The RPM where you feel your car pulling is where the power band is. Look at horsepower and torque curves (dyno graphs) on google and you will see exactly what a power band looks like. You will want to launch your car with your engine revved such that after the clutch grabs the needle drops to around the RPM where the torque curve for your car shows it is a constant level (not where it is rising steeply) so you get a strong pull at takeoff. Does that make sense?
High revving lower displacement engines such as VTECs have the peaky power (in the top end of the RPM range) but larger displacement N/A engines can have more torque in the low end too (i.e. Nissan 350z/370z).
