Turbo blanket/Wrap recommendations

[imalumberjack]

Thought I would weigh in on this subject, my reply will have nothing to do with an ISX engine or any other diesel engine, it has to do with a theory by Smokey Yunick who was a very famous race car engine builder. His theory was that super heated exhaust traveled faster. What he would do is use an asbestos wrap to wrap the first 4-5 feet of an exhaust manifold in order to move the exhaust out quicker, I just read an article the other day that upheld Smokey's theory. I have wrapped a Cat engine several times based on Smokey's theory that I learned 40 years ago .....I could not give you any performance figures or even say that I know it works ...I felt that it did as I will do almost anything for a few more ponies. I never wrapped a turbo tho.
