hmmm...now i'm curious how spool/transient response/power output would be if i were to swap to that.....not that i need to swap haha.

idk, your compressor wheel looks very similar to my 20g did....also blouch....but it is possible it's been upgraded.

so the flow rate of both the xtr and g2r is 49lb/min.....i'm curious to know what the difference is between them, may have to reach out to blouch for that. but based on the flow rate, and the fact both have 8cm or 10cm hotsides, so no difference there, you'd think it would make the same power out of each...my only guess here is that maybe they lightened the turbine wheels and get a little faster spool up and transient response? i'm just shooting in the dark here lol

i'm excited to see people running the g2r, i think it could beat out the 1.5, which is my favorite of the stock location offerings i have experience with (which, from working at a shop, is alot lol)
