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.

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

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

[@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

[@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.

[@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.

[@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.

[@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.

[@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

Best video series I’ve seen in a long time! Awesome to see the numbers and see what parts actually do. And your knowledge in small engines is much appreciated as the internet can be misleading for us beginners!

[@goodguy...badrep.]

Can't wait to build my 1st Mega Moto 212 (just bought last week), your videos are fantastic. Entertaining and educational!

[@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

[@kenjohnson5498]

You might get a few more horse power if you stick a RBG sticker or two on that engine just saying.

[@markyoung9964]

I'm going to put a RBG on my forehead and run up the stairs-without the sticker I passed out. I'll keep you updated

[@drewy3243]

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

[@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!

[@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.

[@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)

[@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.

[@montanasoftware5954]

I'm also loving these dyno vids. Can't wait to see the V-Twin mods and results.

[@jameshleba8463]

[@davekulman8195]

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

[@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.

[@davidholcomb9961]

Yeah, this is fkg cool stuff! I used to love building v-8 engines, but i have to say, this is just as enjoyable just on a smaller scale. I wonder if it would be possible to come up with some videos of some epic fails? Like showing just how bad a factory flywheel explodes on the dyno? It would definitely make someone think twice before taking the governor off a stock motor! Yeah, that probably won't happen but i had to ask! Also the big block motors are going to really get my attention because i want to put together a bike with one, albeit stock, just for the torque to climb just about anything! I don't need to go fast anymore, i just want to be able to to get to those far away hunting spots!

[@speedyme200]

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.

[@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.

[@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

[@CODOutdoors]

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

[@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

[@brian6029]

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

[@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.

[@rocknrye9273]

According to GPS, I should be pushing 15hp lol. So you're trying to tell me I'm only pushing around 11hp? Lol nah, no way. Doesn't feel like 11hp, feels more than that. I have all this on my stand up scooter. If you want to check it out, it's on my channel if you're interested. It's 1 of a kind 😁 I only plan to make it more powerful.

[@carsonpeterman4564]

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

[@RedBeardsGarage]

The cam we are using is for the timing the billet flywheel has. We do have another cam to use later where we do have to adjust timing.

[@rocknrye9273]

Dam! Kind of disappointed lol. This whole time I thought I was pushing 15hp when in reality it's probably more like 12hp with the clone Kuni. Why on earth would GPS lie about their #s like that? They must have cheated their dyno #s just for sales. 😠.

[@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.

[@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

[@38possum]

Can anybody tell me if a predator 212 double magnet flywheel for a set of dual charging coils will fit and work on a tillotson 212? Gopowersports say they can't get the fly wheel that I need and that I would have to buy a whole new motor with electric start. If not I'll just junk the $400 tillotson and buy a predator. They don't explain this during time purchase, or have explanations on their web site that the motor flywheels on certain motors do not have magnets to run a head light. Looks as though I'll have to spend another $1200 just to have a head light.

[@evil_me]

I'd like to see different intake lengths tested, there has to be a different as the math suggests a different power band

[@RedBeardsGarage]

We have that video planned sir! Thanks for watching.

[@crippleguy415]

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

[@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

[@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.

[@lloydchristmas8397]

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

[@shrugger1]

[@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.

[@donniecole3472]

Looking 4 hp and torque suitable for micro light aircraft 670 / 990 cc that is outside of your normal.

[@jamest.5001]

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

[@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

[@lylehausser]

Use normal Motor oil when installing the pistons not Assembly lube, assembly lube is to thick and can glaze the rings and cylinder wall

[@xbraekdownx]

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

[@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.

[@Self.reliant]

Once you do the final build up with max HP you should do dyno runs with differant weight oils would be cool to see how much HP is lost by thick oil

[@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.

[@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.

[@albertjenkins8121]

OK I like all that now let's see one that's built like that and port match everything intake an exhaust wise an see what we get see if it helps throttle response an bottom end torque wise and be another series part to do too

[@igokarts4510]

Would like to see a Briggs or even a GC190 on the dyno

[@CreeperOnYourHouse]

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

[@seanb250]

What are the valve sizes in this? .265 lift might be velocity choke at the seat.

[@pullstartpatriot]

Local engine builders are going back and forth about engine oil weight and synthetic can change hp. 0wt 30wt 10-30wt etc. One guy says 0wt oil makes more HP cause dipper goes through it easier. Would be a good dyno video.

[@Stevop79400]

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

[@JANNETTYRACING]

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

[@brianhbinesh]

Need to add in costs to each of these upgrades. Price per HP gain per part.

[@the_LuckyPenny]

Video Idea: could you dyno and tutorial how to modify a small diesel engine for more performance? I see a lot of small diesel engines out of china designed for generators, irrigation pumps, ect and it would be interesting to see what power can be had from these.
