Go to vortech's website. Click manuals and tech info, impeller speed calculator, then fill out the info for the V2/V3. It's about 49K RPMs as Stillen sells the kit. There are multiple people on the 350Z forums turning their vortechs over 60K RPMs for years. Then when the bearings fail, send the unit to vortech for a rebuild or trade up to something better.
