Just completed installation of a Whipple SC Stage 2 on my 2012 Velocity 290SC with HP525 / XR Racing Drive (16.2 hours on motor). This is the Velocity Boat that was in the 2012 Miami Boat Show. Earlier this year on Lake Monroe-Florida Steve S (Velocity)., Ken H. (Velocity) and Chip from Poker Runs America did an evaluation (see at Velocity site) and saw GPS speeds of 85 MPH with a 29" pitch labbed Hydromotive 5 blade prop. We are now easily in the low to mid 90's with 30" pitch labbed 5 blade Hydromotive prop and expect speeds close to 100 when running light / trimmed out. This install is not for the faint hearted -- lots of parts and things to do CORRECTLY. Expect to sink $20,000 in project (if done CORRECTLY) before you are done. If considering this project I would suggest downloading the Installation Instructons PDF from Whipple to get a feel for the magnitude of this undertaking. I have also listed some excellent resources below if you are looking for more information.

The following resources provided valuable service on this project:
JebCo Performance Marine Engines (Jay OSOid = CubicInches)) – SC Installation and extensive engine component rework / SC tuning. ** Hydromotive Engineeering (Todd) – Consulting on correct prop for SC install. ** CP Marine (Mike) – Gauge info and ordering. ** Livorsi Gauges (Fred) – Gauge Info Support / Control Support ** Mercury Racing – Smartcraft Raceview Gauge hook up info. ** Whipple Superchargers (Dustin Whipple) – Provided valuable personalized consulting throughout the project. ** Velocity Powerboats (Ken / Steve) -- Ordered parts (sea strainer / other) – Input on intercooler pickup location. Input on Smartcraft Interface and Mercury Network. ** Jim Raymond Marine Service (Jim OSOid = jray10) – Livorsi control support, drive support, installation of SC gauges for intercooler input pressure and fuel pressure(has to run 50+ pounds). Jim installed the throttle cabling and shift box (had to be installed on stringer because of space constraints created by the SC. Jim did all the computer analysis. Jim used Redline Lubricant to allow the XR Racing Drive to run cooler. ** Fast Forward Fiberglass Repair (Scott and Matt) – Installation of intercooler water pickup, installation of intercooler overboard spent cooling water fixture, preliminary plumbing, sea strainer installation, physical installation of gauges on dash and gel coat repair. ** Everett Performance (Paul) (Zeiger Performance Marine) – General Consultation. ** OSOid = NYSPOWERBOAT (Nolan F.) provided valuable input throughout the entre project and also is working on installation of mirror bottom side of engine hatch.
