Not looking for a "who" can out tech "who" kind of discussion. I know little about turbos other than the principle of using exhaust gases to spin it.
I read posts about .48 and .63 along with a stage 1,2 or 3 turbine wheel and a 46 or 50 trim.
In other words, turbos for dummies. I'm sure there are many other that would like to know also.
Round 1....ding, ding!
