The engine incorporates many more lightweight features than the LSA did. A smaller supercharger, aluminum balancer/damper, forged pistons/rods/crank, titanium valves. All of these things add up to decrease reciprocating mass, and increases how quickly the engine spins up. Many of you already know this.
That all said, I thought the LT4 spun up pretty damn quick. I was in the manual transmission car. If you watch videos of the automatic, the engine spins up and responds instantly to the different gear changes with little to no jolting of the passengers. |
Not really , at some point the airdinamic design will be more so than the weight and gearing
