Why does exhaust shoot flames

It works by burning fuel after the engine, but still, before it gets to the turbo. This system will keep the turbo in action even when there are not enough exhaust gasses. However, a notable side effect is that it can create impressive flames. This method requires a lot of knowledge and equipment. It includes remapping the programming of your engine control unit ECU.

However, the skill level necessary for this modification means it is not feasible for noobies. In essence, the idea behind this reprogramming is to make your car keep the fuel going with a closed throttle. That means that fuel will go through the engine and out into the exhaust as unburnt fuel. The heat of the exhaust can light the fuel resulting in flames.

No matter which of these methods you go with, remember to be safe at all times. Tuning your car like this can be dangerous, and it might cause injury or material damage. Make sure to understand how each part operates and avoid any unnecessary risks. For example, make sure spectators are at least 30 feet away, especially during the testing phases. These flames can be really hot, and any leakage might lead to serious damage. The Vehicle Lab is reader-supported.
