MrChow Posted February 15, 2015 Posted February 15, 2015 I know a few of you have painted your plenum (not a euphemism) , just want to get on idea of your process in the prep work, best paint to use and colours? I'm thinking a matt black to match the plastic cover, but i'm open to suggestions. ALSO, im toying with the idea of carbon wrapping the said plastic cover... thoughts please? Quote
SkylineV35 Posted February 15, 2015 Posted February 15, 2015 I Just found some satin black High Temperature resistant paint, Then removed my upper and lower plenum gave them a good clean, bath was absolutey minging afterwards lols, then dried and put two coats on. I believe the plenum is not as hot now as before. 1 Quote
Tricky-Ricky Posted February 15, 2015 Posted February 15, 2015 You shouldn't need VHT paint for plenum, its get hot but not that hot, just a degrease and a good clean should do it. 1 Quote
MrChow Posted February 15, 2015 Author Posted February 15, 2015 Thanks fellas. You shouldn't need VHT paint for plenum, its get hot but not that hot, just a degrease and a good clean should do it. What's VHT paint? Quote
ChrisB Posted February 15, 2015 Posted February 15, 2015 I cleaned mine with a wire wheel, used a couple of coats of Bilt Hamber Etchweld primer for the non-ferrous bonding layer, then a few coats of Hammerite hammered silver (other colours are available) direct to rust spray. It's been completely fine so far Quote

GMballistic Posted February 15, 2015 Posted February 15, 2015 Very easy mod to do MrChow, ...most have already described how to do it above. My thread from when I did mine just to give you an idea: http://www.350z-uk.com/topic/85949-thanks-lyndzzz-carling-plenum-painted/ Quote

My thread from when I did mine just to give you an idea: http://www.350z-uk.com/topic/85949-thanks-lyndzzz-carling-plenum-painted/ GM I read your thread the other day and saw what you done to your plenum and it gave me the inspiration to do mine 1 Quote
14N Posted February 15, 2015 Posted February 15, 2015 You shouldn't need VHT paint for plenum, its get hot but not that hot, just a degrease and a good clean should do it. Beat me to it. Doesn't need to be VHT. Mine's been Fosus ST orange for a while now, with no discolouration. Quote

Beat me to it. Doesn't need to be VHT. Mine's been Fosus ST orange for a while now, with no discolouration. I done mine to see if it would reduce temp inside plenum as before after longrun plenum was very hot to touch.. whereas now its much cooler. Dunno if it works or not just experimenting http://www.ebay.co.uk/itm/Thermacure-Satin-Black-High-Temperature-Spray-Paint-400ml-Stove-heat-Resistant-/261775726750?pt=LH_DefaultDomain_3&hash=item3cf30c989e Thats similiar to the stuff I used, I just thought theoretically if your plenum is cooler then the air going in would be cooler.

Tricky-Ricky Posted February 21, 2015 Posted February 21, 2015 (edited) Placebo effect! you wont reduce the plenum temp but using any paint finish, even an isolating gasket wont make much difference, because the plenum sits above the V of the engine so receives a lot of radiated heat. In any case the heat wont make a big difference as once the engine is running at anything over idle then the boundary layer effect takes over and heat is not transmitted from the almost static layer of air next to the plenum wall to the moving air .

Mikey Thompson Posted February 22, 2015 Posted February 22, 2015 (edited) Would it make more sense to have it chrome? I always though black was the most absorbent of colours (referring to the heat soak) Edited February 22, 2015 by Mikey Thompson Quote

RobPhoboS Posted February 23, 2015 Posted February 23, 2015 I bought this as I want exactly what it does, black wrinkle matte finish, and bonus of no primer it says (have some upol acid etch on standby just in case). http://www.ebay.co.uk/itm/VHT-Black-Wrinkle-Finish-Paint-Aerosol-310ml-Crackle-Spray-crinkle-effect-/141535788596?pt=LH_DefaultDomain_3&hash=item20f430be34 Quote
