In this video we test out the newest engine in the Harbor Freight Predator lineup, the Predator 224! These claim 6.6 hp and 10lbft of torque, and we wanted to do some real world tests to see how it compares to a stock Predator 212. We first do some spec comparisons, take a look inside, then mount each engine to the same Rascal minibike frame to do some test. We did a 260 ft drag race and a top speed run. We made 3 attempts for each and averaged them out to find the average 260ft race time and top speed. The results are pretty interesting!

So so, if you haven't heard, there's a new character in the harbor freight cinematic universe, the predator 224, we picked one up a couple days ago. These only came out three or four days ago, as of today so definitely brand spanking new and we're going to compare it to the predator 212, because there's been a lot of talk about the 224 on the forums and the facebook groups, some people like it, some People think it's not worth the price increase, so we're going to kind of do some real world testing and see what the advantages are to maybe picking this over the 212.. In terms of where the predator 224 falls in the harbor freight lineup, it's between the 212 and 301, it's basically a stroked predator, but as you'll see later we're going to get into these and kind of look at the differences and point you guys some resources for Some more in-depth uh measurements and specs, and things like that. So what we're going to do to test these is we're going to mount each of them in their stock configuration to our gopowersports rascal minibike same gearing and everything and we're going to do some tests average them all out and kind of just get the numbers and Look and see if it is worth it to pick this over this first we're going to compare the specifications between these two engines gone are the days of the 99 coupon for these 212s.

Now it's either gon na cost, you 129 or 149 for a 212.. The 224 costs 189 dollars, so that's a 40 40 increase and we're here to find out if that 40 is worth it. So, first of all the horsepower numbers - the 212 is rated at 6.5 horsepower and the 224 is only rated at 6.6, which is a very small increase, but the main increase comes in torque. The 212 is rated for maximum torque of 8.1 foot-pounds at 2500 rpm, while the 224 is rated at 10.23 foot-pounds at 2600 rpm.

So you know that's a two-pound foot increase when you're only making eight pound-feet. So that's a 25 increase which is actually pretty great um. Another thing is the maximum rpm rating, which i mean i guess we're all going to exceed, but for the 212 it is 3600 rpm and for the 224 is 3750 rpm. So there's a little bit of increase there.

Just for its rating, which you know, is a good sign, so the main difference in this engine is that the block is pretty much exactly the same. The difference is that the 224 has a longer stroke, so the bore on both of these is 70 millimeters, but the stroke on the 212 is 55 millimeters, while the stroke on the 224 is 58 millimeters. The main difference between these two engines is in the stroke, so the blocks on these two engines are pretty similar. It is noted that the 224 has a reinforced block, so we're going to go through it show the block see what's different and reinforced about it.

The bore on these two engines is both 70 millimeters, so the size of your piston is going to be the same, but the strokes are different, so the 212 has a 55 millimeter stroke and the 224 has a 58 millimeter stroke, so you're getting that extra stroke. For that extra 40 dollars, as well as a reinforced block, so stroker kits, can cost anywhere from like 100 to 180 dollars so for 40 dollars. If you're getting basically a stroker kit, we're gon na have to see if this thing's worth it all right enough talk. Let's open these things up, you all have seen a 212 before i'm pretty sure, but we'll unbox it anyways shiny.
It looks like we have a hemi. Actually, so that's pretty cool all right moment. We've all been waiting for the 224 christmas, so it comes with a little owner's manual safety instructions and it looks like you get some gasket and some carb jets here. So that's pretty neat uh.

The stock 212 did not come with that all right. Let's see what we got all right time to pull the bag off of this thing, wow cat's out of the bag. Everyone knows the red that adds power, the red paint, so it definitely looks nicer. This definitely looks like it's a higher performance version of that and it's not just the red paint.

You know it definitely looks cooler and it even comes with this little funnel, that's cool. So the only modifications we'll be doing to these two engines is that we're going to be removing the governor since that's what everyone does anyway, i mean that's pretty safe to do. We don't want to touch the carbs or the exhaust on these engines because if we start changing carbs and we got to tune the jets and have everything perfect and we don't want to introduce more variables, we want to just make this a very straightforward test. Show you what the stock does against stock, so, first we're going to take the gas inks off of these that'll kind of show us some of the block reinforcements and then we'll break open the side case and remove the governor all right.

There goes the gas tank, so normal predator looks as all of them do we're going to remove the governor arm first. So this will slide now we can move this around and get it out of the way of the governor gear. There we go so just a normal stock, predator everything's great, and we just need to get this uh governor gear out and pull the governor arm out same thing on this one: we're going to take the gas tank off first and here you can see some of The reinforcements on this block kind of similar to what tilletson has so it's kind of cool uh. You can definitely tell they put a little more thought into the design here.

Rubber pull handle instead of plastic, and it's got this stopper. It's got a bigger, uh, pull cover seems a little beefier. They have these like cable ties right here, kind of nice, same output, shaft and everything. So we've got to take the governor out on this one too, and then we'll compare the two going for nascar speed.

Here the case so right off the bat, i know one of the differences - that's going to be kind of a negative about this engine plastic cam gear. But if you are building it you're going to be replacing that. So you have to judge how much that really matters to you. Now that the engines are apart, we can see the differences between them.
I mean, like we said before we have this plastic cam gear, but if you're planning on upgrading your cam, you know doesn't really matter so this block is definitely reinforced. You can see at the top here. We have reinforcements there's a lot more little ribs. I guess that keep it reinforced, you know the bottom has them the sides have them the top.

Has it so it does look like a stronger block other than that. You know it's pretty pretty similar we're setting up our top throttle plate right now. This is from go power, sports and as well as the bike we're gon na put this on. It's also from go powersports.

So if you see anything, you like make sure to check out the links in the description, but once this is wrapped up, we can get to installing it on the mini bike. So we got our 10 w30 we'll fill these guys up break them in a little bit change the oil. Just to you know normal operation. All right.

We got the 212 stock on there all right, so we're gon na do three little drag race passes, ready, yep, ready. So now it's time for the top speed test. I'm going to have my phone screen recording the speedometer app in my pocket and we'll see how fast this thing can go. So it has stock valve springs and stock everything else, so it shouldn't be too fast, but we'll see what it does all right.

What's your impressions yeah, i mean you know, honestly, we we do a lot of really built engines, but i forgot how fun just having a you know pretty much stock. Predator. Has i mean just with the governor removed this thing's already a blast, i mean just with uh, you know some 18-pound valve springs and a new stage, one kit for the carb. I mean this thing's, actually a ripper, it's pretty fast.

The top speeds we're hitting. Were you know around like 40 miles an hour, so that's actually a lot better than i was expecting. So what also helps is that this rascal frame is really light. So you know it's pretty nimble, it goes pretty fast, it speeds up or it's got some good acceleration, so the 212 did great now it's time for the 224., so we got the 224 on here.

It looks really cool actually with the red and here's. Our first start, first time ever starting at 224. So, let's see if it's different, i guess i don't know a little choke. Like your predator, i don't know all right now, it's time for the same test for with the 224., all right now, it's time to test the top speed on the 224.

So after driving the rascal with the 224 on it, i got ta say i'm actually pretty impressed with this little motor. You know it's only 12 cc's bigger than the 212, but i actually did feel more torque and it kind of you know the engine dumped harder. It pushed harder we accelerated faster, i feel like it might even have had a little bit more top speed because it had some more torque, but i'm surprised i actually felt the difference. So it's pretty great, we'll have to see what the drag times are and we'll get some comparison.
So we got all our numbers crunched. We got everything recorded so now we can really compare the 212 and 224 so we're going to start with the drag race. It was a 260 foot, drag race which allowed us to get some pretty good speed going and the average time for the drag race for the 212 we did. Three runs was 7.71 seconds, while the average time for the 224 was a was 7.35 seconds which, and that is a 4.7 increase for the 224, which is actually pretty good.

You know just stock motor versus stock motor so for the top speed the for the 212. Our fastest top speed was 40 miles an hour with an average of 39.3 miles an hour for three runs, and for the 224, our fastest time was a 42 mile an hour run with an average of 40.3 miles an hour. So our best top speed was two miles an hour higher. You know not a lot, but for both of them had stock valve springs and everything.

You know, that's a that's a pretty good difference, so you know all in all. It did. The 224 definitely felt faster and i think the numbers show that it is faster. You know a five percent increase in that little drag race, that's pretty good and um.

You know when you start upgrading it. I'm sure you'll see even more of a difference. So now that we've got all the results back, we can start talking about some of the pros and cons for each engine for the 212. Some of the pros are the price it's 149 normally 129 on sale, so it's pretty affordable and you can buy one or two of them to stock up and keep for later builds.

Another pro is how long they've been out. Everyone already knows how reliable they are. How to build them get power out of them, so all that information is readily available. So that's pretty nice that there's that support there.

The third is that it has a metal cam gear, which is definitely going to add to that reliability. Factor for the cons is, if you did want to do, a stroker you'd have to buy the kit crank and everything so you'd be looking at about 100 or more dollars there. So it's a little more expensive to get this to where the 224 is and then another con is just you don't have the reinforced block, i'm not sure how much matters to you, depending on how much you're going to build it, but there's something to take into Consideration now for the 224, the pros are that it does have the reinforced new car block, which is really nice uh. You can tell they paid a little more attention to detail.

There's some nicer components on here. The pull start is nicer. Some of the wiring is nicer, which is something that's good to see. Another pro is that stroker crank.

You do get that extra 58 millimeters of stroke there, which is pretty nice, that it comes with that stock and the main cons for the 224 is just the price, and we still don't know how reliable it is. It hasn't been out long enough for people to give it some thorough testing. The main one is just that plastic cam gear, but if you're swapping it out, it might not be that much of a con to you, but you'll just have to kind of weigh what matters to you most. So that's all stuff to keep in mind, and hopefully these results can give you an idea of.
If you do want to run this on your bike or not or if you just want to stick with your 212s, so hope you guys enjoyed the video, give it a like or a comment. If you have other suggestions for us to test like, if you want us to build these engines, throw in some more engines in the mix, maybe we could even do some dyno tests uh make sure to check out the links in the description for the go.
