Economic engine?

soo i've been playing this game for a while and iam enjoing it too much 
so i'am wondering what you guys think about this car/ engine when it comes to economy and power, speaking of power is 120 ponies enough? xD However feel free to post your engine here
Btw i have bought the game for some reason it dosent show that iam supercharged ):
