At the 2016 SEMA show Eaton unveiled their largest TVS supercharger ever.

• 15% more displacement
• 25% more air capacity
• Less heat through specially tuned rotors
• Edelbrock, Magnuson, Harrop, Roush and Cosworth are aftermarket suppliers for it.

 

very nice; i don't know how good it would be on a larger v8 engine;
what is the basic limit on what this can feed

Eaton's biggest markets are OEM and modern smaller displacement engines. You wouldn't want one on a 454, but it'll shine on a 6.0L, 5.4L, 5.3L, 5.0 or 4.6L. I can't wait to see what kind of numbers it puts out.

 

The TVS blowers actually have much higher efficiency than twin screws until you get past 16 psi. After 16 psi though they lose that advantage, it's only by a couple percent.

 

Another interesting tid bit, one of the things Corvette did is a trick Roush has been using since 2004 (maybe others before, I don't know the full history).....

From 2004+ Roush superchargers in the F-series used electronic control of the boost bypass based on RPM and pedal position. With these systems when you smack the throttle it reacts slightly faster than a vacuum only system.

It helps off the line launches as well as throttle response from a roll. It also helps mileage since you can keep the engine from boosting a light throttle when you don't need it, whereas a sole vacuum system the change in vacuum might be enough to close the by-pass.
