Heat wrapping pros - cons?

[LoganK]

Picking up my 98 spec manifold next week at somepoint and was thinking about heat wrapping it before I fit it to the car.

Just wanted to know is there any real benefits doing it?
Would you advise doing it?

Thanks

I heatwrapped my d series mani and it made the bay cooler but it made the exhaust louder.

ive done mine, i dare say it does lower engine bay temps at very least but mainly looks good to me ha

cant be any downsides as far as i see

the manifold gets hotter transmitting more heat to the cylinder head and internals. You dont really want this...

Also lets the exhaust gases travel faster so you get better flow but on a standard engine I doubt you see the benefits

exhaust is louder?

Thanks mate, I think I will do it.

Yeah it does look good haha did you wrap it yourself? I have heard some stories about wrapping it, some say its best wetting the wrap, also not to do it too tight or over wrap as it can sometimes damage the manifold?

(P.S your car looked amazing last night haha defo want a set of canards, look so aggressive !!)

yeah I know that doesnt sound too good, I am unsure on what to do, I want to because tbh I like the look of it haha

Yeah, will make the exhaust a tad louder. Kept the engine bay cooler and reduced water temps too.

I dont see how wrapping it too tight will damage the manifold - However may cause the wrap to damage itself and weaken (eventually breaking).

I also heard of wetting the wrap, I didnt however. Be sure to use plenty of stainless ty-wraps though!

Have fun

Thanks! I am thinking I may as well do this.

As for the stainless wraps, where should I wrap it? I have seen then ty-wraped up at the top but should there be any going down the manifold?

I am sure I will have fun just need to remember to wear gloves as when my mate done his he didnt and he had itchy hands for days

Ill try dig out a picture, I did find though - towards the 90degree bend around the sump (most exposed to the airflow) the wrap kept breaking/getting loose. In the end I made a X pattern for it which solved it.

Yeah and use some clothes you dont mind chucking, I used some thermo-tec 'cool it' and the copper dust went everywhere - right fudging pain, I'd get a mask too as the dust becomes airbourne easy.

Hope these help.

yeah done it mayself mate, tbh i did wet mine but it was the first time i had done it so no idea whether or not it makes a difference, DEFFO go for a decent wrap instead of the ebay stuff though, so much easier to work with a will last longer/look better in the end

* thanks alot mate so did yours, looked very clean love my canards haha

Cheers bud! This should help I will put a few pictures up when I have done mine over the next few weeks!

I think I will try the wet wrap idea and also what wrap would you recommend as I have only been looking on ebay haha

Thanks, Iv not long got it cant wait to make it more my own !

Thermo-tec 'cool it', DEI wrap, think thats been bought up before.

 

[Topher-EK9]

i've heard of people wrapping mild steel exhausts and of course once the wrapping got wet it stayed wet and rotted the exhaust..

 

[dhdavectr]

Don't buy the cheap eBay stuff, it falls apart after a while

 

[jesse888]

I've used dei titanium befor. Good stuff, could rest my hand on my turbo manifold even after a good run.

I will have a look into both of there

I think I may just lightly spray it with water not drown it but I will watch a few videos before doing this.

Yeah I will get a decent brand

Sounds like the DEI stuff is a good shout !


Also does anyone know how much I will need of this ?

 

[jesse888]

The dei titanium you can put on dry, I did and it was fine

Thanks, less worry about it drying then.

Looked on ebay for the DEI stuff and can get 15ft of 2" wrap from £23 think that should be enough for the full manifold ?

 

[jesse888]

I doubt it mate, I've never wrapped an n/a mani befor. And they go all the way under the sump so its a long way.
Best for someone else to answer that really.
