thanks bro...it really help...i will thermal thermal wrap 1st..then put some scoop or hole on da hood...or juz replace with ne carbon fibre hood...Dear admehdivkia;4093232]
Here are some idea of how air flow under the hood!(no so accurate) As u can see most of the flow facing toward the firewall(where the chassis no: is!) and down flow under the engine.
So! some idea to reduce heat under the hood:
-(white toyota)lifting the hood! Two screw each side, just add some washer but not to much were it will disturb engine cooling and aero of your ride!5mm-10mm. Not everyone like this idea were it make your car look like unfinished work of claim shop!
-(grey car)Hole on your hood! Where u must understand that the highest temp under the hood is when u queuing to go in and out KL or idling the engine at full stop! So remember that hot air always goes up on stand still! Correct?:rolleyes: Bad news is rain will pour in and JPJ can give u a ticket if they want to! accept factory cars! can ask body kit shop:rolleyes:
-(painted ex)ceramic coating reduce heat but not a lot, expensive but looks sexy Your choice!
-(ex manifold)Some idea where to wrap!(green) as a simple explanation, just imagine ex-manifold is very hot when engine is running! so if u wrap the hot surface to a smaller surface what will happen?:rolleyes: then smaller area that generate heat, so it get cooler! But u still can touch it Dont worry the heat wont build up on idle, were the output heat is fixed!
-(ex manifold)Some idea where not to wrap, hot spot and the crack point(red) usually ex manifold crack is cause by -sudden dramatic temp change. example straight to engine wash after a long ride!
-unsupported exhaust system, mean to much stress and weight rely on ex manifold!especially week stainless steel type manifold.(golden brown, used!)
-quality of weld and thickness of material(to thin and thick also cannot)
so....so...so few choice and idea to share but is for engine bay!
Hope this help! :wavey::wavey::wavey::wavey:
there r so many brand of thermal wrap...in ur opinion n experience...which thermal wrap is da best...i heard non asbestos is da best..is it..????
