Application: Vortech® V1, V2 S-Trim Superchargers; and V2, V3 Sc-trim Superchargers.
Background: The impeller inside the Vortech® S-trim is made from a casting, and is not recommended to operate at speeds above 50,000 rpm.
Today's V+ Impeller: Our V+ impeller is cut from billet on a 5-axis CNC mill, allowing us to use higher-strength alloys, and balance it to higher tolerances. We cut in more aggressive inlet curls and progressive vanes that are computer-designed for optimum flow inside the impeller housing. Each impeller is spin balanced to 0.006 grams/inch, and designed to operate up to 60,000 rpm. This Impeller has been more than a year in development and testing, and is so unique that we have US Patent D588158 on it.
On-car and on-bench testing reveals that our V+ impeller moves about 15% more air ACROSS THE ENTIRE RPM BAND when compared to the classic S-trim impeller. See actual data sheets below from dyno testing. We were able to bring the boost in much sooner, which translates into USEABLE HORSEPOWER. Now your S-Trim Vortech® can produce almost the same 1200 CFM as a T-Trim below 50,000 rpm (impeller speed) and even more if you spool it up to 60,000!
Simple Installation: You can change-out your impeller by removing the scroll and one nut on the end of the impeller shaft. Slide the old impeller out, slide ours on. We designed it specifically to fit within the Vortech® impeller housing without any modifications.
This Isn't Our First Impeller... You should know we've done this before - so you can trust 928 Motorsports® and the results we obtained. Our first billet High Performance Impeller received a US Patent and is available for Powerdyne Superchargers.
