See my post from last night--apparently these things run about 8 psi of
boost when feeding their stock app. engine.

So--they should be pretty reasonably efficient in stock form at that level
of boost--truckers are pretty darn sensitive about fuel mileage, after
all--it is their bread and butter!

But--when you start asking one of these huffers to make two or three times
as much boost as it was designed to, then the better seals would become
pretty important in a BIG hurry!

Prolly the same thing goes for stronger end plates and better bearings when
there is more load on the blower!
