Here's a link to the short-runner unequal length manifold experiment.
Below is a comparison with a RevHard T3 Cast manifold with 0.63 A/R turbine housing and his custom short-runner unequal length T4 TS with 1.06 A/R. As you can see, the short-runner spooled 400 RPMs sooner even with the larger T4 1.06 A/R turbine housing!
