Why fluid absorption softens silicone from the inside, how oil mist and coolant reach the structural wall, why heat accelerates the change, what the reinforcement does while the wall weakens, and how to choose a lining for fluid contact.
How an elastomer ages on the shelf, the three factors that degrade stored hose, why silicone survives storage better than rubber, sensible storage practice, and how to judge an old hose before fitting it to a pressurised joint.
Why a clamped silicone joint is sealed by compression and elastic memory rather than force, what overtightening does to the wall and the reinforcement, how clamp band style spreads load, and how to inspect a joint that keeps weeping.
What makes up an intercooler water system: the pump and flow, the heat exchanger, the reservoir or ice box, bleeding, and what living with a water system involves.
Why the shortest charge pipe route is not automatically best: how volume, bore, bends and heat gain interact, and how to route charge pipes on a real car.
How to read an intercooler core specification: what the headline numbers mean, why core and overall sizes differ, and the questions a spec cannot answer on its own.
How intercooler placement changes performance: the airflow, heat exposure and routing trade-offs of front, top and side mounting, and how to choose for a given car.
A comparison of air-to-air and air-to-water intercooling: how each rejects charge heat, where each excels, what the packaging costs and how to choose for a duty cycle.
