Thanks julio. My car has 8. The best article for a good experience with tubo world. In general it is a challenge to fit a turbo on simple [etrol engines. Need a lot of work and much money to be safe and smooth as required. My Question is? I want to Turbo my N46 engine, I already have a M52 Garrett turbo small one, low boost I wanted to fix it without changing anything in the engine but exhaust and airflow.

But, while the turbocharger does add power, it can also damage or even destroy your engine if used improperly.
Plus, the added power can increase wear on your clutch. One simple way for a previously-turbocharged engine to make more power is to crank up the boost settings. However, not only does that put more stress on the internal components, but it also increases the change of premature ignition. And it can damage your engine even more. To avoid this, in addition to intercoolers, sometimes turbocharged engines will come with water injection.
This cools the incoming air, even more, making it denser and preventing detonation. Knock prevention is also why turbocharged cars often require higher-octane fuel. The concept of a realistic goal needs to be stressed in order to ensure maximum performance and satisfaction. Sure, everyone would like to have a mega-horsepower vehicle but past a reasonable limit, as the power goes up, the reliability, drivability and day-to-day utility is diminished.
Things are more likely to go wrong, wear out and break down as the output climbs. Most project vehicles can fall into one of the following general categories:. The first step is to read the Turbo Tech Expert section. This article explains the reading of a compressor map and the equations needed to properly match a turbo.
The examples given, however, are for gasoline engines, so we are going to work some additional examples here using those same equations but with a diesel engine. This includes vehicles up to HP over stock.
But wait, this power level can be accomplished with just a chip or tuning module. So why bother with a new upgrade turbo? An upgrade turbo will enhance the gains made by installing the chip and other upgrades.
The extra air and lower backpressure provided by the upgrade turbo will lower EGTs, allow more power with less smoke and address durability issues with the stock turbo at higher boost pressures and power levels.
Because this will be a mild upgrade, boost response and drivability will be improved across the board. I have a 6. I would like to make wheel hp; an increase of wheel horsepower. So we will need to choose a compressor map that has a capability of at least Next, how much boost pressure will be needed? So now we have a Mass Flow and Manifold Pressure. We are almost ready to plot the data on the compressor map. Next step is to determine how much pressure loss exists between the compressor and the manifold.
The best way to do this is to measure the pressure drop with a data acquisition system, but many times that is not practical. For our examples we will estimate that there is a 2 psi loss. Therefore we will need to add 2 psi to the manifold pressure in order to determine the Compressor Discharge Pressure P 2c.
To get the correct inlet condition, it is now necessary to estimate the air filter or other restrictions. In the Pressure Ratio discussion earlier we said that a typical value might be 1 psi, so that is what will be used in this calculation.
Also, we are going to assume that we are at sea level, so we are going to use an ambient pressure of We will need to subtract the 1 psi pressure loss from the ambient pressure to determine the Compressor Inlet Pressure P1. With this, we can calculate Pressure Ratio using the equation. For the 2. We now have enough information to plot these operating points on the compressor map.
First we will try a GTR. This turbo has an 88mm tip diameter 52 trim compressor wheel with a As you can see, this point falls nicely on the map with some additional room for increased boost and mass flow if the horsepower target climbs. For this reason, the GT37R turbo family is applied on many of the Garrett Powermax turbo kits that are sized for this horsepower range. This category is for daily driven vehicles that have up to horsepower over stock or wheel horsepower.
