To Twin-Scroll or not to Twin-Scroll, that is our Question of the Week

In the Subaru community, the Twin-Scroll turbo configuration that was used on the JDM STI starting with the Version 8 STI is considered the ideal turbo setup. There are a couple of reasons for this. The main one is that a twin-scroll turbo uses an equal length manifold, and it splits the exhaust pulses up into 2 completely separate sets of pipes all the way into the turbo. This allows for the optimal pairing of exhaust pulses to in theory maximize the spool characteristics of the turbo. The equal length manifold also performs better in high rpm ranges, so the twin-scroll turbo should have better top-end performance than a comparable single-scroll turbo. On paper everything points to why a Twin-Scroll turbo will perform better. So when we set out to build our Pikes Peak race car back in 2013 and 2014, that is the path that we decided to go down. So what is involved in a Twin-Scroll Turbo Conversion? And is a Twin-Scroll turbo really that much better than a comparable Single-Scroll turbo? To answer this question of the week, we went back and looked at all of our results with the various twin-scroll turbos that we have tried on our Pikes Peak Race Car and did our best to put all of that information together here.
