Turbo timers

[David]

As this is another topic we all should be interested in I thought I would start a forum.
I am looking for people with first hand knowledge of solutions that worked for them.
Prices and features vary, I would be interested in the most unobtrusive and elegant solution (with pictures).

Thanks again to all

Hi,

Good thread, it's a low priority right now for me but I would definitely like to look into it further. The only system I have been quoted on also included a pryro unit and cost about the same as my second Delica's purchase price.

if you are looking for a bit more power you can boost your turbo up to 14-15 psi. Its relatively easy to do. There are alot of threads on doing this on the uk site. I did mine and it helps out a bit

I'm skeptical they are necessary in something like a delica. The only time it is necessary to let your turbo cool down is if you have been running hard on a highway or up a hill, and then a few minutes idle will do the trick. Driving sedately around town (which is pretty much all you can do in a Delica .. not exactly a sportscar) they are absolutely un-necessary IMO. The odd time I have been doing a hill climb I just take the few minutes to let it cool down.

Be aware that by increasing your boost you increase your firing pressure/temp and engine wear."the light that burns twice as bright burns half as long"

Yes this will happen .....However if you take a few steps to reduce heat, like bigger exaust (removes TONS of heat) install an intercooler (also does the trick) or a free flow air filter with a cold intake. These simple steps will dramatically reduce heat stress on your eingne, and will give you way better fuel mileage and a bit more power.....good luck

Mine came with a turbo timer, I'll say its very handy. Even two minutes is a bit of time to sit and, well, wait. In that time I usually make it into my house, and get my shoes and coat off, and say hi to me wife, and I still hear it purrrrrin away. I've also found it nice, since I can't do drive thru in teh morning, I set the timer to 5 mins to keep the van toasty while I run into timmy's. All in all, I'd say its one of those things you can live without, but its very, very nice to have.

Useful if running on WVO as it allows you to better purge your system.

Allright for cooling the turbo but if mine didn't come with one I wouldn't have bothered. I'd save my money for something more useful (Pyro...) and simply drive it easy on the last few Km and let it idle while I remove seatbelt, stereo, add the club, get out...

Where it's really nice to have is on a cold morning. I start my van, set it for 5 min and go back inside while it warms up. No one can steal it as there's no key and won't engage in Drive. I usualy make it back before it shuts off and it's already warmer...

I have a manual turbo timer.

This is not entirely true.

Additional boost will actually cool the engine and drop combustion temperatures as long as more fuel is not added. The only time you're going to get a rise in temperature is when there is more fuel added or there was excess fuel to begin with. Additional boost will cause more efficient combustion and reduce smoking (more power) as long as you're not turning up the fuel.

As for a turbo timer... not really needed. The only time you might want to idle for a minute or two is when you've done a hard run on the highway and don't do any slower speed driving before shutdown. You might encounter this kind of situation when you're on a main highway and pull into a filling station. In that case, just sit at the pump and idle for a minute or so while you get organized to put the fuel in.

I understand what you are saying this info is delica specific, so a small boost increase may lower egt readings as unburnt fuel isn't combusting in the exhaust manifold, and that would in turn wouldn't heat the air being pulled through the turbo as much. on the flip side doesn't compressing air add heat, and additional boost without additional fuel caused a lean condition, which also creats heat?

Just so people don't think that simply upping the boost means your ride will run cooler, it does quite the opposite if your vehicle doesn't run slightly rich to begin with.

I've got a EGT gauge (aka pyro), and let it idle until temp drops below 500 F (somewhat arbitrary temp). Normally, by the time I'm in my driveway it is that low. But if I come off the highway at a filling station, it can easily be 5 minutes before it has cooled down enough. That is, if the highway was uphill. If it was a long downhill to the stop, the temp can be down around 300 F even at 100km/h

Pyro is definitely a good thing to have. Will help the turbo last longer, especially the pre-93s without the water cooling.

Now a turbo timer that tied into the pyro to shut it off at a set temperature would be useful, a set time I think isn't very useful. Considering that the last weeks, crawling in gridlocked traffic at -20 the pyro never even got over 500F, I don't need a timer. Other times it would be nice, but only if I could specify the time.

[Chewy]

you can specify the time on every turbo timer I've ever seen, and it's a one button touch override to shut it down. Set the timer to run for 2-3 minutes (well enough time to cool the turbo from any reasonable temperature).

[Erebus]

I meant specify the time when I'm shutting down. Such as 1 button for 2 minutes, 1 for 4, one for 6. Going into its "setup" mode to change it I suspect isn't that easy. But then, I've never had one. I just let it idle while getting my junk together, then shut it down.

[Chewy]

sorry, I wasn't trying to be a jerk ( hard to get your tone across on the intrawebs). The time is easily changed, usually in 10 second increments, but sometimes just minutes with 1 button (usually no setup mode unless you have one that reads water temps and speed etc. and even then, quite simple). In any case, just idling it down like you said works just fine. Just some insight for those considering.
