Heat Wrap Manifold? good/bad???

[deanomx206]

just bought a GMC Manifold off a user on here...
what are the pros & cons of having it heatwrapped?
also where can i buy the material from and is it easy to fit?:drink:

as said theres so many threads on this subject.

basically reduces engine bay temps and allows the exhaust gas, to flow out quicker

[deanomx206]

any idea how much id need? to do one manifold?

[jablitt]

useful in the saxo engine bay because the manifold sits bang in the middle (almost). its also near to most peoples cold air feeds and air filters = heat soak. helps to prevent the engine bay getting too hot. plus draws hot air through the system.

Pros:
Reduces engine bay temps, meaning car runs cooler.
Colder inlet temps, denser air, more oxygen.
Air flows quicker out the exhaust, meaning more can be drawn in quicker.

Cons:
Can crack mild steel manifolds.
Can be a bitch to fit lol.

whats the best stuff to get?
will 2" by 10metres be long enough? im guessing it would be enough to do the one 4 branch?
cheers

[deanomx206]

been looking on ebay and somewhere local sells it quite cheap
they do it in different colours
now i wouldnt mind the black one as i rekon white would get mucky real quick!
but obviously black attracts heat so i was just wondering wether it will matter what colour i use?
cheers

your worried that heat wrap will get dirty oh dear lol

anyway black wrap will eventually turn faded, it happened to my graphite coated one

[deanomx206]

so you rekon dont get black? will it make anydifference about the heat factor? thats my main concern!
i may go for silver then

[Predator_R32]

nah mate it wont wrap is wrap tbh

keeps engine temps down a bit, improves gas's flow and with temps down colder air :)

if you really want to push the boat out get the manifold ceramic coated

i have 30metres of heatwrap for sale £15 posted!!

No black doesn't attract heat but absorbs light, and thus heat, it can't absorb heat alone.

In an engine bay as it's dark, a lighter or darker heat wrap will make zero difference.
