Hey guys, finally got my 3 bolt timing cover and ysi installed on the Mach 1! I’m going back and forth about piping size after the head unit. I have a pmas hpx-e made for a 3.5” pipe, so I was thinking I’d run 3” from the head unit to the fmic, then size up to 3.5” from the intercooler outlet to the throttle body. Car should be making around 27lbs of boost and the intercooler has 3” inlet/outlet Would that be fine, or should I just run 3.5” all the way? Any thoughts or suggestions?
