Does it come down to forces then...? or just purely what's applicable? why could a Scoob run a Baileys twin piston with 2.5L but RB Skylines I only ever see with BOV's? (generic I know)
Got me thinking on twin scroll turbo's now too, would they always need a DV? could you still stall them with big boost?
