The cast aluminium on the Alloytec engine intake manifold / plenum chamber is really rough and makes it near impossible to just polish.
Some companies offer Ceramic coatings, or similar to give it that bling factor, but also promote the dissipation of heat.
I'd like to know, if ceramic coating is used on parts such as headers and turbo manifolds to keep the heat in, wouldn't it be a bad thing for the intake? Would it create issues such as heat soak and increase the temp of the intake air?
Your thoughts are always, greatly appreciated, thank you.

The ceramic coat will look crap unless you polish the alloy first anyway - done it heaps of times.

Yeah just use a lower grit sand paper and start sanding away you will get there eventually, the alloytec manifold doesn't look too difficult. You can't beat a polished finish IMO.

Thanks M@, so you didn't get any so called heat soak then? It didn't affect the performance of your car?The ceramic coat will look crap unless you polish the alloy first anyway - done it heaps of times.

I got some pics here courtesy of Ben Hoskings at www.streetcommodores.com.au, as I frequent this site to get the latest on what people are doing to their Alloytecs. The pics are from his project car XXX
Some pics of them trying to polish the inlet manifold,
And finally the finished product with the Ceramic Coating, or what ever coating it was that they used.
This is certainly what I'd like to do, but being the daily driver my car is going to be, if its going to affect the fuel economy then its not really worth it.
But as they say, " Bling Factor will always out weigh practicality "

My mates 300ZX TT has the whole intake HPC coated in the ceramic hypercoat.
I didn't measure manifold temp before and after as I only just got my IR thermometer back recently after it went walking 5 years ago. It certainly doesn't have any heat issues and he is pushing a fair bit of boost.
When I said I had done it heaps of times I meant ceamic coating parts with and without polishing them - I was always sorry when I didn't bother polishing them first and usually polished them and had them redone. The ceramic is very thin and will really only cover 400 grit sandpaper marks at best so not too much point going much beyond 400 or 600 grit.
