I don't get this,

I've read in a book that during the combustion of a 4 stroke engine the force in there can exceed 1000psi. Now, how will that extra 7, 10, or more psi that a turbocharger creates make a difference in such large numbers?

Thanks.

It's because you're misunderstanding. The 1000psi is based upon the pressure that the expanding gas/heat makes during the explosion, and the piston is in the position to accept those pressures. The 7psi that a turbo applies is the intake charge pressure. This is going in during the intake valves' open duration.

Ok thanks.
