and keep up the good work!

[@HashAssett]

Because nobody actually knows what they're doing lol. Plus every track is different, no combination of parts ever works for every track.

[@GrantOakes]

I'M LOVING THESE DYNO VIDEOS! Please, keep them coming! I can't wait until you do the same thing with the Predator 670.

[@kevin-pk6hd]

Would love to see a best bang for the buck test..thinner gasket, diy head work, cheap clone carb etc. How a broke kid would build it. See how that stacks up to the $$$$ build

[@Stevop79400]

This round of videos has had great audio. The sound of the tools and voiceover were spot on.

[@SurlyMike]

Can't wait to see what some port work does to compliment the cam. It's very cool to see the air/fuel being shown in these last couple videos. You should get into that a bit more, showing jet changes and what not is required with each change to keep it in line. Very cool stuff!

[@westie4ageturbo.749]

As you show its not just peak numbers but area under the curve that improves It would be great to see side by side graphs or overlays Peak hp does not tell the whole story Great video mate!

[@RedBeardsGarage]

I plan on doing a lot more with this series over the next few months. We will be doing graph comparisons to show where you gain the power and all the info. Thanks for watching!

[@lawrencecoleman7850]

That's true but he does show the Dyno chart and I paused the video to see the gains at lower rpms and to see when the most HP started to ramp in but I'm sure that he is going to be doing alot more with these Dyno videos

[@NubsWithGuns]

@@lawrencecoleman7850 That's actually what a dyno is for, too many people forget that it's a tuning tool and there's more to those fancy numbers they care so much about. I love that Greg shows the graphs and all for us that's where you see if your work did what you were looking for.

[@lawrencecoleman7850]

Just picked up a 212, thought I was going to leave it stock until I found your channel. You earned a new sub here, thanks for spending my money red beard.

[@smsservicesall]

So the fake mikuni carb would have had it at 15+hp zz... I can't wait to see everything you have in store! I complained about you in the past in the comments section and I was wrong. You kick ass and I appreciate you.

where do you get the magnetic dipstick?

[@drewy3243]

Noticed Gopowersports sells a mechanical fuel injected carb. Curious to see if it would perform better at higher rpms than a regular carb.

[@donduck6195]

390 vs 420 vs 440 vs 459. All stock, then all with the same stage 1 kit. Let's see if the Honda is underpowered and if the duromax makes its claim

[@brian6029]

Loving all the dyno vids of you testing parts. Thanks for doing these. 😎👍👍

[@Armilite1]

Normally great videos! On these Dyno Test, You know all the Engine DATA, but most People don't it would be nice to have all the Engine Data, CC, CAM Spec, Valve Spring lbs, Valve Sizes used, Carb Size, Type of Air Filter used, Type of Exhaust used. A list of hp made at different rpm, other than just Max hp@rpm. These Honda/Clone Engines are being used on more Products every day. Go Carts, Off Road Karts, Snowmobiles, Snow Gliders, Air Boats, Mini Bikes, Hover Craft, Mud Boats, Part 103 Ultralight Airplanes, PPC, Kit Planes, Hover Craft, etc. Like for Airplane use they would be limited to Max 5500rpm for Durability and that's just for Takeoff 2-3min and then Power Reduced to 75% to 90% depending on Speed or GPH use. Part 103 Ultralights can only carry 5 Gallons. Part 103 and most Small Kitplanes use 26hp to 40hp Engines. The Lazair Ultralight first used (2) 5.5hp Chainsaw Engines then upgraded to used (2) Rotax 185 2 Strokes at 9.4hp@5000rpm each, then upgraded to (2) Solo 210 Engines 15hp each. All Planes have a Max Takeoff Weight (MTOW). A Good Power to Weight Ratio is 1kw for 10 kg to Fly Well. The Lazairs MTOW is 450 lbs = 204.1166 kg / 10 kg = 20.41166 kw needed to Fly Well = 27.37249 hp / 2 = 13.686 hp or 13.7hp needed for each Engine. Which these Honda/Clone 200/212 engines can make that hp@5000rpm. kzbin.info/www/bejne/joC0gIpofNambbM

[@1986alexpotter]

Awesome video, great to see the AF ratio on the graph! Keep up the great content.

[@3GingerCats]

That was good, but one thing I would like to have seen was the graph of the last one with the same carb against this run to see the changes in where the HP is with the different Camshafts. Also when you do the head, compare the two stock heads, against two ported heads (maybe just use a thick gasket to compensate for the lack of dish in the piston for the original style head)

[@CODOutdoors]

Another great video! The dyno don't lie, Playa!

[@DOITALLMFER]

I’m absolutely loving the series red beard!! I have one suggestion even though I’m sure you’d like as much content as possible, but I’m wondering if it would save you a ton of time if you just refer to your videos that shows the install part of the parts? I still watch it but I feel like it would give you way more time and dyno content if you just bang out the part install and show us the results. Probably be able to get through wayyyy more variations and combos that way we can get more dyno content. Thanks for the uploads brother !! Maybe run a poll to see what the viewers prefer? Just trying to make your life a little easier ! Less editing for stuff you’ve done 100 times and more time testing new combos! Also curious if you’ll ever run a subscriber dyno shootout? Awesome videos man. Loving the dyno content

[@terryj257]

That Ams Oil is awesome stuff. I swear I get an extra 200 rpm with it in my 2 stroke snowmobile. The exhaust pipes get a little sticky and messy but it's worth it.

[@drewy3243]

Love the video can't wait to see it fully built!

[@laverncarroll]

I really like the road to horsepower videos. Thanks a lot good work

[@fatbuddycat]

The small valve 14cc head is a popular budget option....giving up valve size vs compression. You could compare a ported 14cc to a ported stock valve on the same engine and I believe same head gasket.

[@lesheath6216]

Can't wait to see what the big blocks will make powerwise

[@tundra2000boy]

I'm iffy on the magnetic oil dipstick since the one I bought off Amazon and the magnetic came out of it and stuck to the connecting rod of my generator, got lucky that it didn't destroy anything

[@jthainz240]

Bought it off Amazon what did you expect

[@oif3vetk9]

This is a great series! Absolutely love it. Really hope the 459 predator gets thrown in the mix. Just started a Yamaha G2 project and am planning on dropping a 459 in it. (It has no engine so for my purposes I figure the 459 is the way to go.) For this year I plan on just running it stock but next winter tear it down and liven it up a little bit. Great series, keep up the fantastic work and have a wonderful day.

[@suarvemarv]

At this level i dont think you'll see real big gains from the head maybe 0.5-1hp but rockers heck yes! Do just the intake rocker dyno it, then do both, you'll see how little effect that extra lift has on the exhaust side.

[@luiemeza455]

I ordered the stage 2 kit that comes with all these parts from your affiliated links but I just noticed they come with 22lbs springs and you say 26lbs …. Do I need to reorder need 26lbs springs…….. and lastly do you think my 30series torque converter will be able to take it?

[@jamest.5001]

Id like to get a billet steel rod, with a pressurized oil system, forged piston, with oil squirter, and oil cooler, it should spin 10k rpm

[@jeffjohnson3912]

Guessing you’re already planning on it but I’d like to see what an EFI system will do, power wise, compared to a carb. Love this series!

[@chevyon37s]

Now with clearancing the crank, you removed a fair bit of material. How is the balance? Does it vibrate more? It looked like the exhaust was shaking like crazy at higher RPM on the dyno… but I realize that also may have been due to the dyno.

[@xbraekdownx]

Awesome series, should show dyno graph and numbers from starting point bone stock to what you have achieved!

[@190SkyTeam]

You didn't add assembly lube on the rod bearings??

[@RedBeardsGarage]

Yes I did. If you look you can see it dripping out after installing the rod cap.

[@milwaukeebrewcrew484]

Haha not here, fab on some oil and slap it together. Not everything needs to go by the book

[@shark11175]

This is FANTASTIC Red Beard! I have this exact setup on my Mini Bike and it is fast as hell

[@charlieward236]

It might be possible to remove the HP dip around 7000 RPM, by lengthening or shortening the intake tube between the carb and the head. It would be interesting to see how that will affect the HP output curve, and should be very easy and cheap to do. Since the cam was changed you changed the intake duration and resonance, and it normally means you also nee to change intake length to match the cam.

[@mattcangie]

@8:37 I agree modifying the crank is necessary but re-balancing, especially after that much grinding on one side should be considered. When you're digging for every last 1/10th hp, a balanced crank and blueprinted rotating mass assembly will unlock hidden gains. Also, is that dinky air filter a class limited size and/or manditory?

[@lloydchristmas8397]

i got a 356 cam in a 212...i cannot find a carb that works .....really enjoying the dyno runs

[@travishall3446]

In your experience what causes the drop or wave in power about about 6500? I would figure valve float, but I don't know anything about these engines. In a multi cylinder automotive engine, thats pretty much what it looks like when you loose valve stability.

[@ktownminibikes9553]

Is there any way you could dyno a 212 ghost, with the ghost "performance kit", compare the straight intake vs the 90 degree, and do a stock ghost carb vs mikuni, i think that would be interesting

[@markbinggeli3483]

Do you break in part & each time swap oil 😊 12:50 12:52 before the doing the Dino run?

[@markbinggeli3483]

Ok I finished the video and you answered my question

[@johnmartin560]

I hope you dyno test a 301 hemi Predator. I've had a lot of naysayers over the years tell me they're junk and not worth building. My Coleman CT200U-EX was a completely different bike going from a "stage 2" small block to a basically stock 301 with only a header & governor delete.

[@93xcr440]

You should check out David Vizard he explains rocker ratios and how they don't always do what they're supposed to each one will lift the valve off the seat at a different speed very good information to learn

[@crippleguy415]

Any excessive vibrations ? Mine shakes more than my old Norton motor . 😫...Did you have to rebalance the crankshaft ?

[@InterestingEndeavors]

I can't wait to see the porting numbers

[@r0ckworthy]

So I'm assuming the carb you're using for the dyno this time is your favorite from last time, the TM24 flat slide carb?

[@jeffrykopis5468]

RB, I was thinking, I'd rather have a cam with that same duration, but a lot less LOBE lift. I could regain the lost VALVE lift with 1.2 rockers, and not have to grind on the crank counterweight.

[@PittysGarage]

Would like to see a Paul’s kart cam on stronger springs with stock carb…. A lot of people watching are go kart racers an this gives us an idea of what hp our motors might be putting out…. But a lot of them have to run drilled stock carb style stuff.

[@hemeregildomarquez1174]

11:37 what’s that thing you start the motor with?…how and where can I get one?🤯🤯

[@mini0448]

Let's go love these comparison dyno vids

[@briantayes2418]

Does your dyno software allow you to overlay dyno runs? It is much easier to see the changes and where they happen in the rev range.

[@LowBoostFilms]

Awesome! Is this cam similar to “the racer” cam on Go Power Sports?

[@lizzard7473]

This is so cool. I mean it's just the best. Thank you so much for this.

[@bking4404]

Great job Redbeard really like this series I like to see you put your 224 stroker on their I built about the same motor so I'm anxious to see what kind of numbers that does that be great keep up the good work brother peace out

[@HappyHands.]

Something i missed in these 4 episodes.. did you change the Piston??? because i noticed it was flat. is that stock??? It's also odd that you have a cast valve cover when HF shows stamped valve covers on the predator 212

[@davidmorgan8612]

Love the series but please tell us what fuel you are using. Non ethanol? 87?91?93?100?

[@jamesmitchell2389]

yes, I too would like to know what fuel you are using. Inceased compression with the thinner head gasket need higher octane?

[@Dlokey4315]

Always a great show.

[@Iceheart721]

Just a few thoughts, are there cooling upgrades for these engines? With hp, comes heat. I see the new flywheel appears to have a slightly different fin design but is that enough? How long would one expect the lifespan to be without some sort of cooling upgrade? Which could be a neat addition to the series, upgrading the oiling system and adding cooling to it with external oil cooling to see how it effects overall engine temps. Have you considered non traditional engine choices for up coming builds? I know they can be harder to find bolt on parts for, but it would be very interesting to see. For instance I have a Rhino 450. They're slow but reliable, and I'll likely replace it with a maverick eventually. But without aftermarket support for real hp gains it would be very interesting to see how much improvement can be made from engines without thst support. Things like playing with different size carbs, porting and polishing, intake and exhaust upgrades. Mabey even a couple homemade turbo set ups. Things that can be done with any engine that just doesn't have the benefit of a huge following to bring parts and experience to the table. Also, this show is getting a very much too scripted vibe. Similar to the old spike tv shows. We all know damn well those e-clips turn into ballistic missles just by looking at them wrong. I don't know where you got those low tension stunt clips from, but it really takes away from the realism.

[@200shotramhemi4]

Great content! Excited for more

[@bigh3053]

Don't get me wrong, I love the content and the videos.Type of videos all of us want. I appreciate the effort. I just don't understand the high rpm pulls so quickly on break in oil. Normally two oil changes on break in oil are in order to remove assembly lube and tiny metal particles that come with these types of engines when new.

[@markyoung9964]

RBG does engine pulls off camera with the break in oil. Break can be as little 15 minutes- top engine builders with diamond hones and proper hone grits. That said, leak down testing/no oil residue inside the exhaust port verifies the rings have seated.

[@bigh3053]

@markyoung9964 I asked that very question, "Was a proper break in done before that high rpm pull? Am I missing something?" That being said, I would not do full rpm pulls on contaminated break in oil. I race prep Briggs Animal lo206 engines and have championship hardware to show. I have found the engines put out more power and last longer if the proper break in procedure is followed. Mostly decontamination the oil is the biggest deal. I also have a stage 4 kit on a predator hemi from NR racing with a 280 cam and 2.1 ratio rockers. I do not speak just to speak. I speak from experience.

[@jakedrew7365]

Good stuff thanks for doing this. Always look forward to the upcoming episodes. I'm sure you been asked to Dyno a stock ghost motor out the box and see.

[@chevyhp]

Awesome stuff man, this is next level stuff keep it up

[@chriss8206]

I was really curious about the lubrication of a lot of these predator motors and Honda engines at general oil thrower at the bottom of the connecting rod I made a clear side cover ran the motor and was surprised to see that the lubricant only flung around the gears the teeth themselves and would drip down on the connecting rod bearing and other parts after you shut it off So I took a file and made a very small flat portion on the oil thrower towards the front of the motor made a nightinday difference with the way the oil splashed around

[@khrisyeet8022]

At 12:17 or 12:18 what fell off the motor by the kill switch?

[@mackelby1]

can u do coils when u get done on maxing out this engine. im wanting to see if they make any differences.

[@bradenclifton45]

Im sorry but you should try a big filter with velocity stack! That little filter has to be hurting a little power! Love the series

[@cooperthomas5290]

[@JANNETTYRACING]

You are getting Valve float above 6600 rpm try stronger valve springs.

[@Ghostofurzikstan]

I’m building a big valve big cam 356 predator hemi with a non hemi head 212 with 1.2 ratio rockers I just can’t find the right pushrods

[@srcobra50]

Really enjoying these Dyno videos. Maybe a video on comparing to fact same mods on a 196 vs 212? Just to see the differences in power bands

[@CreeperOnYourHouse]

I wish that forged steel connecting rods were an option. Why not dyno the head gasket and the cam separately?

[@Jesus_Saves_J2415]

What if the engine is idling fine and revs up but no forward or reverse.. what could be the problem? Brakes aren't seized either

[@jeffrykopis5468]

RB, why does it matter which way the arrow on the piston is oriented to the rod? Is the pin offset?

[@Ratkill9000]

I'm curious if you took a stock 212 Hemi and just did ratio rockers, what those alone could achieve.

[@blakestonebustosrb]

Where's the link for the magnetized dip stick??

[@cliftonparker7817]

Looks like the valve springs are floating above 6000 Usually signs of too weak of a valve spring when they dip like that instead of a continuous arch Maybe stiffer spring or shim them if there’s enough room with out coil bind

[@cliftonparker7817]

The springs may have made the afr flutter to

[@carsonpeterman4564]

U should do an episode where you put timing to the moter and see the inprovements
