Predator 212 Hemi Vs Non Hemi – Which You Should Choose

Spread the love

The Predator 212 engine is a popular go-kart engine you can easily find in the market. Moreover, it is also used for other recreational vehicles, equipment, and tools. Very few know about the Predator 212 engine versions, predator 212 Hemi, and non hemi.

There are some differences between both of them. Do you want to know what will be the best choice for you from Predator 212 Hemi vs Non Hemi? The major difference is that the Hemi has 2 to 3% high engine speed and output because of the piston head design and hemispherical chamber. However, you can have the best modification options and part compatibility. You can apply modifications by using the kits for different stages like predator 212 hemi stage 1, 2,3, etc.

Do you want to know from predator 212 hemi vs non-hemi which is better? This article will discuss the predator 212 hemi vs non-hemi differences and their similarities.

Differences and Similarities Between the Hemi and non hemi

Here we will discuss some similarities and dissimilarities between Hemi and non-Hemi models.

Model Number

The key difference between both predator models is the engine model number. You can see the model number under the 212cc badge and in front of the recoil starter as the item. Did you not know the difference between the predator 212 hemi vs non-hemi part number (model number), don’t worry; below are the model number for hemi and non-hemi models.

  • The model number for Hemi is 60363
  • The model number for non-Hemi is 69730
  • In addition to Predator 212 Hemi or non-hemi, there is another model, Predator 212 non-hemi EPA, which is only usable in California. Its model number is 69727.


Apparently, both models have the same look. However, some visual differences also exist that will make the predator 212 hemi vs non-hemi identification quite easy for you, which are given below;

Valve Cover

The valve cover is the first visual difference between the two models. There is a different valve cover for both models, which you can easily distinguish. The valve cover for the Hemi model has a rectangular design and is matt in finish. And the Predator 212 non-hemi valve cover has a glossy finish and is octangle-shaped. On both models’ valve covers, you’ll notice the abbreviation of the overhead valve “OHV” embossed.

Air Filter Housing

The air filter housing is one more visible difference. You will see that the non-hemi model has a bit taller and curved air filter housing. And the air filter housing of the Hemi model is in a more squarish design and has less curvature at the back.

Chamber Design

Here is a comparison of the chamber design of the Predator 212cc Hemi vs non-hemi engine. The non-hemi has a flat chamber and a flathead piston design. And the Hemi model has an angled piston and hemispherical chamber.

During the combustion cycle, the Predator 212 Hemi head design helps it experience less energy and heat loss, which increases output and power.


Here is a comparison of the Hemi and non-hemi engine’s specifications. You can see from this comparison that, except for a few performance-related measures, which we’ll discuss in more detail later, they pretty much have the same specification. 


Here is a predator 212 hemi vs non-hemi performance comparison. As was previously mentioned, a hemispherical chamber design with inclined pistons usually permits less heat dissipation in the combustion chamber, which makes the combustion cycle more efficient. 

However, it must be acknowledged that the Predator 212 Hemi variant offers only a modest performance boost right out of the box. After testing both of these engines, it was found that the Hemi variant produced up to 0.3 horsepower more than the non-hemi version.

Peak Speed

The Predator 212 Hemi has a little greater enhanced output than the non-Hemi, which also provides it with a marginal peak speed advantage. Following the installation of both types of engines on a go-kart, I observed the following outcomes:

  • Non-Hemi’s Top Speed is 25 to 35 mph. 
  • Hemi’s Top Speed is 25 to 37 mph.

It turns out that the hemi variant may have a barely perceptible peak speed gain over the non-hemi version, amounting to 1 to 2 mph more. Be aware that the real top speed depends on several other parameters, like the weight of the go-kart, the size of the tires, the gear ratio, the aerodynamics, and more.

Weight and Size

The size and weight of both Predator 212 engine types are the same, notwithstanding the possibility of minor changes in performance and exterior characteristics. 

The mounting pattern dimensions for both engines are 6.40″x2.95″ to 3.17 (162 mm x 75.5 mm to 80.5 mm), and the overall dimensions of the engine are 15.4″x12.6″x13.6″. It also has the same weight, 17 kg (37.5 pounds).


All Predator 212 engine configurations are offered for purchase, although the non-hemi model seems the most popular. You can find them easily, which is why they are more popular. 

Also, keep in mind that you must make sure the Predator 212 engine you intend to purchase is an EPA-certified non-hemi variant (Item: 69727) if you live in California and plan to use it in a vehicle.


The Predator 212 non-hemi variant is the undisputed champion for engine upgrades because there are far more upgrades and modifications available for it. Although there are several mod kits (predator 212 Hemi upgrade kit, performance kit, etc.) and modifications for the Hemi engine, they are a little more difficult to find. 

The kind of adjustments is another crucial consideration. For instance, the 18 lbs., 22 lbs., and 26 lbs. valve spring upgrades are available on Predator Hemi engines. All those are present in the non-hemi, along with the 36 lb. valve spring. 

This also holds true for various additional internal and external components and adjustments. The non-hemi predator engine’s mod potential is far better in this regard.


We briefly described the comparison of both models (Predator 212 Hemi Vs non-Hemi). Choosing the Hemi or non-Hemi is based on what your requirements are. The Hemi model can be the best choice if you want faster engine speed. However, the non-hemi will be best for the mod potential and good part compatibility. Choose one that is appropriate for you. Good Luck!
