Fast spool for sure, but I didn't like the topend loss. I still always recommend the .63 to anyone over the .48 for street or strip.
Another thing to remember is the AGP 50trims spool faster then your typical Turbonetics. A Turbonetics .48 50trim won't hit full boost till around 34-3500rpms.
I was talking about my 60-1 at the 4k. I have the ball bearing 60-1 on right now but am looking at getting a 50trim for the faster spool and stronger powerband for around 20/22psi.
