TD05H Compressor Wheels
The TD05H is available with a huge range of compressor wheels to dial in your desired peak horsepower and power delivery. Smaller wheel size will allow for faster spool but will sacrifice top-end power.

TD05H Turbine Wheels
The TD05H turbine wheel is available in multiple configurations to suits your budget and application. The STS (Superior Turbine Strike) turbine wheel is 5-8% faster to build a boost and, at higher RPM, prevents choking easier because due to its lower inertia and restriction when compared with an 11 or 12 blade turbine wheel. The STS 55 builds on this with a new 5+5 blade design allowing for even faster spool times and higher exhaust gas flow.

Important Notes When Upgrading to a New Turbo
Turbochargers are seemingly simple components but there are many external influences that can affect its performance and reliability as well as that of your engine and drivetrain. We have provided a list below with some important things to consider when upgrading to a new high performance Turbo.
Replacing a Faulty Turbocharger
Turbos rarely fail on their own accord and failures are typically caused by a problem elsewhere in the engine bay. If replacing a faulty turbocharger it is recommended to perform some investigation as to why the old turbo failed. If a pre-existing problem caused the old turbo to fail it is possible this will cause a premature failure of the new unit as well.
Installing a Turbocharger on a Freshly Built Engine
One of the most common situations we experience is a turbocharger failing shortly after startup, on the dyno or during the first few months of operation. This can be down to either improper pre-start preparation or due to the engine block and surrounding components not being correctly cleaned after assembly. Special attention must be given to ensuring all intake, exhaust, oil and coolant passages in the engine are cleaned of debris before installing the turbo. Should any contaminants make their way through the turbo it can cause almost instant failure.
Knock-On Effects of Increasing Performance
When installing a high performance turbo the existing powertrain will not operate in the same manner. Temperatures and pressures of almost all aspects of the engine will increase and if adequate measures are not taken it may cause turbocharger failure and/or engine failure.
An example of this would be increased crankcase pressure. Due to this pressure increasing it can increase blow-by and reduce the flow of oil from the turbo drain back to the oil sump. Additional blow-by will result in oil deposits in the intake, turbo and intercooler system. Reduced oil drain can cause oil to pool in the turbo cartridge and cause smokey exhaust and bearing failure. It is recommended to upgrade the engine breather system and install oil catch cans or air/oil separators to mitigate these potential problems.
New Turbo Pre-Start Checklist
The first stages of running a turbo after a new installation is crucial to its performance and reliability. We highly recommend looking over the following checklist after installation but before starting the engine for the first time:
Oil Supply
Oil is crucial to the operation of a turbocharger as it can see rotational speeds of over 100,000rpm. Failure to provide a clean and consistent oil supply can cause an immediate failure. If replacing an old turbo it is recommended to replace the oil feed hose and any fittings or filters between the engine and turbo. Certain vehicles run banjo fittings with an internal filter screen which should be replaced when installing a new turbo and checked regularly.
Oil Return
Whilst a turbo needs oil to operate reliably it also cannot have too much inside the bearing cage and must be able to exit from the turbo freely. Special attention must be paid to the oil return/drain hose to ensure it is free of debris and oil can move easily. If replacing an old turbo it is recommended to replace this hose. If oil cannot exit the turbo it can pool inside and cause premature bearing failures leading to oil leaking into the compressor or turbine housing.
Intake and Exhaust Piping
Ensuring all piping before and after the turbocharger is leak free and secure will help prevent turbocharger over-speed conditions and producing excess heat. A small boost or exhaust leak will mean the turbo has to work harder to hit target boost and could cause failures to the turbo or surrounding components.
Wastegate Setup
For internally wastegated turbos please ensure adequate pre-load on the wastegate actuator rod. A general rule of thumb is to have the clevis hole 1/4 to 1/2 a hole off the centre of the pin so that the rod must be "stretched" to slip over, creating tension and ensuring the wastegate flap is firm against the housing.
For both internally or externally wastegated turbos ensure the correct spring is fitted inside and a hose is connected from the compressor cover to the top of the wastegate housing.
Turbocharger Priming
After all above points have been checked over and the car is ready to start it is recommended to prime the turbo with fresh oil first. This can be achieved multiple ways but an example procedure is as follows:
- Install oil feed line to engine but leave the turbo end of the line disconnected
- Place the oil feed line fitting that's not connected in a receptacle to catch any oil
- With engine in a NO-START condition, crank engine WITHOUT firing until oil drains freely from the oil feed line
- Connect oil feed line to turbo (with restrictor if provided), and install the oil drain hose, leaving the engine end of the turbo oil drain hose disconnected and directed into a suitable receptacle
- With engine still in a NO-START condition, crank the engine WITHOUT firing until oil flows freely from the turbo oil drain
- Connect oil drain, and dispose of any oil caught in the receptacle - your turbocharger is now primed with oil and ready for first start
First Start
- Start the engine and allow to idle for approximately 3 minutes to purge any air in the system
- Check all unions and fittings are tight and free from leakage
- Check all hoses are routed away from heat sources and any potential chafing risks
- Stop engine, re-check engine oil level and top up as necessary
- Your turbocharger is now ready for use
