Supercharger vs Turbocharger
A turbocharger and a supercharger both compress air that is entering the engine, which in turn increases the amount of oxygen available to burn fuel. This process results in more power being generated by the engine. Moreover, turbochargers are powered by exhaust gases, while superchargers are powered by a belt that is connected to the engine.
Automotive Turbo Repair
Do you need your turbocharger repaired, serviced, upgraded, or even supply a new one? We offer competitive prices on all turbo services. Contact us today!
Furthermore, when doing turbo repairs, our clients often ask us to upgrade their turbochargers during the repair. As this is an ideal opportunity whilst the turbo has already been removed from its application.
However, turbocharger upgrades can be carried out on your existing turbo at an additional cost. To sum up, we are market leaders in hybrid turbo technology, you can be sure that not only will we bring your failed turbocharger back to life.

Upgrading Your Turbocharger
They are many ways you can upgrade your turbocharger for better performance, give us a call today for more information or check possible updates below.
Turbine Wheel Cutback
Turbine Wheel Cutback is a machining process which enables the turbocharger to increase power output by reducing back pressure. This process does remove some blade material from the turbine wheel which normally results in a slight reduction in turbocharger response. If you're unsure of how back pressure influences a turbocharger imagine running a marathon with a finger up your nose!
Porting and polishing the Turbine Housing
Porting and polishing the Turbine Housing helps provide maximum gas flow, thus improving efficiency. It is usually carried out on the turbine housing inlet. Flanges can be gasket-matched if required to optimize flow.
Fitment of a Larger Turbine
Fitment of Larger Compressor Wheel, allows the turbocharger to flow more air. It does this in two ways. - Firstly, the larger turbine wheel can drive the compressor wheel harder resulting in more airflow (more airflow equals more power potential). Secondly, the larger wheel reduces backpressure in much the same way as a Cutback.
Uprated Actuator Turbocharger Fitting
Fitting an Uprated Actuator allows higher boost pressure to be run. The actuator governs when the wastegate opens. A stronger/uprated actuator means the turbocharger will run higher boost, usually equaling more power, before the wastegate opens.
360 degree Thrust Bearing Turbo Fitting
Fitting a 360 degree Thrust Bearing increases the reliability of your turbocharger and allows a safer way of running high boost pressures. The thrust bearing is under heavy pressure when the turbocharger is operating, the larger surface area of a 360 thrust bearing. As opposed to a traditional 270 degree unit, is better equipped to cope with these axial loads.
Restrictors
Restrictors are used in motorsport to "cap" the airflow and therefore, the power a car can produce. At Autonic Turbo Diesel we can machine your turbo to accept a restrictor. Similarly, we also offer restrictors in all the standard sizes so we can supply as well as fit, if required.
Modifying the Compressor Backplates
Modifying the Compressor Backplate allows the fitment of a Larger Compressor Wheel an essential part of the hybrid process.
Twin Seal conversions
Twin Seal conversions pre-date Staggered Gap Piston Rings and are used on older turbochargers where staggered-gap rings are not available. The process involves careful machining of the piston Ringland on the shaft. And the seal bore area of the bearing housing to allow a second piston ring seal to be fitted. This reduces oil weep age on cars with low back pressure exhaust systems or higher than usual crankcase pressure.
Ported Automated Turbo shrouds
Ported shrouds help prevent surge by equalizing air flow on the secondary blades of the compressor wheel. Allowing the turbocharger to cope with higher boost levels at low engine RPM and light throttle loads. A ported shroud conversion will also improve the overall efficiency of the compressor wheel. The existing compressor cover can (potentially) be machined for a ported shroud or a replacement cover with a ported shroud can be supplied.

3 Common Turbo Failure Modes
If you think your vehicle might have a turbo-related problem, do check our contact us for a complete turbo-diagnostic check before you replace it.
1. Foreign Object
The turbine and compressor wheel assembly can rotate at up to 240000 rpm when in use – that’s 4000 rotations every second. At these speeds, even small components have a lot of inertia (stored energy ready to be released). Consequently, the contact of any dense particles even non-metallic deposits such as carbon. Build up into the internal working of the turbocharger can cause immediate and total failure to the turbo. This is known as a Foreign Object Impact (FOI) failure.
2. Oil Starvation
Most modern turbochargers utilise a ‘plain’ bearing system to control the movement of the main shaft. This means that they rely on a film of high-pressure oil to support the shaft, and consequently there is zero contact between the shaft and the housing. The shaft effectively ‘floats’ while it rotates at very high speed. Despite the film of high-pressure oil. The velocity with which the shaft must rotate in a modern turbo to generate the required flow of air (over 240,000 rpm – that’s 4,000 rotations per second !) However, resulting in a very rapid build-up of heat.
3.Oil Contamination
Maintaining the quantity of oil to your turbocharger is vitally important in maintaining the performance and longevity of the engine. However, it is equally important to ensure the optimum quality of oil too.
Turbocharger bearing systems are manufactured to high precision, with the dimensions measured to within one micro that’s around 100 times smaller.
With the fine tolerances necessary to obtain such high shaft speeds, and thus the pressures necessary in modern fuel-efficient engines. It comes as no surprise to learn that the lubricating oil must be totally clean and free from contamination, such as:
- dilution from water, coolant or fuel.
- metallic particles created through engine wear
- long-term poor maintenance of the oil and lubrication system.
