Sounds like your good.The reason I asked is cause my whipple setup was quiet a bit smaller behind the tb causing a restriction on the blower.Just wanted to check if yours was the same way.Keep us posted on dyno results or tracks times.

 

Welcome over! I had no idea Vortec made a twin screw s/c. Cool stuff, keep us posted.

 

saw that a while back on tx that vortech was gonna come up wuth a twinscrew wounder if its better then the maggie

 

100 bucks says NO

 

6.5lbs on a 5.3 with only a 4" pulley?

 

Yeah 6.5 lbs and that is at 5200' (with a barometric pressure of 84 kPa or 12.2 PSI) and it builds boost super fast. I'm sure it would be closer to 8.5 at sea level. This Lysholm twin screw is a beast.

 

 

Thats alot for such a small pulley. I wonder if it is as efficient as the tVS at higher PSI's.

 

Here is a link to a pdf with some of the efficiency specs:

I haven't looked at the efficiency of the Eaton units, but generally twin screws are more thermally efficient. Twin screws compress air in their housing and not the manifold of your engine.

 

Therefore they are always compressing......making them less efficient.
