So what Im wondering/thinking about is power... I know in an internal combustion engine more power generally equals more air and subsiquently fuel. But... What about effiencey? Like letting the engine breath better? By means of less restrictive intake and exhaust? (Warm air intakes included) Or things a little more in depth like a very mild cam shaft? (Think like an RV cam) And things like E-Fans or A/C deletion or heck even an electric water pump. If you can make an engine work less to bring in air and exhaust air wont thag equate to more engine effiencey and inturn fuel effiencey? Im really contemplating a full exhaust system for my truck. (headers back) Are my thoughts off base or may be just need fine tuning??? Thanks this forum has be awesome so far.
