Hey guys,

Check it out, Eaton just released info on thier new superchargers.

I wonder about real world spec, cost, and boost????

I wonder about real world spec, cost, and boost????

The site specified above has specs on the units along with compressor maps. The TVS maps go up to a pressure ratio of 2.4 which is around 20 lbs of boost. Efficiency peaks at around 76% which is 10% higher efficiency than any other positive displacement unit available.

Another thing to note is the RPM capability of these units. Some of the maps show the S/C being spun up to 21,000 RPM which is 7K faster than what the 5th gen units were rated at. Simple math shows a TVS unit can offer up to 50% more flow than the previous gen blowers of the same displacement. This means a smaller blower can be used to get the job done that previously required a much larger blower. Smaller blower means less mass to spin, less parasitic losses, more efficient, etc.

Doesn't look that diff from the old eatons...
hell the one on my buick looks almost identical to the one in that pic.....

You'd surprised at what a couple degrees of change to parts of the lobes could do for efficiency. Let alone minor changes throughout whether it be rotor clearance, displacement, radius of bends.

Small changes make a HUGE difference.

I want one, it wont be the badest on the streets, but I figure I could put my motor close to 700 at the tire.
