Crusti, aluminum connecting rods exist, and so do lightweight flywheels and lightweight driveshafts. If those parts didnt work, they wouldnt keep making them for years and years. People would eventually figure it out and stop buying that product.
YOU didnt notice the increase in fuel economy and acceleration because YOU did not have the right logging tools or engine setup. I, with my little data-logger software and my lead foot on the dyno DID notice a difference in fuel economy and acceleration when adding a knife edged crankshaft to an SR20DET for instance.
Just depends on the setup and intended use for the vehicle. Lighter is better in general because rotating mass is an energy hog. Thats all Im saying and its dead accurate.

Seriously...
This is the last time i waste my life answering you.
so...
1/ business 101: sell what people want, not what people need. People keep buying chassis braces made of chinese cheesy metal. Or pills that make you lose weight. These things NEVER WORKED in the first place. And they keep selling. Your argument is invalid.
2/ i never said getting lighter parts had no impacts, i said most people dont need them and cant tell the difference nor get some benefits out of it. Yes, that includes at least 90% of zilvias members. Including me. You ... well you are just a lying fool so i dont know if i should count you as a driver.
3/ fuel consumption. You have great logging tools. I have a simple calculator that can do "fuel added at the pump / mileage done since last refill" . Guess what ? THAT is what fuel consumption is about. 5000 miles later, my fuel consumption is still the same as before. So i really dont care what your fucking damaged brain tells your fingers to type. MY FUEL CONSUMPTION HAS NOT CHANGED, AND I DONT NEED A FUCKING DATALOGGER TO COMPUTE THIS.
4/ Rotating masses act like a capacitor. They dont hog energy, they store some, then give it back later. What matters is how much energy. The answer is nearly none.
You like calculators ? Try this one.
Flywheel Energy Storage Calculator - Kinetic Energy, Inertia, Centrifugal Force, Surface Speed
At 100km/h, an S13 standard diameter wheel + tyre has a diameter of 618mm and turns at 860rpm.
In the worst possible scenario, if it weights 32lbs, and all the weight would be on the outer diameter, the whole wheel at 100km/h has 12 joules stored in. If the weight is even (disc form), that goes down to 6 joules.
Cant you see how this is ridiculous low ? Yes, going for half weight reduces it to half of this value. But guess what ? THAT IS STILL NEGLIGIBLE.
FFS providing 6 joules with a 300HP engine takes 27 DAMN MICROSECONDS.
5/ go fuck yourself and get some brain surgery, twat
