Good kill and all, but 20 car lengths sounds a little much.. maybe you simply misjudged how far ahead of him you really were..

 

quite possible as i was looking in the rear view mirror,

my power basically fades at 7500-8000rpm's, but i let it go higher as i want to shift and have power right away,

it doesnt hit a brick wall at 8k i just know it isnt pulling as hard as at 7k
