Turbo sizing

I learned a thumb(?) rule(???) inducer(mm) x inducer(mm) / 6 = Max hp for compressor.
lets say a 76mm china turbo. 76x76/6 = 960HP.

if you going stock bottom end, I would put in a bigger camshaft in it with much overlap and tight LSA to get away with cylinder pressure. You do not get alot of power in the low rpms, but much more fun i the top, and its easier for the engine! its the cylinder pressure that destroy the engine!

I believe there is no such thing as a "turbo" camshaft. you may turbo any camshaft! at 14psi, your power output is aprox doubled over NA power. build yourself a nice crisp 400hp engine and turbo it.7psi - 600hp 14psi - 800hp...

good luck! :-)
