    Headers glowing red at full throttle, please help.

    I don't know if I'm running too much timing, or if I've got a mechanical problem, but on the dyno yesterday, all of my primaries started glowing red at high RPM during a pull. According to the dyno wideband, and my own previously on the street, the car is at 12.5: the entire pull within less than 0.1 AFR, and I'm running 25 degrees of advance until 5K RPM then 24 degrees until I finish the pull. I occasionally see 1 degree of spark retard, but usually none.

    It's a stock bottom end LS3, 226/234 0.600/0.600 114 LSA with 4 degrees of advance, ported heads, Kooks 1.875 primaries, 3" duals, no cats, FAST 102 with a NW102mm throttle body 2010 Camaro.

    Here's a video of it on the dyno. Right around 27-28 seconds in you'll see what I mean.

    Am I running too much timing? I can back it off to stock, which would be 2-3 degrees less. I also noticed the stock 2010 Camaro file has the AFR correction table adding spark in PE, so I'm generally 2-2.5 degrees higher advance than my main spark tables say I am.

    less timing actually makes the exhaust hotter, glowing headers is pretty normal especially if at night or lower light conditions.

    Reminds me of watching a blown C6Z on the dyno when it was night time... Watching form underneath, you could see the exhaust turn red up front and work it's way back as the pull progressed. Lol.



    My old turbo Eclipse used to generate so much heat in the manifold that when you parked the car, you could almost read a book from the red glow it gave off.

    If anyone cares...here's the dyno chart, blue is this setup, red was last year when the car just had bolt ons. I love how it lost NOTHING down low, and is able to carry the power so much further. The car is so much fun to drive.
