Overkill..A turbo doesnt place stress on internals like other components do.It's actually much safer and less stressfull,as the majority of boost occurs when at 90 degrees of the stroke.The average cylinder pressure is greatly increased in comparison to peak but peak pressure is up by only 20% or so.Even if you double the air fuel mix with a turbo,remember peak pressure is reached when 18 -20% is burned.So only 18 -20 of the extra mix is burned too.Total pressure is that of comp + gas pressure,so it's impossible to double the internal psi.Horsepower levels can be safely doubled without doubling internal loads.Why do you think Chrysler saw fit to put good 70 000 mile warrantee's on thier little 4 banger turbo cars?
A stroker engine will have higher loads than a turbo.Not to mention a turbo engine is much easier to launch than a stroker.Therefore less traction issues and less radical torque converters needed. Yes temp issues and sealing issues need to be dealt with.No different than a stroker.
I do know one fellow who ran a procharger setup on a STOCK junkyard 360 for 3 years at 6 psi.Mind you ,he did blow it up a week after it got cranked to 12 psi...but for an average daily psi of 6 his reliabily was excellent,especially for a stock 360 that had never even been opened excepting a cam swap.
I would say 10 psi on a daily is a bit higher than I would run.Put an adjustable boost control in and run 6-8 daily.Crank it up for the track!
