So, this weekend I put on a new timing belt on the Jetta. The pipe and intake manifold were cool to the touch and the compressor discharge pipe was hot you could not hold your hand on it. Initially confused and alarmed, I pulled the compressor discharge pipe off and there was no water at all in it. So I opened the airbox up and felt the filter, which was dry.
It was a humid day, and raining on and off, nothing heavy though. I have a good understanding of physics have taken many classes , but was quite surprised to see the amount of water that was inside this pipe. I wish I would have taken a picture. Have others seen this before? Are there any harmful effects of ingesting these drops upon the next startup? Any remedy? Your thoughts are welcome. Farfromovin Torque Addict.
Wow, I have no idea why so much water was in there. I have never seen such a condensation buildup inside charge pipes. I can pretty much guarantee that it will do nothing to your engine though. It takes a lot of water to put the fire out, even at idle think water fountain. Raising air pressure lowers the saturation temperature rapidly. So with boost on and high humidity, condensation will occur in the intercooler. Normally it just blows through the engine, where all the engine bits are well above saturation temp, so no issue there.
Freezing is an interesting situation in cold temps On the marine engines I work on, running 25psi boost with a sea water cooled aftercooler, a gasket leak is shooting out air Condensation going through engine constantly.
No harm noted. Joined Oct 14, Location B. Canada TDI 18'6" welded aluminum jetboat with pd, gtbvl, and tuning by rub87, chev blazer with bhw swap, jetta alh with gtd vrk,. I have a tdi in a jetboat and have run into this problem.
With a large air to water intercooler and glacial water running through it that never gets more than a few degrees above freezing I would have water build up in the lower intercooler tank until it reached a level where it would send a gulp of water up through the core to the top tank and into the intake in a large enough quantity to put the fire out for a few seconds. I solved the problem by putting a brass pipe plug in the lower tank with a small hole.
Now the moisture that condenses in the tubes just drains to the bottom tank and gets blown out the hole continuously so it never gets a chance to build up enough to send a slug of water through the engine.
The leak is small enough it doesn't seem to affect the boost. Air-to- liquid intercoolers , also known as charge air coolers, are heat exchangers that transfer intake charge heat to an intermediate liquid , usually water, which finally rejects heat to the air. As its temperature climbs, its oxygen content density drops, so by cooling the air, an intercooler allows denser, more oxygen rich air to the engine, allowing more fuel to be burned, thus improving combustion and giving more power.
The intercooler does not have any oil by design or by functional requirements. The intercooler is a heat exchanger. So the answer is that you don't HAVE to have an intercooler , but it allows higher performance. A leak in the intercooler lines will fail to supply the required amount of air under the optimal pressure, thereby affecting the air-fuel ratio of the engine.
This will either cause the engine to run rich or lean. If the engine runs under a rich condition, the excess fuel will be expelled with the exhaust gases.
To put it simply: no, a larger intercooler will not really add any horsepower to your car. It does , however, give you much more wiggle room for a more aggressive tune without the risk of harming your engine. It should be noted, however, that too large of an intercooler can actually do more harm than good. This means the oil gathers in the bottom of the intercooler , reducing the performance of the intercooler itself.
Re: Are intercoolers directional? Intercoolers increase the efficiency of a compressor unit while an aftercooler will enhance the power output of the engine by increasing the density of the air entering into the engine. Intercoolers can also be seen in the reciprocating air compressor units which are popularly used to inflate the tyres. Painting the "front" only does 't affect the majority of surface area of the intercooler.
The "smarter than thou" scientific types here will argue up and down, but still no data to prove otherwise. Intercoolers are rated by " Effectiveness " and flow restriction. An intercooler sprayer is essentially a set of water jets that can spray down an intercooler and soak it with a liquid.
Cooling that charge will not only help you increase power to your motor, but if the intercooler is mounted in front of the engine radiator, will help keep engine temperatures cool as well.
The larger the core volume, the more air is required to fill the cooler. As with the piping size , we can equate this to a chart that can help you choose the correct size intercooler for your project. Once you know the Core Flow Area, divide that number by 0. Taking this part of what you asked, the answer is yes powdercoating or any coating will reduce an intercooler's performance.
Probably not by much, but definitely measurable. How slightly it reduces performance depends on the coating. But keep in mind that any coating is worse than no coating as far as heat transfer.
The primary function of a turbo is to make your car more powerful. Burning Oil. Burning excessive amounts of oil is typically a sign of a turbo failure. Excessive Exhaust Smoke. Loud Whining Noise. You don't need an intercooler for either, although you generally should have one for both. But a centrifugal supercharger is less contrained that way so they run an intercooler sometimes. You can also use watermist injection to cool the air charge. Intercooler size is relative to the size of the turbo, and the amount of boost psi being generated.
A turbocharger pressurizes air before pumping it into the intake manifold. Larger intercoolers will perform more cooling. However, too large a cooler can block air flow to other engine coolers.
