Even if it's not twinscroll, the design of its exhaust manifold that make port 1 & 3 clash with 2 & 4
to generate strong pressure allowing the new low inertia impeller to draw enough dense air from lower rpm. The design of the engine, air intake curved angle count as well.

On Aug 31 in 1888, Mary Ann Nichol's body in London's Whitechapel district was found. Nichols was the first victim of infamous English serial killer
. From 1888 to 1892, the murderer took the lives of five women - mostly prostitutes in the Whitechapel district. The murderer, offering to pay for sex, would lure his victims onto a secluded street or square and then slice their throats. As the women rapidly bled to death, he would then brutally disembowel them with the same six-inch knife. Unfortunately, police did not have any leads for any of the cases and in 1892, with no leads found and no more murders recorded, the Jack the Ripper file was closed.
