KENNE BELL 2.8L vs EATON 122 (2.0L) SAME 3" PULLEY
How does the latest Eaton 122 (2.0L) Roots type, which is even larger than the Eaton 112 (1.85L), compare to the Kenne Bell 2.8L Twin Screw kit with the same 3” pulley, custom tune (23° 11.5 AFR), stock inlet systems, etc? To make 125HP at the same supercharger rpm, there must be something better about the Twin Screw. The Kenne Bell 2.6 and 2.8 are simply larger displacement more efficient superchargers that produce higher air flow, boost and HP - and they consume LESS engine HP to operate.




RESULTS: MORE HP, LOWER PARASITIC LOSS, HIGHER BOOST, LOWER TEMPS

Note: This test was performed on the ‘07 Shelby Cobra as it is the only factory produced vehicle with the 122. At 23 psi, the 100% stock Shelby made 801HP!

I hope the this posts up well. I found this at the bottom of the Corvette section on the Kenne Bell web sight. I though it was a pretty interesting test. I also think it's crazy that it made 801HP at 23 psi of boost! (I'm almost positive that's to the wheels)
Enjoy.

 

Sorry, I don't know how to get the graph up. I'm retarded
Here's the link, it's at the bottom of the page.

Like you said in your post....The screw was a bigger blower.....like comparing apples to oranges. You can enjoy the fun for now, once the new **** hits the streets....KB and Whipple might need to spend some money on R&D for a new blower.

Just my opinion of course.

 

As I understand, it was to the wheels but on race gas. Still awesome! Factory stock with a blower change, why does Chevy make it so hard for us.

 

Hey Brian, you back to running the radix or still running the sts....you probably have said in another post, but I haven't seen it.

 

Still running the STS, waiting for my TVS

 

Once the Eaton TVS hits it's gonna blow everything out of the water

 

the twin screw is simply more efficient no matter what size either is than any roots or roots hybrid on the market currently (excluding TVS)
