Default Attn: DLC, Intercooler question

I looked at your Intercooler mod in your site, you removed the chimney leading to the turbo, is there a problem with turbo cooling for you? Was the AC hose on the way with the intercooler?

One more thing, I confirmed with a friend that on his 91 Legacy turbo, the AC hose(behind the chimney) shown is different than the 93 that the 91 is a straight metal hose. This hose may be on the way when installing any intercooler.

I'm still not sure if the chimney was more to cool the turbo than to keep the heat out of the rest of the engine bay, off the AC line, etc...the turbo has the oil and water to keep its important bits nice and warm while the rest will simply radiate. I had to take it off because it was in the way of the turbo-IC hose. I've seen no problems so far, even on very hot autocross days.

The IC line was in the way, so i stuck it back under the dogbone to get it out of the way. I'd like to see a picture of the 91 line and see how much more it could interfere.

The chimney is used to cool down the turbo while driving, i think one of your articles on your site says that and it's pretty obvious.

I will try to get a pic of his 91 setup, he's got WRX turbo bolt in and some kind of custom intercooler.

On a stock setup, perhaps. The scoop has the baffle that leads eventually to the chimney, and at speed i suppose that some pressure could build up over it enough to actually make a difference. Another article i have elsewhere states that the main purpose is to allow the heat to rise up through the hood at low speeds and while standing still.

The baffle is removed on the car right now, and i haven't made anything to restrict air so that it goes over the intercooler only. At the moment, it could be better cooled than before.

I've seen many cases where people will get the turbo housing ceramically coated, to prevent any heat from escaping into the engine bay. This would mean that all heat would have to escape from the exhaust, coolant or oil. In this case, external cooling seems unnecessary for the turbo...

I see, now I know what ceramic turbo refers to.

BTW, are you going to fix your car after the accident. Sorry to hear that happened.

Some guy pulled in front of me, and it tweaked the bumper a little and scratched it up. The hood looks ok, i think it's just pushed up a little, but might be bent ever so slightly. The corner lens has a spider crack in the middle, but shouldn't affect it. The headlight needs to be readjusted...

Let it be known that my front bumper has never been attached all that well. It seems to have been plowed into snowbanks or curbs a lot before i got it, as both sides weren't connected that well when i got it. It even had a bra on it originally, hiding some of this.

I might have a shop i know of make an estimate, get a check from the insurance company and just put it towards the loan instead of actually having it in a shop for x amount of time. It's my only vehicle, so you can probably understand my reluctance to fix something that's barely noticeable and doesn't affect the car's driving.

Dealer Xing: The ceramic you might have heard referenced before is the usage of ceramic materials in the turbine/compressor wheel, not necessarily an internal/external coating. I think Nissan put these in some Silvias in Japan. IIRC, they spun slower, but could take some serious heat.

or ceramic coated bearings which are often used in turbos
