Exhaust Wrap

[rescue dude 0]

As above, thinking of trying it on my road/hillclimb/sprint car to see if it will reduce under bonnet temps and improve engine output.

 

I have a four branch Magnex manifold and to be honest it doesn't look like it'll be that easy to fit anyway.

 

Is there a correct way to fit it and does anyone have any fitting tips if I go ahead with it.

I've heard stories of people applying it wet, this keeps the itchyness down, but it also then shrinks slightly as it dries out, meaning you end up with a tighter fit. Not tried this myself though.

 

To secure it you can either use lockwire, or some of the stainless steel cable ties available on your favourite online auction site.

Thats the correct method of applying it.

I used to wrap about 6 a week for customers and found the best method for holding the wet heatwrap in place was to use lockwire, though you need to purchase the right tool (about £50 off the top of my head). I found metal cable ties do not tighten as well and are more of a paint to cut down so they are neat and tidy

As it dries it shrinks and stays neatly in place. I always let them dry for at least 12 hours before fitting them.

I wrote a guide for work once which might help here

Never had a problem with itching, though gloves are a pain so I used to have stained hands from the coated heatwrap lol

Blimey that looks a bit of a ball ache.

 

May see if theres someone near me that'll do it or study the job a bit more.

 

How much wrap you reckon i'd need for a four branch Magnex?

Can it be done mainly from the top or is it easier done with the car in the air?

 

I'm looking at the second method in your guide Batfink.

[Batfink 201]

I've never done one on a car, but that certainly makes the task harder. If you can measure the lengths you need then you would start from the top to do the primaries, then move under the car to do the secondaries.

One roll of 2x50" would do a Pug 106 manifold so you would have a little spare for a 205 one.

Thats what I was thinking.

 

If I do it i'll remove it to make it easier that way I can do it in comfort.

there is a post on here somewhere saying this is a bad idea and a link to why but i cant find it.

Go search on Guy Croft's website, where Mandic (Ziga) from this forum asked about whether exhaust wrap is any good or worth bothering with.

 

Excellent article. The extremely technical conclusion is "don't do it".

Interesting piece that.

 

May have to have a rethink.

 

Increasing ventilation is the plan then.
