Dedicated turbo oil supply

Feral: That is the same thing I'm coming up against, a low turbo (but it's far from the only reason )

No reason to tell you to blow it out your arse.

I just read the whole thread and have a fair idea what the original posters plan is. As far as I know the he was planning on using a stock 4AGE exhaust manifold to modify into a turbo manifold which mounts the turbo very low and does not allow a decent fall to the sump.

ahhh ok cool. It all makes sense now.

Thought there was a bit of effort there for no real gain but there is a reason behind it.

[mullett]

yes to all of the above It IS a fair bit of effort, and there's a good chance I won't do it, I just wanted to throw the idea out and see what kind of reactions and experiences people had with them I appreciate what you're saying Mick, and in the real world I guess there's a good chance it wouldn't work well/would fail, I just wanted a bit of a theoretical discussion...seems like it's more effort than it's worth. And, on the bright side, looking at those surge protectors for the engine: I could make one easily

Any thoughts about diesel turbos? they don't get that hot to warrant turbo-timer / cool down? or they need it even more (if i'm not mistaken it runs at higher psi than petrol engines, however the engines don't spin that fast and don't generate so much heat)..

AFAIK, most diesels need a cooldown just as much as a petrol, they work damn hard most of the time, and alot (like tractors) are expected to make full power for hours on end...

but funny they dont come with turbo timers! i have watched the oldman drag a trashcutter threw the paddock under full load and pull up after a few hours and turn it off soon as the wheels stop! lmao poor turbo. i keep telling him, but i might aswell be talking to the tractor wheel

[mullett]

hahah, that's true, although a few have stickers asking for a few min to cool down Most factory cars don't have warnings either, I had a Cordia turbo and it had a huge sticker on the door about turbo cooldown times, but my dads new XR6T doesn't even have the slightest thing hidden in the manual somewhere...although, they only run 5psi or something...

it was mentioned on this thread.. new turbo designs, metal blades, ball bearing turbines etc etc allow the turbo to be trashed harshly and still survive..

could be the manufacturere weren't thinking that drivers would drive at full speed, and suddenly turn off the engine... before arriving at the destination, there would be a bit of slow driving and such eh? and also if you drive without boost, you don't really need to wait the minute to shut down?

and also with the XR6... probably low boost plus good lubrication and a high-tech turbo = turbo not really getting that hot to warrant a timer or the minute wait before shut-down? hm... could be a design thing as well...

oh yea.. anyone familiar with the fully auto turbo timer? it senses loads and decides how long before shutdown.. cruising on boost and it'll show 3 to 4 mins.. and cruising off boost it'll show something like 30 seconds to 1 min... but when driving slow to the destination, the time becomes less and less.. and the moment i'm about to turn off the key, it shows 10 seconds (most of the time).... just a thought... hmm..

[Ghetto-AW11]

turbo timers are stupid. Just dont thrash the car before your destination, and give it 20-30seconds before you shut it off.

[mullett]

mmm, my thoughts exactly. Turbo timers are good for saying: Hey! I've got a boosted car! And it's sitting in the carpark running! If you can splice 2 wires together, it'll keep running! STEAL IT!

There's soemthing...not right...about walking away from a running car...

but turbo timers would be good for silly farmers and some people that drive hard but dont understand engines.

The original poster is wanting to setup a seperate oiling system for the turbo as it will be mounted too low for effective return to the sump apparently. I just don't see how an oil accumulator could be of any use to the original poster. I guess I'm just not equipped to tell everyone what it is they really want or need.

In that situation, I'd be tempted to try an electric lift pump to pump the oil back up to the rocker cover after the oil has gone through the turbo.

[kingmick]

or change the manifold or modify the manifold.

[Ben Wilson]

That's the obvious solution, but there may well be other packaging issues.

Yep this is what is done on some Porsche's a small sump on each turbo with a scavenge pump to move the oil back to the engine.
