High-Performance Billet Impeller for Vortech® T-Trim Superchargers

Application: Vortech® V1, V2 T-Trim Superchargers

Finally! A solid upgrade for the T-Trim Vortech® models! US Patent D588158

Description: The first high-performance impeller for the T-trim Vortech® models T-trim by 928 Motorsports. Where the stock T-trim impeller is made from a casting and limited to 55,000 rpm, our upgraded T-trim impeller is cut from aerospace-quality 7075-T651 billet on a 5-axis CNC mill, allowing us to produce a stronger, lighter, more aggressive and better balanced impeller that can safely spin 60,000 rpm all day. Our patented inlet curls and progressive vanes 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 is so unique that we have US Patent D588158 on it.

Our T-Trim impeller moves about 15% more air ACROSS THE ENTIRE RPM BAND when compared to the cast basic T-trim impeller. We were able to bring the boost in much sooner, which translates into USEABLE HORSEPOWER.

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.

Hard-coat Anodized: We have taken the extra step of having these impellers hard-coat anodized to give them exceptional corrosion resistance and a surface hardness greater than that of the aluminum alone.

Dyno Tested Performance: Dyno chart below is from one of our customers that replaced his impeller only on his V2 T-trim - nothing else - and picked up 53HP! Engine is a built 6.2L Hellcat with Comp cams.
