I wuldnt trust the cheap sh*t off trade me, I bought a bit of it, and it caught fire on my extractors :( The dytech stuff made a huge difference, did my extractors and half way down my piping, then just the section over my diff.


I fix it down with lock wire, its like there is nothing there cos the wire is so thin :D

pardon my ignorance, but...

what does it do other than keep the heat in the pipes?

is it to do with keeping it hot to keep the exhaust gas speeds up or am I completly confused?

Does it also quiet it down a bit?

While asking questions, adding additional pressure to radiator, other than upping the boil temp, what does it do, and how does upping the boiling temp help anything?

dont think wrapping ur headers will change the boiling temp....dont see how it will change any temps at all, it will prob keep the engine bay cooler and help with water temps.

Hmmm... On my ae85 I wrapped the factory manifold on my 4AGE down to a flange where the original cat would've been. I tried to keep the overlap to around 1/2, and I think it took a bit less than 15m. My friend got it for me from a marine store for reasonably cheap, i think he said it was around $50 for the amount I used.

From my understanding the main reasons for heat wrap is to keep the heat in the exhaust for two reasons. One to keep the exhaust speed up, but more importantly (on the manifold/extractors) is to keep the heat out of the engine bay. Supposed to put less heat strain on everything else in the bay help it all to last longer, and work more efficiently for longer.

As a side bit, it does help a bit with exhaust noise. But really most effective at that if you wrap the whole exhaust.

Increasing boiling temp is just a way to try and stop engine overheating. Assuming the boiling temp isn't above the engines proper operating temperature the increase allows the radiator fluid to absorb more heat before it boils. When it boils radiator fluid absorbs a lot of heat, but after that it becomes practically useless...

Thanks for that, I figured it was something along those lines.

again, thanks, I'm learning fast, but some of the little things just confuse me

I would dare you to wipe your arse with fibreglass!! Especially the Pink Batts type, but I don't think anyone would notice that you did as you just be scratching your arse all the time as you usually do. :P

No you've all got it wrong. Wayne is actually a big pussy trying to be kool by having 100s of parts and tools lying around his garage so it looks like he's busy doing something when he's actually not.

That 1UZ has not moved an inch from where I saw it last before Xmas Wayne!!! :P

And it's not the I Don't Care Burger...It's A Care Burger, Why? ...Cuz it Cares Damnit!!!

I used heat wrap, long story short to stop my car catching fire more than twice.

Funny enough I had to do that exact same thing in Fiji when I cut myself open on the reef while surfing at Cloudbreak. They had no first-aid stuff on the stupid boat!!! But they had superglue, and I used that, waited for it to dry then went surfing again. :D

Im hard. :twisted:

Slashed a tendon in my hand with a machette and didn't notice till I couldn't grip the doorhandle to get into the house... Oh bugger

Shattered a major bone in my wrist, still finished my workout, did my shopping, went to see my mum, cooked my tea and did my house work and only drove myself to hospital when woke up at 3am screaming in pain.

MY WIFE broke her back and walked around for a week before she went to hospital about it and only then because her legs stopped working..

THEN the other day I was struck by a meteorite and instantly vaporised I stappled myself back together and still worked 12hrs the next day, If you told the young people of today a story like that they wouldn't believe you.

NOTE: Only one of the previous stories is made up but which one?the rest we put down to stupidity

p.s the supaglue thing is old hat sparkies use it cos it works better than insulation tape and stops you getting blood all over peoples houses. They use simiar stuff to close you up after operations.
