Evening all Just a quick question, I was flicking through an old edition of Fast Ford from 2002 and came across an article on Turbo Guards. Basically you fit a T-piece to the turbo oil feed, when the car is started the oil is diverted to an accumulator tank (cant imagine that would do the turbo any good), when thats full a pressure swith in the T-piece diverts the oil back to the turbo. When the car is swithed off the drop in pressure releases the oil in the tank back to the turbo, same as a turbo timer without leaving the car running.
So what do we think? good or bad? has anyone ever used one? They are made by a company called Agriemach.

never heard of that before,what about a turob timer are they any good

Sounds like a great idea in theory, but like you said it the time when the accumalator is charging which is the problems, no good protecting the turbo at the end only to dmage it at the start! Although i imagine they may have a soloution for that, lots of people must be thinking the same thing, i'd be very interested to see what you find out!

Thanks

Like Matt says, running the turbo dry on startup doesn't sound too great! There are a lot of things you can do to give a turbo an easy ride; letting it warm down properly after driving.....drive the last two or three minutes on nice low revs and low boost....and a lot of people blip the throttle and turn the ignition off after a drive. That can spin the turbo up to 30,000, maybe 50,000 rpm and then leave it spinning in bearings that aren't having oil fed to them. Just a few things to think about before buying fancy gadgets anyway!

I understand that Heeman10 but there may be the odd occassion when I dont have time to sit round for 5 mins letting it cool down, just looking at safety alternatives

[heeman10]

Yeah I wonder about that too, nearly always end up in a hurry when I'm driving! Might employ a small Thai boy to sit in my car for 5 mins with it idling then switch off and lock up for me

Not sure on the idea as the system isn't pumping oil around the turbo, just dripping it in.

Best bet is a turbo timer... there must be a reason why people haven't heard of this system

[ianFRST]

aii, agree with andy. ive never heard of it before

After the engine has run for about 30 seconds the Turbo-Guards reservoir begins to fill with oil and does so until the pressure reaches the psi that the engine is supplying. This pressure remains as long as the engine is operating, taking nothing away from the turbo.

The Turbo Guards reservoir has a capacity of one half litre and has a pressure rating of 1400lbs.

The units ball check valve system can carry 11 gallons of oil per minute to the turbo, the check valve in no way whatsoever restricts the oil flow.

HOT ENGINE SHUTDOWN
At the very moment of hot engine shutdown, before the engine pressure drops to zero, the Turbo-Guards ball check valve closes. This directs the oil still under pressure in the reservoir into the turbo (which is still rotating at high speed). This special lubrication continues for a period of about five minutes protecting bearings and carrying away some of the built up heat.

COLD STARTING
When the Turbo-Guards check valve closes at hot engine shutdown it retains oil in the feed line. So the next time you start up the engine, lubrication is immediately available to the turbo.

buy a turbo timer...........iv got a GREDDY one in the garage somewhere , never fitted it [ERRR] i was told it wouldnt work with my clifford

Now that makes sense, seems like a very good system!

That's more like it! Just because we haven't heard of something doesn't mean it doesn't work Sounds quite cool. Turbo timers are all well and good if you can secure the car thoroughly and walk away, engine running, confident it won't get stolen. All/99% alarms are made redundant if a turbo timer's used, and you'd lose your car AND any cover if it were stolen.

Thanks Pisko, Fast Ford only gave limited info
