400ex High Rev CDI box

Can anyone tell me how much faster one of those White Bros. High Rev CDI boxes will make a 400ex go in a strait drag race? Also, how much faster would a 1 tooth larger front sprocket make it go? i know it would make me jump off the line slower, but how much will it add towrds the top? Thanks

these rev boxs wont help much if your machine is almost stock, as soon as you fool with engine/gearing you will see some noticable changes
