Just as the title states....I noticed tonight while hood was up car idleing for less than 5mins....the 5,6,7,8 are glowing red I never noticed that before...could there be a problem...Thanks

Mods are bolt ons with Maggie cam stall

was it just after some very hard driving?

what type of headers, CATs, and how much boost are you running.

Headers get dang hot and add allot of under hood heat. Common for them to glow. You just notice more in the dark if the hood is up.

hapisok · 10-11-2012, 06:15 AM

do you monitor your AFR? the rear cylinders generally run leaner than the fronts, just wondering if too lean can cause this condition and therefore your headers are running hotter.

BowenSS1 · 10-11-2012, 07:31 AM

There was no hard driving before hand.. it hadn't even been turned on all day....
Im running big flow exhaust 1 7/8 headers,no cats ,9LBS boost.
I do not have a/f gauge or boost gauge
I just thought it was strange to get that hot in less than 5 mins ...
Hell it melted the plastic protector over the Maggie water line on passenger side.

CyberPredator · 10-11-2012, 11:52 AM

maybe some sort of blockage although I don't know what it could be since there are no cats. Pretty odd for them to glow without being ran hard

Cam dumping lots of raw fuel in the exhaust at idle, burning off in the headers? Do your eyes burn from the exhaust?

Gauges would deff be my next mod

MA2010SS · 10-11-2012, 12:39 PM

What causes that is (1) a lean fuel mixture, (2) timing retarded too far at idle or a combo of both. Usually I have seen one side or the other glowing red, but never 2 cylinders on one side and 2 on the other side. Basically what's happening is there is not enough fuel in the chamber to cool it when it's lean or the timing is too far retarded and then combustion is happening too late and raw fuel gets pumped out the exhaust. Let us know what you find

BowenSS1 · 10-11-2012, 07:13 PM

Called tuner they said drive car around then park and pop hood and check
If they are red.... well I did.....car runs great when i get home i leave car running pop hood
And headers are fine....but once it starts lopeing they turn red again....
so i will let them know Fri. See what they say...??

MA2010SS · 10-11-2012, 08:46 PM

Another thing to check is to use an IR meter, one that goes up to 1000 deg F. I am running a whipple and across the board my header temps at idle are between 425 and 470deg on all eight cylinders, check the temp at all pipes

Lean

I think every aftermarket supercharged car needs an AFR gage on a wideband O2. Without being able to monitor that AFR everybody is just guessing. I'd get it back to the tuner, work on the tuning, and install an AFR gage.
