* Target HP is near center (target) of compressor map on highest efficiency.  Max hp is recommended max HP in safe map based on the individual turbine housing. I.e. please be informed that each turbo can deliver more power than recommended max hp, as we do not list or recommend power levels at compressor choke lines as seen by other manufactures. Also note, that all ratings are based on regular pump gas.

** Our low friction trust bearings in C3-C5 turbo family are special racing trust bearings, they provide 15% less friction compared to traditional trust bearings.





Below overview list other brand turbo models within in a "ball park" range compared on compressor wheel inducer and turbine wheel exducer sizes. The purpose of this overview is to help our customers index size in between different brand turbo models.

1 Year Warranty Program


IMPORTANT: As all of below check lists will have a immediately impact on the life span of any turbo, our 1 year warranty program require all of below notes have been performed and checked. This is common "best practise" for installing and running a high performing turbo application, regardless brand or supplier.




Oil supply – Use a 2-3mm inner size diameter hose as maximum. Larger diameter will cause too high of oil pressure and oil will be forced out of the bearing sealing into both compressor and turbine. Sudden blue smoke out of exhaust and oil in the inlet system / intercooler is an indicator of too much oil supply or too little oil drain. This will damage bearings in turbo quickly.


Oil drain -  Minimum 16-18mm inner diameter (AN 12-14) all the way including adaptors and flanges. Port flanges and adaptors if necessary. Always keep close to straight angle down in direction, and with absolutely no backpressure. Leave  oil return above oil level in crank case.


Water cooling – Use the water cooling (C1-C2 turbo family only) to keep oil temperature healthy around 80-90 Celsius. Without water cooling oil temperature goes up to around 150 Celsius in running mode, and will exceed 200 Celsius immediately after instant shot down if no "shot down" cooling is performed .


Shot-down Always idle engine for min. 3-4 minutes after driven hard to cool oil before stop. If not performing the idle cool-down, bearings might exceed 200 Celsius for 5 minutes or more and will "cook" the bearings. This is regardles what brand turbo or bearing system you are running.


Rotating compressor housing – Never rotate the compressor house with bolts tight or finger-tight. Remove compressor housing completely when rotating. The inner rubber ring gasket will take damage from the friction of rotating the house. A broken rubber ring seal will cause leakage. Use a heat gun  to warm up and expand compressor house if it wont come loose.


Vacuum in crankcase – You want vacuum in your crankcase to ensure oil flows in the right direction. If not running a vacuum pump (which most people do not), then ensure a 16-18mm (AN 12-14) hose connection between the inlet pipe before the turbo to the outlet of your oil catch can tank ventilation. The catch can tank will ensure no oil goes to turbo inlet, and the turbo inlet will help create the vacuum your engine needs to operate at its best. Target vacuum is 85 Kpa or lower. If no vacuum is present, then backpressure might go into the turbo oil drain and will damage oil seals and cause turbo shaft to come loose. Piston rings also get more stress and more oil will go into to the combustion chamber. This will increase the risk of detonation as your fuel octane decreases from the oil.


Pressure test - Alwasy, as in ALWAYS! perform a leak test of your inlet charge pipe system. If you think your system is tight and free from air leaks, you properly with 90% certaincy have an air leak somewhere. Often the air leaks can be quit substantial and you will never hear it while running your engine. What happens is, that the turbo now has to overvome that air leak and will rotate with way too many shaft rpm's to get on boost target level. The turbo now spins right out of the map and crossing choke lines if air leaks are big enough. This will not only delay your spool-up time in the range of a few houndred to 1500 engine rpm, but it will damage your turbo sealing very quickly. You dont want late spool-up and you dont want to run your brand new turbo way cross the choke lines. Many tuners and builders are not aware of this, and when not dealing with air leaks they tend to blame all other components (including turbo) for missing performance as rational explation. Instead they/ you NEED do the home-work correctly from start and perform a proper leak test.





Additional notes


Shaft play - Our low friction race trust bearings (in C3 - C5 turbo family only) runs on a fine layer of oil. Without oil or oil pressure, a small amount of play up/downwards is normal. You will feel this on brand new turbos. it is normal, and should be this way. Also note, warm oil will increase the play a little over cold oil.
