Looking for EGT data
I'm gathering data for an EGT database I'm putting together. I have some data already, but I'd like to get the widest possible cross section of real world data. This is what I'd like to get actual data on:
1. EGT's at idle
2. Infrared temp gun data of the headers right near the EGT probe location, that corresponds to that EGT data in #1 above
3. EGT data under light or moderate load, such as brisk highway cruising
4. WOT full power EGT data, such as at drag strip or dyno
If possible, please take an additional moment to include what the motor was, fuel used, and whether the motor was Naturally Aspirated or if a Blower, Turbo or Nitrous was in use.
Thanks for your input.

1250 idle
N/A infared
1350 cruise
1450-1500WOT
A/A intercooled, twin turbo, 350ci SBC, 8.5:1, 23 degree heads, 18-20psi boost, 93octane, SEFI.
the high EGTs are a result of rich A/F 11-11.5:1 and late ign timing.
if I tune it in the 12:1 range the temps will actually go down @WOT to around 1300. but at the risk of detonation from trying to burn koolaid, I keep it safe and rich.
a dyno operator I know says he sometimes sees 1600 with c16 on
max effort N/A drag engines. I'm sure he's speckling the plugs at this point.

Good info there, thanks
