i'm gonna try shifting really quickly from 1st to 3rd, and not letting my rpm needle gets past 4500 in the process. i'm also gonna try focusing more on my guages instead of looking at the other car or feeling out my car. that should gimmie the discipline i need to get to speed quicker.
You have to spend countless hours working with the clutch and rpms. Try leaving watching the rpms by slight pressing the pedal down. Try reading your pedal depth, 1/8th throttle, 1/4 1/3 etc etc.
So... tomorrow spend the day leaving the light with nothing more than 2k rpms. Try all different throttle positions. Then work yourself up to 3K seeing what pedal depth will work best. Of course night time will be different than day time so you must memorize these needs for the best way to harness your power.
If it makes you jealous....i launch at 4-4.5K
