Toyota Supra With Clear Intercooler Shows Cool Airflow In Action

[ad_1]

Consider yourself forewarned, as there is little science content coming your way. Do not be afraid, because it comes with the help of the Toyota Supra A80 which packs a large turbocharger. That’s usually a great formula for fun, especially when there’s a see-through intercooler mounted front and center.

That’s where science comes in, thanks distorted perception Youtube channel. The job of the intercooler is simple: it cools the air before it enters the engine. Why is that important? Cold air is denser, which means you put more into the engine. More air means more fuel, and it produces more horsepower. In naturally aspirated engines, intake air temperature is not a major issue so an intercooler is not required. But the compressed air coming from the turbocharger is hot – over 200 degrees Fahrenheit (93.3 Celsius) as seen from this Supra.

The process of cooling the air is also simple: push it through the cooling fins as you would a radiator. For this particular application, hot air from the turbo enters the passenger side tank from the intercooler and exits the driver side. It’s one thing to talk about the process, but this video features an intercooler with a clear acrylic tank, allowing us to see it with our own eyes.

At first glance, watching the air move seems like a rather boring experiment. Even with a smoke engine in the mix, it’s just air going in on one side and out on the other, right? With the help of high-speed cameras, we can see that this is not an instant process. The entire passenger side tank filled with smoke before we saw anything on the other side. We also noticed the difference in temperature between the tanks, highlighted by adding a small amount of water to wash off any residue from a clean tank. On the left, the tank immediately dries up. On the right, it took a while.

How much temperature difference are we talking about? The final process adds two probes to the tank, and with the boost pressure raised to close to 20 pounds, the air temperature reaches 204.6 degrees F (95.8 Celsius) entering the intercooler. However, on the other hand, it is only 73.6 F (23.1 C). That’s a 131 degree difference, and for this Toyota, it can definitely have an impact on power.

Unfortunately, the custom clear tank failed after going through that, but the point was definitely made. The intercooler is simple but effective enough to cool the air for high power cars. Thus ended the scientific experiment.
