Revive Turbo Cleaner

How is this applied to a twin turbo 3L engine? Wouldn't you have to be very specific as to RPM at application to ensure that the second turbo gets a dose?

The instructions are quite clear to apply the cleaner and as you'll be directing it straight into the inlet air tract, it will pass through both turbo compressors.

You'll need a helper to either sit in the cab and press the throttle or apply the cleaner.

If memory serves me correctly:

1st dose applied directly into the air intake downstream of MAF and air filter when engine is cold @ 1,800 RPM

Wait 5 minutes for cleaner to loosen/soften carbon/oil deposits in both air inlet and exhaust outlet.

2nd dose @ 2,200 RPM using the remaining cleaning fluid. This is when you'll see smoke, carbon deposits and steam coming out of the exhaust which is a by-product of the cleaning process.

Assemble everything then take the car for a "spirited" drive which will blow the remaining crud out of the exhaust.

Easy peasy!

Pretty sure the issue is that the secondary turbo won't get engaged while sitting in neutral.

The secondary turbo being fixed vane doesn't have any moving parts to get stuck.

I used the same delivery method that is used for cleaning my helicopter compressor......Filled up the pump spray that I use with round-up to kill weeds around the house, adjusted the nozzle for a fine spray and away I went. Worked a treat on the D4/D2/Defender and the longer hose and hand-piece meant I didn't have to balance an upside-down spray bottle (And saved some $$ by not buying their recommended spray bottle).

Only horror story I could imagine is either dropping a spray nozzle or some metallic component into the open compressor while cleaning it or, being impatient and inundating the compressor with far too much cleaning fluid at once.

A fine spray and patience is the key ;)

Good feed back...

When I first read this thread I went looking on the web for peoples experiences / reviews..

Got a 50/50 result..

Guessing it really depends how far down the road the compressor already is before they choose to try the product..

Good to see your comments and thanks, I too have now gone ahead with my Disco service guys and actually thought to reset the trip computer for the freeway journey home (approx. 20 Kms at 100 kph - unusual to be able to do that nowadays in Perth). Car went really well 7.3 L p100 Km and I have noticed far less fumes in the rear view. Hopefully no horror story down the track.
Thanks - my first post, good to have your feedback, there are other Disco people out there!

But could still suffer from build up on the vanes affecting the performance?

So from the SDS it looks like this stuff is nonionic surfactant (Polyethylene glycol sorbitan monolaurate, Polyoxyethylenesorbitan monolaurate) in Propylene Glycol and Water.

It would cost less than $5 per litre to make up yourself. How much does the commercial product cost?

There's no ability to build-up carbon on the inlet side as EGR is post turbo. I've seen the result of a mechanic's rag sucked in though but that's not fixable with anything less than a new compressor wheel.

Superheated steam on the exhaust vane would probably clean that side!
