Best part was sound the plug wires made when he removed them
I had to rewind it just to hear that Lmao
Giggity!
Looks like exhausting work!
It's a fairmount of work.
Looks like these jokes wrapped it up...
After all that work, I’d be running on fumes!
LEX Maximaguy87 wow.
I cant get my head wrapped around it
I love how in the beginning he's trying to teach us this counting the circumfrence to pre-trim the wrap, then by the time he's gotten to the other header he's "just use the whole roll, f*ck it!" lol
All of those college classes in underwater basket weaving finally pay off!
Eric, you wrap better than Kanye.
Low bar. Queezy barely bothers to rhyme half the time.
Thats an insult. Kanye is a gay fish. Eric, you wrap better than Lil Jon and the Eastside Boyz
TryDiy fuck Kanye its like saying Eric you wrap better than yo mama is not nice man :(
TryDiy hahaha that is funny
TryDiy that’s not hard to do considering he is the worst wrapper” on earth
Top tip: Ask wife for help! Small hands and an eye for neatness from doing crafts make the job easy and results better! DISCLAIMER: Your results may vary, I will not accept responsibility for injuries you receive as a result off asking! (mine weren't that bad)
So step 1 is to find a wife....
panzerveps step 2 is to get a project car so you have something to do until you are allowed back in the house!
wat if a female is working on the engine, wud she ask her husband? i wonder
Rule no. 1: no women around when doing what you love.
lol
mummification is a *dying* field
;D
I'll see myself out
😂Your level of humour is wasted here
I commented that then scrolled down to see this lol great minds, huh.
Excerebration was a growing field for a while - until someone invented the collapsible steering column, anyway. :-P
Best comment here.
Lmao!
That's a wrap!
Damn it. you took it! :-)
Kind of surprised that the car guy didn't use that slice of cheese.
exactly the first thing i was gonna say
Don't leave any small pieces in your pocket, that ends up in the laundry and ruins your wifes work things. Been there done that.
"thin on the inside fat on the outside" Just like my ex wife, im a pro already
I just used this exact stuff (DEI 1 inch) on my motorbike header, and you have just documented EVERYTHING I went through! Not cutting enough wrap, getting tangled, breaking the metal straps, wrap fraying...don't forget tiny shards of fiberglass EVERYWHERE....I basically sacrificed a mechanic's uniform thanks to this job...
They tell you to soak the fiberglass wrap in water to keep from shedding fiberglass shards. The titanium is made out of basalt, so it's not as much of a PITA.
Honestly man, great video. You didn't edit out the trials and tribulations, and your dry sense of humor made it hilarious. I think based on this I'm going to skip wraps for. Great content!!!
In your opinion,, what is the life expectancy of “wrapped” headers ?
a few days
It is generally 3-5 year
@@lukeschneider8760 you are right, my was 4 years
Handy hint: start with the longest pipe. If you come up short, you can use it on a shorter pipe and learn how much extra you need in the process. 👍
Not sure if someone mentioned this or not but to eliminate the fraying I use liquid super glue on the ends. Best way is to do a line of glue across the wrap beforehand then cut it after a minute for a very clean cut. Works amazing.
The music just dotted the i on this one. Well played, Eric. Well played.
For you turbo guys (and Eric may have noticed this as well), when you wrap exhaust and turbo manifolds, since it helps retain the heat, it can actually aid in spooling turbos faster since you're losing less heat. This could impact your tune, but not always.
Great video Eric!
i would've loved to see a thermal camera image of a before and after the wrap once installed on the car, as well as surrounding part temps
Guillermo Lovato they demish heat very well. I did this for my old truck. headers and a new heat shield inside and you can feel the difference.
what safety wire?
Engineering Explained meets ETCG
@paulsonrc If you could prevent wrap shifting it'd make more sense to have no overlap, exposure to laminar heat dissipation. Thanks for your presentation!
How many horsepower does this increase the performance to?
who thought that putting plug wires that close to headers was a good idea??!?!?!
FORD
CHEVY
JEEP
Everyone, unless its a hemi style or 4 valve. Burnt wires were always an issue with building motors.
Aircraft safety wire is better to lock down those wrap ends and any loose areas of the wrap. Those crappy bands break over time after a multiple heat cycles. If you use safety wire, be sure to get the special tool that allows you to twist and cut the wire. looks really sharp and very pro.
Yep - .032 SS wire and twister tool is the way to go!
Safety wire FTW!
Man, I haven't played with SWiPes since I quit working on aircraft. Kind of miss it.
Been watching videos to see how the old pros do it - so cool.
thanks for that info!
I literally did this the other day on my RX7 and saw this in my feed and was like "Waiting to learn I did something wrong" lol
Stainless Steel Hose Clamps Also work very well on wrap. I personally prefer the pre-soak wrap as it tightens up as it drys and doesn't tend to slip around with the heating and cooling cycles. Great video Eric, this will really help those who have never done wrap before.
I was thinking about using hose clamps.
Great video, always good to watch someone that is not a pro and shows their mistakes
..
I have found better performance and useful life of the headers by spraying them with VHT coating let it dry before installing the wrap, Then perform a second coat. Allow the second coat to tack, this will help retain the wrap to the header. If one is so inclined they can spray the exterior of the wrap too with the VHT.
Excellent suggestion. Thanks!
I have a 347 stroker with patriot mid lengths. I want to wrap them for under hood temp purposes. I heard a lot of people saying wrap ruins headers because they get too hot and rust. Does that vht trick keep that fro, happening?
In my honest opinion, nothing beats the awesome look of a wrapped pipe on a car or especially motorcycle. I plan on doing my header and bike now that I've seen this video!
P.S. Mummification is definitely a dying field. bu-dum- tiss!
Nice vid as always. More Bossa Nova music at ETCG :)
I wonder if screw type hose clamps might work to hold the wrap in place.
liked how at the end of the video, you shrank it, so the other video icons would not be in the way of your face. I hate that so much when it does that. So good job and good show.
Get a Jet Hot coating for the same purpose, and prevent corrosion/rust. A little more expensive, but has a limited lifetime warranty.
turbo looks good 🤘
When I wrapped my headers I did it with them off the motor , much easier that way. Plus I used some thin tie wire twisted together for tension (el cheapo solution) to hold the wrap tight as I went along. Then used the stainless clamps up near the exhaust ports on the head. I also kept the wrap away from the header bolts slightly so that I could still get the bolts back in once the headers went back in the car. Be ready for some smoke when you start it up the first time. Because the header gets hotter and it will burn off the paint that's on the header.
This is now an instructional video for Admiral Snackbar "It's a WRAP!" lunch place.
Hi: I loved this video!
Like millions: can we get a FLIR reading of heat exchange efficiency?
Like maybe a video detailing why you wrap and it’s pros and cons? Maybe use aircraft safety wire and demonstrate that tool?
Wrapping is kind of a dark art as the few people who know a lot about it are race car and aircraft/jet engine mechanics. It’s like welding; everyone want to know about it but no one explains it.
I am wondering if hose clamps would be preferable to the clamps they provided you with. They seem to be made of the same material, and hose clamps may work a lot better.
Were you supposed to soak the wrap in water beforehand or use water when applying wrap ?
Great video. Thanks for leaving the "mistakes" in, that's what we need to know!
Nice install. I always use worm-drive hose clamps instead. Also, I prefer PTP products over DEI. Just seem to be better put together IMO.
Why is there only 1 turbo on a twin bank engine v6/v8..
i mean yeah it will give boost but be not so efficient and also cause tuning issues as 4 cylinders driving a turbo and 4 are not. different scavenging and back pressures for each bank lol..
2 x smaller turbos running from each bank be better than 1 x large turbo running from only 1 bank.
or if it must 1 large turbo running from all 8 cylinders somehow
Look the left bank routes to the right side where the turbo is
kudos to you Eric,
great videos, I got some tips that'll save me time and material.
and i must say including your own mistakes for us to watch is incredibly commendable!
I believe it reflects your honesty and you are a better person for it.
you have my subscription,
keep it up Chief!
Is header Wrap better versus having the exhaust components ceramic-coated! what would be the thermal differences? Is there a big price point between the 2?
I really wish we could have gotten a temp measurement before the wraps and after to see how effective they are.
I'm changing my name to "Rusty Headers"
I have a 50' role of the same stuff sitting in wait in my room to wrap my Integra. haven't decided if I want to wrap the current header or get I new one. I'm super excited to cool the engine bay though
A tip for people making big power (with actual high exhaust temps) or have aftermarket turbo setups, would be to wet the wrap before hand and make sure to pull it EXTREMELY tight after each loop. Its the difference between it unraveling after a few heat cycles vs it never unraveling after 100s of heat cycles...
Header wrap is a good idea on any headers, doesn't have to be "big power" applications. I use it on my small power 545 stroker 460, the heat soaks into the starter and wreaks havoc on starting without a 30 minute cool down.
On behalf of everyone that likes to go fast, we need more Fairmont videos.
proper man!
That was cumbersome, but I'm glad u didn't give up.
Use hose clamp instead of these metal non-zipy-tie... so much simpler!
Just use stainless steel aircraft lockwire with a pair of twisting pliers or hoseclamps... WAAAAAYYYY easier.
Also some heatwrap works and conforms a lot easier when soaked in hot water ;)
Hello Eric, this is just suggestion; from front to rear, tube 1) wrap from header to collector ( the metal clamps (they will loosen up and corrode and fall off) suck don't use them, use safety wire, make a double loop around tube and pig tail tight. tube 2) wrap from collector to top and safety wire with double loop tight. tube 3) from collector to top and safety wire. tube 4) start at top and work down and include lower part of tube 3 finishing at collector and again use safety wire. The small band clamps will loosen up in time plus they fray the wrap material. When starting cut the material at 45 degrees and add super glue to edge so no fraying happens. If you use .032 size wire stainless wire ( as used in aviation) it will stay tight and no corrosion. good luck hunting for a job well done. I visit your u-tube often. Thanks
Moral of the story: if I ever do headers, I'm stopping by your shop. I'd lost it before I got one pipe done.
Hey Eric, great vid. I was wondering will the turbo manifold cause uneven wear on the engine? Would the turbo on one side cause extra back pressure on that bank of cylinders thus causing extra wear? Thanks
I mean the turbo is closer to one side, than it is to the other.
I think CV boot clamps would be easier to work with
Thanks mate. All the other videos seem to show Chevs. I'm about to tackle a Windsor so your video is quite relevant.
gday from Australia. Loving the Fairmont vids. It's what got me onto your pages. 👍
I did mine and after start the car like white smoke coming from wrap. Is that normal??
Thanks
Ive always used the "screw type"metal hose straps.
These days there are all sorts of coatings you could apply to your exhaust to keep the engine bay temps down. No need for a wrap anymore, unless you specifically want that.
Hi Eric
Mate use MIG wire to tie it up the rap all the tires can be hidden at the back of the pipes
How I did mine and it's been like that for over 2 years
Hey Eric. I got an idea for a video since you appear to be branching out on different topics these days. I heard that the reason many car jacks fail is because they run out of hydraulic fluid? Something like that. Perhaps you can do a video of proper hydraulic jack maintenance. My jack at times will start slowly coming down intermittently. Not sure why. I bought some hydraulic fluid once, but the jack appeared to be full still. Not sure what the issue is. It also creaks sometimes when it's lifting. Is that bad?
years ago I saw wrapped headers but would see Rusty headers not very long afterwards,well,I came up with a method to wrap headers so they NEVER RUST... I'd try to tell you right here but think too many wouldn't comprehend so I'll try to put out some sort of video...
Not sure what kind of turbocharger you got there, (sure you've told us) but I am a foreman at a facility that among other customers, manufactures components for Turbonetics.. The level of precision we manufacture them to, is just amazing.
Except that the turbo is Inhaling HOT ASS AIR if you’re running a turbo? Correct me if I’m wrong????
Correct me if I’m wrong?
You have some viewers that left "comedy comments". Some of them were pretty good. Thanks for the tutorial Eric.
I'm not a fan of headers. In my opinion, melting everything under the hood, burning plug wires, overheating the starter and taking up a ton of space is just not worth the extra horsepower.
You deserve your own spot on power block. Is that still on TV? Do people still watch TV?
Anyways. Nice job. Settled my debate on if I want to try to tackle this. Will be ordering some.
That look absolutely fantastic!
I found a trick you might try next time,
If you start at the flange and fold the first inch and a half underneath the header and begin rapping over the top of it you won't need clamps at the flange you will only need one final clamp at The Collector.
I did this on my land speed bike and never had an issue with it and the look is very clean because there's only one clamp showing at the collector.
have a good day
I just did this for my first time ever I had the fiberglass wrap, but then I sent it back and got the titanium wrap instead because everyone was saying that you didn’t get the little fiberglass shards in your skin when using the titanium wrap. I found out that is false. My arms are covered and little Stabbys I also saw a video where the guy said you didn’t have to wear gloves if you work with titanium wrap, also false. This has been a nightmare. It’s taking me all day to do probably about a foot and a half worth of header coming off my four wheeler. The absolute hardest part is getting it started and holding it in place so you can tighten the rest of it. After that, it goes a little smoother but me being me I thought I would have no problem with it. I was wrong.
I've heard that these wraps will cause damage to the headers. Water will get trapped in between the headers and the wrap and rust will be intensified. In a few years you'll need new headers. Think that's true? I just built a custom heat shield to put on my header. Because with my dual core radiator the ac fan is right on my header.
Dayum son those valve covers are ready for some SERIOUS blowby!
Professional Hot Rod Show...
We'll go to commercial and be right back. (Project done and perfect)
Erik...
F#$I it, I'll use the whole roll...
(Completes the wrap as it always happens)
Great and Realistic Video!
Quick question, I have an air intake for my suv, and it gets hot as hell under the hood, would those help if I wrapped the air intake tube with it, or would it be a waste of time/ money?
Much easier and better to use radiator hose clamps! Can't stand fighting those metal zip ties! Great vid!
If you want to cut to l wrap to length.
The math is Pi is roughly 3.142 multiplied by the radius squared, times the length of the pipe.
Trust me it’s not as painful as it looks.
So, if you’re wrapping a 2 inch OUTSIDE DIAMETER pipe you will divide that number in half and your radius will be 1”.
Write down 3.142 multiply by 1 inch radius = 3.142
Now multiply 3.142 by 3.142 you get or 9.872 inches. For each pass.
Now you measure the length of each pipe. Each pipe is 12 inches long.
So If you are using a 1 inch wide wrap, you have a 2 inch diameter by 12 inch long pipe, and you require a 1/4 inch overlap you will multiply the following.
3.412 x 3.412 = 9.872 in
9.872 x 12.25 = 120.93 in
10.07 ft add 10% for waste you have roughly 11 feet for each pipe
You will divide the total number by the width of the product for wider and multiply it for smaller product.
You see, it’s easy.
60$ per 100ft....jet coat spray $???
I dont know. This wrap is so popular doesnt look long lasting
...looks like a good temp bandaid
At best.....how many times will this need to be done with heat cycles and vibration....just thinking out loud......if they can come up with a spray can of this stuff......like spray. Truck bed liner meets, spray max 2k spray cans...some chemical guy would be a dollar richer....
Hi
What is the outside temperature of the exhaust with the wrap?
I ask because I am building an inboard marine engine and maybe I want to use not water cooled headers if temperature stays enough lowt
i just fired up my freshly rebuilt 87 dodge ram with a 318 and i wrapped my headers to but i used just normal stainless steel hose clamps oh and be prepared for lots of smoke from the wrap lol
Dont they make a ceramic paint you can spray on exhaust manifolds &headers the dissapate the HEAT
the first step in the instructions for the wrap I bought (Ledaut Brand) says, and I quote, "Protective eyewear and gloves recommended avoid inhalation (Of Loose Fibers)." 🤔🤣🤣🤣🤣 Umm, 😷 maybe? lol.
Wondering if your headers are stainless or not. I've read elsewhere that wraps can hold moisture and lead to premature failure of the header by promoting rust. The wrapping looks good.
Good thing u had those safety glasses, u might of accidentally wrapped yourself if u didn't haha
I hear the mummification field is drying up! Sorry not sorry!
"How to wrap headers" You don't.
Very informative. I have an SVT header I wanna wrap before I put it on my first gen ford focus and this gives me at least an idea how to do it when the wrap kit and gaskets come in. It's a really funky looking header and will probably be a pain to wrap, but the plus side is only have one to do since it's only a 4 banger. Lol
Reason why I love HPC ceramic coatings.....the wraps can look cool though. I have used a high temp epoxy in the past to keep the fraying pieces down.
It looks, oh so easy, BUT, what about if you want to wrap your headers with the engine bay in your way...Good luck with that!! And, what says all that stuff won't just unravel with vibration from, you know, THE ENGINE???
I’m betting regular old hose clamps would work fine.
Wrap the end in tape of some species to prevent that fraying.... Masking, electrical, duct.... whatever.
Just avoid the BS and use a regular hose clamp.... just put the screw where it's kinda out of sight, but still accessible.
dip or spray the frayed ends with some HI-TEMP paint to stop the fray from propagating! DEI even sells HI-TEMP siliconized paint you can use on the whole system.
I know this will make me look like a internet expert..BUT, I have wrapped the exhaust of every motorcycle I have owned (which is a lot). So, a few pointers... wrap towards to the collector, not away. wrap multiple headers together when they are closer than a 1/4 inch to one another. Loose wrap the amount of loops you need to make wrapping MUCH easier. I soak even Ti wrap to keep the dust/particles down.
I must say...I do not watch your Fairmount videos however I have always wondered what was those things people were using in their headers. Now I know what that is excellent video Eric A + Rating. About the Bell, I wasn't' notify at all, for some strange reason I wasn't.
The pop sound as you removed the spark plug tubes was so satisfying for some reason.
Interesting process to see, hey didn't you say you had like 30 Fairmomt videos backlogged? What about uploading more than once a week?
Imagine trying that when the engine is already in the car!!! Not being facetious though, but is it really worth all that effort? How many degrees lower will your underbonnet temperatures be compared to non-wrapped? Kept waiting for Boris Karl off to put in an appearance. Thanks for making the videos.
I saw a suggestion from someone to Superglue the ends after you cut them, rather than tape. . Glad I watched this before doing it though! Now I know what a PITA those metal ties are. I'm just doing a part of exhaust pipe so I'll probably just try hose clamps.
little off topic but are you going with those breathers on dark matter pikachu or are you goin with a caych can system? i would think for a turbo car that breathers would just get soaked in oil after going on a drive. with the blowby from a turbo, but i can always be wrong lol
They sell the smooth clamps at form groccier stores like fred meyers and I think I saw them at walmart too.
Gotta say Eric. That’s some shitty wrapping. But the looks don’t have anything to do with the performance. Good watch.
Its refeshing to watch a instructional vid that shows the actual challenges an average indiv. will encounter. The videos which makes it look like you can swap engines in an hour are irritating. THANKS ERIC.
