Not good at teaching, but you have to find the proper balance of compression, ignition timing and boost along with getting the cam value right to match the low end power and vvl for high end. Also make sure the engine is over square to keep piston speed down to keep reliability at a decent number. Also, use cast iron heads and block. I6 also seems to be the most efficient way of making power with hilarious fuel economy. I could get an I4 to around 140 points but no higher.
