I'm a fan of the bogaard turbo timers. However I think you will have to find a pretty special auto-elec to manage to fit one.

I imagine that fitting one will lead to a huge amount of problems, such as not being able to lock the car until the engine is off etc.

Not sure why you'd really need one?

This is true, just sit in the car for a min or two afterwards, or drive at low rpm for the last bit of your trip.

We only use them in tractors which are running at full boost for days on end, and even then we usually hit the kill switch because you end up crawling around at idle for a while before shutting down.

thaks for your reply guys, turbo timers are a must have item, its cheap insurance, running the engine for a minute or two is not enough, a minute or two might be fine for short local trips with minimal load, drive with a camper or in low range working it hard, this generates way too much heat for that short amount of running time, once the engine is shut off there is no oil supply which equals excess heat and bearing failure, these turbos aren't cheap to replace, then take into account the engine damage- even more $$$$$$, to wooleys reply of drive at low rpm last bit of the trip- these turbos are variable nozzle type they produce boost just of idle so even driving at low rpm will not fix the problem.
cheers guys thanks for your input

I would use one of the Japanese brands,Blitz,Greddy/Trust or HKS. They all make excellent quality turbo timers. You wont be able to use your remote to lock the car but the key lock works fine.

too bad that 150's don't have keys, Auss15.

I wouldn't call them a must have item, The engine can only produce so much heat, 1/2-5 minutes is more than enough depending on how hard you've been working the engine.

You can only leave an engine idling for so long. Hell, John Deere recommend 5 minutes for their big engines when they've been running for over 12 hours, we run our tractors for days at a time at full chickens and let the turbo timer do its 5 minute 'cool down' and have done so for years and never had a problem.

At the end of the day, how much do you think your motor is going to cool down from 4-5-6-7-8-900 degrees in 5 minutes... not much.

Your prado will be fine.

hi wooley
5 min is plenty of time i know that, you would be amazed in how much heat is removed in that amount of time, with any engine being shut off after running at any load with no idle down time there will be a temp spike (no oil/ air/ coolant flow) regardless being petrol/ diesel- turbo , your figure of 900 degrees is excessive, after 600 degrees celcius (exhaust temp) your pistons will melt regardless of make or model, i hope you wouldn't suggest that pyrometers are needed either, im looking at cheap insurance with the amount of times the missus shuts it of with little or no idle down time is not good, i would rather pay $600-$800 for a turbo timer/ pyrometer any day over a min $3000min (if your lucky) turbo or engine repair, im a diesel mechainc and cut my teeth on lambo/ duetz tractors- all prime movers/ tractors and excavators that i work on run with turbo timers and pyrometers again cheap insurance, i even have turbo timers fitted to kubota/ john deere diesel ride on mowers.
cheers

Hi Guys-
I was looking at turbo timers for my last car (turbo forester) when i upgraded the turbo to a turbo twice the size. I was talked out of a turbo timer then as the general concensus was that now turbo's are water cooled they are able to cool down very quickly and i used to just take it easy for the last few minutes driving and over 100,000K's with a turbo running 20PSI on bost never had a problem. I regulary had it so hot that this turbo would glow orange!

In saying all that i dont even know if the Prado turbo is water cooled or not- is there anything in the owners manual about letting the car idle for a few minutes after working the engine hard before switching off? I got into the habbit of just driving slowly for a few minutes and still do this for the Prado.
You may have something with the Prado turbo coming on boost MUCH earlier than the bigger turbo i had previously as it would not really hit until 3-4K rpm.

I changed my mind and removed my post. Curious why? Look there: http://www.pradopoint.com/showthread...upgrade-in-GXL

It's not just heat soak but letting the turbo run down from 100,000+ rpm when the oil supply is cut off to the bearings. I had turbo timers on all my past turbo diesels but haven't bothered with the 120 because the manual says to let it idle for 30 seconds (I think from memory) if you are stopping after a highway run and nothing if stopping from 60kph or less. Most places we go you have to drive for a few minutes at 60 or less before you stop so I don't bother. The only time I consciously let the engine run after stopping is when I come off the beach where the engine has worked in the soft sand. Or when I stop on the highway to check the trailer/load and usually I let the thing idle while I check. As for timers on naturally aspirated engines you are wasting your money. I have had quite a few diesel tractors over the years and have to say none have had molten pistons from stopping them too soon after running at optimum engine speed. Sorry I think turbo timers are a waste of time and money just remember to take it easy after some off roading or stopping on the highway. Oh and it is illegal in Qld too to leave your car with the engine running.

Also have a read of this thread http://www.pradopoint.com/showthread...r&daysprune=-1 the consensus is that modern diesel engines such as we have don't need them.

Plug and play turbo timers here http://www.newpro-tech.com.au/gallery1.htm

If you want one go for it. But in my experience take it steady in the last 2/3 blocks and it is all good to shut down.

They don't do a plug and play for the 150 Prado

I have read a lot of the reports that say we don’t need one, but I would like one. After giving the car a hard time going through mud or sand and having to stop due to a hold up in the convoy, I leave the engine running and then go back to turn it off a couple of minutes later to turn it off. A timer could automate it. To me it’s sensible.
