power to weight - Toyota Yaris Forums

Yeah, any way you look at it, rotational weight is the place to do the reductions, unless cost is the main issue, then rock on with your bad self. I am not an engineer either, just like to research stuff like that. That's why lighter oils help improve power (even if it's just 1 to 3 hp), because the less resistance there is for the engine to work, the more it can put to the ground. That is why air intakes and headers and mufflers work so well. The engine works less to get air in and out, the more it can put towards the ground. Try sucking through a straw sometime, maybe 1/16" or so. Then try sucking through a straw that is 2/16" (or 1/8" for those who suck at math) and see how much easier it is. Same goes for your car. Slowly sucking is about the same, but suck something in really fast, and see how much difference there is. And it just occured to me how dirty this all sounds, but trust me, the idea is sound, and it has been proven by a LOT of companies.
