SCI trim = 1050 CFM - 725 hp - comes with kit

I know you already know all of this based on your posts. But why do you recommend skipping the Ti trim? It seems like a perfect fit for a built motor Stillen Kit. It should be able to support 700 whp if you can get the Stillen framework to keep up. That is overkill for a streetcar. The fitment unknowns and cost of fitting a YSi don't seem to make sense to me. Is there a part of this equation I am overlooking?

the v3 gear case is weak and its cfm numbers are overstated, the blower itself is meh before you even get to the crappy volute designs available for it. you run to big of a compressor to fast on a v3 and it will die eventually, the v4 has a better ratio, stronger gears, larger faster bearings and is built to be abused. i know lots of guys with v1 v2 and v3 blowers(or had lol) that the chargers have "broken in" and gotten louder cuz there bearings died. 928 mospo's main buisness is rebuilding the little **** case vortechs when guys realize they are blown. vortechs cfm numbers online are good guesses at best. there is a secret way to get a v4 to put out a torque curve at the same power level as a smaller charger that will murder the smaller charger.
