Turbo Beanies/blankets

[el capitan]

I have a turbo bag on mine, been on for around a year now with no negative side effects as of yet.

I've been contemplating with the idea of a beanie but have also heard mixed opinions on them "for" & "against"

Running a high mount set up the beanie is a nice easy way of helping engine temps and also budget compared to getting my manifold sent away and coated. Im going to wrap my dump pipe and obviously make up a new heat shield but still wondering if its worth running a beanie or not and also interested to hear others opinions???

Cheers Ben

I ended up buying a beanie from hp in a box.....and I've gotta say I'm impressed with the quality and fitment of the product. Most of the beanies I see look like a bloody silver nappy wrapped around the housing but the hp in a box item was a much nicer item.

Had it on when the car was being dyno and it certainly helped temps.

I'll post up a picture when I get the chance.

Cheers

Here is a pick of my setup, also dump and front pipe heat wrapped.

My turbo s2k was on the dyno yesterday to bed in the rings and I had a chance to measure the heat in the exhaust side with an IR heat gun. It was on the dyno for hours so this really simulated hot track condition.

I used to have a beanie on the Turbo but did not think I need it since all of my exhaust side was ceramic heat coated. The pipe to my wastegate was not coated and is heat wrapped though.

Anyway the result was amazing. The wrap is more effective than the heat coating. It was roughly 40 C lower. Could have been the good Tomei wrap I used. The whole manifold was glowing red hot during most of the initial run. It reached 500C at some stage during the tune. No wonder why the mainifold wrap never last as long as people like.

If I have to do it again I would heat wrap rather than coat. Many coating places don't recommend coating + wrap because the wrap traps the heat and the heat wears off the paint. I am putting my turbo beanie back on, will fabricate some more heat shield and may be add an air duct to the exhaust manifold.

Has anyone had cracks in the exhaust manifold from heat wrap?

The place was called Competition and Industrial Coatings in Perth. Cant remember cost off the top of my head. They do the inside and outside of the manifold (and ex housing) in a double layer coat of the black extreme coating.

Here's an example of their work:

Man that engine bay is awesome-nice work mate.

Big thanks to all the guys who posted in here-helped me out heaps

Has anyone had cracks in the exhaust manifold from heat wrap?

Common with Stainless pipes I do believe-shouldnt be too much of an issue with Mild steel systems due to Mild steel having less expansion than Stainles-once again maybe wrong here too but its what I heard my exhaust guys say

That engine bay is unbelievable.

I am a big ceramic coating fan, I prefer it over heat wrap etc.

i had a jap brand stainless manifold cracking without heat wrap, it cracked at the weld on the collector

i think stainless manifold is just prone to cracking because of its mass and how it has to support the weight of turbo, dump etc..

spoke to a rep at GCG, they said cracking stainless manifolds are quite common, regardless of whether its Chinese/ Japanese/ local/wrapped/ not wrapped
