hi all,ive recently ported my standard headers bought a decat 3" ss downpipe a solid uppipe and put a 99 intercooler on my 95wrx import,ive wrapped headers and up and down pipes,but when ive took it out for first time with these on, only round block,when i got back inlet manifold way hotter than before. wanted to know if this is normal when they av been wrapped?


cheers eddy.

 

Beggs the question, why did you wrap them in the first place then mate????


heat soak perhaps???

 

Was it in tin foil .....with KFC chicken in it ??

 

No it doesn't.

 

how doesnt it?


i think it was a valid point was it not?


Its simple enough, why do you wrap the exhaust manifolds, can we speak in english as well please, headers, are we all ****ing american now????

 

another thread ruined lol



this place really is going to the dogs

 

WTF??? You joined this very month FFS!!!

Nobody has asked why someone would wrap those parts. It was asked why he wrapped those parts. A question that was pretty much answered by his obvious concern that temperatures had risen instead of . . . . . . . .

 

who gives a **** when i joined you clown, i take it you were born into this BBS with 2,743 posts of crap.....


Why were the parts wrapped and temps rising a supprise???

 

The name says it all zyruss .....7Foot of bull$hit

 

He must have been the offspring of an elephant

 

 

I've heard of wrapping the downpipe, and maybe the up-pipe, not sure about the headers though. I believe the idea is to keep the exhaust gasses hotter, making them move faster, and to help limit heat soak, by keeping the heat in the pipes.

Possible with the headers wrapped, keeping the headers hotter, it might be making the exhaust exit from the heads hotter by conduction, in turn increasing the temp. of the whole engine including the inlet manifold. Try taking the wrap off the headers, and see if the inlet runs cooler or not.

Or maybe by only going around the block, your thermostat may not have fully opened, and therefore the cooling system would not have been at full efficiency? Try a proper run to see if things are any different.

 

thanks mate,at least someone got something useful to say i will try that see what happens,but some people have wrapped there headers on the project secion ov scooby net thats were the idea came from.

cheers eddy

 

EddySTI,

Robs answer aside, you'll be much better off posting in technical. I've got my headers / exhaust manifold, uppipe and downpipe wrapped FWIW, as have many others. Harvey's good on heat management and others will offer well considered, mature and knowledge based responses - which is what you want I guess.

yeh mate helpful opinions are what i was after but ive already posted in technical and no responce am afraid.thanks anyway.
