Diesel engines are designed to be a workhorse—operating within a very narrow RPM range and under certain conditions, usually WOT. High performance operation—response, spool-up, or fuel efficiency has seldom been a consideration. But a turbo upgrade can make significant contributions to performance, fuel efficiency and emissions control. Turbos are complex to install and it is recommended that they are installed by a qualified technician, as an incorrectly installed turbo can damage or in some cases wreck an engine.
Some things to keep in mind when selecting your turbo are transmission type, gear ratio, tire size, elevation, type of driving and where you want your power to be. Those with an automatic transmission, with gear ratios that keep you running at lower RPM's, will prefer smaller turbine
housing. Also, stock 3rd gen trucks run smaller turbine housing so many customers will prefer the smaller performance turbine housing.
When running an adjustable level "box", at lower levels may not provide enough fuel and/or timing to run a performance charger efficiently. Drivability issues will intensify as the compressor size increases, when the box settings are low.
Another thing to consider is "surge". Some call this compressor surge, technically it's not compressor surge, but turbulence. This can happen with all turbos, including stock. This turbulence issue occurs on about 10% of compressors that are larger than 62mm. Since
this is turbulence, it is erratic. It can usually be "driven around" easily with a manual transmission. Automatic transmission makes driving around the issue more difficult. Often something as simple as a Turbo Air Guide will minimize the condition.
Here at Rocky Mountain Diesel Injection our highly qualified staff have recieved training directly from manufactures on how to install and maintain their products, we can also give you well informed advice on what would be the best size and type of unit for your vehicle.
Diesel Tuning Systems
Tuning systems download new information to your vehicle's computer, and stores the original information in case you ever want to go back. This information effects and fine tunes all aspects that effect your vehicles power: air/fuel ratio, fuel injector flow rates and spark. timing. With tuning systems we can also tune automatic transmission for maximum acceleration and a performance feel. Superchips can deliver your vehicles optimun power, performance and fuel efficiency, without have to exchange parts on your vehicle.
