what is the difference betwwen the 112 and the High Helix and the 122? anyone have info as to what they are all capable of?

 

122 has more volume and capable of more horsepower

 

The HH will make more mid range and top end power than the regular 112. You'll see about a 1psi increase. As mentioned, the 122 is capable of higher hp.

 

Moregrip (i think) did a big write up on the evolution of the Roots style superchargers. As stated above the 122 is larger, the HH is more efficient.
Efficiency is what we want, less parasitic loss and less heat generated at the same output level.

That's how I read it.

 

When I was shopping around for my maggie, I spoke with Lingenfelter and had the best analogy.

"The 112 on anything over a 6.0L is like trying to fill up a bath tub with a coffee cup, the 122 would be like using a 5 gallon bucket to fill it up...much more efficient..."
