Turbo Diesel Exhaust System - is for me a low-end torque and power to lose?

Myth No. 1 - If I have a 4 "turbo back exhaust I'm going to miss all of my low-end torque.

This is one of the topics of questions we receive almost daily. It takes different forms:
- I read the internet forums that you will lose all your energy level when you install a 4 "turbo back exhaust.
- My friend installed one on his truck exhaust and now is not the same power they have to take off.
- A diesel engine needs back pressure, and when you open the exhaust gas is toohurt my engine.
- A diesel engine needs back pressure, and if I lose the opening of the exhaust gases could.

Exhaust System

Due to the relatively low cost of a turbo-back exhaust, and the amount of diesel owners who are looking a bit 'more power, this is a very popular theme. First, it has a turbocharged diesel engine is not as much as pounds of pressure to perform after the perfect turbo. Indeed, less restriction after the turbo, the better. You have to understand that between theDrain valve on the head and the entrance to the turbo-pressure is usually at least if not more engine thrust at all times. Each counter-pressure for the proper functioning of the engine before the turbo, the estimated time. The pressure on the discharge side of the turbo exhaust gas temps just above. If we want to install

four or five inch turbo exhaust system, we see different things. First, usually a sharp drop in exhaust temperatures. A100-300 degrees or more drops are not uncommon. Second, an increase in fuel consumption. If the engine does not need to push the exhaust gas flowing from the exhaust system (in the first article we learned that an engine is nothing more than an air pump), it is with this performance, in order to fly and more power to the ground. And thirdly, we used to see somewhere between 15-30 rear wheel horsepower increase to the test when upgrading from a completely stockDrain.

And what about the internet forums, your partner, or even that you have noticed fewer power line after the installation of a diesel engine, high flow exhaust system? Well, you're crazy and your friend is not a liar. The reason for the loss of some low-end truck is a loss of exhaust gas temps. The turbocharger is due to the pressure and heat. The hotter the exhaust, the more they expand and drive the turbo. If we want to install a free flow exhaust which lowers the temperature, weis something to see slower spool up, ceteris paribus. Where there was a restriction in the stock exhaust, the exhaust gases causes temps to be higher than at any time, now the temps drop quickly, and have to warm up before the turbo will be back to the spool. This is a big deal? No

Most of the people, a sort of low-end programmer, fueling has never noticed you have added increased. These slowly reel is more evident on a truck automatic transmission as standardto operate based on location, in the lower speed range. Again, this "loss of low-end torque is usually only noticeable when the truck is cold or has sat idle for several minutes. Once the engine reaches normal operating temperature, you should never notice it at all . What you should notice improved performance, higher consumption and lower exhaust gas temps.
