Red Hot Manifold?

[oneoffaccord]

Ok last night me and my friend were messing with the setting for the safc. got the car running better. still need to fine tune it though with the wide band. so we look and theres smoke from the front (turbo area) the manifold was glowing cherry red. it was just a small section. right before it merges to the wastegate flange but that wasnt cherry red. it was just a section of at least 2 inches to 4 to most. it was so hot the return line melted away. is there a reason why it did that? why only that spot and nothing anywhere else? where can i fine a stainless steel return line at?

Could it be making that much heat because it's running lean?

sounds like either your timing is way off, or your running lean....

can i ask though, with the abundance of information about boost on this site, why are you using an AFC for tuning? it might be advancing your timing (sorry, it IS advancing your timing), causing excessive heat

hence the predetonation larry...


wanna borrow my chip burner?? hehehe...

what manifold?

[oneoffaccord]

this the manifold that im running. right where the wastegate flange is thats where it was cherry red hot. im talking to a friend of mine that knows alot about turbos and tuning. he straigt told me to use the afc and not use a chipped ecu. ive done my research alot on this. on the air/fuel ratio guages its running between lean and stoich. more towards stoich. on the afc its running 14.8%a/f ratio.

your friend is smart. will he be my friend too?

hahahahahaahah!! its stoich under boost? please tell me its not stoich under boost.

Stoich while in boost? Now that is something I would love to see a Honda do! Hell some factory turbo'ed cars don't even do that! Lets not jump the gun tho. Does he mean while going WOT? If so, tell him to stop touching your car.

yeah lol. new evos come down to 10:1 AF close to redline

If your running turbo rich would be on the safe side. As mentioned stoich WOT is just bad lol bad things WILL happen. You sure your using the AFC right? Best way to use it is on a dyno but that costs money and every setup is diff.

Is it because this thread can quickly turn into, "Why did my engine blow to bits and pieces?"

that, and the manifolds design could cause this. If the gases are literally getting trapped around the inlet for the wastegate and then being pushed down by the collected gases coming from the head it could be a matter of inferior design. The top mount is cool, but its benefits come from the collector...that mani he has looks like a logstyle with a penis to me.

Leave it to Antoine to study the whole picture. I couldn't get past the stoich thing. I told Jose if he could find a stock turbo'ed car that runs stoich at WOT, I would get a Kia within the hour.
