Engine Bay Heat Management

Excess heat is the enemy of performance and controlling heat inside the engine bay will net some minor to noticeable improvement in performance. The amount of improvement will depend on how bad the the heat soak was in the engine bay to begin with and by minimising it to lower the Intake Air Temperature and Fuel Rail temperatures.

This is about my experimentation with wrapping the airbox and fuel rail with heat reflecting materials to minimise heat soak, i'll continue with this article in two sections - 1) Air box heat insulation and 2) Fuel rail heat insulation. Speaking about fuel rail this is a non-return type fuel rail and the fuel that comes upto the engine bay stays there till its injected. For wrapping I used DEI ReflectAGold after reading about a lot of available options and checking availability.

Wrapping the exhaust is the most effective way to control heat in the engine bay and also it keeps the exhaust gases hot and the gas velocity high, but that is for another day.
