Thanks for the info Zate. I'm only concerned with adding power and reducing detonation. NOS and turbo timers are not part of my equation to meet that goal. I would love to go to water injection, but I'm not sure that ECUtek has added that to their maps.

What's wrong with a turbo timer? The oil has to cool if you run it hard. I fail to see what is wrong with the added conveniance of being able to walk away from your car instead of sitting there waiting, especially with how cheap they are.

oil and turbo technology has come along way since then. unless your bosting to a stop .. generally just finding a parking spot.. or puliing in and getting your mail.. or coasting through the traps.. or heading back to wait in line at a autoX is sufficient to cool the turbo back to its notmal operating temps.
TTs are just a gimmick in my opinion.. not needed at all.. if the car needed a TT i am positive subaru would have installed one (as would all the other turbo engine manufacturers) .. and i dont see one on any rally cars..
no one boosts hard and then shuts there engine off.. just doesnt happen.

btw.. saw the PERFECT water sparayernozzles at the state fair on the weekend on one of those outside cooling fans that spray water into the air stream (and its that exact principle that is used for cooling your intercooler) .. makes a very very fine atomized mist.. exactly what you want.. wont have time to drip anywhere because it will evaportate.. and its that phase c hange that gives the most cooling effect.

I think the main reason race cars dont use them ate is because the engine gets rebuilt after every race, I know on the audi my oil return line had to be replaced and I was doing mobile one synthetic every 3k miles on the nose, I mean for $90 I thinks its good insurance after having to replace 2 turbos on my audi. Coking does happen even with the most advanced oils and and water cooled turbos, and when you think how hot the oil gets specifically from the turbo and how vital it is for the turbo to work why even risk it, especially on a modified car, if your going to spend money on it, why not have that inch of safety there. Its not like its going to hurt anything by having it.
oh and on the S4's and TT's they dont have a turbo timer as such, but they do have an aux oil pump that will continue to pump oil through the turbos after the car is shut off until the ecu is satisfied that it is cool enough.

The heat contained in the turbo charger will begin to vaporize the coolant in the turbo charger after the engine is stopped. The hot vapor will enter the coolant reservoir tank, which is the highest point of the coolant system. At the same time that the vapor exits that turbo charger, coolant supplied from the right bank cylinder head flows in to the charger. This action cools the turbo charger down. This process will continue until the vaporizing action in the turbo charger has stopped or cooled down.

Ive always had a problem with that statement, mainly because its true it will cool the turbo, it doesn't address the problem of hot oil sitting in the oil return line and coking on the sides like plaque in an artery

i'll say it one more time.
new oil technology.
its an old thing that used to happen with F1 turbos way back in the day.. it happened to a few turbos on some older turbo cars.. but anything you have thses days will use modern oil.. and a modern cooling system (as luke posted above) and wont need a gay ass TT
theres a nuimber of articles around about it. one from autospeed where they ran a Experit turbo engine on a engine dyno until the whole turbo/exhaust manifold was redhot.. then shut it off.. no TT.. they did this a number of times with NO adverse results.

like I said it happened to me running mobile one synthetic oil changed twice within the recommended service intervals, so I wouldn't say new oil technology because the best oil technology still did it. And doing it 5 times isn't going to do anything, its a build up process, just like eating 1 bacon double cheeseburger isn't going to give you heart problems. and again if it wasn't needed why would factory cars come with the oil pump feature?
