Do superchargers need lubrication and cooling just as turbos?


Do not fear the orange can.

I put an aftermarket Vortech supercharger on my 5.0 Mustang years ago. It had a pressurized oil feed line with a drain line back to the pan.

Lubrication yes. Cooling no. Turbos need cooling because they are driven by hot exhaust

They are lubricated, and if you mean charge air cooling, then yes to that as well.

Most OEM and aftermarket Eaton and twin-screw SCs have permanently sealed bearings, these days.

Yes, but are their gearboxes?

The Hellcat, and Audi 3.0 both have serviceable superchargers. Is there anything more recent?

Mobil AGL or ZFN-L-3001 are perfect as well, if you happen to have convenient access. wink

Honestly, meh. A lot comes from people never servicing them which leads to failures. One of the pages on FB I follow is a Saleen specialist, but also does a lot of servicing on other roots/twin screw style superchargers. A little money and time spent changing fluid goes a long way. Also they recommend at some point sending them in for a basic refresh like you would do any racing part component.

Neither my Hellcat, nor the Magnuson TVS that I installed on my '04 GTO, have/had any way to change or add oil. Dodge had an early ('15-'16) batch of twin-screw IHI SCs with bad bearings. They were replaced under warranty rather than repaired or serviced. '15 Hellcats were warranted for a 100,000. '16 and later have 60,000 mile warranties.

Superchargers used to be part of the motor case and were lubricated by the motor oil, when this became too expensive they made the add-on supercharger, but I don't know if they have their own reservoir or if there is a motor oil diversion to lubricate it.

It all depends. Your typical roots or twin screw like an Eaton, Kenne Bell, Magnuson, Edelbrock, or Whipple have their own reservoir. Up until recently Procharger was the only centrifugal supercharger to have its own reservoir while the others had feed and drain lines. However I think I have seen some Vortech units with self contained reservoirs.
