EATON-twin screw video
cant wait, this is going to open the doors wide open for us....EATON reliability with high efficiency

im so glad eaton did this, guess all the eaton h8rs will have to find another form of forced induction to loathe

Keep in mind we have had the same video on the site for quite some time now.

The new TVS superchargers EATON is producing aren't twin-screw superchargers. They simply feature four-lobe rotors (vs. three on previous models) and high-flow inlet/outlet ports to enhance it's thermal efficiency and volumetric output at a higher-RPM than previous roots-style superchargers.
Still, it's excellent news for the LSJ folks!

I'm not trying to being a jerk and argue, but I would hate to see this community start purchasing the TVS supercharger(s) and telling every one they have a twin-screwed Cobalt.
The new TVS sc is still concidered a roots style, it uses 2 hi-helix 4 blade 160 degree helix rotors. However it is NOT a twin screw, twin screw sc have 2 different rotors, a male (usually 3 blade) and a female (usually 5 blade) the twin screw uses internal compression meaning it compresses the air INSIDE the casing of the SC rather than stacking the air in the intake manifold like a roots style. However this new roots style design may give twin screw sc a run for their money. One of the down falls of a twin screw is that yes it does create less heat under high boost, but under normal driving conditions because it uses internal compression its ALWAYS generating heat unlike the roots which ONLY generates heat while under boost.

Here is a site that explains the differances between the two and more.

the tvs R1320 is aparently a 1320 cc per rev unit wich works out to about 80.5 cubic inches in other words it falls just between a m62 and a m90 if i can get my hands on one thats the unit ill try to get.
