header wrap

[slickrc]

i was going through some of the member's rides and description. i came upon this description..." headers with thermo wrap( bad, i know) "......i dont get it. is he trying to say that the header wrap is bad for the engine? i thought it was good....please reply

[XINSANEJDMX]

whats the point of the wrap?

[JoshM]

Pros = keeps engine temps down
Cons = may crack header over time

[baracuda]

maybe he was reffering to how well he wrapped it. maybe he did a shit job so it doesnt look too good.

[XINSANEJDMX]

so the engine cool down faster with the wrap?

The engine bay temp stays down thanks to the wrap. It keeps the heat from the header in the header itself.




For example... turn your heat way high in your house. Place your hand over the vent. Then place a towel over the vent and place your hand in the same area. It won't be as hot.

oh i understand

[baracuda]

oh i understand

its def worth the 50 bucks. i have it installed and LOVE IT!!!

It also frees up a small amount of power. Keeping the hot gases from cooling in the header reduces turbulence, promotes flow and that helps the engine breath better.

Be aware that header cracking can occur from the increased internal temp of the header after wrapping it. It seems to be luck of the draw, even with quality DC sports headers, as to whether the welds end up breaking or not. It may happen in one month, it may take two years, but it usually does happen.

Here's a thread about my DC header failing: THREAD

Wrap at your own risk is what I always tell people. I've heard horror stories of the header melting and/or cracking, but I have never experienced it, nor has my dad on all of his cars over the years.

If done correctly you wont have any problems (like several of the members have already said). I applied a thermal coating to my header before applying the wrap just to prevent any possible rusting from happening. It's been like that for quite a while now and NO issues have cropped up.

the best reason

it makes your A/C cooler


con- if white, when dirty it looks like shit

has anyone thought about wrapping the bisi header? do you think his construction would hold up, or just not even risk it

I wouldn't risk it. Maybe some coating, but definitely not wrapped.

Yeah, if you were to buy a Bisi header for another 150 bones they heat treat the whole thing. Also Bisi says that when using header wrap, due to the high temps the wrap deteriorates the welds on the manifold.
