I’m at 8PSI with 9lb pulley and Si. Elevation plays a factor but no leak pretty sure we tested when I was at 7lbs with stock 8lb pulley. Sounds like turtle’s filter is giving a huge drop.
How long have people ran with no filter just screen? The idea terrifies me with rubber belt dust getting in boosted piping seems like a matter of time before it finds it’s way through the valves into cylinder but clearly huge gains to be had.
I remember somebody explaining something I believe to Patrick about if you change to small pulleys it can over power the filter somehow decreasing boost? Don’t remember but elaborate if that phenomenon rings a bill.
Anybody tried doing their own tunes? I would play around with pulleys and filters more if I could be tweaking my own tunes otherwise it’s too much of a hassle
