High lobes is the issue on anything but a 800+ BHP turbo. High duration and high overlap means lots of cylinder blow down prior to max fill/pressure. Simply the turbo isn't capable of filling the cylinder to max capacity during the power stroke which translates to a loss of pressure = loss of power.

In all honesty, P11 work for a majority of applications. Get P12 if you want 6-700HP. N1 cams for anything else above that.

False - N1 cams work great on a turbo. I triggered VVL at 3200-3400 RPM on my EFR 7163 with N1 cams and they worked great with the turbo.

If a cam works well on a stockish VE engine when it's NA, it'll also work well on a reasonably sized (~400+ rwhp) turbo.

I will walk back my statement as I took internet "wisdom" as some sort of gospel.

N1 cams work well on most medium to large frame turbo setups
