"Eaton’s new Twin Vortices Series (TVS) is a roots-type supercharger for a variety of engine applications that delivers more power and better fuel economy in a smaller package, for uncompromising, high-performance driving.

The TVS supercharger’s patented design features four-lobe rotors and high-flow inlet and outlet ports that greatly enhance thermal efficiency, deliver higher volumetric capacity, and enable higher operating speeds. The TVS supercharger is capable of running with a high thermal efficiency (up to 76 percent) across a very wide operating range.

The improvements incorporated into the TVS design allow for the use of a smaller supercharger, reducing the package size and weight of the system. The sizes range from 350cc to 2300cc per revolution, and cover engines from 0.6 liter up to large displacement V-engines. All TVS superchargers have a 2.4 pressure ratio capability and a thermal efficiency that exceeds 70 percent, which enables more compact packaging and greater output.

The twin four-lobe rotors feature 160-degree twists. The higher helix angle of the rotors coupled with a redesigned inlet and outlet ports, improves the TVS’s air-handling characteristics without increasing the overall size of the unit. The TVS improved noise and vibration characteristics eliminate additional noise-reduction treatments, complexity and system cost.

The TVS sets a new standard of boosting device performance and reaffirms Eaton’s leadership in the performance automotive market!"

 

So how are these going to compare to the standard MP112/MP122?

Release dates?

 

 

glad I dont need to keep that secret anymore........whew.

Looks like there is a new player in town....stand by for the info as it comes in.

All I can say is, "screw what?" "TT who?"

 

maybe i'm reading into this way too much but it seams that bassed on the compressor chart for the 1900 vs the m112.. the m112 creates more flow sooner till about 11000rpm or so compressor speed

 

@ 1.4 PR/6000rpm the R1900 is approx 10% more efficient

 

ok.. but what efficiency are we talking about here... maybe i just don't know how to read the maps... but it looks like at lower compressor speeds the m112 has a higher inlet flow.. isn't the efficiency the thermal efficiency

 

typically the island is expressed as adiabatic efficiency (%)

 

@ 1.4 PR @ 6000rpm the m112 is showing approx 650 cubic meters per hour vs the R1900's 600 cubic feet per hour. multiply the cubic meters per hour x.589 to get cfm. Then factor in efficiency and they are pretty close.

I gotta go get some sleep
