Radiant heat

[Craig69]

Anyone ever wrap headers and pipes on a turbo car and radiant heat get worse?

Craig69,
I may have a theory on why radiant heat was elevated but before we go there..,


1. How thick is your wrap? 50% overlap?
2. Do you possess an infrared temp gun?
3. How are you measuring radiant heat?

(As a nuclear engineer, I have to address thermal insulation on a larger scale..,but please know this.., if you study heat transfer,
there is a point of insulation thickness where it actually increases radiant heat because of increased surface area to radiate with inadequate insulation factor.)

Sorry nobody has replied yet.

Please reply.

I wanna help

When I use to drag race imports I used thermal wrap and it cracked 4 different turbo manifolds. I tried stainless manifolds and mild steel, all wrapped using different overlap techniques and same results, they all cracked. I never used wrap again .

What I did that worked was hood venting. The difference wasn't dramatic but it was effective.
