2004 Disco 2 Engine Rebuild

Only marginal temperature improvements after adding reflective barrier to the air intake system. Not sure 10-15 degree difference will make any noticeable difference in fuel economy or power. I'll keep an eye on if and see if anything else comes of it.
Tested at 79 F ambient.

Yeah I wasn’t going to do the hold system until I shot the temps and found the temps of the airbox and upstream tubing was reading about 150 degrees so I thought I better do the whole thing to get any benefit.

Thanks @Sixpack577 for the comment! It prompted me to do a bit more research. I found this posting which seemed like a good explanation of the relationship between temperature & horsepower. https://www.superchargerforums.com/t...orsepower.597/
Kinda like 212 degrees f is boiling...where as 211 degrees f is just really hot.
Thanks for posting pictures and your results too, good stuff!

I noticed in the RAVE that there is a Gulf package for the middle east that has heat shields for the intake system. It looks like it is a radiant barrier with space between it and the intake hose. I'm wondering if that is more efficient than a radiant barrier applied directly to the intake components. I was testing my intake temps last night and could only get them down to 10 degrees above ambient after running about 80 mph for about 30 mins. It looks like there is a lot of residual heat that has to be blown out. I think this is a good argument for both the radiant barrier and a snorkel.
CVHyatt, what kind of radiant barrier did you use on the roof?
