Glowing red. [Merged 1-7] Exhaust, turbo, glow, hot

[Goblin]

I know that if you drive a TSI hard and pull over and look at the turbo at night it will be glowing red and that is normal.

but...

If you are driving a TSI grandma style and pull over and look under the hood DURING THE DAY and the turbo is glowing red is that a bad thing?

If so what possibly could be wrong with it?

 

[Burnett03]

after a run at night i notice that my mani glows red. I can only see it glowing in complete darkness so it isnt too extreme as opposed to it glowing bright red in daytime, which doenst happen. I need a egt so i can tell my temps but do others notice their mani glowing?

yes its normal.. another reason to turbo time the car

 

[240kid]

yea i def use a turbo timer. Call me crazy but a little bit before I park I will pop the hood to get a little extra air in there and when I park i always open up the hood for about 10-20 seconds. Its just a habit, I am sure it would be fine just sitting there with the hood closed but whatever.

 

[blcknspo0ln]

BWAhah.. I do that too, but only when I'm home.

turbo and mani glowing is normal

 

[Talesin]

Yep. Usually after a long pull, it's glowing nice and bright, so long as you park in a shady spot, even during the day. I'm probably running really rich though. It's a nice touch to get out and light a cigarette off your manifold or turbo exhaust housing, if you're a smoker.

First off i want to say that i just did a head gasket repacement and did the timming belt. got all that done put in a ported intake manifold and 1g tb. got all this done and i kept the stock fpr on and ran the car and it ran fine.


Ok so i got my new areomotive fpr installed with steelbraided lines. When i took it out for a good 10min hard run my exhaust manifold was glowing and my coolent was boiling. I had the pressure set at 45psi with the vaccume off.

does anyone have any clue what my damn problem is? The car has been sitting for about a month getting all this stuff slowly done. getting ready to sell my shitty dsm.

by the way:

i change the thermostat, the cap, new coolent, so please dont tell me its any of that garbage. i think the problem lies in the fuel bc ive never ran my manifold to get it glowing.


thanks

dan

 

[gsxkid]

from my experience the exhaust manifold is always supposed to glow like that. But you might wanna get someone with more knowledge to reply

 

[99gst_racer]

I had the pressure set at 45psi with the vaccume off.

Did you drive the car with the vacuum line disconnected? Or did you reconnect it? Be honest.

 

[CanadianTSi]

Fuel pressure is supposed to be 43 BTW.

 

[dpbgst13]

ya i know its supose to be 43psi. and i diffently connected the line again. im not that retarted. But i just got back from another run and my intake temps got up to 122 and my coolent temps got to 240 by the time i got home. i was only out for about 5 min. ive never seen my intake temps that high. and yes i know thats terrible for the car but all eclipse are pieces of @#$@#$@!!!! Im about to take it to a shop. need more help.

also i was only boost 12lbs then it dropped to 10lbs but i know thats bc i have a boost leak in one of my piping connecters.

any advice before i take it in.

thanks dan

Well if you have a Boost leak you are definilty running very rich. Probably rich enough that you are shooting flames into the manifold on the exhaust stroke which is causing you very high manifold temps. It is probably also somewhat responsible for your coolant temps as well. If you are seeing 240* coolant temps that is the reason your intake temps are so high. The air coming off the radiator is going to be very hot and that is what is getting sucked into your intake. Fix your boost leaks and then come back and tell us if you are runnig better.

You got cooling issues man!!! Sounds like you didn't do the HG good enough. Very possible you are blowing all your coolant into the overflow bottle. Here is what you do. Let the car cool off. Fill the radiator with coolant. Take the car for a drive. Go and make full boost for a good 3rd gear pull. Come home. Check the overflow bottle. It should have some coolant in it, but not be full. Let the car cool off again, and then try to add more coolant. If you can add a lot, or have a lot of coolant in the overflow bottle, you got a bad HG (meaning you didn't prep the head/block properly) and are leaking coolant into the passages.

Its normal for the manifold to glow after a hard run. If it bothers you that much install the heat shield. Coolant doesnt run through the exhaust manifold so its highly unlikely that a cooling issue exists. In order to cool your manifold with a rich condition (if its even possible) you'd have liquid fuel spilling out of the muffler.

 

[dpbgst13]

alright I'm going to fix the boost leak. See what that does. but i think my head gasket is fine because before it was shooting out of the reserve tank but this time it was not doing that and i don't have any carbons in my coolent. It was just in the radiator itself. So I'm going to pick up some connectors and see if that helps. Before the install of the head gasket i saw the hole but it was jammed up against the wall but now its open to full air. ill keep you updated.

thanks for the info.

i finally got it after working for two days strait.

hooked up another slimline fan and ran it to the battery. Also i had them pulling instead of pushing.

also fixed the boost leak some what. still leaking very little from somewhere else.

thanks for all the help dan

Coolant temps of 240 deg. are totally normal. No cooling issues there at all.

They are supposed to be pulling instead of pushing......

In relation to the glowing is what I was referring to. I've gotten my manifold to glow and engine temps were 190 degrees.

 

[NOSLO2PT0]

Coolant temps and glowing manifolds are 100% unrelated. Kinda like saying my battery voltage was 13.2V, but the air pressure in my tires is only 32psi. One has nothing to do with the other.

I believe thats what I said. First time I've heard an echo that replies back with what I say but in a different way.

 

[Talesin]

Chiming in. Yes, I get the turbo glow too. It's nothing to worry about; make sure your 1G exhaust manifold is replaced with a trimmed 2G, and it'll get rid of the cracking problem.

As for my tone of glow, I tend to get the bottom-left on Defiant's collage after a good hard run on a five-mile uphill course (around five minutes), boosting all the way. Takes between five and seven minutes to stop glowing... which is why I bought a turbo timer. The glow is nothing to worry about. In fact, it can be very helpful if you're a smoker, and gets you SUCH dirty looks.

 

[TargeT]

I've driven many N/A vehicles, and none have had glowing headers or manifolds after long casual drives on the freeway. I contribute the glowing to turbos doing it so frequently is because the exhaust is kept around longer in that general area before its allowed to leave out the tail pipe. Contributing to longer amounts of time of heat being in one general area and not because of a horendious tune.

He can be taught!

Your right, the reason turbo vehicles glow is the same reason turbo vehicles have a nice deep exhaust note (when compared in both cases to N/A 4cyls of like displacement)

The Turbo is a big exhaust/heat restriction, which also restricts noise (giving our exhaust that nice deep note) a glowing exhaust manifold/turbo is, again, perfectly normal & is not something to worry about.

Take a good, hard pull up the Grapevine and you'll find N/A manifolds glow nicely, too. And even more if they're tubular or welded-up headers.

 

[knighteclipse1]

my eclipse is my third car with a turbo, my first cars were both Merkur XR4Ti's, totally loved them, but they are so dated now...well anyways, just to put my .02 worth in...both Merkur's always seemed to have glowing manifolds and turbos, never caused a problem. Just something I came to expect from turbo motors. The first time I saw it, I will admit, was quite scary. I have yet to see my current car have that happen, but it is something I wouldn't be surprised to see.

 

[Morel]

So you are using a shitty MHI turbo as you declaritive proof of your initial statement? Isn't that kind of like losing your virginity to a 400 pound transexual hooker and then declaring that sex really sucks as a known fact?

Oh..

My..

GAWD!


I laughed so hard I started choking at work thanks to you. Now everyones lookin at me weird.
