What To And Not To Insulate (under the hood), That Is The Question!
Brothers,
As I look at the pictures posted by many, I see different insulation methods under the hood. I see a lot of added insulation on "stuff". What things should be insulated? What things like to be hot (probably nothing)? What things like to be cold (yes, I know intake air)?
Thanks,
John

the big guys will direct you the right direction, bt i would protect hoses and cables from anything hot like the manifold heads etc. plus you dont want hoses rubbing agains nothing.

Some folks put a lot of insulation in there because they don't like the noise of the engine. I don't see a need for much insulation from a functional standpoint. I took the blanket off the inside of my hood cause it was torn and sagging and would get caught in the fan. It was a real PITA.

John, what is prompting your question? I've used starter insulation over my glow plug and throttle cables/wires under the turbo to protect them from the heat. Otherwise, no hood blanket and everything is nude.

Mel,
Just looking at pictures and seeing guys doing different stuff with insulation. Is any or it of any real value?

P.S.- Sitting here Sat. A.M. and it's looking too wet for a visit to Gettysburg. What I really wanted to do was look under everyones hood. Looks too wet to "hang out under the hood". Plan B = replacement power steering pump, after all "She Leaks Everywhere".

I would think all electronics and wires and hoses should be insulated from the heat of the manifolds and stuff. But also I would think about trying to insulated the manifolds and exhaust flow to the turbo so that the heat inside the pipes is as hot as it can be and that way it should flow faster and add more power to the turbo. Also try and keep the intake side of the turbo insulated away from the heated side so that the intake charge is as cold and as dense as can be. I have thought about trying to make an open element system but with a heat shield around it like how you see on the cold air kits and stuff. Maybe use some of the manifold wrap stuff or get them ceramic coated or something so that the heat stays where it belongs in the pipes where it can do some good and not outside of the pipes where it can cause some damage. Oh yea and I am all for ditching the sound deadening on the hood, gotta have that diesel clatter [img]/ubbthreads/images/graemlins/smile.gif[/img] and the turbo whistle [img]/ubbthreads/images/graemlins/cool.gif[/img] just my 2 cents
