Should i heat wrap my manifold??

[Josh_Phipps]

Can people give there opinions??? Ive got a 4-2-1 manifodl

Ive been told it can cause damage doing this but also help ur car as reducing heat n stuff in the engine bay?

[williamsvts]

it wont cause damage.
the people that say that have never done it.
i would say do it :)

[ad_vts]

its good so i hear

[Josh_Phipps]

How does it improve it though by doing it and where can i pick some wrap up from??

[CampDavid]

I'd do it. My milteck is heat wrapped and it melts enough stuff as it is. Be a nightmare if it wasn't

[CampDavid]

Also, have a go at doing ti yourself, its easy if you take your time

[stevenet15]

i have never done it but a few of my mates have and 2 out of 3 of them got cracked heads on the exhaust side due to the added heat retained from the wrap. mind you they had cast iron manifold and it not recommended to wrap cast iron maifolds as they are well know to crack when heat is retained, i personaly say if u got an after market manifold e.g stainless stell then wrap it but if u got a stock cast iron manifold wrapign it may cause cracking so i wouldnt bother. Anyway the way wraping helps performance is the heat wrap holds the heat in the manifold makign the exhuast gasses hotter which aids better gas flow and reduce the radiated heat in the engine bay

[CampDavid]

^ What he said, though a 4-2-1 will be stainsell steel

[williamsvts]

or mild steel.
its stops the gasses loosing there energy in the form of heat, therefore keeping them moving faster out of the head. this is called the scavange effect.

williams, you had your remap?

[Josh_Phipps]

Yea mines s/s so i think im gunna go ahead with it, Anyone know where i can get some wrap from lol, and is it best to wet it then apply it to it gets tighter when dry?

[bullit]

yes wet mate. if you scroll down and click on ax beefy thread he has done a how to guide. voila

[spencer_cammedvts]

its really easy to do and like its been said. it gets bloody hot with the manifold wrapped so fcuk knows what it would be like without the wrap! is supposed to give you a couple of extra ponies too! all in all with the reduced bay heat and the help in exhasut flow!

looks fcukin awsome too. look!

[Josh_Phipps]

Will i have to take the manfiold off or can i heat wrap it while its bolted on?? Btw liking the engine bay there Spencer :P

[spencer_cammedvts]

yeah you'll have to take it off mate. but its worth doing! there is heatwrap kits on ebay. thats what i used. you will also need some stainless steel cable yies to. get about 14-16 of the to be safe

[Josh_Phipps]

So ill need 14-16 cable ties. Is it jsut one layer of heat wrap on the manifold or do i go over it twice, how much wrapping will i need ?

[spencer_cammedvts]

well i bought 25ft of 2 inch wide and it did the job fine! just make sure when you wrap it, you overlap the warap by about an inch each time and keep it pulled real tight. start at the top of each tubular and wrap down towards where it joins into 1 do this for each tubular putting 2 ties at the cylendar head of each tubular ond one at the other end the secure the wrap on each tubular. should take 12 ties all in all but i say 14-16 so you got a few spare for if you mess up and have to snip a couple off!

[Josh_Phipps]

Thanks alot man, ill stick some pics up when im finished...

[bullit]

josh as i said before just scroll down to the threads at the bottom of the page and click on ax beefys thread. all will be explained chap
