Turbo Placement/Mounting Question.

[duramaximizer]

When one mounts a turbo-any turbo, is it a must that the turbo shaft is parallel to the ground? If so, why?

My thought process is that a person could eliminate bends by a mounting the turbo on some sort of angle.

I think its something like 15 deg you dont want to go past

According to Garrett that is correct.

I guess I will take that as gospel then. Shit.

It has to do with oil draining. If the oil does not drain freely, the shaft and bearings can coke up.

That's interesting so it's gravity feed and drained no pressure?

Pressure fed

hmm thats interesting on the draining......the oil pressure coming from the feed will not push the oil out the drain.... i would think that is even better for the turbo because there is oil on both sides constantly no just being pushed onto one side and dripping off the other.

The oil needs to leave the turbo fairly quickly, and not sit in contact with hot parts, or the oil gets so hot it breaks down into carbon or varnish. The turbo gets hotter than oil can handle.

That I understand what surprises me is since I new it was pressure feed why is gravity needed to return or exit? Under idle (low pressure) I would imagine a slower flow and after a hot (glowing) run some undesirable effects on the oil,As I've seen turbo cool down devices.

So basically it's for low RPM I'm assuming the slight degree in mounting. There is no actual cavity ?

As long as the shaft is parallel to the ground, does it matter if you turn the charger up or down?

 

[duramaximizer]

no.
