That being said I genuinely hope that you prove them wrong

Both very valid points that I hope to have addressed. I both did my best to lay down a reasonable and even wrapping while trying to prevent uneven expansion especially around welds near the flanges. Without a thermal gun who knows how well I did though.

Also, the Swaintech white lightning coating is baked on at many thousands of degrees and rated to about 3000 F. I doubt the measly 1800F I see on the track will affect this coating.

Literature:

And if all of this fails, I've got the good old stock manifold in a box

EDIT: Did you contact swaintech concerning wraps and their White Lightning coating?

Well, wrap is pretty damned easy to install in the scheme of things. Since I now have a sense of how well wrap retains heat, I might just tear it off tomorrow and take a better look at the EGTs with just the ceramic coating.

Yes, I should have take better notes prior to the wrap.

Will also call swaintech tomorrow.

Yes, I saw lots of conflicting articles on the net.
