Turbo Timer

[SillySora]

Hey guys Pretty new on this site.

Got a MY08 Spec B

The Trouble i am having is when ever i use my turbo timer and then go to use the car again my dash computer goes berserk flashing lights ect.

Can't use Cruise Control or switch it into sports sharp mode.
But i turn the car on off ect a few times or hours and will work as per usually.

So atm i'm not using it and would like to see if anyone else is having this problem.

Cheers Guys...

First question is, why do you want a turbo timer? All Subarus post 2000 don't require a turbo timer for the turbo to cool down as it is water cooled (and the water continues flowing) even when the car is off.

Hey Silly SORA - Intro buddy

and Welcome.

Welcome Silly Sora

As mentioned you dont need a turbo timer so ditch it and your problem is solved.

there water cooled? really??????

i thought if u have a water cooler for the turbo there is no need for the TMIC? or am i wrong lol

Hey Silly, welcome to the site! Firstly, congrats on owning an MY08! Nice.

Secondly, can you let us know who installed the turbo timer for you? Considering installing just a turbo timer and cruise control and the in-dash computer goes nuts means quite a dodgy install job and if it's a shop it should be avoided.

The intercooler is there to cool/absorb heat from the compressed intake air. Water cooling for a turbo would be used to keep temperatures on the exhaust turbine side down in order to prevent overheating of the turbine and housing components. Well at least that is my understanding

In short, yes, the intercooler (whether top mount or front mount) is certainly beneficial

There is a big difference in the water cooling of the turbo housing/bearings and intercooling the air. I understand that the turbo has a water jacket which I would assume is connected to the engine cooling system. When you turn off the engine, the water pump stops, but the heat of the turbo, and the engine can result in coolant continuing to circulate for some time. The water jacket also helps to maintain thermal stabilisation - ie reduces shock cooling. The older cars didn't have this and when you shut down the engine, there could be issues with shock cooling and also heat soaking of any oil still in the bearings.

Just ask any pilot about shock cooling of air cooled engines....

An intercooler is a heat exchanger. Some use air, some use fluid. I believe that some of the older Legacy turbos used an air to fluid intercooler. The new models use air to air. They all have their pros and cons and I'm sure there was logic for changing.

As per usual, I don't guarantee the accuracy of anything have written, but I hope it helps.

Hey thanks guys i think it is a simple forward thing as you said.

Fair enought about the Turbo , going to get a avo one soon anyways.

It was Mercuary but they are pretty good too me and the seem to know a bit. So the Turbo Timer shouldn't be a Drama Anyways. But Just get them to check it out again.

It also helps if you give the engine a chance to cool down. ie. don't fang it for the last 5min of your drive.

Hey SillySora,

The issues you are having are because the turbo timer is only connected to one of the two power circuits. When the timer starts it needs to power both of these power circuits otherwise the computer cracks it. Hope this helps.

Thanks heaps man will check out soon enough.

Thanks for explaining the water cooling and intercooler difference to me, much appreciated
