Please explain me about code3 midsized S/C pulley, someone may say it will slip under oem belt, today my friend got 299whp on dyno, his car has 178mm pulley on his car and no any tune he decided to see what happens if use 178mm crank pulley with code 3 s/c smallest pulley which is not advised to use with 178mm or bigger crank pulley and code3 3th green filter which installs at upper of throttle, he achieved 329 whp he gained 30 whp, so why I should not do the same, and why smallest s/c pulley does not use with 178mm pulley, my friend gained 30whp in front of my ayes : )). Why we need to use only midsized? If they slip how those 30whp were gained by my friend’s c32 on dyno ? In my opinion if use midsized with 178 + green filter it is possible to get 30whp with smallest s/c cod 3 pulley and 20whp with the midsized one. What do you think about all it?
