Subject: Re: average operating temp. by bogus on 2012/5/8 16:29:13 Add in high-capacity dual core aluminum radiators and fans set at super low temps, the 160F stat became a dangerous thing. The preconceived notion was that cooler engine = cooler intake = more power production. The problem with that theory? Cooler engines are more prone to violent wear. Also, the only part that really benefits from being cooler is the intake, so if you really want cooler, either ice it down between passes or get one made of composites that don't heat soak in the first place. What matters then is: a cooler induction charge. Being sure that the air drawn in is cooler and not coming from the engine compartment. This air is denser and packs more oxygen per cubic foot than does hot air. This is exactly what an intercooler does for turbo engines. It cools and makes even denser the incoming air charge. This is necessary because the turbo, by using hot exhaust gases, in junction with the physics of compressing air, the intercooler becomes an absolute necessity! Same thing applies to the supercharged engines. |
