E-85 Exhaust color question

The inside of the whole header is always stained red for me.
This is the header I run now,

This is the one from a few years back,


I don't quite understand it, the fuel is clear.

These headers have had many dozens of red hot cycles, maybe that has something to do with it. It's 304 stainless tubing.

Another pic,

The red is Iron Oxide. Formalide is what is produced. It atacks steal. They need to be aluminized inside coated.

God only knows I am all for good consructive debate, but gerdone, your in lala land. Get it together.
Here is the chemical makeup of formaldehyde. See any iron in this? Formaldehyde is a very very minor byproduct of burning ethonal.
What is causing the RED again, where is the iron oxides coming from again. Jockorace hit this on the head. You need to give some thought before posting.
Now, I am giving you your chance. Tell us where the iron oxides are coming from. If you can't, or you wrong, your going to take one more ding in you flawless reputation here. Again!



Where did the red come from. I am going to guess from the same place the yellow comes from in my engine. But then, I run a saffron oil. They must have made Unchained's E85 from sugar beets.

At what compression ratio N/A do you think E-85 has an advantage over something like C-12 ? It at all other than price.

Under boost in a blow-thru application will the E-85 have a huge advantage other than just price?

From what I have been able to gather from Maxi, and the posts Unchained has made, the biggest gains are from boosted applications and the latent heat thing. Unchained removed his innercooler. the blowthru gys never had them, and they are both able to run pretty good boost numbers without them. I think Unchained could still benefit from a cooler if he wished to raise the boost. But he is making som much HP now, why bother with the extra weight and compexity. And I not 100% sure he would see that much. He would certainly have to push the turbo harder to overcome the coolers retriction to get the same boost back, and even harder to make even more. I doubt he would see anything at all at the same manifold pressure. And he is seeing some pretty high manifold temps BEORE the injectors. So the cooling effect must be working or he would be detonating big time.

Over C12? I doubt they can make more power. Its big attracktion isn't all power. Its price and availability. We have had this discussion in the GN class about allowing it. Some think that the stuff will create runaway speeds. Many of us say BS. Not over c16. some of us have learned the limits of C16, and its more than many think. But, you do have to run the cooler.

If they allowed it in the GN class, would I run it? I don't know. But I sure as hell would play with the stuff. But if I couldn't make the power, I would go back to the C16. Winning cost money. Not doing it to save money that for sure. Its never going to make more power because it is ethonal. Anyone that thinks that is way wrong. But in the GN class, we have a limited blower speed. If I could take out the cooler, and pickup some boost, it could possibly make at least the same power as C16. And you would have to be crazy not to run it.

You will never see the stuff in NHRA ProStock. Even if they allowed it tomorrow.

Good point, I'm going to have to look into replacing it in another 25 years or so.

Same color as when running octane boost, never a problem.
