Supercharger sounds like an interesting idea... but why on a D-series? I mean, I understand you can pull power out with a turbo... but how well woudl it work with a D-series?
I've heard of a JRSCed D16Y7 and it was slow. Slow as in performed like a stock D16Y8 (EX). That's like... what, 20hp compared from Y7 to Y8?
