So, any idea why the #1 exhaust pipe got so hot? Was it just for break-in, or was it still doing it the next time you fired it up?

What were you doing with that box and wire near the end?

Dave,
That pipe is drilled for a EGT probe. So there was an open tiny hole allowing air in and burning unburned fuel in the pipe. Add to that, those carbs were inadequate for that motor so it was running lean. It wasn't a problem because the engine was on a stand and not under load.

Thats header always has an elevated EGT on #1. We have been seeing this for years on the dyno.

The box w/ wire was a Fluke meter with a temperature probe on it. I was checking the exhaust pipe voltage. (IMG:style_emoticons/default/shades.gif)

Cool, all of those make sense. Even McMark's answer, sort of. (IMG:style_emoticons/default/wink.gif)

Thanks for clearing that up.

Dave, I love that you understand us... But, no. Those answers don't make sense. You can come and hang with us at the OC anytime! (IMG:style_emoticons/default/biggrin.gif)

How could you tell the #1 pipe was hot with the #2 pipe glowing so brightly nearby? (IMG:style_emoticons/default/sunglasses.gif)

BTW, running that lean is a quick way to destroy the coating on a header.

Chris,
This is not your original coating. They were just re-coated at a Jet Hot facility here before being installed. Once the EFI is on, they will never run that hot again. After the 20 minutes, the header coating looks fine.

Here is another Original Customs application. This is something that Mark has done on a few EFI engine builds so it is tested and works. One of the parameters SDS uses to meter fuel is the temperature and thus, density of the intake air. This is the IAT or intake air temperature sensor. Mark has fabricated a mount that puts this between the air cleaners on the right side throttle bodies.
Next up, the linkage. A much better than hex bar solution!

Now that is a very accurate linkage set up. Mark had to source longer threaded rod to go between the pivot and the throttle body because this engine is so wide.
Nicely activated by this sexy little cable guide fabricated by Mark at the OC... I like it! (IMG:style_emoticons/default/biggrin.gif)
