If you are done scrolling through the short comparison chart, let’s dive deeper into the comparison to see which one wins. 

Hx40 & Hx35 Housing Difference 

Housing is a casing that covers the turbochargers. Even though both Hx40 and 35 turbochargers usually come with cast iron or aluminum housing, there is a difference in the size.

Hx40 comes with adjustable housing, and so does the Hx35, but the 40 has a larger turbine wheel than the 35. Not only that, but the compressor wheel is also larger in Hx40. Due to the small components, the HX35 housing is more compact than the Hx40, which makes installation in tight spaces pretty easy.

On the other hand, the installation of the Hx40 is also effortless but not as much as the Hx35. If we put these two turbochargers on the same side, it would be hard for you to find any other turbochargers whose installation process is as easy as these two. 

Airflow Difference

Turbocharger airflow is what fills air into the engine so that it can deliver the power expected. The Hx35 turbocharger offers 0.46 Kps airflow, which is not a bad number at all. 0.46 kg/s is good enough to generate decent power. 

However, Hx40 comes with more, it offers 0.53 Kg/s airflow, and that makes it superior to 35 in terms of airflow. Due to the high airflow, obviously, Hx40 will have the engine deliver more power.

That being said, there are two disadvantages to that as well. Turbocharger that delivers higher airflow also consumes high fuel. Plus, they are usually louder compared to models with lower airflow. 

So it is a trade-off between power and cost. Most people are ready to deal with the cost and noise when they get the expected power. 

Size Difference 

Hx35 turbocharger is slightly small compared to the 40, which is why the 35 is easy to install, as we have mentioned before! The only difference is in length, the width and height are the same. Hx40 has a dimension of 231 x 250 x 169, whereas the 35 has a dimension of 224 x 250 x 169.

Power Difference 

As we have mentioned before, the Hx40 comes with a bigger turbine and compressor wheel, which is why it has a higher max boost pressure than the Hx35. And higher boost pressure means the turbocharger will make the engine yield high power.

And compared to the Hx40, the 35 comes with a smaller compressor and turbine wheel, which can’t produce airflow as much as the 40. And that results in less boost power. 

Downpipe Difference

Both of these turbochargers come with efficient downpipe wastegate, and the only difference is in size. The Hx40 turbocharger has a slightly bigger downpipe than the Hx35turbocharger. 

Difference In Suitability

Hx35 turbocharger is designed for light-duty vehicles like streetcars, minitrucks, and drag racing cars.

On the other hand, the 40 is for heavier vehicles like big trucks. The Hx40 can be used in off-roading vehicles as well. 

Hx35 Vs Hx40 Durability Difference 

This goes without saying that turbochargers need to be durable enough to withstand all the abuse. And both of these turbochargers got heavy-duty construction to deliver optimum durability. They are usually constructed with cast iron or aluminum material as they are high in strength and long-lasting. 

However, as Hx40 is designed for larger vehicles, it tends to be a little more rugged than the Hx35, a very slight difference. But if we look from a different point of view, both are perfect in their places. 

Hx35 is durable enough to take all the beating of medium-sized vehicles, and Hx40 can withstand the hard abuse of heavy vehicles. 

Hx35 Vs Hx40 Engine Capacity Difference 

In case you don’t know, lower engine capacity means low power, and vice versa. Having said that, the engine capacity of the Hx35 turbocharger is 5 – 6.5 liters, while the Hx40 comes with an engine capacity of 7 – 10 liter, which makes it outshines the Hx35 effortlessly.
