Dump Valves for Turbo Diesel Cars
The need for speed of many people has prompted them to ?turbo charge? their cars. So, like in the film Fast and Furious, they?re revving it up where it?s not illegal and they?re having a grand time unless they have forgotten to look after their supercharged engines. Without this nifty gadget called dump valves their turbochargers are prone to damage. That works well with petrol-infused cars. What about turbo diesel dump valves?
First, let?s see what a dump valve does. A dump valve serves as the absorber and of extremely high pressure, which it releases to the atmosphere or back to the inlet. It?s the bypass valve that protects the car?s turbo from taking so much pressure than it can cope with.
When the car is in full acceleration, it creates pressure called boost. When the driver suddenly decelerates, the throttle butterfly closes and air gets compressed but there is no other way for the excess air to get out. The unused boost then goes back up through the intercooler, creating pressure at the rear of the turbo. This pressure acts as a hold on the turbo and tries to prevent it from spinning.
How does it perform its purpose? The dump valve will be the leeway, the escape hatch if you want to put it that way. It releases the pressure in two ways: into the air outside or back to the air intake system.
Atmospheric valves dump the extra boost to into the air giving out a ?whoosh? sound that the riders love. Re-circulating valves dumps back the unused boost with minimal sound.
As a result, this add-on provides significant decrease in turbo spool up time and there is big improvement in the car?s response between gearshifts. Since there is little lag on the turbo, the next boost is timely. This means increased torque at lower revs.
What about turbo diesel dump valves?
If you are asking if you can use a petrol dump valve in your turbo diesel car, the pointblank answer is NO. Petrol dump valves are useless to your car because diesel cars have different engine set-up from petrol turbo cars.
Turbo diesel cars do not have the same throttle plates as in a petrol turbo car that control the engine speed. In a diesel car, the engine requires all the air that the turbo charger can supply. It thrives on compressed air for its cylinders to function optimally. A diesel dump valve will only provide the sound but no additional speed.
Diesel dump valves therefore, are not really needed because your turbo diesel car thrives on the high pressure build up. Should you want to install a diesel dump valve in your turbo diesel car, you only get the 'woosh' sound when you change gears.
There isn't much point in arguing about the need of the dump valves in a turbo diesel car. You could fit them if you want the performance sound but ultimately, it's down to individual choice and preference as not everyone who drives a turbo diesel wants to fit a dump valve. Some may even find the sound to be repulsive!
