COMPRESSOR WHEELS DESIGNS

Flatback

"Flatback" is initial compressor wheel design which later evolved due to poor response to stress , but is still fitted in some low boost turbochargers.

Superback

"Superback" is updated design with extra material added to the back (exducer) of the compressor wheel which meant improved response to stress, managing greater RPMs and higher pressures.

Deep superback

"Deep superback" is continuously improved strength of compressor wheel with more solid structure keeping stress from the hub.

Extended tip

Adding extended tip provides faster and more efficient boost response instead of adding more mass with larger exducer diameter and loosing spool speed.

MAIN COMPRESSOR WHEEL DIMENSIONS

D - Total height

E - Tip height

F - Shaft diameter

A - Inducer

B - Exducer

C - Blade height

While there are a lot of compressor wheel dimensions which are required when constructing impeller there are six main dimensions which are the most important when choosing the right one for your turbocharger. Standard compressor wheels have part numbers, you can always search find right impeller by entering it's number or turbocharger to which it belongs, but for hybrid turbochargers these dimensions are essential when picking your performance impeller.
