who knows? do you still have to drill an oil line for a roots blower?

no you don't have to drill a line on the KB....the mfg install times are about the same. Never having installed a KB, the Vortech was straightforward, and I expect the KB would be also.

KB install is a bit more indepth with removing the manifold and all - but if you can change out an intake mani then you can do it. Centri FTW though

I like Centris for street driving because you can stay out of the boost easily if you want but with our heavy ass cars the KB is the way to go.

I can stay out of boost at will. I can drive to California and back without hitting any boost. I wonder what kind of KBs some of you guys are talking about because mine only hits boost when I punch it hard, low rpm or high..

KB is a Twin screw, btw
And from what I hear its not hard to keep out of boost in regular driving

Twin screw and roots are two different types of blowers, the main difference being in the rotor design. They are both types of positive displacement blowers.

Short version…..

Twin screws utilize an intermeshing "screw" type design with tight tolerances that draws air in from the inlet side and compresses it between the screws inside the unit itself in order to build manifold pressure before discharging it into the intake.

Traditional "Roots" blowers utilize a pair of lobes that draw air in from the inlet side like the Twin Screw, but paddle air around the lobes while moving it from the inlet side, to the outlet end of the blower where compression takes place after the fact, within the intake manifold.

Each have their high points and low points but both will get the job done when you want to make a ton of low end torque.
