[urq] How much heat is generated by our engines...just a rough is good...

[quattrodude at comcast.net]

I'm in the process of wanting to ceramic coat various parts of the exhaust and intake sides and wanted to see if anyone had any rough ideas about how much heat is generated at max boost on a slightly modded WX.

Im running in theory about 15psi (what was original stock setup, just chipped), when done I will be running I hope about the same boost, but with a larger intercooler and K24/26 hybrid for better low end boost and more efficient turbo over all...


from what I have read, 2000 degree is the max most of the good ceramic coatings can handle. 1300 on the low side for silver and shiny coats...and some places will not coat the inside of the manifold due to possible flaking?? 

I do not intend to replace the manifold with a header as then I would have to do WAY more stuff like EFI etc...but am open to other options...I know there is a 2 pc manifold but peeps seem to want about $4-500 for them and from reading the info on this list...for the small gain, prob not worth it.

Thanks for any help in advance?
