have a built motor and going to be running a wastegate setup. Boss intake and a f1a head unit with the race intercooler. Trying to decide which pulley to use and what would work better. Target boost is 20psi. I wanted to get the most out of the midrange as I can and still be efficient up top and make the 20psi. I have a 5 inch pulley on it now and it peaks around 13.5 to 14. I punched in two pulley sizes that I thought would get me close to the 20 psi. Choice is do I want to use a 4.38 pulley to 8k(blower rpm is right at max) or run a 4.25 pulley and shift at 7700(blower rpm is just over 73k) trying to see pros and cons of each. It will rarely taken to redline since I don't get to race much at all. Maybe once a month
