GTX 155 NA Impeller Question
How do you guys think a 12/20 Solas would do on a GTX 4Tec 155 NA with an aftermarket intake and grate?
I know the 11/19 is what Solas recommends, but I was able to aquire one for a great deal. Can anyone advise?

its gonna be too much. 12/20 is too much for a stock GTXSC.
it dropped my rpm to around 7100-7200 in the summer heat, thhats on a stock GTXSC.
So on a 155 its gonna be worse i think.
you could try it, get baseline rpms, and then get it repitched to hit 7600 again.
or resell it for profit and keep lookin for a 11/19
