Was 10lb lower and 4.0 upper for 20-21 lbs
Going to 8lb lower and 3.0 upper looking for 25-26lbs
3.250 upper and 8lb lower just saw 26/27 lbs.
Just put a 3.250 upper on with 10lb lower and saw 29-30 psi and had to let out immediately
Not sure, that part of my post was from several months ago and guesstimating boost levels off what little info was out there based on the 2 or 3 data points blower slut had. The pulley size to ratio is all correct info though.So why am I seeing 22 pounds with a 3" upper and 8lb lower
That's probably the closest comparison for me since we've got almost identical JLP powertrain combos. Pretty sure I'm going to do an 8 lower instead of my 10 lower, and see where that lands me.10lb lower and 3.5in upper = 24-25 lbs
10lb lower and 3.25in upper = 27 lbs
I don't have testing in a bunch of different air temps yet.
