Turbo Timer

BHODGES3 · 05-29-2003, 05:08 AM

So did we ever settle the debate of whether you need to leave the car on a bit after running it? I thought I read on Subaru's site at some point saying that it did it automatically so you didn't have to leave the car on, but now I can't find that. Any ideas?

Good question. To my knowledge, you don't need to cool it down unless your were driving it under SEVER conditions. I think that you should probably just squirt it with the I/C spray...

I'll ask that question in July when I go to the ride and drive...

Sounds like something that would have to be listed in bold in the users manual. Any people with their STi have the booklet handy?

You shouldn't need a turbo timer unless you are running at the track and pull into the pits and kill it. The IC spray has nothing to do with the turbo and the possibility of frying the cooling oil....sorry murley!

I think as long as you give the car a decent cool down after really getting on her, you should be just fine without it. Modern turbo cars have designed around the problems of the first turbo cars....otherwise you'd still hear magazines and the like complaining about the reliability of turbo vehicles.

I believe the tubro is water cooled so it does not really need as long of a cool down like old school turbos did. I will still let her run a little after a hard run though.

CloNeGTS · 05-29-2003, 10:20 AM

Good point...forgot that part. Old turbos used engine oil for not only lubrication but cooling. But as MKIV mentioned, most of the cooling is done by the water. And from what SPD Tuning has mentioned, the water system is designed so that water continues to flow thru the turbo for several minutes after the engine has been shut down.

Anyone with their car handy care to check that out? I believe they mentioned there was a reservior that was at a higher elevation in the engine bay that allowed this.

Are you guys sure the turbo in STi is water cooled? I haven’t seen that anywhere...

Even if it is oil cooled, I don't think anyone ever proved that a turbo timer extends turbine life. I was going to get it initially for my EVO, but now I am leaning against it. I think I will just let make sure I don’t turn the engine off immediately after hard-core driving.

I'm gonna ask my Subie "Master Certified" mechanic real quick about the WRX's turbo. Hold on...

murley · 05-29-2003, 11:41 AM

Okay, just talked to Keith. He's the mechanic going to the STi R&D in July with me. He's been fixing Subies for like 13 or 14 years now. He said that the current WRX is at least oil cooled, and probably (without pulling one out to see) water cooled as well. Now, that's obviously not for the exhaust gases, that is air to air cooled. But for the turbo and turbine itself it's both, th thinks...

Btw, Murley I need to send you my avatar pack so you have some to pick from.

Well I used to have a 99 Passat 1.8 Turbo and after a simple drive down the freeway the turbo would be glowing a nice brite red. I think it was only oil cooled.
So why don't you just wait till you get the car, then take a 30 min trip down the freeway at full boost and pop the hood and see what color your turbo is 8)
