I generally short-shift at 6000rpm, but in a lot of cases, I'd shift then immediately brake and have to downshift again; not worth the shift time, so I wind it out. But of course, the N54 falls on its face after 6000rpm or so. So I want something that'll keep the boost up and the torque flowing to redline.
More than 500rwhp I don't think would be terribly useful on the courses around here without very serious chassis mods to fit wider tires and significant downforce, so thats my engine goal. I want it to be reliable and consistent at those power levels and not be working its ass off.
So a medium size single or twins would be ideal, I think. But right now the setups just seem too "fragile" for lack of a better term. I want to simplify, simplify, simplify. "
