Heat Management, Part 7

Hi guys, this is another chapter of heat management. I've been observing around workshops and some race cars on how they have been managing their heat. Please scroll down to view some juicy pictures and explanations of how heat is managed on these cars :

 This picture on your right is a Honda Prelude with a H22A Vtec Engine, bolt-on-turbo. Pay attention to how the turbine housing is covered with a turbo blanket and the hoses wrapped with heat shroud/sheath so that the heat of the turbo doesn't melt the hose down.

Mind you, the steel braided hoses for the turbo oil feed is also heat-resistant.

 This picture on your left, shows that the downpipe after the turbo being wrapped with DEI Titanium Exhaust Wrap for that sexy looking finish and insulation. Again, note the silverish looking pipe beside the downpipe. Tidy much.

 This picture is taken at Autobacs anniversary in Meru, Klang. I didn't have a good look at the car but the top is wrapped with DEI Reflect-A-Gold heat reflective tape. It's probably an airbox for the air intake system.

This picture is taken from a Satria Mivec, wrapped intake manifold also with DEI Reflect-A-Gold heat reflective tape. The owner wants to reduce his Intake Air Temperature(IAT) to reduce knocking/pre ignition. This car goes for Saturday Night Fever races in Sepang from time to time.













A friend of mine drove his Waja up Ulu Yam and it caught fire. The cause? The heat of the exhaust maifold(as he has a top-mounted turbo) melted the top air-con gas hose. Compressor oil was all over the engine and ignited the moment it touched the exhaust manifold. Thank God for fire extinguishers and an extra help from friends and cops from the nearby police station. A bloke even did a Tripe-H entrance by drinking F&N orange and spew it onto the engine bay while it was on fite.

 The engine bay caught fire the moment he switched his air conditioning on. Gas pressure built up in the hose and it ruptured almost immediately.

 The ruptured hose, it was only like a couple of inches away from the turbo.

 In the process of putting out the flame.

 The car owner inspecting, thinking what's gone wrong. Initially they thought it was coolant as it was greenish around the engine bay. Found out that the next day it was the compressor oil igniting.

 Flame out - the end.
