I've noticed my turbo and manifold are getting really hot, what would cause this?

One of two things.
1.The hot exhaust gasses flowing through it from the engine.
2.From running a rich A/F.

It is not going to be cold.

Don't burn yourself...

Obviously, but I know it shouldn't be glowing RED hot.

Brolewigi · 01-27-2004, 01:50 PM

hmmm. Glowing red. Thats not good...
How much boost are you running?

yes, all turbos will glow red if boosted hard enough and long enough. for instance, a 50-120 highway pull will generally make them glow.

when i rape my turbo for a bit, it will start to glow red, its pretty cool looking in the mid-night after drifiting for a bit and seeing it glow.

gsracer · 01-27-2004, 02:51 PM

mine is doing that too after like a 1 - 3 hard pull, it will glow real red.

S13Koop · 01-27-2004, 03:06 PM

ok, i was getting a little worried,
although, is there a way I can get it to glow green or even an indiglo color?

Brolewigi · 01-27-2004, 03:12 PM

It's not a good thing to see that. But it happens.

A rich A/F runs cooler than a lean A/F. how come you're saying a rich A/F is causing the heat? The only thing that heats up under rich conditions is a catalytic converter.

Actually, EXCESSIVELY rich will heat things up too. But yes, lean = hot.

did i mention my downpipe is a little dented, probably restricting flow?
new one is on order as well as a test pipe from ProjectSilvia.com

Clogged exhaust will do this as well, or at least aid in making it happen.
