VW POLO modified turbine (9N)

Engine power
Prior to that time Mr. Ho in the modified POLO through some detours, which refers mainly down inside the cylinder compression ratio, how he solved the engine compression ratio is too high it? This is an intriguing question. With the vast majority of engine compression ratio down approach, they first consideration is thicker head gasket, according to standard practice to maintain its crankshaft size of tile, and then re-assembled engine, test. GT3582 turbocharger However, they soon discovered, just use a second spacer to lower systolic pressure in fact is not enough, the engine still appears from time to time detonation (of course there is also the ignition timing, cylinder temperature and other attractants), damage Pistons. After the final balance, they decided to adopt the method of grinding chamber down the engine compression ratio target of 9.0: 1 or so, this method before Ho's CCC racing on the modified time-tested, but is done in POLO 1.4L engine body it is not too extreme.

Do not do as well as the extreme peak turbocharged 1.4L engine this. Generally, 0.5Bar can only be regarded as a low boost, and this number is the 1.4L engine peaks. Therefore, Ho believes that since it is not high supercharged engine, it is even more suitable with an overhead Intercooler, after all street modified cars, sometimes talking about ease of use. If this is racing, it is another matter.

Because it is plug-turbine, it requires a suitably shaped exhaust banana, banana 1.4L and this exhaust is the choice to use the converted stores firing steel products. Renault scenic 1.5 dci turbocharger Basically, this homemade method is suitable for most plug-turbo models, but the weight of the turbine itself, exhaust temperature, high pressure, welding exhaust banana is undoubtedly a test effort thing. So, now there have been a lot of anecdotal correspond specific turbine models and the production of cast iron plug banana, it is more stable and durable, but the price is more expensive. Of course, I never said exhaust banana 1.4L now used are the slightest flaw, it works well, turbine therefore benefit, cost is also high. Then add about, now the engine using a TD04 turbocharger.
