Exhaust wrapping dump pipe

[Newbie GT]

I created this thread so it won't flood Manaz (Roberts) topic

What is recommended in a DIY tape heat install and suitable product?

And yes what are the benefits does it really make a difference to heat produced. I was under the impression that wrapping would keep heat in pipes making it hotter ?

Thanks

It does, and that's the desired effect. In theory a hotter pipe means gas will flow faster inside the pipe.

What sort of dump pipe do you have? Apparently a ceramic coated dump pipe doesn't require wrapping. I've also heard that wrapping slows down the heating and cooling cycle so it can prevent stainless steel from cracking.

Good thread.

Im getting the same dump as Robert has and I also share the same concerns he has due to the cat being so close to the trans.

I am thinking of either wrapping the dump or wrapping the trans with this stuff to reduce the heat. http://www.zircotec.com.au/zircoflex.htm

Im thinking of running the self adhesive type though and probably only 1 layer.

Wrapping the trans ……… Not the smartest thing to do unless you like changes out boxes.

Most wraps will require reapplication and ongoing inspection, really not worth it unless generate some serious heat. Ceramic coating will work a treat on most materials and requires no reapplication unless the mechanically removed.

I didnt know that. (re: wrapping trans) Perhaps I'll steer clear of that technique then.

I guess what Im looking at is the most cost effective way to protect the trans from the ongoing heat it will be receiving from the cat in the dump as I have read the dump will be mm away from the trans casing. Perhaps the only way is ceramic coat spraying it?

Your trans is casted aluminium with a serious of webs that have been casted into the housing to provide strength and manage heat dissipation.

Are you running a larger turbo or headers??

How close is the cat to the trans??

Stock turbo and headers.

Ive seen pics of the this dump fitted and its probably about 5-10mm of space between cat and trans casing.

See pics in this thread viewtopic.php?f=55&t=25306

Ceramic coat it, wrap it (50"x2" DEI Ti wrap would be nice) ties and or hose clamps, then ACL shield over the top to protect the wrap.

Or one or more of each pending how much overkill you like.

Wrapping ceramic coated exhaust components is a fire hazard

Just saying

I sent an enquiry to Zircotec regarding their ceramic spray coating and pricing. Waiting to hear back from them.

But considering Im running stock turbo, stock headers, and not tracking the car, it's gotta make me wonder if Im being overly cautious.

I've seen references to ~1mm of separation between catalytic converter and auto box. That's tight...

It never hurts to be aware of what the options are, and what the costs/benefits of them all are.

Then you can perform a cost/benefit analysis, and make an educated decision.

Leaving everything stock may be your end decision - but you'll make that knowing what the options were, and the pros and cons of the alternatives.

Yeah thats true Robert. The age old saying of its better to be safe than sorry springs to mind. I'd be keen to see what price the ceramic spray coating is from Zircotec. Ultimately its the best option but it's also the most expensive.

As I read their website, they don't do the spray product here yet, that's only done in the UK at this stage. I've asked them if their adhesive sheet is uni-directional or bi-directional.

I also just spoke to High Octane Performance Coating again.

They've quoted me $150 ex GST to coat the downpipe in a 1000C ceramic (black) or $180 ex GST in a 1400C ceramic (titanium). I also got quoted $90 ex GST or $115 ex GST (black of titanium respectively) to do the hot-side of the turbo (though I'll have to disassemble/reassemble the turbo myself for this). They quote a 7-day turnaround on jobs.

Thanks for that, Thats a good indication on prices.

Not to sound like a tight ass, but whats stopping you painting it yourself with a heat resistant coating?
