Psi with pulley’s on SI Trim

Ilusivefox said:

Every engine is different but that pulley combo is spinning the impeller to just under max speed at 6000 rpm. Probably 15lbs

Max boost is 26#

I know this is an older post but to update this thread. I still run the 8" Renegade pulley and a 3.33 upper. I made 13-13.5# of boost at 6k. Hope this might help someone down the road or doing a search anytime in the future
