The Whipple uses Eaton built (i.e. superior quality) Lyshom twin-screw rotors. The KB uses Autorotor built twin-screw rotor packs, however Autorotor recently altered the screw design to be less severe, thus allowing them to no longer pay the Lyshom license fees. This results in a bit of boost drop off at very high boost levels. The Whipple is also a rear inlet, which is the proper design for an axial twin-screw blower, as opposed to the KB's top inlet, which reduces efficiency by about 10% according to KB. My Work 140 gives me 24 lbs of boost with the current pulley setup, and according to Whipple, it can make close to 30 psi. As for the KBs, while they are not my blower of choice, you are still incorrect about the boost, as I have many KB customers running well over 22 psi.
For the Mustang yes, but the truck KB is a top loader...JT said:The '03 case looks to me to be a rear inlet, the TB tube comes in at the side of the rear of the blower.
Yep, we are on the same page, I was just confirming that the '03 case is different than the Lightning case, and that it doesn't have the "toploader" limitation, if it even is a limitation.Ayrton said:For the Mustang yes, but the truck KB is a top loader...
