2019 summer race.... Jadaharabi vs 318willrun

Lol. Thats funny cause when I was building it. I thought this engine was gonna be badass and radical. Now i'm like.. nah this is nothing I drive it all over the place, doesn't over heat. It's loud and shakes, but damn it thats the point. lol

Am I imagining things. In both videos it seems like when your car shifts about mid-track, the sound of the engine changes and it looks like the car slows down it's rate of acceleration.
