turbo oiling

[miekedmr]

I was just wondering if theres anything you could do to increase the longevity of a turbo as far as the way it's oiled..
I would imagine theres an ideal oil pressure you could keep it at for the best lubrication/cooling without overpowering the seals. Has anyone heard of an oil pressure regulator being used for this? Or is the pressure of the engines pump never too high when there's an adequate drain on the turbo?
What about the type of oil? Would a turbo be happier with a different oil weight than is ideal for the engine?
It could have it's own oiling system if thats the case.. I'm sure theres a pump that could be belt driven and would work well for that, somewhere out there.

Dude you are trying to reinvent the wheel. The pressure doesn't need to be high, it just needs to be oil in there. Just allow the car to properly cool after heavy runs with a turbo timer. Better yet use synthetic oil.

Vac to the crankcase will help as well, along with proper priming of a new turbo.

By rule of thumb, a turbo never needs to see more than 40-45psi of oil pressure.

On some SBC / SBF applicatoins, there is indeed a bleeder that regulates the oil pressure going to the turbo.

The key to making a turbo live is:

a.) Priming. The first 30 minutes of a turbos new life are the most critical

b.) Oil quality. Don't go to walmart and buy the .99$ bargain bin

c.) Heat. As with most any mechanical system, heat is the enemy. Cool that oil down!

d.) Contamination. Keep that oil clean. A good filter is a must. Change the oil regularly. No excess fuel or water is wanted here!

e.) Boost controll. A good boost controller and no boost spikes

f.) BOV. Again, another area you don't want to cheap out on. Make sure the BOV is of good quality, can handle the boost youre running and is as close to the throttle body as possible. Alot of thrust washer failures are due to bad BOVs.

g.) Good vacuum on the crankcase. This is critical to the turbo working correctly in the oiling department.
