here's the scoop

new MP112H = 1.8L displacement, new housing, new high helix rotors

new MP122H = 2.0L displacement, new housing, new high helix rotors

current MP112 = 1.8L displacement, existing housing, current 60deg tri lobe rotors

 

not to sound too stupid what is exactly the difference between the regular and the HH? More twist in the rotors?

 

yes, more twist

 

more whippleish then?

 

No, a Whipple is a screw....Male and Female Rotors. This is a Hybrid Roots style supercharger, nothing like the Screw.

 

Gotcha. Just twisted rotors. So what kind of degrees the standard/older is 60*.

 

old is 60*, new HH is 70* (i think)

 

got it.

 

Thanks guys, good info.
