Header wrap - wet or dry?

[jonbullnose]

i normally do it like this waring a pair of gloves leather is best latex just rips ,put the ties on like a cable tie if your type are the ball bearing type? where the ball bearing is put your thumb on top of it get a pair of electritions pliers ie thick nose ones pull the pointy end tight with the pliers still keeping your thumb on the part where the ball bearing is press down with your thumb while pulling with the pliers tight then still keeping the presssure on with the pliers and thumb bring the pliers over the top of your thumb with the pointy end so the pointy end gets pulled tight over the top of the ball bearing and sort of double back on its self this holds the ties where they need to be with out doing this you will never get the ties tight enough and they come loose with the vibration otherwise, you can cut the extra off but only do this when you have finished the complete header as they are very very very sharp once cut and you will be cut to ribbons good luck you will get some that do not work sometimes

Thanks for the advice - I think mine are the ones which don't work well as I've tried your method tonight and they just will not tighten up. Going for the jubilee clips and stainless wire for the larger parts!!!

you can buy similar but better ties intended for cv boots

[jonbullnose]

yeah it does take a bit of practice to get them tight and every now and then you will get one that does not work you do need to have enough wrap on to be able to compress it a little when you tighten them and you do need to pull them very hard as you need to stretch them a bit, as when you let them go the ball does take a few mill to lock up once you get the hang of them it only takes a few second to do it, if you cannot get on with them i would just use stainless steel mig wellding wire as jubilee clips look pretty horrible when they are on

Thanks guys - I used 15 meters

[SUPERCHARGEDGTA]

looking good dude

[bhm1712]

good job you did not buy the 5mtr roll then

Haha yes!

I bought 40 meters so will probably end up with one spare roll to do the starter and finish off the collectors once the system is all coupled up to it.

well done looks good nice and tidy it would of looked cr+p with clips
i would add another tie if you can just where you have finished the over rap of the 4 pipes just before the bends as when you start handling the header or trying to get it to fit in the tight space that section can come loose you often need to join 2 ties together to make it reach

i will do that!


The only bit im not 100% happy with is the 2 central primaries at the top - because they had to be wrapped together and due to the strange angles of the tubes the wrap is tight against the tube but baggy as it bridges the gap between the 2. I tried all ways to get round this, but with the 1/4 inch overlap required i could not prevent it completely. The only way it went tight all over was if i let the wrap fall naturally where it wanted to go, but there were gaps then. Having said that its not going anywhere...its on there solid

Otherwise im happy

[jonbullnose]

yes is always loose there, when it gets hot for the first few times it goes tighter

have you got enough clips? I've got some spares if you need some

Thanks John - I got 30 with my wrap and I used about 12 on this header as I wasted a few trying to get them right. I think I should have enough for the other one.

There are actually 10 clips on the header but I aimed to hide most of the anchor points and only have the tops and collector ones visible. The rest are hidden by the wraps on adjacent tubes!


I'll give you a shout if I do need some!

dose look neat

Not bad for a first attempt me thinks!

It's worth taking the time and effort as I want these to last me a while! And I want to enjoy cooler driving in summer. The people who sold me the wrap recommends sealing the wrap with high temp silicone paint - what are your thoughts on that?

[SUPERCHARGEDGTA]

not heard that before
they smoke like a bush-fire as it is on first start up, without burning paint as well

[bhm1712]

Apparently it's basically VHT branded paint so you can choose any colour. It helps to prevent fraying at the edges and stops oil and water penetration and lengthens the wrap lifespan.

This is what they told me to use

yeah never heard of painting the wrap before i would think it would just flake off but i could be wrong
does not last that long on the steel of headers starts to flake off after a while i thi9nk you should photo the next header as you go on a step by step thing and we could add it to the tech section as a how to

complete with ruined hands
