Whats a Dry Turbo

Hi Guys
I was reading a catalogue and they advertised a Garrett T3/T4 Hybrid Dry Turbo rated to 250 hp and I was wondering what the "dry" part meant. At first i thought it meant not water cooled but then looking at the pics I cant see an oil feed line for the turbo. Is it that right? Can they build turbos like that? Any advantages / disadvatages (like not blowing up!)
Thank guys, hope it wasn't a dumb question!

unless you're turbo is designed to mix water and oil for you, then i'd assume that a dry turbo has no water cooling, all turbos have an oil feed line (and of course a line to return the oil to the sump).

hmm, so even the ball bearing and cermaic bearing turbos have oil feeds?? i had thought that some were water cooled and didn't need oil feed?? (off to google i go  )
also thought that water cooled turbos are not as common as oil cooled/lubed turbos as stock fitment....

AFAIK, all turbos are oil cooled. Some have the additional benefit of water cooling.
Water cooling is rarer on OEM stuff, but pretty much all turbos these days have water cooling also.

I dont know how correct it is..
But ive heard from several sources of places that build Perf. motors that water cooling on a turbs is a waste of time?

No, all turbos are oil lubricated, with the side effect of some cooling while being lubricated. You can also have fully dedicated oil cooled units too, however water cooling is much better (and no, the two liquids don't mix!). The service life of an oil cooled turbo is much shorter than a water cooled one, hence the reason many new turbos are now water cooled over oil, and yes, ball bearing turbos and turbos using ceramic wheels are also oil lubricated.

We had a fair chat with the guys from Garrett on this topic when we toured their facility.
Apparently before Garrett were in big with Nissan they used to do a lot of work for Toyota, however Toyota wanted to build water coole3d turbos. Garrett believed that water cooling turbo's was a waste of time and they would not make water cooled turbos. This is when Toyota decided to do their own turbo development and production.
The manager from Garrett was pretty coy about this due to the fact that Garrett then went on to use water cooling in basically all of their turbo's and are only recently starting to renew their relationship with Toyota.

As a side note, i've seen in a magazine that there is a company in the states (not garret) who make turbos with an internal oil resevoir.
I've seen them used on a modified twin turbo porsche boxter. Guess they were a bit hard up for space and didn't want to run oil lines 
I'd hate to see what the oil would look like if you forgot to change it

Never mind the oil; what would the turbo look like?

Ask and you will receive
They've also got the Variable Area Turbine Nozzle thing going on, which i think is pretty damn cool.
