Upgraded my Vortech V1 to a "Super Vortech". I couldn't be happier with the performance out of a 20+ yr old supercharger on my 1996 LT4 Corvette. The difference with the 928 impeller vs the standard trim impeller was pretty amazing. Thanks! Jeff K.
Overview: This is our maximum rebuild for all Vortech T, S, Si and Sci-trim superchargers. The finished Super-Vortech® will move 15% more air at all speeds, the boost will come in sooner, and the rev-limit for the supercharger will be higher.What we will do to your Blower
Our Patented Vortech® S-trim Impeller Upgrade: 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.
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!
The 928 Motorsports High-Speed Ceramic Bearings: We have found the right combination of ceramic ball bearings, HHS bearings races, and high-temp phenolic bearings cages to allow safe increases in rpm's compared to stock Vortech® impeller bearings. Previously, the operational limits for the stock bearings on the superchargers listed above was 53,000 rpm. Our Premium High-Speed Ceramic bearings are rated at 72,000 rpm in oil, and can run in the high 60,000's+ all day. Accept no substitute! If you think your going to spin up your Vortech a little faster for more boost - these are the bearings you need.
The 928 Motorsports Premium High-Speed Seal: Our seal is made from the finest materials for a long life, plus it has a broader sealing range than the OEM seal, so leaks don't happen!
